Development of Math Corner Learning Media to Enhance Elementary Students’ Understanding of Mathematical Concept

Source abstract

<p>This study aimed to develop a Math Corner and examine its feasibility and effectiveness in improving mathematical conceptual understanding among fifth-grade students at MI NU Mafatihul Ulum Sunggingan Kudus. The study employed a Research and Development (R&D) method using the Borg and Gall model, consisting of ten stages, ranging from preliminary study to product dissemination and implementation. The developed product was a Math Corner equipped with learning media, including the Number Flipbook, Fraction Game Book, and PAFELA (Factors and Multiples Board). Data collection techniques included observation, interviews, documentation, validation questionnaires, and pretest–posttest assessments. Data were analyzed quantitatively and qualitatively through expert validation, the Wilcoxon Signed Rank Test, and N-Gain analysis. The findings revealed that the Math Corner was categorized as highly feasible based on validation results from material experts, media experts, and educational practitioners. Furthermore, the implementation of the Math Corner proved effective in improving students’ mathematical conceptual understanding, as indicated by the increase in mean scores from 53.61 in the pretest to 89.44 in the posttest. The Wilcoxon test result showed a significance value of 0.000 < 0.05, while the N-Gain score of 0.77 was categorized as high. Therefore, the Math Corner is considered feasible and effective as a mathematics learning medium in Islamic elementary schools.</p>
