Use of Integrated Thematic Teaching Materials Based on Problem Solving in Natural Science Learning in Elementary Schools

The purpose of this study is to determine the effectiveness of the use of integrated thematic teaching materials based on problem-solving skills developed in natural science learning in elementary schools. This research design applies two groups of respondents, namely the Experimental Class Group and the Control Class Group. This study refers to the concept of the pretest-posttest control group with the data analysis technique used is descriptive statistics and t-test. The results of this study indicate that the use of integrated thematic teaching materials developed in natural science learning is significant, thus it can be concluded that learning using thematic learning material is based on problem-solving skills in natural science learning can improve elementary school student learning achievement.
