What Should be Considered in Group Formation for Open-end Tasks?

In this paper, we analyze learner data of 157 students in a cooperative learning course. The relation between learner attributes of the group member and group cooperative learning performance are explored. The analysis results suggest that the group performance was directly affected by the lowest indicator addressing the use of knowledge assimilation strategy and effort management strategy, and the lowest active indicator (based on the Index of Learning Styles) among the group members.
