Learning Modules - format can integrate mini teaches (video/content notes) among questions, presented in one slide at a time format. Also the format for online testing (ie only one submission accepted, no feedback immediately offered) and the only format that offers an optional timer within a larger accessibility window (ie a 30 minute quiz taken within a 2 hour window).
Web - all questions displayed together in pdf format; the most common for homeworks. Settings could be set (but are not the default) to invite just one answer choice. Immediate feedback (right/wrong) is provided.
Manually Graded - essay and student file uploads you want your eyes on.
Less likely to be used during fall 2020:
Bubble (UT only) - when on campus a standard for in-person exams involving multiple choice tests. (Quest has a scantron scanner in PMA 15.320G)
Classroom Response and Quest -small intervals of open learning modules can also serve the same function (ie take this assignment, open for 3 minutes).
