Strategies applied in this study consisted of a metacognitive strategy combined with cooperative learning (MSCL) and one without cooperative learning (MS). Both strategies used the self-understanding and evaluation sheet (SUES). The aims of this study were to investigate the effect of MSCL and MS on the quality of the learning process in genetics…

The authors investigated the comparative effect of the learning cycle and expository instruction on 8th-grade students' achievement in genetics. They adopted the nonequivalent control group design as a type of quasiexperimental design. The experimental group (N = 104) received learning cycle instruction, and the control group (N = 109) received…

Examines various types of problems that researchers have used to demonstrate problem solving. Focuses on genetics problems. Discusses classes of learning outcomes, conceptual knowledge gains, content-independent heuristics, content-specific procedures, understanding the nature of science and a typology of genetics problems.
