I have been trying the workshop module to encourage peer and self assessment. I have just spent a lot of time trying to figure out why groups were not working properly.
I found out a little feature that if you enter a number of assement elements greater than the number you type up - so you have 1 blank assessmnet element at the end - you cannot see or use groups in the workshop.
The Fix is to reduce the number of elements so you donot have a blank one...
Is this a feature or have I just misunderstood something in workshops?
