Abstract

Thematic learning is expected that learning activities can involve students actively and in learning activities, so that students get direct experience which makes learning activities much more meaningful. Thematic teaching materials with the STEM approach are an alternative to improve students' problem-solving abilities. This study aims to analyze the validity, convenience, attractiveness, usefulness, and effectiveness of thematic teaching materials with the STEM approach to improve students' problem solving abilities in elementary schools. This research is a type of Research and Development (R&D) research, the development is carried out according to the theory of Borg & Gall. The subjects in this study were determined using a purposive sampling technique and obtained as many as 20 students. The data collection tool uses valid and reliable test instruments. Validity data analysis techniques show that thematic teaching materials with the STEM approach are very valid to use. Effectiveness data analysis technique uses N-Gain with a calculation result of 0.57 with a significance of 0.01<0.05. Based on this research, it can be concluded that the thematic teaching materials with the STEM approach developed are valid and effective for improving students' problem solving abilities in elementary schools.

Abstract

This study aims to determine the effectiveness of inquiry-based learning model design with a realistic approach to improve students' critical thinking skills. The learning design was developed using the Borg and Gall design consisting of 10 development steps. The sample in this study were students of class IVA and IVB SDN 55 Gedong Tataan Pesawaran totaling 26 students in each class. Class IVA as the experimental class and class IVB as the control class. The results of the N-Gain test conducted obtained a value of 0.64 in the experimental class with a moderate category and 0.42 in the control class with a moderate category. The results of the independent sample t-test conducted by comparing the pretest values ​​of the experimental and control classes obtained a sig. value of 0.236> 0.05, which means H0 is rejected so that it can be concluded that there is no significant difference in the pretest values ​​of the experimental and control classes. The test results on the posttest value obtained a sig. value of 0.001<0.05, which means H1 is accepted so that it can be concluded that there is a significant difference between the average values ​​of the experimental and control classes
