For an exam that needs to be conducted online, one recommended approach is to set it up in Canvas Quizzes, and have students take it in conjunction with the Respondus LockDown Browser. Combining these tools will prevent students from opening other sites on the same computer, or copying/pasting from other applications. It will also provide features that facilitate administering timed exams, release and closing dates, and section-specific exams.
How to Access LockDown Browser
LockDown Browser integrates easily within U-M Canvas, and is available to College of Engineering instructors at no cost. An instructor can add it to their Canvas course site via the Navigation tab in the site Settings. Refer to Enabling External Apps.
If you are interested in using the LockDown Browser, the LSA Technology Services help page provides a good starting point.
Nexus also provides general information for getting started with offering exams and assessments online using Canvas. Refer to their Minimum Quality Standards for Remote Exams and Assessments document, and their Offering Quizzes and Exams Remotely video tutorial:
