Abstract

• The main purpose of the present study is to study the effectiveness of information processing model on students’ achievement in Grade Ten Chemistry. The posttest only control group design was used for this study. Two sample schools in Yangon Region were selected by random sampling method. The participants in this study were (120) Grade Ten Chemistry students from two selected schools, and they were randomly selected. The experimental group was taught by information processing model. The instruments used in this study were posttest and attitude survey questionnaire. Learning materials were selected from Chapter (12), Hydrogen and Chapter (13), Water from Grade Ten Chemistry Textbook. The experimental group was taken about four weeks (20 days). Independent samples ‘t’ test was used to test the hypotheses of this study. Examination of means and ‘t’ test indicated that the experimental group achieved significantly higher than the control group at the knowledge, comprehension, application, and higher level of posttest questions. The qualitative data also supported the findings from the experimental groups from selected school were given a questionnaire. It consists of (20) items five-point Likert-scale. The result showed that the students expressed their willingness to learn in information processing model and they had positive attitudes towards information processing model and learning chemistry. So, it can be verified that information processing model brings positive effects on students’ achievement in Grade (10) Chemistry.
