Description:
The purpose of this study was to determine the effects of activity based teaching approach on students’ problem solving success while solving word problems that is related proportional reasoning. For this purpose, the focus was over five types of proportion related problems which are “missing value, quantitative comparison, qualitative comparison, percent and similarities in triangles”. The research was carried out pre/post-test control design. Activity based problem solving teaching was given to experimental group and traditional teaching method was employed in the control group. The research study was conducted on 134 (67 seventh grade and 69 eighth grade) middle school students. In the research three criterion referenced success tests were used for gathering data. In the face of the data collected and the evaluations made in the research, it was determined that the implementation of activity-based teaching approach had positively affected students’ problem solving success.
