This study was carried out to examine the effect of teaching supported by discussion method on the academic achievement of 6th grade science students in the “Conduction of Electricity " unit. The study was prepared in a quasi-experimental model with pretest-posttest control group. The research was conducted in a public village secondary school in Kumlu district of Hatay province in the 2017-2018 academic year. The study was conducted with 35 6th grade students, taking into account the convenience sampling method. Experimental and control groups were randomly selected and formed. The conduction unit of electricity was taught with learning methods supported by discussion method in the experimental group and with ordinary teaching in the control group in line with the current curriculum. The application was completed by the researcher in 16 lesson hours. As a data collection tool, the "Conduction of Electricity Achievement Test", for which a validity and reliability study was conducted, was applied to both groups as pre-test and post-test before and after the application. SPSS 25 program was used for data analysis. While analyzing the data, standard deviation, mean, frequency, dependent and independent groups t-tests were analyzed. The findings reveal that the students in the experimental group showed higher academic achievement than those in the control group, and the discussion method contributed to their better understanding of science subjects. In addition, it was observed that the interaction and participation among students increased. These results show that the discussion method can be an effective tool in teaching and enrich science education. This study contributes to research on developing more effective strategies in science teaching.
