This study aims to develop mathematics teaching materials incorporating the traditional Javanese gamelan cultural context in the topic of circles to improve students’ mathematical problem-solving skills through the Problem Based Learning (PBL) model. The research employed a Research and Development (R&D) approach using the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation stages. The research subjects included eighth-grade junior high school students, mathematics teachers, and instructional design and content experts. Data were collected using expert validation sheets, teacher and student response questionnaires, classroom observation sheets, and mathematical problem-solving ability tests. The data were analyzed using qualitative and quantitative descriptive techniques, including N-Gain analysis to measure improvements in students’ problem-solving abilities. The results indicate that the developed teaching materials are valid and practical for classroom use. Furthermore, the implementation of gamelan-based teaching materials integrated with the PBL model was proven effective in enhancing students’ mathematical problem-solving skills in circle topics. The integration of local cultural contexts into mathematics learning increases student engagement, strengthens conceptual understanding, and creates meaningful and contextual learning experiences. Therefore, the developed teaching materials are suitable as an innovative alternative for mathematics instruction at the junior high school level.

PENGARUH PENGGUNAAN GAME EDUCAPLAY UNTUK MENINGKATKAN MOTIVASI BELAJAR DAN KEMAMPUAN KOGNITIF PESERTA DIDIK SMP NEGERI 1 ENDE PADA MATERI USAHA DAN ENERGI

This study aims to analyze the effect of using the Educaplay game on students’ learning motivation and cognitive abilities at SMP Negeri 1 Ende on the topic of Work and Energy. The research employed a one-group pretest–posttest design involving 20 students as the sample. The instruments used in this study were a learning motivation questionnaire and a cognitive ability test. The results showed that after the implementation of the Educaplay game, students’ learning motivation was categorized as high, with an average percentage of 80.2%. In addition, students’ cognitive abilities improved significantly, as indicated by the increase in the mean pre-test score of 58.00 to a mean post-test score of 87.00. The t-test analysis revealed a Sig. (2-tailed) value of 0.000 < 0.05, indicating a significant difference between the pre-test and post-test scores. Therefore, it can be concluded that the use of the Educaplay game has a positive and significant effect on students’ learning motivation and cognitive abilities.

PENGARUH MODEL PROBLEM BASED LEARNING (PBL) TERINTEGRASI KAHOOT TERHADAP PEMAHAMAN KONSEP FISIKA SISWA MAN ENDE

This study aims to determine the effect of implementing the Problem Based Learning (PBL) model integrated with Kahoot! on students’ understanding of physics concepts in Grade XI Science at MAN Ende. The study was motivated by students’ low conceptual understanding, reflected in their difficulty relating physics material to real-life contexts and their limited active participation in classroom learning. This research employed a quasi-experimental method using a one group posttest-only design. The participants were 25 students in the 2025/2026 academic year. The research instrument consisted of 30 multiple-choice questions, including 10 Kahoot-based items and 20 printed items. Data were analyzed using descriptive statistics, a normality test, and a one-sample t-test. The results showed an increase in the mean score from 63.2 to 90.6, with Sig. (2-tailed) < 0.05, indicating a significant positive effect on students’ conceptual understanding of physics.
