Abstract

Mathematical problem-solving skills are one of the important competencies that elementary school students must have, especially in learning mathematics on fractions. However, in reality, these skills are still relatively low, partly due to the use of learning approaches that lack context. This study aims to determine the effect of the Contextual Teaching and Learning (CTL) approach on the mathematical problem-solving skills of fifth-grade elementary school students on fractions. This study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. The study was conducted at PAB 29 Manunggal Private Elementary School with a sample of 27 students from fifth grade classes A and B. Class V A, as the experimental class, was given treatment using the CTL approach, while class V B, as the control class, used conventional learning. The research instrument was an essay test of mathematical problem-solving skills. The data were analyzed using parametric statistical tests with the Independent Samples t-test after meeting the prerequisites of normality and homogeneity. The results showed that the average post-test scores of the experimental class were higher than those of the control class, and there was a significant difference in mathematical problem-solving skills between the two classes. Thus, it can be concluded that the Contextual Teaching and Learning approach is effective in improving students' mathematical problem-solving skills.

Abstract

This study aims to develop a differentiated mathematics e-book based on Langkat Malay culture that is feasible, effective, and practical in improving the functional thinking and critical thinking abilities of junior high school students. The research method used is Research and Development (R&D) with the 4-D Thiagarajan model which includes the stages of define, design, develop, and disseminate. The research subjects were students of Private Junior High School PAB 13 Langkat, with data obtained through functional thinking and critical thinking tests, expert validation questionnaires, and teacher and student response questionnaires. The results of the study showed that from the aspect of feasibility, validation by material, language, and design experts obtained an average percentage of 88.6% which is included in the very feasible category. From the aspect of effectiveness, the use of e-books is proven to improve functional thinking abilities with an average N-Gain of 0.70 and critical thinking abilities with an average N-Gain of 0.72, both of which are included in the effective category. In terms of practicality, teachers responded 89.3% and students 87.9%, with an average of 88.6%, which is considered very practical. Therefore, the differentiated mathematics e-book based on Langkat Malay culture can be used as an alternative innovative teaching material that is not only in line with the curriculum but also culturally relevant, and able to improve students' higher-order thinking skills. This product has the potential to contribute to enriching mathematics learning resources that are contextual, interactive, and support 21st-century learning.
