Course Creation Settings

When you add a new course or click the "Modify" link next to a course name, enter the course name and an enrollment key. If you are allowing students to self-enroll then the enrollment key should be given to students, and will be required for them to enroll in this course, along with the Course ID. For new courses, the course ID will display when you return to the Admin page.

Other option:

• Enrollment Key: A entry password for students to self-enroll in the course. If you provide a semicolon-separated list of keys, students can enroll with any of them, and the key will get recorded as the student's section
• Available: Whether course is available to students, and whether it should display on the instructor's home page
• Lock for Assessment: Shuts down access to the course except for the specified assessment. Intended for in-class testing situations.
• Theme: Change the look and feel of your course
• Icons: Whether to display icons next to different course items.
• Allow self un-enroll: Whether students should be able to unenroll themselves from your course (usually NO is the best choice, so students can't accidentally delete their scores)
• Allow other instructors to copy: Whether other instructors should be allowed to copy course items without needing an enrollment key. You can limit this ability to instructors in your own group.
• Message System: allows you decide which features of the internal messaging system you want to enable. This allows you restrict who, if anyone, the student can send messages to.
• Live Chat: Enable a live chat room for this course
• Student Quick-Pick Top Bar: What items, if any, to have in a bar at the top of the student's course page
• Instructor Quick-Pick Top Bar: What items, if any, to have in a bar at the top of the instructor's course page
• Instructor Course Management Links: Whether to have course management links at the bottom or along the left side of the instructor's course page
• LTI access secret: A secret code to allow placement of your course into a BasicLTI consumer. More info

Transfering Ownership

Deleting

Manage Question Set

Clicking the "Manage Question Set" link will allow you to search through the Question Set, modify questions, add questions, remove question, transfer ownership, or add a set of questions to a question library. Only administrators or question owners have the rights to remove a question. Be aware that if you remove a question that is currently being used in an assessment (as shown in the "Times Used" column), it will mess up that assessment.

The options available in the question set manager are:

• Modify: Change the source code of the question and make library assignments. You will only see this option for questions you own or when the owner has given permission for anyone to modify the question.
• View: View the source code of the question and make library assignements. You will only see this option for question you do not own.
• Template: Create a new question, using the code of an existing question as a starting point. When you template a question, the original question is not changed.
• Delete: Delete the question completely from the questionset and all libraries. You will only see this option for questions you own or when the owner has given permission for anyone to modify the question. You can delete many questions at once by selecting questions with the checkboxes, then clicking the Delete button near the top of the page.
• Transfer: Transfer ownership of the question to another user. You will only see this option for questions you own. You can transfer many questions at once by selecting questions with the checkboxes, then clicking the Transfer button near the top of the page.
• Library Assignment: The Library Assignment button near the top of the page can be used with the checkboxes to add or change your library assignments for the selected questions. This will not affect other people's assignments

Note that the assignment of questions into libraries can be done by anyone, but only the person who made the assignment is able to remove the question from the assigned library

Export Question Set

Import Question Set

Use the "Import Question Set" feature to import a Question Set that you or someone else had exported from IMathAS. Be sure to only import question sets from trusted sources. After specifying an import file, you will be given a chance to select specific questions from the set to be imported.

Imported questions will have ownership assigned to the importer. Select the userights you want to apply to all imported questions. You also can import the questions directly into an existing or new question library

If any questions (identified by a unique id) already exist in your system, you will be asked if you want to update the existing questions, or add as new questions. If you have modified questions previously imported, you may want to add as new.

Manage Libraries

Use the library manager to remove, rename, change rights, change parent, or transfer ownership of question libraries. Be aware that if a library is deleted, the questions in that library will become unassigned; they are not deleted.

Libraries have a tree structure, where each library has a parent library. When you add or modify a library, you can change it's parent library. If you change a library's parent, all children library move with a library. You can only specify an empty library or existing parent library as a parent.

Libraries have use rights. Options are:

• Private: Only the owner or an administrator can list questions in these libraries
• Closed to group, private to others: Anyone in group can list and use questions, , but only the owner or an admin can add questions to the library. Hidden to anyone outside the group.
• Open to group, private to others: Anyone in group can list and use questions and add to the library. Hidden to anyone outside the group.
• Closed to all: Everyone can list and use questions, but only the owner or an admin can add questions to the library
• Open to group, close to others: Anyone in group can list and use questions and add to the library. Outside the group, users can only list and use questions; they cannot add questions to the library
• Open to all: Everyone can list and use questions and add to the library

With library rights, child rights take precedence over parent rights. For example, if an open library is a child to a private library, the parent will not be hidden from other users. However a private library as child to a private parent will be hidden from other users.

Depending upon the system configuration, non-admins may be limited to creating libraries that are private to others outside their group. If this is the case, a non-admin will need to contact an admin to create a library that is closed or open to all.

Library assignments are done in question management. Library assignments can be done by any user, but only the person who made the assignment can remove that assignment.

Export Libraries

Import Libraries

Use the "Import Libraries" feature to import an entire library or tree of libraries. After selecting a file, the tree of libraries in the import file will be shown, and you can deselect libraries you do not want to import. Note that if a parent library is not selected, NONE of the children libraries will be added, regardless of whether they're checked or not.

You will be asked if you want to update existing questions/libraries, or add as new. If a library or question (identified by a unique id) in the import already exists on your system, this will tell the importer whether to update the existing libraries/questions, or import the libraries/questions as a new copy (a new unique id is assigned). If you have modified questions previously imported, you may want to add as new.

Imported libraries and questions will have ownership assigned to the importer. Select the userights you want to apply to all imported questions and libraries. You can select a parent in the library tree for all (top level) imported libraries

If you load a file that does not have a library tree embedded in the file, you will be told to use the Import Question Set feature instead. Even if a file has a library tree, you can use the Import Question Set feature to import specific questions from the file.

Import Students from File

The form will guide you through specifying which columns of the CSV file contain First name, Last name, email address, and desired username. Once setting these options, the first five rows of the file will be displayed so you can verify that the import settings are correct. The students will be both registered and enrolled in the current class upon submission.

Assigning Section and/or Code Numbers

Click the "Assign section and/or code numbers" link to assign section or code numbers to students. These only serve for identification purposes, the the gradebook will be sorted first by section, then by name. Section can be alphanumeric; code number must be numeric, up to 4 digits.

Manage LatePasses

Click the "Manage LatePasses" link to give students LatePasses. Students can redeed a LatePass for an extension on an online assessment without your intervention, provided you have clicked the "Allow use of latepasses" option in that assessment.

On this page you can also define the number of hours extension a LatePass will grant

Manage Tutors

Click the "Manage Tutors" link to manage tutors for your class. Tutors can have an instructor account or student account. Tutors will be able to view students' scores and online assessments. If given permission, tutors can edit or enter online or offline scores.

Add tutors by listing their usernames in the box provided. Remove tutors by clicking the "Remove" checkboxes next to tutors and clicking Update

Once tutors are added, you can limit them to a single section of the course. If selected, tutors will only be able to see scores for students in the section they're limited to. This can be used in conjunction with the diagnostic system, since second-level selections become the student's section identifier

Gradebook Settings and Categories

Click the "Gradebook Settings" to change Gradebook settings and create or modify categories. This allows you to create a grading scheme.

Your overall settings are:

• Calculate total using: Select "points earned" to use a points earned out of points possible grading scheme. Select "Category weights" to assign a percentage weight to each category in calculation of total grade.
• Gradebook display: Select whether to order the gradebook by item dates (Available until dates for assessments, Show After dates for offline grades) or if you want to group items by category

The next section lets you define categories. There is always the "Default" category, but it will not display if there are no items assigned to it. To add a new category, click the "Add Category" link to add a new line to the table, then fill in the name and other info, then click "Update"

For each category, you can specify:

• Name: The name of the category
• Scale (optional): Scale the category total by specifying a point value or percent value to be scaled up to 100%. For example, if the category point value was 80 points, and a student earned 50 points, their category total would be 50 points. If you specified a scale of 60 points, then the students grade would become 80*(50/60) = 66.7 points out of 80. You can specify whether grades that would end up over 100% should be chopped to 100%. You can specify no scale by leaving the Scale box blank.
• Drops (optional): You can specify whether to drop the lowest N scores, or keep the highest N scores from the category. Set the number to 0 to keep all scores.
• Weight/Fix Category Point Total: If you are using a "Category Weights" grading scheme, enter the percent weights for each category here. If the category percents don't add to 100%, they are all scaled equally so they do add to 100%. If you are using a "Points earned" grading scheme, you can fix the point value for the category here (optional). For example, if the current category total is 50 points and a student earns 40 points, if you specified a fixed point value of 100 points, the students score would become 80 points. Leave this blank to use the actual category point total.
• Remove: When you remove a category, any items currently assigned to that category will be assigned to the Default category

Offline Grades

• Name: The name to give the grade item
• Points: The number of points possible on the item
• Show to students after: The date after which to show the item to students
• Gradebook Category: The gradebook category you wish to assign the item to
• Count: Whether to count the score in the gradebook total, not count it, or count it as extra credit
• Allow tutors to edit: Whether tutors should be able to edit scores for this item

You can then enter grades for each student. If you leave a grade blank, no grade will be recorded for that student. You can edit these settings or edit all students' grades at a later time by clicking the "Average" in the gradebook for this item. You can edit an individual student's grade by clicking on their score in the gradebook for this item. You can leave feedback for students about their grade using the boxes provided.

You can manage offline grades by clicking the "Offline Grades: Manage" link on the gradebook page. This page allows you to delete, change the availability, or change the gradebook assignment of a set of offline grade items.

Gradebook Detail

When you click on a student's score in the gradebook, you will see the specific assessment that they received and the last answer they provided, as well as their score on each question and the attempts used. You can override the scores they received on this page. You can also send a student a message about a question, quoting their version of the question in the message. At the bottom of the page is a box to leave the student feedback about the assessment.

If you wish to give a student another chance to take an assessment, click the "Clear Attempt" or "Clear Scores" link. Note: This will clear their current scores, answers, and attempts used. The "Clear Attempt" link will make it appear the student never started the assessment, and the student will receive a different version of the assessment when they access the assessment. The "Clear Scores" link will clear the student's scores and attempts to 0, but the student will receive the same version of the assessment when they access it.

If you categorized the questions in the assessment, you will also see a category breakdown at the bottom of the details page

Canvas Integration - Using Import

Go to Course Items → Export, select the items you want to export, select your LMS, and Download the Export Cartridge

To import the cartridge in Canvas:

• Go to Settings, then Import Course Content
• For Content Type, select Canvas Course Export Package. Select the export file from your computer, and select All Content. Click Import.
• If you have a global college-wide key and secret, you do not need to set up a course-level configuration. If you need to set up a course level configuration, in your Canvas course:
  • Go to Settings, then Apps, then View App Configurations
  • Locate for the IMathAS App. Use the gear icon dropdown to select Edit
  • For the Consumer Key, enter: LTIkey_####_1, where #### is your Course ID
  • For Shared Secret enter the secret you set up in your Course Settings
  • Click Submit

Next you will need to establish the connection between your IMathAS course and Canvas course

• In Canvas, click one of the assessment links in your course.
• If this is your first time using this key and secret, IMathAS will ask you, the teacher, to sign into your IMathAS account. This is necessary to establish a connection between your LMS account and your IMathAS account. You will not need to do this step again, and students will not be asked to sign in and will not need a IMathAS account.
• Follow the prompts to associate the LMS course with your existing IMathAS course or create a copy.
• Once complete, all the LTI links in your LMS should work.
• Be aware:
  • Links, files, forums, and and text items were imported into your LMS. Changing them in IMathAS will not change them in your LMS
  • If you change assessment settings or the questions in an assessment in IMathAS, those changes will show up when the assessment is launched from the LMS
  • If you change due dates in IMathAS, they will be enforced by IMathAS, but the due dates in the LMS will not automatically be updated. However, there is a course setting to allow Canvas to set the due dates in IMathAS.
  • Any new items added in IMathAS, including new assessments, will not automatically show up in the LMS; you would need to repeat the export/import process.
  • If configured, grades will be sent from IMathAS to the LMS immediately every time the student completes a question, but the LMS may delay updating the grade.

Note: When configuring a course-level configuration, the use of a key in the form LTIkey_###_1 is recommended. With this type of key, students will not have or need a username for IMathAS, and they must access assignments via the LMS. This is usually desired when doing integration, and is necessary to ensure grades are passed from IMathAS back to the LMS. If, however, you are not interested in grade return, and simply want to provide single-signon from your LMS into IMathAS while allowing direct login to IMathAS as well, then you can use a key of the form LTIkey_###_0 instead. This will require students to have or create an account on IMathAS, which they'll have to log into once to establish the connection.

  • If the links are listed as Working, then you have an existing configuration, and do not need to continue.
  • For one of the links with status listed as Broken, use the drop-down menu that shows when hovering over the link name and select Edit Credentials.
  • For the Tool Provider Key, enter: LTIkey_####_1, where #### is your Course ID
  • For the Tool Provider Secret enter the secret you set up in your Course Settings
  • Check the box "Apply these credentials to all links"
  • Click Submit
• If importing a Common Cartridge, to enable grade return Blackboard requires some additional steps:
  • Return to the main course page in Blackboard.
  • For each assessment link that was imported, use the drop-down menu and select Edit
  • Set the Enable Evaluation option to Yes, specify the points possible (it does not need to match the points possible in IMathAS), and set a Due Date if desired.

Next you will need to establish the connection between your IMathAS course and BlackBoard course

• In BlackBoard, click one of the assessment links in your course.
• If this is your first time using this key and secret, IMathAS will ask you, the teacher, to sign into your IMathAS account. This is necessary to establish a connection between your LMS account and your IMathAS account. You will not need to do this step again, and students will not be asked to sign in and will not need a IMathAS account.
• Follow the prompts to associate the LMS course with your existing IMathAS course or create a copy.
• Once complete, all the LTI links in your LMS should work.
• Be aware:
  • Links, files, forums, and and text items were imported into your LMS. Changing them in IMathAS will not change them in your LMS
  • If you change assessment settings or the questions in an assessment in IMathAS, those changes will show up when the assessment is launched from the LMS
  • If you change due dates in IMathAS, they will be enforced by IMathAS, but the due dates in the LMS will not automatically be updated.
  • Any new items added in IMathAS, including new assessments, will not automatically show up in the LMS; you would need to repeat the export/import process.
  • If configured, grades will be sent from IMathAS to the LMS immediately every time the student completes a question, but the LMS may delay updating the grade.

Note: When configuring a course-level configuration, the use of a key in the form LTIkey_###_1 is recommended. With this type of key, students will not have or need a username for IMathAS, and they must access assignments via the LMS. This is usually desired when doing integration, and is necessary to ensure grades are passed from IMathAS back to the LMS. If, however, you are not interested in grade return, and simply want to provide single-signon from your LMS into IMathAS while allowing direct login to IMathAS as well, then you can use a key of the form LTIkey_###_0 instead. This will require students to have or create an account on IMathAS, which they'll have to log into once to establish the connection.

Blackboard Integration - Manual Process

To manually create a link to IMathAS, in Blackboard:

• Under the Build Content dropdown, select Web Link
• Give the link a Name
• For URL, enter https://yourIMathASsite/bltilaunch.php
• Click the checkbox for "This link is to a Tool Provider"
• If you have a global college-wide key and secret, you will not see or need to fill out the following two entries.
  • For Key, enter LTIkey_####_1, where #### is your Course ID
  • For Secret, enter the secret shown in your IMathAS Course Settings
• If you are setting up a link to an individual assessment, set "Enabled Evaluation" to Yes, and enter the points possible. Whole course links to not return grades, so there is no need to enabled evaluation for those.
• Click Submit
• If the link you just created shows "(invalid link)" next to the name, they you'll need to ask your BlackBoard administrator to approve LTI connections to IMathAS.
• Click on the link you just created.
• If this is your first time using this key and secret, IMathAS will ask you, the teacher, to sign into your IMathAS account. This is necessary to establish a connection between your LMS account and your IMathAS account. You will not need to do this step again, and students will not be asked to sign in and will not need a IMathAS account.
• If this is your first link from this course, IMathAS will ask you to select the IMathAS course you want to connect your LMS course with.
• Select the assignment you want to link with, or select "Whole Course Placement" if you want a single link to your entire IMathAS course, then click Make Placement.

Be aware assessment links created manually in this way will lose their association with IMathAS assessments when the course is copied in BlackBoard, so using the Export/Import process is recommened if you are creating individual assessment links.

LTI Integration for Other LMSs - Using Import

Go to Course Items → Export, select the items you want to export, select your LMS, and Download the Export Cartridge. The cartridge is an IMS Common Cartridge format.

Import the cartridge into your LMS. If your school has a global key and secret setup, skip ahead. Otherwise, you'll likely need to configure the LTI connection by providing the key and secret, which can be found on the Course Settings page.

Next you will need to establish the connection between your IMathAS course and LMS course

• In your LMS, click one of the assessment links in your course.
• If this is your first time using this key and secret, IMathAS will ask you, the teacher, to sign into your IMathAS account. This is necessary to establish a connection between your LMS account and your IMathAS account.

LTI Integration for Other LMSs - Manual Process

If you have a global college-wide key and secret, you do not need to set up a course-level configuration. Otherwise, you will need to set up a course-level LTI configuration. Consult your LMS's help for how to do this; some LMSs configure an LTI took at the course settings level, while some have you enter the credentials with each link.

If you need to set up a course-level LTI configuration, you will need:

• A Consumer/Tool Key: LTIkey_####_1, where #### is your Course ID
• A Secret: use the LTI secret shown in your IMathAS Course Settings
• Launch/Tool URL: https://yourIMathASsite/bltilaunch.php

The process to set up LTI links varies by LMS, so consult your LMS for details.

Be aware assessment links created manually in this way will lose their association with IMathAS assessments when the course is copied in the LMS, so using the Export/Import process is recommened if you are creating individual assessment links and your LMS supports it.

Solver Input

• Select your code from the Common Control box, then either drag-drop or copy-paste it to the box below, or
• Highlight an expression in Common Control and press Ctrl-M to update the Solver code, or
• Highlight an expression in your code before clicking Solver.
• Select an operation to perform: Solve, Differentiate, Integrate, Plot.
• You may need to change the colored Sage code below to solve for the correct variable or to adjust the plot window etc. See the help icon below for examples.

Solver: Sage Syntax

#create symbolic variables
x,y,a,b,c,d = var('x,y,a,b,c,d')
# solve the equation for x
solve( y==(a*x+b)/(c*x-d) , x )

x = var('x')
#Differentiate
diff( 3*x^4 , x )

x = var('x')
#Plot in a standard window
plot( -x^2+4 , (x,-10,10) )

x = var('x')
#Simplify
simplify( 5*x+7*(-3*x-4) )


• Declare any variables using var() as above. By default, x is a variable.
• Use two equal signs for math equations.
• With solve() diff() integral() give the independent variable after a comma.
• With plot() a range for the independent variable must be specified, e.g. (x, -10, 10).
• Select a new operation or click Go to calculate.

Solver Output

• Drag the result above to the Common Control box where you define the $answer or any other location, or
• Click Insert in Common Control to append the result to the end of the Common Control, or
• Click Insert as $answer to append $answer = result to the Common Control (not available if $answer is already defined).
• Note: Touchscreens might not be supported by the drag operation.

Number

The student is asked to enter a number (integer, decimal, or scientific notation). The answer is compared to a given tolerance. Can also accept DNE, oo (Infinity), and -oo (Negative Infinity) as answers.

Required Variables

$answer = a number or calculation resulting in a number, like $answer = 5

Defines the answer. Define multiple acceptable answers in a string separated by or: $answer = "3 or 5 or 7". Alternatively, you can provide an interval notation range of acceptable answers, like $answer = "(2,5]". Providing a range will override any tolerances set. If $answerformat is set for list answers, then this should provide a list of correct answers, like $answer = "1,2,3".

Optional Variables

$reltolerance = a decimal value

Defines the largest relative error that will be accepted. If this is not set, a relative error of .001 (.1%) is used by default.

$abstolerance = a number

Defines the largest absolute error that will be accepted. This will override the use of $reltolerance

$reqdecimals = a number

Defines the minimum decimal accuracy required (ie 2 for two decimal places). This will put a message in the answer tips stating the decimals required. If neither $abstolerance or $reltolerance is set, this will set the tolerance, otherwise the provided tolerance will be used (even if it doesn't agree with the $reqdecimal setting).

$reqdecimals = "=2" can be used to require exactly 2 decimal places in the answer, regardless of how the value rounds (so 3.5 would get marked wrong when the answer is 3.50 if "=2" is used). If you use the "=2" form, it will also round your $answer if needed for the $showanswer.
When the "=2" form is used, it overrides both $reltolerance and $abstolerance, and by default tests that the student answer exactly matches the correct answer ($abstolerance=0). To override the tolerance use +- in the setting, like this:
$reqdecimals = "=2+-.01" checks for exactly 2 decimals, but allows the answer to have an absolute error of .01
$reqdecimals = "=2+-1%" checks for exactly 2 decimals, but allows the answer to have an relative error of 1% (equivalent to $reltolerance = .01)

$reqsigfigs = a number

Defines the significant figure accuracy required. Use $reqsigfigs = 2 for at least 2 sig fig accuracy, or $reqsigfigs = "=2" to require exactly 2 sig figs in the answer, or $reqsigfigs = "[2,3]" to require 2 or 3 sigfigs. This will put also a message in the answer tips stating the significant figures required. If you use the "=2" form, it will also round your $answer if needed for the $showanswer.
This setting overrides both $reltolerance and $abstolerance, and by default tests that the student answer rounded to the specified sigfigs matches the correct answer. To override the tolerance use +- in the setting, like this:
$reqsigfigs = "=2+-.01" checks for exactly 2 sigfigs, but allows the answer to have an absolute error of .01
$reqsigfigs = "=2+-1%" checks for exactly 2 sigfigs, but allows the answer to have an relative error of 1% (equivalent to $reltolerance = .01)

$answerformat = "list", "exactlist", "orderedlist", "set", "integer, "units", "nosoln", or "nosolninf"

• Answerformats can be combined, like $answerformat = "nosoln,list"
• $answerformat = "list", "exactlist", or "orderedlist" specifies that a list of answers is expected.
• If $answerformat="list", then duplicate values are ignored.
• If $answerformat="exactlist", then duplicate values are not ignored.
• If $answerformat="orderedlist", the list must be in the same order and contain identical counts of values.
• $answerformat = "set" behaves like "list", but expects the answer list to be wrapped in curly braces as a set.
• $answerformat = "integer" changes the entry hint to only indicate integers, and rejects answers that contain decimals (except it does allow 2.0 instead of 2)
• $answerformat = "units" adds unit checking. Supply the answer like $answer = "3 kg/m^2". The student's answer can be in other equivalent units, so "300 cm" is considered equivalent to "3 m". The answer must be in the format [decimal number]*[unit]^[power]*[unit]^[power].../[unit]^[power]*[unit]^[power]..., though multiplication can be implied. Also, 'per' may be used for division of units, and 'unit squared', 'square unit', 'unit cubed' and 'cubic unit' may be used. Note that the units do not require mathematically-proper parens around the denominator. The decimal number can include basic scientific notation in 3E5 or 3*10^5 formats. Examples: 4 cm, and 3.5E4 feet per second squared Note that tolerances are scaled to the unit, so $answer = "3m" with $abstolerance = .1 would mean .1 meters, so "310cm" would still be within tolerance. If $reqsigfigs is set, the specified number of sigfigs will need to be present in the student's answer, regardless of units.
• $answerformat = "nosoln" or "nosolninf" adds a list radio buttons for "no solutions" and optionally "infinite solutions". $ansprompt can override the default statements like this: $ansprompt = "One value, x=;No values;Many values"

$partialcredit = array(number,score,[number,score,...])

Allows you to specify partial credit for other answers. The array should be given in the form array(number,score,number,score,...), where number is the value to compare to the student answer, and score is a proportion between 0 and 1 to award as partial credit. Note this currently only works for single number answers; "or" and list answers are not supported.

$ansprompt = string

A string that will be displayed in front of the input box. Example: $ansprompt="y="

$displayformat = "alignright"

Aligns the text in the answer box to the right side

$answerboxsize = number

Determines the number of characters space provided for entry of an answer. Defaults to 20.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the question input box in that location

$showanswer

The answer to show to students (if option if available). Defaults to $answer. Use this to give a detailed answer, or a rounded off answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Calculated

A student is asked to enter a number or a calculation, like 2/3, 5^2, or sin(2). Can also accept DNE, oo (Infinity), and -oo (Negative Infinity) as answers.

Required Variables

$answer = a number or calculation resulting in a number

Defines the answer. Define multiple acceptable answers in a string separated by or: $answer = "3 or 5 or 7". Alternatively, you can provide an interval notation range of acceptable answers, like $answer = "(2,5]". Providing a range will override any tolerances set

To have the answer display as a rendered expression, provide the answer as a string. For example, if you want the answer to show as 2⁴ then you'd specify $answer = "2^4". If you specified $answer = 2^4, the answer would display as 16.

Optional Variables

$answerformat = "fraction", or one of the other options below.

Specifies answer format options. Some can be combined in a list, like this: $answerformat="nodecimal,notrig".

• Base format types: only use at most one of these at a time
  • fraction: requires the answer to be a single fraction (like 10/6, 1/3, or 5)
  • reducedfraction: a reduced fraction (like 5/3 or 5)
  • mixednumber: a reduced mixed number (like 2 1/2 or 2_1/2, or 2/3 or 5)
  • mixednumberorimproper: a reduced mixed number or improper fraction (like 2 1/2 or 5/2)
  • sloppymixednumber: a mixed number (will take 5/2, 2 1/2, even 1 3/2)
  • scinot: scientific notation (like 2.3*10^4)
  • scinotordec: scientific notation (like 2.3*10^4) or decimal value
  • fracordec: a single fraction or decimal value. Can be combined with "allowmixed" to also allow mixed numbers.
  • decimal: requires the answer to be an integer or decimal value
• Mix-ins: You can add these as needed to modify what's allowed
  • allowunreduced: can be combined with "mixednumber" or "mixednumberorimproper" to allow unreduced fractional parts
  • allowxtimes: allows the use of x for multiplication (like 23x10^2 for 23*10^2), typically in combo with the "scinot" format
  • allowplusminus: allow use of +- in the answer. Will enable the 'list' option if not already included.
  • nodecimal: require an answer without decimals (also disallows 10^-2 and 3E-2)
  • notrig: require an answer without trig functions (sin,cos,tan,sec,csc,cot)
  • allowmixed: will enable support for mixed numbers (like 2 1/2) in answers
  • allowdegrees: will enable the use of the degree symbol to designate degrees, so sin(30degree)=1/2.
  • noval: tells the answer preview to not compute a decimal equivalent (deprecated - this option is now enabled by default)
  • showval: tells the answer preview to display a decimal equivalent
  • sameform: requires the student's answer be in the "same form" as the correct answer. This means exactly the same, except for commutation of addition and multiplication, multiplication by 1, implicit multiplication, and extra parentheses. Use with caution.
• List options: only use at most one of these at a time
  • list: a list of answers is expected - ignores duplicate values (1,1,2 is equivalent to 1,2)
  • exactlist: a list of answers is expected - does not ignore duplicates
  • orderedlist: a list of answers is expected - order is important, and duplicates are not ignored
• Special options:
  • nosoln: adds radio buttons for "no solutions". Use $answer="DNE" if the answer is no solutions.
  • nosolninf: adds radio buttons for "no solutions" and "infinite solutions". Use $answer="DNE" or $answer="oo" respectively if needed.
  • To override the default "no solutions" and "infinite solutions" wording, you can define $ansprompt as a list of semicolon-delimited strings to override the default wording. For example,
    $ansprompt = "One value, x=;No values;Many values"

$formatfeedbackon = true

Turns on "right answer, wrong format" feedback on the question

$reltolerance = a decimal value

Defines the largest relative error that will be accepted. If this is not set, a relative error of .001 (.1%) is used by default.

$abstolerance = a number

Defines the largest absolute error that will be accepted. This will override the use of $reltolerance

$reqdecimals = a number

Defines the decimal accuracy required (ie 2 for two decimal places). This will put a message in the answer tips stating the decimals required. If neither $abstolerance or $reltolerance is set, this will set the tolerance, otherwise the provided tolerance will be used (even if it doesn't agree with the $reqdecimal setting).

$reqsigfigs = a number

Defines the significant figure accuracy required. Only valid for "decimal", "scinot", and "scinotordec" $answerformat options. Use $reqsigfigs = 2 for at least 2 sig fig accuracy, or $reqsigfigs = "=2" to require exactly 2 sig figs in the answer, or $reqsigfigs = "[2,3]" to require 2 or 3 sigfigs. This will put also a message in the answer tips stating the significant figures required. If you use the "=2" form, it will also round your $answer if needed for the $showanswer.
This setting overrides both $reltolerance and $abstolerance, and by default tests that the student answer rounded to the specified sigfigs matches the correct answer. To override the tolerance use +- in the setting, like this:
$reqsigfigs = "=2+-.01" checks for exactly 2 sigfigs, but allows the answer to have an absolute error of .01
$reqsigfigs = "=2+-1%" checks for exactly 2 sigfigs, but allows the answer to have an relative error of 1% (equivalent to $reltolerance = .01)

$requiretimes = a list, like "^,=3,cos,<2"

Adds format checking to the student's answer. The list can include multiple checks, which come in pairs. The first is the symbol to look for. The second describes what is acceptable. For example, in the string shown above, the symbol "^" would be required to show up exactly 3 times, and "cos" would be required to show up less than 2 times.
Be aware that if you search for "5,=1", it will match both 5 and 15 and 2.5, since all three strings contain a 5. When searching for numbers, you can avoid this by putting a "#" before the number, like "#5,=1", which would match the 5 but not 15 or 0.5. Beware this type of search ignores signs.
You can use just "#" in the symbol location to match any number (including decimal values); 3.2^5 would match twice.
You can match either of two symbols by putting || between them, like ".5||1/2,>0"
You can use a regular expression by putting in the symbol location "regex:expression"
You can put "ignore_commas,true" at the beginning of the $requiretimes to ignore commas in the answer
You can put "ignore_spaces,true" at the beginning of the $requiretimes to ignore spaces in the answer
You can put "ignore_symbol,$" (or some symbol other than $) at the beginning of the $requiretimes to ignore that symbol in the answer

$requiretimeslistpart = a list, in the same format as $requiretimes

Similar to $requiretimes, but this check is applied to each element of the answer list when a list $answerformat is used, where $requiretimes would be applied to the entire list of answers. To apply different $requiretimes to each element of the $answer list, separate them with semicolons, like "pi,=1;/,=1;;"

$ansprompt = string

A string that will be displayed in front of the input box. Example: $ansprompt="y="

$answerboxsize = number

Determines the number of characters space provided for entry of an answer. Defaults to 20.

$hidepreview = true

Hides the Preview button. Could be useful in multipart questions, or if you're only asking for a simple response, like a fraction

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the question input box in that location

$showanswer

The answer to show to students (if option if available). Defaults to $answer. Use this to give a detailed answer, or a rounded off answer.

$previewloc (In Question Text)

Where you want the preview button to be located. Defaults to after the entry box if not placed in question text.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Multiple-Choice

Required Variables

$questions (or $choices) = an array of choices

Defines the choices. If you use $choices, don't define $questions

$answer = the index into $questions that contains the correct answer

Defines the answer. Remember that arrays are zero-indexed, so if $questions = array("correct","wrong","wrong"), then $answer=0. Define multiple acceptable answer indices in a string separated by or: $answer = "0 or 1".

Optional Variables

$displayformat = "horiz", "select", "2column, "3column", or "inline"

Will lay out the choices horizontally, as a select box, in multiple columns, or inline with text rather than using the default vertical layout

$noshuffle = "all" or "last" or "last2"

If $noshuffle="all", then the $questions array will not be randomized (shuffled). If $noshuffle = "last", then the $questions array will be randomized, except for the last element. This is for options like "None of the above". You can use "last2" or "last3" to randomize all but the last 2 or 3 elements.

$partialcredit = array(index,score,[index,score,...])

Allows you to specify partial credit for other answers. The array should be given in the form array(index,score,index,score,...), where index is the index in $questions, and score is a proportion between 0 and 1 to award as partial credit. For example, if $answer = 0 and $partialcredit = array(2,.3), then the student would get full credit for selecting the item corresponding with $questions[0], and 30% credit for selecting the item corresponding with $questions[2]. All other answers would receive 0 credit.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$ansprompt = string

When $displayformat = "select" is used, this allows you to override the default "Select an answer" text that displays. Do not use this unless there's a really strong reason to.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the choice list in that location

$showanswer

The answer to show to students (if option if available). Defaults to the text of the correct answer. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Multiple-Answer

Required Variables

$questions (or $choices)= an array of questions

Defines the choices. If you use $choices, don't define $questions

$answers = a list of the indexes into $questions that contain the correct answer

Defines the answers. Remember that arrays are zero-indexed, if $questions = array("correct","correct","wrong"), then $answers="0,1". Or there are more than one correct combination, separate with or, like $answers = "0,1 or 0,3"

Optional Variables

$scoremethod = "answers" or "allornothing" or "takeanything"

By default, the total points possible are divided by the number of questions, and partial credit is lost for each correct answer missed and each wrong answer selected. If $scoremethod="answers" is set, then the total points possible are divided by the number of answers (tougher grading scheme). If $scoremethod="allornothing", then the student will only get credit if every piece is correct (no partial credit). if $scoremethod="takeanything", full credit will be given for any response.

$displayformat = "horiz", "2column, "3column", or "inline"

Will lay out the choices horizontally, in multiple columns, or inline with text rather than using the default vertical layout

$noshuffle = "all" or "last"

If $noshuffle="all", then the $questions array will not be randomized (shuffled). If $noshuffle="last", then the last element of $questions will not be randomized (shuffled) but the others will.

$answerformat = "addnone"

Adds "None of these" to the options. This is added automatically if $answers="", and you can add "None of these" yourselv to $questions, but this provides another way to always include the "None of these" option.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the choice list in that location

$showanswer

The answer to show to students (if option if available). Defaults to the text of the correct answers. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Matching

Required Variables

$questions = an array of questions

Defines the questions - these will be on the left with entry boxes

$answers = an array of answers

Defines the answers - these will be on the right and lettered

Optional Variables

$matchlist = a list of the indexes into $answers that contain the match to each question.

Defines correct matches. By default, it is assumed that each element of $questions is matched one-to-one with the corresponding element of $answers (in other words, that $answers[0] is the answer to $questions[0]).
$matchlist allows you to define one-to-many matches. Example: if $questions=array("cat","dog","quartz") and $answers=array("animal","mineral"), then $matchlist = "0,0,1"

$questiontitle = string

Displays a title above the list of questions. For example, if $questions was a list of states, then $questiontitle="States" would be appropriate

$answertitle = string

Displays a title above the list of answers

$noshuffle = "questions" or "answers"

Retains original order of questions or answers, and only shuffles the other. By default, both lists are shuffled

$displayformat = "select" or "2columnselect"

Only displays the $questions, with select boxes next to each containing the $answers. This should only be used with pure text $answers.

$scoremethod = "allornothing"

Setting "allornothing" will mean no partial credit is given, and the student must match all parts correctly to get credit.

$ansprompt = string

This allows you to override the default "-" that displays in the dropdowns when no selection has been made, for example to replace it with "?". It's recommended to not use this unless there's a really strong reason to.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place matching questions and answers in that location

$showanswer

The answer to show to students (if option if available). Defaults to the list of correct matches. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Function

Required Variables

$answer = string

Defines the answer function, entered as a string. For example, $answer="2sin(x)". You can specify multiple acceptable answers by separating with "or", like $answer="x^2 or x^4"
Note: The system will accept any algebraically equivalent answer. To only allow answers of a specific format, you'll also need to define $requiretimes (see below).

Optional Variables

$variables = string

A list of all variables in the function (including letters representing constants). Defaults to "x". Can use "f()" to indicate a symbol represents a function.

$domain = "inputmin,inputmax"

Defines the domain on which to compare the given answer and correct answer functions. The same domain applies to all variables. An option third list element "integers" can be given, which limits the domain to integer values. The domain defaults to real numbers from -10 to 10. If using multiple variables, can extend domain to define domain for each variable separately. Example: $variables = "x,y"; $domain = "0,5,20,25"

$requiretimes = a list, like "^,=3,cos,<2"

Adds format checking to the student's answer. The list can include multiple checks, which come in pairs. The first is the symbol to look for. The second describes what is acceptable. For example, in the string shown above, the symbol "^" would be required to show up exactly 3 times, and "cos" would be required to show up less than 2 times. You can use "#" in the symbol location to match any number (including decimal values); 3.2x+42y would match twice.
You can use a regular expression by putting in the symbol location "regex:expression"
You can match either of two symbols by putting || between them, like "x^-3||/x^3,>0"
Include "ignore_case,false" to make the search case sensitive.
You can put "ignore_spaces,true" at the beginning of the $requiretimes to ignore spaces in the answer
Include "ignore_symbol,$" (or some symbol other than $) at the beginning of the $requiretimes to ignore that symbol in the answer
Note that commas are ignored by default with Function type, and a basic exponent like x^(-3) is converted to x^-3 before the check.

$answerformat = "equation" or "inequality" or "generalcomplex" or "toconst" or "scalarmult" or "nosoln" or "nosolninf" or "sameform" or "list" (can combine, like "equation,nosoln")

By default, the student answer is expected to be an expression, and be equivalent (at points) to the specified answer. This option changes this behavior.
"equation": Specifies that the answer expected is an equation rather than an expression. The given answer should also be an equation. Be sure to specify all variables in the equation in $variables. This may fail on equations that are near zero for most values of the input; this can often be overcome by changing the $domain
"inequality": Specifies that the answer is expected to be an inequality rather than an expression. The given answers should also be an inequality. Be sure to specify all variables in the equation in $variables. This may fail on equations that are near zero for most values of the input; this can often be overcome by changing the $domain
"generalcomplex": Specifies the answer is a complex function, involving i.
"list": Allow a list of expressions or equations to be entered. Does not ignore duplicates. You cannot use this in combination with $partialcredit. $requiretimes will apply to each element of the list.
"toconst": Specifies that the answer provided by the student is allowed to differ from the specified answer by a constant for all inputs. Appropriate for comparing antiderivatives. This may fail on expressions that evaluate to very large values or raise numbers to very large powers.
"scalarmult": Specifies that the answer provided by the student is allowed to differ from the specified answer by a scalar multiple.
"allowplusminus": allow use of +- in the answer. Will enable the 'list' option if not already included.
"nosoln" or "nosolninf" adds a list radio buttons for "no solutions" and optionally "infinite solutions". $ansprompt can override the default statements like this: $ansprompt = "One function, f(x)=;No such function exists"
"sameform": requires the student's answer be in the "same form" as the correct answer. This means exactly the same, except for commutation of addition and multiplication, multiplication by 1, implicit multiplication, and extra parentheses. (2x-3)(5-x) would be "sameform" as (-1x+5)(2*x-3), but 2/4x and 1/2x and 0.5x would not be "sameform". Use with caution.

$partialcredit = array(string,score,[string,score,...])

Allows you to specify partial credit for other answers. The array should be given in the form array(string,score,string,score,...), where string is the expression to compare to the student answer, and score is a proportion between 0 and 1 to award as partial credit. Note this currently only works for single expression answers; "or" answers are not supported.

$formatfeedbackon = true

Turns on "right answer, wrong format" feedback on the question

$reltolerance = a decimal value

Defines the largest relative error that will be accepted. If this is not set, a relative error of .001 (.1%) is used by default.

$abstolerance = a number

Defines the largest absolute error that will be accepted. This will override the use of $reltolerance

$ansprompt = string

A string that will be displayed in front of the input box. Example: $ansprompt="y="

$answerboxsize = number

Determines the number of characters space provided for entry of an answer. Defaults to 20.

$previewloc (In Question Text)

Where you want the preview button to be located. Defaults to after the entry box if not placed in question text.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

String

Required Variables

$answer = a string

Defines the answer. Multiple acceptable answers can be entered using "or". Example: $answer = "dog or cat"

Optional Variables

$strflags = string of flags, like "ignore_case=1,trim_whitespace=0"

Determines how the string will be compared. Set to 1 to turn on, 0 for off. Flags are:

• ignore_case: ignores capitol/lowercase differences
• trim_whitespace: trims leading and ending whitespace (spaces)
• compress_whitespace: compresses multiple spaces to one space and trims
• remove_whitespace: removes all whitespace (spaces)
• ignore_order: treats ABC and CBA as equivalent
• ignore_commas: removes commas
• partial_credit: awards partial credit based on Levenshtein distance between strings
• all_words: gives credit the student answer contains a list of key words. $answer should provide a comma-separated list of words to look for, and partial credit will be given for each word found. Cannot be combined with $answerformat="list" or $partialcredit.
• allow_diff=n: gives full credit for answers with Levenshtein distance between strings ≤ n
• in_answer: gives credit if $answer is contained anywhere in the student answer
• regex: interprets $answer as a regular expression (pattern) to evaluate the student's answer. For example, $answer="cost.*increas" will give credit if the word cost appears before increas in the student's answer. $answer="increas|ris" will accept any of the following: increasing, increases, rising, or risen etc.
• special_or: use *or* for separating answers rather than or.
• ignore_symbol=sym: Unlike the other flags, this is not an on/off flag. Set this equal to a symbol to ignore that symbol in student answers. This flag can be used multiple times with different symbols.

By default, compress_whitespace and ignore_case are On. Only one of partial_credit, allow_diff, in_answer or regex may be used at a time.

$scoremethod = "takeanything" or "takeanythingorblank" or "submitblank"

"takeanything" or "takeanythingorblank" sets the problem to give full credit for any answer. "takeanythingorblank" also counts blank answers as correct. "submitblank" will cause blank answers to get submitted for scoring (new system only).

$answerformat = "list" or "logic" or "setexp"

"list" specifies that a list of answers is expected. Renders ignore_commas unnecessary. Cannot be used with partial_credit flag. Duplicates are not ignored.

"logic" enables a separate grading algorithm for logic statements, ignoring $strflags. The $answer should be given using vv for or, ^^ for and, neg for not, xor for exclusive or, => for conditional, and <=> for biconditional. Parens are supported, but no other symbols. The variables used in the logic expression must be declared by defining $variables.

"setexp" enables a separate grading algorithm for set expression statements, ignoring $strflags. The $answer should be given using 'nn' for intersection, 'uu' for union, '-' for set difference, '^c' for set complement, and 'oplus' for symmetric difference.

$partialcredit = array(string,score,[string,score,...])

Allows you to specify partial credit for other answers. The array should be given in the form array(string,score,string,score,...), where string is the value to compare to the student answer, and score is a proportion between 0 and 1 to award as partial credit. Note this only works for single string answers; list answers and "all_words" are not supported.

$ansprompt = string

$displayformat = "usepreview" or "typeahead" or "usepreviewnomq"

"usepreview" enables mathquill entry for mathematical answers.
"usepreviewnomq" adds a preview button for previewing mathematical answers in asciimath.
"typeahead" will enable an auto-suggest list of options once the student has typed at least two letters of the word. Provide the auto-suggest list in the variable $questions.

$variables

When $answerformat="logic" or "setexp" is used, define the $variables in the logic statement, like "p,q"

$requiretimes = a list, like "^,=3,cos,<2"

Adds format checking to the student's answer. Usually not needed for string questions, but can be useful when the "logic" or "setexp" answerformat is used. The list can include multiple checks, which come in pairs. The first is the symbol to look for. The second describes what is acceptable. For example, in the string shown above, the symbol "^" would be required to show up exactly 3 times, and "cos" would be required to show up less than 2 times.

$ansprompt = string

A string that will be displayed in front of the input box. Example: $ansprompt="type: "

$answerboxsize = number

Determines the number of characters space provided for entry of an answer. Defaults to 20.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the answer entry box in that location

$showanswer

The answer to show to students (if option if available). Defaults to the text of the correct answer. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Essay

Required Variables

None - the essay type is not computer graded.

Optional Variables

$answerboxsize = "rows" or $answerboxsize = "rows,columns"

Determines size of space provided for entry of an answer. Defaults to 5 rows, 50 columns.

$displayformat = "editor" or "editornopaste" or "pre"

"editor" to use the rich text editor for the essay answer box, or "editornopaste" for the rich text editor with paste disabled.
"pre" to use standard text entry, and to display in gradebook as preformatted text.

$scoremethod = "takeanything" or "takeanythingorblank" or "nomanual"

The first two sets the problem to give full credit for any answer. The second also counts blank answers as correct. The "nomanual" option will give no credit for any answer, but doesn't mark the question as needing manual grading.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the essay box in that location

$showanswer

The answer to show to students (if option if available). Defaults to the text of the correct answer. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

Drawing

Drawing questions require the student to draw one or more lines/curves or dots. Dots are graded right/wrong. Lines/curves are graded based on the deviation of the drawn line from the correct line.

Required Variables

$answers = a string or array of strings describing the points or curves to be drawn

Curves: "f(x)" like "x^2+3".
Line segments or rays: "f(x),xmin,xmax", like "x+1,-3,2" or "x+1,-oo,3"
Dots: "x,y" for closed dots, "x,y,open" for open dots, like "2,3"
See below for additional entry formats for other curves when using "twopoint" drawing.
When using twopoint drawing, you can preface an answer with "optional", like "optional,2,3", to indicate that drawing element is not required, but shouldn't mark down the score if present.

Recommended Variables

$answerformat = "twopoint", "polygon", "inequality", "numberline", "freehand", or (for the older tools), "line,lineseg,dot,opendot"

Limits the drawing tools available to students. Defaults to the older drawing tools "line,dot,opendot".

$answerformat="twopoint" will use a different set of drawing tools for specific shapes that all use two control points to define the shape. It is strongly recommended you use these instead of the older tools.

• $answerformat="twopoint" will use a default tool set of line, parabola, absolute value, circle, and dot tools
• You can limit or expand the tools by specifying them: e.g. $answerformat = "twopoint,line,parab". Valid values are:
  • line (lines)
  • lineseg (line segment)
  • ray (rays)
  • parab (vertical parabolas)
  • horizparab (horizontal parabolas)
  • halfparab (half a vertical parabola)
  • cubic (a(x-h)^3+k style cubics)
  • abs (absolute value)
  • circle (circles)
  • dot (closed dots)
  • opendot (open dots)
  • sqrt (square root)

  • genlog (logarithm with any vertical asymptote)
  • rational (linear/linear rational)
  • ellipse (ellipses)
  • hyperbola (vertical or horizontal hyperbolas)
• For lines, vertical parabolas, absolute values, square roots, cubics, cuberoots, sines, cosines, exponentials, logs, and rationals (linear/linear only) give $answers as a function of x, like "2(x-1)^2+3"
• For line segments and rays, given $answers as a function with domain, like "2x+4,-oo,3", or for vertical line segments use x= and give the range, like "x=4,-2,3"
• For dots give $answers as "x,y", or "x,y,open" for open dots
• For circles, give $answers as "circle,x,y,radius", like "circle,2,-1,3"
• For ellipses, give $answers as "ellipse,x,y,x_radius,y_radius", like "ellipse,1,2,4,2"
• For hyperbolas of form (x-h)^2/a^2-(y-k)^2/b^2=1, give $answers as "horizhyperbola,h,k,a,b"
• For hyperbolas of form (y-k)^2/a^2-(x-h)^2/b^2=1, give $answers as "verthyperbola,h,k,a,b"
• For horizontal parabolas give $answers as "x=equation", like "x=2(y-1)^2-3".
• For half parabolas give $answers as "equation,>xvertex", like "(x-1)^2-3,>1". Note only half parabolas are supported, not arbitrary segments.
• For vertical lines give $answers as "x=number", like "x=3".
• For vectors, give $answers as "vector, x_start, y_start, x_end, y_end" for position vectors, or "vector, dx, dy" for displacement vectors. Note you can use $scoremethod to change how vectors are scored.

$answerformat = "polygon" can be used for drawing a single polygon; give $answer as array of points in order joined with edges.

$answerformat = "closedpolygon" can be used for drawing a single polygon that is closed; the enclosed area will be shaded and the drawing terminate when the shape is closed. The format is the same as "polygon", except make sure the first and last entry of your $answers array are identical.

$answerformat="inequality" will use a set of drawing tools for graphing linear inequalities in two variables. Give $answers for non-vertical lines in form like ">=3x+4", "<5x+4", and "x<=3" for vertical lines.

$answerformat="inequality,parab" will use a set of drawing tools for graphing quadratic inequalities in two variables. Give $answers in form like ">=x^2-4", "<x^2+1". Use $answerformat="inequality,both" to turn on lines and parabolas.

$answerformat="inequality,abs" will use a set of drawing tools for graphing absolute value inequalities in two variables. Give $answers in form like ">=abs(x-3)+4", "<3abs(x)". Use $answerformat="inequality,line,abs,parab" or some combo to turn on multiple tools.

$answerformat="numberline" will use a set of drawing tools for graphing inequalities or points in one variable on a number line. Give $answers as dots and line segments, or use the intervalstodraw function from the interval macro library to form the $answers array.

$answerformat="freehand" will allow freehand drawing without any drawing tools. This mode can NOT be autograded, and should only be used for manually graded answers.

$answerformat can also be used to limit the older tools: $answerformat = "line", or $answerformat = "line,dot"

$snaptogrid = spacing

Turns on snapping, where points will jump to a grid. $snaptogrid = 1 will jump to the nearest integer. $snaptogrid = 0.5 will jump to the nearest .5. $snaptogrid = "2:4" will jump to the nearest 2 in the x and 4 in the y. Does not have to match the actual grid line spacing. Be aware that due to pixelation, the snapping may not land on exact values correctly. This is usually corrected for automatically, but it sometimes fails if the correction would be too large. In that case, use the getsnapwidthheight macro to compute an imagewidth and imageheight that will be pixel accurate.

Optional Variables

$grid = "xmin,xmax,ymin,ymax,xscl,yscl,imagewidth,imageheight"

Defines the grid to be drawn on. Defaults to "-5,5,-5,5,1,1,300,300". You can set all or just some of the values. For example, to just set the window, you could use "0,10,0,10"
If using $answerformat="numberline", set ymin and ymax to 0.
If desired, you can set separate label and grid spacing using "xmin,xmax,ymin,ymax,xlabelspacing:xgridspacing,ylabelspacing:ygridspacing,imagewidth,imageheight". You can specify axis labels using "xmin,xmax,ymin,ymax,xlabelspacing:xgridspacing:xaxislabel,ylabelspacing:ygridspacing:yaxislabel,imagewidth,imageheight". To create first quadrant graphs, use "0:-n" (for some value of n) for xmin and/or ymin to only have gridlines and labels after 0, while still using -n to adjust spacing.

$background = equation or array of equations, using the showplot macro format

Define a graph to display in the background, to be drawn on top of. Example: $background = "x^2,red".
You can also set $background a string of asciisvg commands prefaced with "draw:", like "draw:line([1,1],[3,3]);". Note that initPicture and axes will already have been called, so do not include them.
You can also set $background to "none" to remove axes and the grid.

$partweights = array or list of weights

Defines grading weight for each line or dot in $answers. Example: $partweights = ".5,.25,.25". Defaults to equal weights on each line or dot.

$reltolerance = tolerance scaling factor

Scales the grading tolerance. Defaults to 1. Set $reltolerance = 2 to make the grading twice as tolerant; $reltolerance = 0.5 to make grading half as forgiving

$abstolerance = grading cutoff

Sets all-or-nothing grading. If score < $abstolerance, the student receives 0 for the question (note: score is between 0 and 1). Otherwise the student will receive full credit. Not set by default.

$scoremethod = "takeanything", "direction", "relativelength", "ignoreoverlap"

When "takeanything" is used, this will give full credit for any non-blank answer. This might be of use with the freehand drawing option.
"direction" and "relativelength" are only used for vectors. "direction" will score the initial point and direction for position vectors, but not length, and will only score direction for displacement vectors. "relativelength" will score like "direction", but will also check that the drawn vectors have correct lengths relative to each other.
"ignoreoverlap" only works with $answerformat="line", and will not deduct for overlapped lines.

$readerlabel = string

A string that will be used as a visually hidden label on the input box for screenreaders.

$answerbox (In Question Text)

Using the variable $answerbox in the Question Text will place the question input drawing tool in that location

$showanswer

The answer to show to students (if option if available). Defaults to the text of the correct answer. Use this to substitute a detailed answer.

$hidetips = true

Hides the question entry tips that display by default. This should only be used when a question type is being used in an unintentional way, or if the question type gives away critical info to the student.

N-Tuple

N-Tuple questions require the student to enter an n-tuple or list of n-tuples. This can be used for coordinate points, vectors, or any other n-tuple of numbers.

Required Variables

$answer = a string containing an n-tuple or list of n-tuples

Defines the answer n-tuple or list of n-tuples. N-tuples can be any dimension, but must be surrounded by any of: (), [], {}, <>. Examples: $answer = "(1,2)", $answer = "<2,3,4>,<1,5,7>", $answer = "(1,2) or (1,3)"

Optional Variables

$displayformat = "point", "pointlist", "vector", "vectorlist", "list", "set", "setlist"

Changes the answer entry tips (does NOT change how the question is graded). For points, entry like (2,3) is specified. For vectors, entry like <2,3> is specified.

$answerformat = "scalarmult", "anyorder", "nosoln", "nosolninf"

"scalarmult" will accept any answer that is a scalar multiple of the correct answer.
"anyorder" will accept elements in any order, so (2,1) would be treated equivalent to (1,2)
$answerformat = "nosoln" or "nosolninf" adds a list radio buttons for "no solutions" and optionally "infinite solutions". $ansprompt can override the default statements like this: $ansprompt = "One value, x=;No values;Many values"

$scoremethod = "byelement"

By default, the whole n-tuple must be correct to receive any credit. Set $scoremethod = "byelement" to give partial credit if only some elements of the n-tuple are correct.

$partweights = ".2,.8"

Can be used with $scoremethod = "byelement" to change the value of each part of the ntuple

$reltolerance = a decimal value

Defines the largest relative error that will be accepted. If this is not set, a relative error of .001 (.1%) is used by default.

Calculated N-Tuple

Calculated N-Tuple questions require the student to enter an n-tuple or list of n-tuples. This can be used for coordinate points, vectors, or any other n-tuple of numbers. This is identical the the N-tuple answer type, but allows students to enter mathematical expressions rather than just numbers, such as (5/3, 2/3).

Required Variables

$answer = a string containing an n-tuple or list of n-tuples

• Multiple Choice: "choices"
• Multiple Answer: "multans"
• Matching: "matching"
• Function/expression: "numfunc"
• Drawing: "draw"
• N-tuple: "ntuple"
• Calculated N-tuple: "calcntuple"
• Matrix: "matrix"
• Calculated Matrix: "calcmatrix"
• Complex: "complex"
• Calculated Complex: "calccomplex"
• Interval: "interval"
• Calculated Interval: "calcinterval"
• Chemical Equation: "chemeqn"
• Chemical Molecule Drawing: "molecule"
• Essay: "essay"
• File Upload: "file"
• String: "string"

Question part variables

For each question part, you will need to define the variables (like $answer, $questions, etc.) you would normally need to define. However, you will need to suffix the variable with a part designator. For example, based on $anstypes above, the first answer is a number. Instead of $answer = 5, enter $answer[0] = 5. This designates that this answer belongs to the first element of $anstypes. Likewise, to set the variables for the "numfunc" type, you'd set $variables[5] = "x".

$answerbox[partnum] (In Question Text)

The array $answerbox will contain the entry boxes for each answer type. In the question text, you will need to position these boxes within the question. For example: "Enter a number: $answerbox[0]. Now a function: $answerbox[1]". Alternatively, you can use [AB#]: "Enter a number: [AB0]. Now a function: [AB1]"

Optional Variables

$answeights = an array or list of weights for each question

By default the points for a problem are divided evenly over the parts. Use this option if you wish to weight parts differently. Example: $answeights = array(.2,.3,.5). Best practice is to use percents, but if other values are used, they will be converted to percents.

$scoremethod = "singlescore" or "allornothing"

Instead of recording individual scores for each question part, these will cause a single score to be recorded for the question. "singlescore" totals the individual part scores, while "allornothing" will only give full credit or no credit. If you need to specify per-part indexed scoremethod values as well, you can define this as the array value $scoremethod['whole'] instead.

Question part options

You can define any optional variable for each question part. Like above, suffix the variable with the part designator.

$showanswer

You can either define $showanswer for individual question parts (ie, $showanswer[1]="`x^2`"), or you can set one $showanswer, which will be the only answer shown for the problem (ie, $showanswer = "x=$answer[0], y=$answer[1]")

$showanswerloc (In Question Text)

Optionally, you can use $showanswerloc to place a single $showanswer "Show Answer" button, or $showanswerloc[part] to place "Show Answer" buttons for each part. You can also use short tags of the form [SAB] or [SABn] (like [SAB2]). Note that if you use this to place one Show Answer button, you must place all of them, or else the remainder will not show. Use $showanswerstyle = 'inline' to allow Show Answer to be placed inline with text rather than on its own line.

Scaffolding

Scaffolded questions, also know as Sequential Multipart questions, allow you to break a question up into chunks, where the second chunk only shows after the first chunk is correctly answered or the student runs out of tries. This allows you to use the answer to the first chunk in the second without "giving away" the answer, and allows a student who gets stuck on the first chunk to move on to the rest of the question.

Note: scaffolding is only available in the new assessment interface. If you are using the old interface, the question will behave like a regular multipart question.

Scaffolded questions are an extension of Multipart questions. To turn a multipart question into a scaffolded question, just add an isolated line with three or more slashes in the Question Text where you want the chunks broken apart.

An example: (in the Question Text)

To simplify $a(x+$b) + $c, first we need to distribute:

$a(x+$b) = $answerbox[0]

///

Next, combine like terms:

$a x + $ab + $c = $answerbox[1]

Conditional

Required Variables

$anstypes = an array or list of answer types

Defines the answer type for each part. Example: $anstypes = "number,number". See the Multipart help above for the list of short names

$answer = any of these:

• A boolean (true/false) expression: Something that evaluates to true or false.
  Example: $answer = ($a>3)
  Example: $answer = comparefunctions($f,'x^2') && ($a!=0)
• A single numerical value in the interval [0,1]: will award that percentage of the total possible points.
• array('function',$a,$b): Will compare the functions $a and $b and mark the question correct if they are equivalent. Can set $variables, $reltolerance, $abstolerance, and $domain as needed, like with Function type questions
• array('number',$a,$b): Will compare the numbers or numerical expressions $a and $b and mark the question correct if they are equivalent. Can set $reltolerance or $abstolerance as needed, like with Number/Calculated type questions
• Multiple comparisons: You can mix the two types above by creating an array of comparisons. All must be true for the question to be marked correct.
  Example: $answer = array($a>3, array('function',$b,c), array('number',evalfunc($b,$a),5))

Question part variables

For each question part, you will need to define the variables (like $questions, etc.) you would normally need to define, except you should not define an $answer. However, you will need to suffix the variable with a part designator. For example, based on $anstypes above, the first answer is a number. Instead of $displayformat = "select", enter $displayformat[0] = "select". This designates that this setting belongs to the first element of $anstypes.

$answerbox[partnum] (In Question Text)

The array $answerbox will contain the entry boxes for each answer type. In the question text, you will need to position these boxes within the question. For example: "Enter a number: $answerbox[0]. Now a function: $answerbox[5]"

Optional Variables

Question part options

You can define any optional variable for each question part. Like above, suffix the variable with the part designator. Note that $variables, $domain, $reltolerance, and $abstolerance may be used for the comparison, and should not be set for individual parts.

$showanswer

By default the $showanswer for conditional types is "Answers may vary". Set $showanswer to override this.

Scaffolding

While not as simple as scaffolding multipart questions, you can add scaffolding to a Conditional question. As with multipart, put an isolated line with three slashes in the question text to indicate where the breaks occur. Then you will need to set $seqPartDone[pn] to true for each part index once that part should be considered completed. The scaffolding will move onto the next chunk when all parts in the previous chunk have $seqPartDone set to true.

Entering Math

For some types of questions, you need to enter a mathematical expression. The system follows order of operations, so use grouping symbols as much as necessary.

Many times, you can click a yellow arrow that displays next to the answer box when you click in it, which will open up the MathQuill equation editor, which you can use to help enter your answers.

Alternatively, you can enter your answer using calculator-style notation. Here is some help on how to enter expressions:
