Six heterogeneous groups with four or five members were established based on the article,
Three Steps to Setting Up Effective Groups. (Educational Forum, 1991) (Appendix B) Group
membership was determined using the modified "select your own group' concept wherein
each student was asked to choose one classmate with whom they would want to work. Using
the students' choice in combination with my choice, which was based on the high-low
ability, groups were thus set.
