A Study of the Effects of Discussion Method on Students' Achievement in Chemistry at the High School Level Yi Mon Kyaw Kyi Swe The purpose of this research is to study the effects of discussion method on students’ achievement in Chemistry at the high school level. A quantitative research method was used to compare the students’ Chemistry achievement between the experimental and control groups. Two sample schools, No (4) Basic Education High School, San Chaung and No (6) Basic Education High School, Insein were selected by using simple random sampling method. The size of sample was (120) grade nine students from selected schools. There were two groups in each school and each group consisted of (30) students. Learning materials were selected from Grade Nine Chemistry Textbook; Chapter (15) and other extended learning materials from journals, videos and photos that are relevant to the lessons. The design adopted in this study was posttest only control group design of experimental research. The independent samples t-test was used to compare whether there were significant differences between two groups. The result showed that the students who received the treatment by using discussion method were significantly better than those who received formal instruction in BEHS, San Chaung (t = 6.015, df = 58, MD = 7.8, p < .001) and in BEHS, Insein (t = 5.088, df = 58, MD = 5.8, p < .001) Research findings revealed that teaching by discussion method had a positive contribution to the improvement of Chemistry teaching. It was concluded that teaching by discussion method was effective in raising students’ Chemistry achievement at the high school level 2018 http://hdl.handle.net/20.500.12678/0000005269 https://meral.edu.mm/records/5269
