While social interaction between group members plays an important role in collaborative learning…

The use and effects of a CSCL-tool are not always predictable from the properties of the tool alone, but depend on how that tool is appropriated.

A specific group…

Supports previous findings about group outcomes by showing that communication media groups expressed lower cohesiveness than did face-to-face groups. (AEF)
