ABSTRACT
The aim of this research is to test the effectiveness of science teaching materials based on Science, Technology, Engineering, Mathematics, and Religion (STEM-R). The research design used is Research & Development (R&D) research with the ADDIE development model. This research also uses a pretest-posttest control group design, namely a research design with 2 comparison classes. This research was carried out at Cahaya Ilmu Islamic Elementary School, Semarang. The research subjects were class V students in the first semester of the 2024/2025 academic year, which consisted of two classes with a total of 50 students, namely 25 children as the experimental class and 25 children as the control class. Data collection techniques in this research are test and non-test techniques. The test data collection instrument uses essay questions, and the non-test data collection instrument consists of a questionnaire and observation guidelines. Data analysis techniques in research consist of normality tests, homogeneity, linear regression tests, and N-Gain tests. The results of this research are that STEM-R-based science and science teaching materials are effective in improving student learning outcomes. This is proven by student learning results during the pretest and posttest. The average student posttest score was 84.4. The results of the linear regression test show that the Sig value, namely 0.00, is less than 0.05, so it can be concluded that there is a significant influence of STEM-R-based science teaching materials on the learning outcomes of fifth-grade students at Cahaya Ilmu Islamic Elementary School. The students' n-gain scores showed that there was a significant increase from pretest to posttest or after learning with STEM-R-based science teaching materials on the learning outcomes of fifth-grade students at Cahaya Ilmu Islamic Elementary School. Next, an average calculation was carried out to obtain an average n-gain for fifth-grade students at Cahaya Ilmu Islamic Elementary School of 0.61, which is in the medium n-gain criteria. The conclusion is that STEM-R-based science and science teaching materials are effective in improving student learning outcomes.
