Abstract

ABSTRAK Penelitian ini bertujuan mengembangkan media pembelajaran matematika berbasis game Educaplay yang terintegrasi dengan pendekatan Contextual Teaching and Learning (CTL) serta mengkaji validitas, kemenarikan, dan efektivitasnya dalam meningkatkan kemampuan komunikasi matematis siswa pada materi relasi dan fungsi. Penelitian ini menggunakan metode Research and Development dengan model ADDIE. Subjek penelitian berjumlah 28 siswa. Data dikumpulkan melalui lembar validasi ahli, angket respon siswa, dan tes kemampuan komunikasi matematis. Hasil penelitian menunjukkan bahwa media dan materi dinyatakan layak dengan skor masing-masing sebesar 3,52 dan 3,65. Uji kemenarikan menunjukkan skor rata-rata sebesar 3,25 pada kelompok kecil dan 3,31 pada kelompok besar dengan kategori menarik hingga sangat menarik. Analisis efektivitas menunjukkan peningkatan nilai rata-rata dari 51,92 pada pretest menjadi 76,82 pada posttest dengan nilai N-Gain sebesar 0,56 pada kategori sedang. Peningkatan kemampuan komunikasi matematis terlihat pada indikator menulis, menggambar, dan ekspresi matematika. Hasil penelitian menunjukkan bahwa media pembelajaran berbasis game Educaplay dengan pendekatan CTL layak, menarik, dan cukup efektif dalam meningkatkan kemampuan komunikasi matematis siswa. ABSTRACT A Research and Development (R&D) study based on the ADDIE model was conducted to develop a game based mathematics learning medium using Educaplay integrated with the Contextual Teaching and Learning (CTL) approach and to examine its validity, attractiveness, and effectiveness in enhancing students’ mathematical communication skills on the topic of relations and functions. The study involved 28 students. Data were collected through validation sheets completed by media and content experts, student response questionnaires, and mathematical communication tests. The findings indicated that both the learning media and instructional materials were valid, achieving validation scores of 3.52 and 3.65, respectively. The media was perceived as attractive, with mean scores of 3.25 in the small-group trial and 3.31 in the large-group trial. The effectiveness analysis revealed an improvement in the mean score from 51.92 (pretest) to 76.82 (posttest), with an N-Gain value of 0.56, categorized as moderate. Improvements were observed across all indicators of mathematical communication skills, including written communication, visual representation, and mathematical expression. Overall, the results suggest that the Educaplay integrated, CTL based game learning media is valid, attractive, and moderately effective in improving students’ mathematical communication skills.
