How do I create a Formula question in New Quizzes?

When creating an assessment, you can create a Formula assessment question in New Quizzes. In a Formula question, students need to type in the correct numerical answer.

You can also duplicate Formula questions to create a new question.

Note: View information about Canvas Formula Quiz Question Helper Functions.

Add Question

Add Question

To create a question, click the Add button anywhere in the assessment.

Add Formula Question

Add Formula Question

Click the Add Formula button.

Add Question Title and Stem

Add Question Title and Stem

In the Question Title field [1], add a question title. Question titles are optional and are not visible to students.

In the Question Stem field [2], add the question stem. The question stem contains the question and, if necessary, additional instructions and information. You can use the Rich Content Editor to format and add content to your question stem.

Identify variables in your question by surrounding variable names by backticks. (e.g., a variable name of x can be identified by typing `x`.)

Add Variable Answers

Add Variable Answers

After typing the question with the variable, parameters to define the formula will display [1]. Set the variable answers for the formula. Specify the minimum [2] and maximum [3] values for the variable. Select decimal places in by using the increase or decrease arrows [4].

Add Formula Definition

Add Formula Definition

Type the formula definition in the formula field. Make sure the formula does not contain any brackets or equal signs.

Notes: The Formula Definition supports the following operators: + (add), - (subtract), * (multiply), / (divide), and ^ (power).

Generate Possible Solutions

Generate Possible Solutions

Specify the number of possible solutions you want to generate in the Number of solutions field [1]. Then select the number of decimal places required in the Decimal places field [2].

In the Margin type field, select the absolute or percent margin type [3]. Enter the margin of error for the student's answer in the +/- margin of error field [4]. Responses are based on relative error in addition to absolute error. Margins of error can be created as a percentage or as a point value (up to three decimal places).

To display solutions in scientific notation, click the Display as Scientific Notation button [5].

To view possible solutions, click the Generate button [6].

View Possible Solutions

View Possible Solutions

Possible solutions will process according to the number of value combinations.

Set Options

Set Options

To allow students to use an on-screen calculator for this question, click the Show on-screen calculator checkbox [1].

If you select this option, you can enable a basic calculator [2] or scientific calculator [3]. The basic calculator displays numbers and basic math functions (add, subtract, multiply, divide). The scientific calculator displays more options for advanced calculations.

Note: The on-screen calculator option is intended to be used while displaying one question at a time. If the assessment does not display one question at a time, students may be able to use the calculator for all questions.

Align to Outcome

Align to Outcome

To align the question to an outcome, click anywhere in the Align to Outcomes section.

Add to Item Bank

Add to Item Bank

If you want to save a question to use in other assessments, you can add it to an item bank.

To add the question to an item bank, click the Add to Bank link.

Note: After a question has been added to an item bank, it can only be edited in the item bank. You can still set unique point values and options in the assessment for an item bank question.

Add Point Value

Add Point Value

To customize the point value for the question, type the point value in the Points field [1] or use the arrows to increase or decrease the point value [2].

Save Question

To save the question, click the Done button.

Comments

I noticed that display as scientific notation removes the ability to apply a margin of error to the questions, which is a huge problem because in testing I found that an answer of 1.2 would be marked incorrect against a correct answer of 1.20 and vice versa.  The margin of error needs to be added to scientific notation otherwise it is useless.

The mechanism for entering scientific notation is also problematic.  Most of us are accustomed to using the “E” format in calculations, such as 1.20E-2, but the formula question uses 1.20*10^-2, which is really convoluted.  The formula questions need to accept both or the easier “E” format.

I haven't tested the margin of error, but I've found that I have to give explicit directions regarding the number of decimal places. If I set it to require two decimal places, even if the answer is a whole number, two trailing zeros are required, so 12 would be wrong but 12.00 would be marked correct. I find the notation using E to be simpler also because it is how Excel formats scientific notation. My students are more familiar with 1.20*10^-2 though. I agree this is more typing and more room for error, but I think students are more comfortable with it because it's how they have to input scientific notation on their graphing calculators.

Hi @pcharles and @JoeBattistelli

Thank you for your comments here. From what @JoeBattistelli says, it sounds like there's a workaround for students. However, feel free to search through the Ideas Conversations forum for any Canvas feature ideas that might meet your needs.
