Abstract:

The aim of this study is to investigate the effects of problem solving strategies used with cooperative learning on problem solving success of 9th grade students. In line with this aim, pre-test post-test research design with control group was used. The study group of the study is composed of 71 students, 35 of whom are in the experimental group and 36 are in the control group. The students in the experimental group studied the topic of “Problems” with worksheets in cooperative learning groups for 30 hours. In the control group, the topic of “Problems” was studied for 30 hours with traditional instruction method. Data for the study was collected with “Problem Solving Test”, which included 20 items. The results of the data analysis suggested that there is no significant difference between the experimental group and the control group in terms of students’ problem solving success. 5 months after the application, the post-test was applied as the retention test. As a result of the data from the retention test, it was seen that the effects of the experimental method lasted longer and that problem solving strategies used in combination with cooperative learning are effective to achieve the retention of information with regard to problem solving
