Use Gradebook data to discourage cheating

Students who consistently don't submit work may have dropped the course. Or these accounts may have become phantom students, a possible cheating method. The accounts should be suspended or disenrolled.

Below, student Last13, First13 should be suspended, and perhaps ultimately disenrolled.

You can check how long students spend on an assignment by displaying the Time tab in the Mastering Gradebook or by exporting times or difficulty ratings. Students who cheat may do well but spend a very short time on answers.

From the Gradebook you can drill down to see a student's work on an individual assignment, including any item, item part, or individual answer. Examining the individual work of multiple students can reveal patterns of possible answer sharing. Time of submission can also be important.
