Coursera - Problem Editor
Not much information on the problem configuration options for Coursera course authors are available, but spot-checking Coursera courses and consulting what resources I was able to get access to, the following question types were identified:
Multiple choice
Checkboxes
Free-text entry with a character limit (auto-graded)
Peer- and staff-graded assessments
Questions on Coursera are mostly limited to quizzes, which are listed in course outlines, but can also occur within videos, as a significant amount of Coursera content is in the form of video lectures.
