To place students into workgroups, to work separately on the same activity (such as group A, B, and C all discussing in a forum on technology) they just need to be put into groups. To have students working on different activities, not even seeing activities for other groups (such as group A writing a report, group B using a forum, and group C creating a wiki), you need to put them in groups first, such as group A, B, and C, THEN you must place each group in their own grouping, such as Grouping A containing Group A, Grouping B containing group B, etcetera. Grouping refers to the collection of group collections. Usually, the use of grouping is to set different size groups depending on the type of activity. For example, for a forum, each group has 9 students. For wiki activity purposes, each group has 3 students.
