The effectiveness of problem solving strategy in the solution of geometric optical problems

In this study, a number of problem solving methods and problem solving strategies developed by the researcher in the teaching of "Optic" unit in the 10th grade physics lesson of secondary school were tried to be proved the effectiveness of the students on their academic achievement and attitudes towards optic unit. A mixed method was used in the study. The research was carried out on three groups formed by 95 tenth grade students studying at Erzincan Milli Egemenlik Anatolian High School during the spring semester of 2015-2016 academic year. For Experiment 1 group, many problems were solved by traditional method, for Experiment 2 group, problem solving strategy and for control group, traditional expression method was used. Before and after Denel procedures, Physique Academic Achievement Test developed by Bülbül (2009) and Optical Attitude Scale developed by K. Şengören (2006) were applied to all three groups. In the analysis of the obtained data, independent t test and ANOVA in the SPSS 20 package program were used. According to the results of the research, it is seen that the students in the experimental group 2, who were taught by the problem solving strategy, were statistically more successful than the students in the experimental group 1 who solved a large number of problems and the students in the control group in which they were taught by the traditional expression method
