Thx again for the reply.
Well, not really. What if we want to allow the students to choose who they wants to be in group with? Which is normally the case. Then the "assign to everyone" might still be a problem. Of course, if we automatically assign all students to groups, then I guess we could leave the "assign to everyone", but the students will not be very happy with this. But by assigning a task to ONLY the groups within a group set we make sure that it is not possible to submit indiviually. Therefore, it is frustrating that you haved to add one by one group of the group set, and not being able to highlight all groups and then add/assign all these.
Bottom line is that we find the whole group assignment bit really challengig for many reasons. Teachers don't understand the logic behind it and thus does several errors causing them a lot of headache. And we have many courses where group assignments are part of the mandatory requirements to complete a course.
I think we just need to educate our teachers better on how to set up group assignments.
