Timer in MATLAB Grader

I am looking to implment a timer in MATLAB Grader assignments.

I am hoping to measure time to completion or set a countdown timer to limit time on a given question.

I don't think a timer will work the way you are wanting. MATLAB Grader only has a transactional connection to a MATLAB worker. MATLAB is only running from the time they click "Submit" to when a result/grade is returned. After that, the worker they were connected to is reset. The next time they click submit, they get a new, clean worker. There is no persistance of variables or settings.

Are you running your course on MATLAB Grader or are you using LMS integration?

[Joseph Martel-Foley]

I am using solely MATLAB Grader for quizzes at the moment.

We do not have LMS integration at this point. Would that allow for the LMS timing system to control the access?

[Cris LaPierre]

Unfortunately no, it wouldn't change the behavior of MATLAB Grader problems, but an LMS might provide additional tools to control how students view material in a course.

How are the quizzes assigned? Are they administered in class? Do students all start and stop at the same time?

[Joseph Martel-Foley]

I am adjusting how I do the quizzes. In class and timed ensures some consistency but with 108 students it is not easy to make sure they all finish at the same time.

I am also looking into mastery grading but this tends to lead students to google answers rather than try to complete it themselves.
