Abstract

This study aims to examine the effectiveness of a didactical design-based teaching material grounded in Realistic Mathematics Education (RME) on the topic of circles in improving students’ conceptual understanding of mathematics. The study employed a quasi-experimental approach with a nonequivalent control group design. The participants consisted of 60 eighth-grade students from a junior high school, divided into the experimental group using RME-based learning modules and the control group receiving conventional, teacher-centered instruction. The main instrument was a conceptual understanding test developed based on six indicators: restating concepts, providing examples and non-examples, classifying, representing, explaining relationships among concepts, and applying procedures meaningfully. Results revealed that the experimental group achieved a higher mean N-gain (0.74, high category) compared to the control group (0.30, low–moderate category). The t-test showed a significant difference (p < 0.001) with a large effect size (Cohen’s d = 1.47). Analysis by indicator indicated significant improvements across all aspects, particularly in explaining conceptual relationships and mathematical representation. These findings confirm that RME-based didactical design materials effectively enhance students’ conceptual understanding of circles by facilitating meaningful rediscovery through real-world contexts and progressive mathematical modeling. Practically, the study suggests that mathematics teachers can adopt RME designs as an alternative instructional approach to promote deeper, contextual, and communicative learning in geometry.

Abstract

This study was motivated by the low level of critical thinking skills among junior high school students in solving mathematical word probleims, as evident from previous studies and the researcher's initial observations in the field. This study aims to describe the profil of junior high school students' errors in solving mathematical story problems in terms of critical thinking skills. The method used is qualitative descriptive with 32 seventh-grade students as subjects at a public junior high school in South Tambun in the 2024/2025 academic year. The research instrument was an essay test containing five story problems developed based on critical thinking ability indicators, including providing simple explanations, providing further explanations, determining strategies and techniquies, and drawing conclusions. The data were analyzed through the stages of reduction, presentation, and conclusion drawing. The results showed that most students were in the low critical thinking ability category (63%) and the rest were in the moderate category (37%), while no students reached the high category. Students with low critical thinking abilities tended to make mistakes in almost all indicators, while students with moderate abilities were able to meet most of the indicators but were not consistent, especially in determining solution strategieis and drawing conclusions. These findings indicate that the main weakness of students lies in the aspects of strategy planning and drawing conclusions, so mathematics learning that emphasizes the development of critical thinking skills through non- routine story problems and the use of targeted assessment rubrics is needed.
