EFFECT OF USING A PROBLEM BASED LEARNING MODEL ON THE LEARNING OUTCOMES OF FOURTH GRADE SCIENCE AND TECHNOLOGY STUDENTS AT SD NEGERI 74 PALEMBANG

This study aims to determine the effect of using a problem-based learning model on the learning outcomes of IPAS students in class IV SD Negeri 74 Palembang. This research used quasi-experimental design method with nonequivalent control group design type. The population in this study were all fourth grade students of SD Negeri 74 Palembang. The sample taken in this study was 58 students who were divided into experimental and control classes. The sampling technique in this study used purposive sampling technique.
