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.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran berbasis masalah terhadap kemampuan pemecahan masalah siswa pada materi suhu dan kalor di kelas XI SMAS RK Deli Murni Sibolangit T.P 2023/2024. Jenis penelitian ini adalah kuasi eksperimen dengan mengunakan non equivalent control group. Populasi dan sampel dalam penelitian ini adalah seluruh siswa kelas XI IPA SMAS RK Deli Murni Sibolangit T.P 2023/2024 dan siswa kelas XI IPA1 sebagai kelas kontrol dan siswa kelas XI IPA2 sebagai kelas eksperimen. Instrumen yang digunakan adalah tes kemampuan pemecahan masalah yang terdiri dari 10 butir soal uraian. Sebelum diberikan perlakukan yang berbeda diberikan pretest, dengan perolehan rata-rata untuk kelas kontrol adalah 14,52 dan kelas eksperimen adalah 15,74. Hasil uji t untuk pretes yaitu tidak terdapat perbedaan rata-rata kemampuan pemecahan masalah pada kelas eksperimendan kontrol. Hasil perolehan postes yakni rata-rata kemampuan pemecahan masalah kelas kontrol adalah 66,71 dan kelas eksperimen adalah 76,32. Hasil uji t menunjukkan bahwa terdapat perbedaan rata-rata kemampuan pemecahan masalah pada kelas eksperimen dan kontrol.
