Abstract

The integration of cultural and realistic contexts in mathematics learning has shown significant potential in fostering critical thinking skills; however, existing educational resources often lack a comprehensive approach that effectively combines these aspects. Addressing this gap, this research aimed to develop a novel Ethno-Realistic Mathematics Education (Ethno-RME)-based three-dimensional learning module that meets the criteria of validity, practicality, and has a positive impact on students' critical thinking skills. Utilizing a Design Research methodology, specifically a development study, the research was conducted in two stages: Preliminary Evaluation and Formative Evaluation, involving 12th-grade students from SMAN 5 Purworejo as participants. Data collection included product quality assessment sheets evaluated by material and media experts, student response sheets, and critical thinking test instruments. The results demonstrated that the module achieved high validity, with content rated "Good" (average score: 141 out of 175) and media rated "Very Good" (average score: 131 out of 135). Practicality was confirmed through student responses, with small group and field test average scores classified as "Very Good" (72.33 and 72.36, respectively). Furthermore, post-test results for critical thinking skills revealed an average score of 75.51, indicating the module’s potential to enhance students’ critical thinking. These findings establish the Ethno-RME-based module as a valid, practical, and impactful teaching resource, offering a culturally relevant and application-oriented alternative for mathematics education.

Abstract

Mathematics education in elementary schools plays an important role in developing students' logical and analytical thinking skills, but many still experience difficulties in understanding and solving mathematics problems that require critical thinking. This research aims to analyze the effectiveness of the Problem Based Learning (PBL) model in improving the mathematical problem solving abilities of fifth grade students at SD Muhammadiyah Mlangi. The method used is the Kemmis and McTaggart model of classroom action research, including planning, implementation, observation and reflection. The research subjects consisted of 27 class V students. Data was collected through evaluation tests and observation of student activities in PBL-based learning, then analyzed comparatively descriptively. The research results show that the application of PBL has a positive impact on students' problem solving abilities. The average value increased from 65.87 in the pre-cycle to 77.95 in Cycle I and 86.44 in Cycle II. Students also become more active and confident in solving math problems. These findings indicate that PBL is effective as an innovative learning strategy in improving the quality of mathematics learning in elementary schools
