Group collaboration and discussion within the wiki differed from discussion in LMS in several ways.
All group members’ contributions were placed in one page which made the whole text easier to read and more structured. Also, it looked like the contributions were shorter and more focused than in LMS discussions.
On the other hand, the discussion in wiki was harder to follow since all „posts“ were in one space, not separately as in space for discussion in LMS.
The affordances of wiki represent great advantage for group work – all group members can easily contribute to the common text. One of the challenges was that there were no rules for group collaboration. Another challenge is the possibility to unintentionally erase somebody else’s text.
