Abstract

The study examines the relationship between understanding mathematical concepts and mathematical values among prospective teachers at a state university in Central Java. The research employed a qualitative approach with content analysis, involving a mathematical concept understanding test and in-depth interviews with students at high, medium, and low ability levels. The results show that students with high ability tend to possess strong mathematical values like accuracy, perseverance, and curiosity, which enable them to grasp complex mathematical concepts. In contrast, students with low ability struggle to comprehend basic mathematical concepts and often rely on rote calculation and formula use. The findings suggest that differentiated learning strategies are necessary to cater to the diverse levels of mathematical concept understanding among prospective teachers. Enhancing mathematical values can be a key factor in improving conceptual understanding in mathematics education.

Abstract

This research was conducted to develop and produce Islamic context-based mathematic learning material. The presentation of Islamic context for pre-service mathematics teachers was intended to facilitate conceptual understanding. This learning material contains rank and root, ratio and scale, and material for flat shapes and spatial shapes. The material is included in the Mathematics Materials Study course for Junior Secondary Education in the Mathematics Teacher Education program. The method in this study uses design research with the type of development study with a qualitative approach. The research phases include the preliminary research phase, the development or prototyping phase, and the assessment phase. The data were collected by filling out a learning material scoring scale by Education and Language expert and an Islamic Study expert. The quality criteria for learning material have valid results if the experts score it with excellent and valid categories. Thus, they do not need significant revision. Based on the research results, the quality of Islamic context-based mathematics learning material is classified into valid criteria at a percentage of 84% according to Mathematics Education experts and a percentage of 83.3% according to Education and Language experts and classified as an excellent category at a percentage of 94% according to Islamic Study expert. Based on these results, the product of Islamic contextual mathematics teaching materials is suitable for use in mathematics lectures.

Abstract

This study investigates the effectiveness of ethnomathematics-based learning in enhancing ninth-grade students’ mathematical problem-solving skills in geometry at an Islamic junior high school. A quasi-experimental design with pre-test and post-test was employed, involving 47 students divided into an experimental group (n = 24) and a control group (n = 23). The experimental group received instruction integrating culturally relevant contexts, while the control group received teacher-centered expository instruction. Problem-solving skills were assessed through validated tests targeting comprehension, strategy formulation, execution, and evaluation, and analyzed using normalized gain (N-Gain) and independent-samples t-tests. Results indicated that the experimental group achieved significantly higher N-Gain scores than the control group, with a large effect size, demonstrating that ethnomathematics-based learning effectively fosters higher-order problem-solving abilities. These findings suggest that embedding cultural contexts in mathematics instruction provides a more engaging and enhancing students’ problem-solving skills.
