Verbal Interactions in Cooperative CAI by Group Composition

摘要

This study investigated verbal interaction patterns in cooperative computer-assisted instruction (CAI) by group composition.Verbal interactions of 12 two-membered groups in cooperative CAI were analyzed.Students' perceptions of cooperative CAI were also analyzed based on their achievement level.The frequencies of learning behavior for the heterogeneous group were higher than those for the homogeneous group.Especially,the frequencies of 'giving explanation','requesting a detail description',and 'requesting a repetition/confirmation' for the heterogeneous group were higher than those for the homogeneous group.On the contrary,the frequencies of 'encouraging participation' in managing behavior for the homogeneous group were higher than those for the heterogeneous group.Most students were also found to have positive perceptions of cooperative CAI and degree of cooperation in their group regardless of group composition.However,a few high-achieving students in heterogeneous group expressed negative opinions.
