As a teacher I want to be able to create sub-groups, e.g. I want to divide Group A and B into A1, A2, A3 and B1, B2, B3 in order for students to collaborate in smaller groups while at the same time being able to access the material contained in parent groups. This will also save a lot of administration time for me as a teacher.

This is how I am doing this right now: creating one group set for e.g. 5 groups with 6 students in each. Then create another group set of 30 groups with 2 students in each (pairs), this while having another window open at the computer to see the original groups to make the ‘right’ pair division from the original groups. This is time consuming and opens up for mistakes in dividing the pairs into the 'sub-groups'.

This is widely requested at our institution for courses working in seminar groups and base groups for example. The division of the students often derives from the original division.
