Constructivist Approach in Learning Chemistry: A Case of High School in Nepal

Abstract

This study examined the effectiveness of constructivist approach on learning in chemistry by using pre-test, post-test, and experimental and control group design. A sample of 32,grouped as experimental group (16) and control group (16) ongrade XII students of Laboratory secondary school were selected by using the random sampling technique.5E’s learning (Engage-Explore-Explain-Elaborate-Evaluate) strategy has been applied to experimental group and Traditional method of teaching followed by control group.Pre and post tests were used to see the difference in two groups. T-test was used to check the significance difference between experiment and control group after experiment. The result shows that Constructivist learning approach significantly improves student’s achievement in chemistry as compared to using a traditional teaching. It is therefore recommended that constructivist 5E-model strategy be used in teaching for the development of student’s higher achievement in chemistry at secondary level.
