Abstract

Penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan instrumen tes pemecahan masalah  pada materi vector sehingga dapat digunakan sebagai bahan instrumen penilaian yang dapat mengukur kemampuan kognitif siswa. Jenis penelitian ini ialah penelitian R&D (Research and Development) dengan menggunakan model pengembangan 4D (Define, Design, Develop, Dessiminate) dimana pada penelitian ini hanya sampai pada tahap Develop. Subjek penelitian ini yaitu siswa-siswi kelas X IA-1 dan IA-2 SMAS Brigjen Katamso-01 Medan. Data penelitian diperoleh berdasarkan uji kelayakan instrumen tes (validasi, realibilitas, taraf kesukaran, daya pembeda, dan respon siswa). Validasi ahli dari 3 validator menghasilkan nilai rata-rata sebesar 86% yang bermakna instrumen tes layak untuk diujikan. Reliabilitas dari kelas pengembangan sebesar yaitu 0,63 dan dikatakan reliabel. Hasil uji respon siswa didapatkan bahwa persentasi respon positif dari 16 sampel sebesar 91.88% dalam katagori sangat baik, Hasil kemampuan kognitif siswa dalam mengerjakan instrumen tes pemecahan masalah tersebut sebesar 55,1 kelas kecil dan 54,4 kelas besar. Berdasarkan hasil tersebut dapat disimpulkan bahwa instrumen tes pemecehan masalah pada materi vector memenuhi hasil pengujian kelayakan instrumen tes sehingga dapat digunakan sebagai bahan untuk mengukur dan menilai kemampuan kognitif untuk pemebelajaran tatap muka maupun daring.

Abstract

Teachers need well-designed learning materials to achieve instructional objectives. In the P3FIS course, students are required to develop such materials; however, many still lack sufficient understanding to design them effectively. The required components include the Annual Teaching Flow (ATP), semester and annual programs, and teaching modules consisting of teaching materials, learning media, student worksheets, and learning evaluations. Observations of Class B Physics Education students in 2022 indicated that many students come from Batak ethnic backgrounds. To create more contextual and meaningful learning, culturally responsive learning materials grounded in Batak culture are necessary. This study aimed to develop learning materials that are valid, practical, and effective. The research was conducted in the Physics Department at Universitas Negeri Medan using a Research and Development (R&D) approach with the ADDIE model, which includes analysis, design, development, validation, implementation, and evaluation stages. The product developed was a comprehensive set of learning materials validated by three experts. Validation results showed scores of 81.7%, 83.1% and 80.3%, indicating high validity. Practicality results reached 83% in the small group and 93.62% in the large group. The effectiveness test produced an N-gain score of 0.65 (moderate category). Thus, the CRT-based learning materials grounded in Batak culture are considered highly valid, practical, and effective.
