PENGEMBANGAN MEDIA PEMBELAJARAN MAGIC STAIRS MATERI SATUAN PANJANG UNTUK MENINGKATKAN HASIL BELAJAR PESERTA DIDIK KELAS III DI MI PODOREJO SUMBERGEMPOL
Abstract
This study was motivated by the low mathematics learning outcomes of third-grade students on the topic of length measurement units and the limited use of innovative instructional media at MI Podorejo Sumbergempol. Conventional teaching methods and the reliance on textbooks and worksheets resulted in low student engagement and difficulties in understanding abstract concepts. Therefore, this study aimed to analyze the needs for developing Magic Stairs learning media, describe its design and development process, examine its implementation, and evaluate its effectiveness in improving students’ learning outcomes. The study employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The product was validated by media experts, subject matter experts, and a classroom teacher before being implemented through small-group and large-group trials. The findings indicated that the Magic Stairs learning media was highly feasible for classroom use, with validation scores of 90.5% from the media expert, 100% from the material expert, and 98.8% from the classroom teacher. The implementation of the media significantly improved students’ mathematics achievement, as evidenced by the increase in the mean score from 25.50 in the pre-test to 97.00 in the post-test. The Paired Sample t-test revealed a significance value of 0.000 (p < 0.05), indicating a significant difference between students’ achievement before and after using the media. Furthermore, the average N-Gain score of 0.9630 (96.30%) was categorized as high, confirming that the Magic Stairs learning media is effective in improving students’ understanding and learning outcomes on the topic of length measurement units.
