I have recently started learning with Coursera and find It a great platform with lots to offer.
I have suffered from "Insufficient Reviews" for the assignment that I has submitted. I feel the problem arises out of a course members' inability to know if and how many people are currently taking the same course. This can be solved with a Course Dashboard.
- It would be better, if at the time of enrollment, the page displays how many students are enrolled in that course and are currently at which level (modules or weeks). All the data is already available to Coursera, its only about getting it displayed at the time of enrollment.
- During the same course, the Dashboard can inform a student about the progress of other members and help him/her to adjust the learning pace in order to predict that sufficient reviewers will be available for the assignment submission.
