THE EFFECT OF PROBLEM BASED LEARNING ON STUDENTS’ SCIENCE LEARNING ACHIEVEMENT AT GRADE IV ELEMENTARY SCHOOLS

Abstract

This research aimed at investigating the difference in science learning achievement between students studying through problem-based learning and those studying through conventional learning. 10 grade IV elementary school students were selected as research samples and they were divided into two groups : an experimental group and a control group . Those groups had been equalized by conducting Product moment analysis. This study utilized a post-test-only control group design. Learning achievement data were collected by using a multiple-choice test method. The test validity was examined by using Point Biserial while the test reliability was examined by using KR-20. Before testing the hypothesis, t he data were processed with prerequisite test namely Normality Test (with a significance = 0.2), Variant Homogeneity Test (with a significance of 0.158), Box'M Test (with a significance = 0.146), and the Correlation Test between Dependent Variables / Multicollinearity (Tolerance and VIF =1). The n, the hypotheses were tested by using MANOVA (Multivariate Analysis of Variance). The research finding showed that: there was a significant difference in science learning achievement between students studying through problem-based learning and those studying through conventional learning (F=5.574 and sig.=0.046; p<0.05).
