Abstract

• The main purpose of this study is to investigate the applicability of Biological Science Inquiry Model (BSIM) in teaching high school biology in Myanmar. This study was conducted in four basic education high schools from Yangon Region. Simple random sampling method was used. From each school, two groups of students from Grade Ten were randomly selected as participants. The instruments were pretest, posttest, lesson plans, materials and questionnaires. The research design was nonequivalent control group design. The research findings include three main parts. Firstly, the experimental groups who received BSIM were significantly higher than the control groups who did not. Secondly, the stronger the attitudes towards BSIM were established, the higher the biology achievement. Thirdly, the best predicting factor was interest; the second predictor was appreciation and the third predictor was value towards BSIM. Therefore, BSIM contributed a positive impact on teaching high school biology. The research findings suggested that BSIM should be used in teaching and learning high school biology in Myanmar.
