PENGEMBANGAN VIDEO PEMBELAJARAN MATEMATIKA BERBASIS PMRI PADA SISWA KELAS ENAM SD
This study aimed to develop a mathematics learning video based on Indonesian Realistic Mathematics Education (IRME) for sixth-grade elementary school students by integrating the local cultural context of Jumputan Gambo fabric. This development research employed the Rowntree model, which consists of planning, development, and evaluation stages, and was complemented by Tessmer’s formative evaluation through self-evaluation, expert review, one-to-one, small group, and field test stages. The validation results from four validators who assessed the media, content, language, and instructional design aspects indicated that the learning video was in the very valid category, with an average validity score of 92.85%. In terms of practicality, the results of the one-to-one and small group trials showed that the video was categorized as very practical, with practicality percentages ranging from 92.22% to 100%. The effectiveness test conducted during the field test stage demonstrated a significant improvement in students’ learning outcomes, with the average score increasing from 56.77 on the pretest to 85.48 on the posttest. The calculated N-Gain value of 0.70 fell into the high category, and all students achieved learning mastery. These findings indicate that the implementation of the principles of didactical phenomenology, guided reinvention, and self-developed models in the learning video effectively supports the mathematization process and students’ meaningful conceptual understanding. In addition, this study provides practical contributions for teachers in designing contextual mathematics learning that is oriented toward students’ thinking processes and aligned with the developmental characteristics of elementary school learners. Therefore, the IRME-based mathematics learning video integrating the local cultural context of Jumputan Gambo fabric is proven to be valid, practical, and effective, and has important implications for strengthening contextual mathematics learning in accordance with the Merdeka Curriculum.
