An article about group design and selection collaborative learning.
This study investigates whether instructor-formed heterogeneous groups produce a more effective CL environment than student self-selected groups by measuring individual academic performance and perceptions. Results indicate the presence of a treatment interaction, implying that the best group composition may not be the same for all students. In some circumstances, higher ability students had statistically higher performance in more homogeneous groups. Lower ability students did better (not significant) in heterogeneous groupings. The majority of students gave high ratings to the impact of CL on learning and development of team skills. Students were only mildly interested in increasing the time spent in groups, indicating that they value both traditional teaching methods and CL.
