| Abstract: | This study examined the effects of a teaching strategy in which fifth-grade students evaluated the strengths or weaknesses of solution methods to pattern finding problems. The experimental and control group each consisted of thirty four elementary students in Japan who took the pre, post and retention tests. The experimental group showed a significantly better performance on the retention test although no significant differences were observed on the pre and post tests. This result suggests that the evaluation and improvement activity was important as a teaching strategy. |
