Abstract

Understanding abstract concepts is still a major challenge in learning science and mathematics at the elementary school level. This study aims to test the effectiveness of a STEM-based Collaborative Learning approach to improving students' understanding of abstract concepts. This study used a quasi-experimental method with a one-group pretest-posttest design, involving 25 fifth-grade students from an elementary school in Jakarta who were selected through purposive sampling. The research instruments consisted of abstract concept comprehension tests (pretest and posttest), collaborative involvement observation sheets, and student participation questionnaires. Data analysis was carried out quantitatively using a paired sample t-test and supported by thematic qualitative analysis. The results showed that there was a significant increase in the abstract concept comprehension score, with an average pretest score of 62.2 increasing to 75.9 on the posttest. The t-test results obtained a value of t = -45.0 with p <0.001, which indicates the statistical effectiveness of the intervention. Observations and questionnaires showed high student involvement in group discussions and collaborative application of concepts. The conclusion of this study is that STEM-based Collaborative Learning is able to facilitate the learning of abstract concepts in a more meaningful and participatory way. Suggestions for further research are to test the effectiveness of this approach at different levels and to explore its integration with digital technology to strengthen students' absorption of abstract, cross-disciplinary material.

Abstract

The low level of numeracy literacy among students in the city of Bima and West Nusa Tenggara requires more contextual and relevant learning innovations that are relevant to local life and culture. This study aims to develop an Project Based Learning (PjBL) based ethno-STEM to improve the numeracy literacy of elementary school students. The research method used a research and development approach, which included needs analysis, model design, expert validation, limited trials, and effectiveness testing at SDN 11 Kota Bima. Data collection instruments consisted of questionnaires, observation sheets, and numeracy literacy tests. The validity test results showed that the Project Based Learning (PjBL) based ethno-STEM met the criteria for content, language, and implementation feasibility. The application of the model in field trials provided a significant improvement in students' numeracy literacy skills compared to conventional learning, as indicated by higher post-test scores and positive responses from teachers and students. These findings confirm that the integration of local culture in project-based learning effectively improves students' understanding of mathematical concepts and problem-solving skills. This study concludes that the Project Based Learning (PjBL) based ethno-STEM can be an alternative contextual and relevant learning innovation to improve numeracy literacy in elementary schools
