The grouping model of collaborative learning in the scope of physics learning is less discussed in secondary schools. This study aims to determine the effect of gendered-grouping on the quality of collaboration in Physics Science instructional and its effect on learning outcomes. This study uses an experimental approach with a posttest only group…

Discussion of industrial-educational cooperation focuses on the Learning Curve model, which can be used to evaluate the cost effectiveness of learning programs. Cost effectiveness for homogeneous and heterogeneous groups is discussed, and the use of computers to gather information about learning achievement is considered. (Six references) (LRW)

Maintains that current research suggests that heterogeneous grouping is preferable. Reports on a study of a new mathematics curriculum using 600 students in 6 Dutch schools. Finds that students in heterogeneous classes taught with cooperative-learning techniques achieved more than students in traditional ability-grouped classrooms. (CFR)

This study examined whether graphic organizer instruction would facilitate comprehension, recall, and information transfer, and how much explicit instruction was necessary for independent generation of graphic organizers. Fifth graders read social studies information with or without graphic organizers and explicit instruction. Explicitness and…

Discussion of the effects of group aptitudes on achievement during small group learning highlights two studies that examined the effects of group composition on high and low aptitude college students. Heterogeneous and homogeneous aptitude groups are described, and an individual mastery contingency in the second study is explained. (21 references)…

Describes study that compared the achievement of high and low ability eighth-grade students working cooperatively during computer-based instruction. Homogeneous and heterogeneous grouping based on ability are explained, posttest results are analyzed, and implications for instructional design are discussed. (23 references) (Author/LRW)
