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.

Abstract

This study aims to find out how the results of the development of the e-module are to determine the feasibility of the phet virtual laboratory-assisted e-module based on material experts, and media experts, and to find out the practicality of the phet virtual laboratory-assisted e-module based on the responses of students and physics teachers . The type of research used is research and development (R&D). The research model developed is ADDIE (Analysis, design, development, implementation, evaluation). The subjects in this study were all 37 students of class XI IPA at SMA PAB 4 Sampali. Based on the results of the trials that have been carried out, validation results are obtained from material experts with an average percentage score of 93% which is categorized as very feasible, while from the validation results of media experts with an average percentage score of 94% so that it is categorized as very feasible. Then to find out practicality can be seen from the percentage of scores on the response questionnaire of students who obtained a percentage score of 85%, while for the results the percentage score for physics teachers was 90%, so that overall the e-modules that have been developed are in the very practical category.
