A couple of different ways of showing the correct answer to a single part as soon as the student submits an answer. One way allows the student to change their answer, while the other locks the part.

A third part includes a "reveal answers to this part" button, which allows the student to choose to reveal the answer to the part.

Think very carefully before using this: by revealing the answer, you are removing the opportunity for the student to later on realise they've got that step wrong, as a consequence of some further work. It's often possible to use adaptive marking to use the student's answer in place of the correct answer in later parts.

A simple question to find the roots of a quadratic. Using to test integration of NUmbas into Canvas.

Customised for the Numbas demo exam

Motion under gravity. Object is projected vertically with initial velocity $V\;m/s$. Find time to maximum height and the maximum height. Now includes an interactive plot.

6 questions which introduce the user to the Numbas system.

The student is asked to find the square root of an integer of the form $\pm n^2$. If the root is not real, they should enter "nan".

A custom marking algorithm extends the built-in one to deal with "nan".

There's some custom javascript to set the expected answer correctly. In the future this will be possible in the marking algorithm - see https://github.com/numbas/Numbas/issues/856

Numbas Worksheet

This is a Numbas test for parametric hypothesis tests with psychology content. To be used in the mathematics wiki page.

This is a Numbas test covering linear programming techniques.

NOTE: You probably don't want to do this! There's usually a more robust way, where you get Numbas to make the expression for you.

Do not use this: alternative answers are the best way of accepting multiple correct answers.

Do not use this: adaptive marking is the best way to access the student's answer to another part.

Shows how to retrieve the student's answer to another part from a custom marking script.
