I'd like to have this setup for a group of 70 students:
1. Students are divided in small groups of 3 or 4
2. They get a video fragment to discuss in a forum or chat,
3. This discussion will be graded by other students, they:
- provide feedback on the individual quality of the students writings and
- rank the 4 students form 1 to 4 in terms of quality of their contributions
4. This will repeat 4 times in 10 weeks.
Any ideas, tips or experiences come to mind, to make this an efficient set up?
