The effect of cooperative learning method on the success of the student and the permanence of the knowledge in teaching of genetics unit during science lesson in 8th grade of primary school

The main goal of this research is to argue the affect of subjects of heredity unit, taking part in primary education 8th grade science lesson, taught through the cooperative teaching method on the successes and permanence of the learners.The technique including the initial and the final tests were applied throughout the research. The environment and exemplification of the research were 76 8th grade students from Dumlupınar Primary School located in Etimesgut province of Ankara. The 8/A students were experiment group and the 8/B students were the control group.The success test made up of 25 questions and prepared by the researcher was applied as the initial, final and the observation tests to both experiment and the control group. The t-test and the one way ANOVA (the f-test) was used in the evaluation of the results of the initial, final and observation tests to have independent samples and the statistical package (SPSS 17.0 for Windows) program was used for the education sciences test. The method of the experiment group was cooperative learning whereas the explanation was the control group?s method.The cooperative learning method was proved to better to improve the success than the traditional methods in the teaching process of the subjects of heredity unit in 8th grades of primary schools. In addition the knowledge learned through the cooperative method was seen to be more permanent.The key words: The cooperative learning method, student success, permanence
