Abstract

This study aims to determine the development stages, feasibility level, practicality level, and effectiveness of a local wisdom-based children's magazine designed to enhance the mathematical problem-solving skills of Grade V students at SDN Pagojengan 02. The study employs the Research and Development (R&D) method using the Borg and Gall model, which consists of ten stages ranging from research and information gathering to dissemination and implementation. Effectiveness testing utilized a Pre-Experimental Design approach, specifically the One-Group Pretest-Posttest Design. The research subjects were Grade V students at SDN Pagojengan 02. Research instruments included expert validation sheets, teacher and student response questionnaires, observation sheets, and mathematical problem-solving skill tests. The results indicate that the local wisdom-based children's magazine achieved a "Highly Feasible" rating, evidenced by validation scores of 94.9% from the subject matter expert, 92.3% from the media expert, and 96.2% from the language expert. Regarding practicality, the magazine was rated "Highly Practical," with trial percentages of 88% (small-scale), 89% (medium-scale), and 90% (large-scale), resulting in an average of 89%. Effectiveness test results showed a Paired Sample t-Test significance value of 0.000 (<0.05), indicating a significant improvement in students' mathematical problem-solving skills after using the local wisdom-based children's magazine. This improvement was further supported by an N-Gain score of 0.59, falling into the medium category. Thus, the local wisdom-based children's magazine that was developed is deemed highly suitable, highly practical, and effective for use as a learning medium to enhance the mathematical problem-solving skills of fifth-grade elementary school students.
