Abstract

Background: Many students face difficulties in expressing mathematical ideas due to the absence of instructional materials that connect lessons with real-world contexts. Applying a contextual approach aligned with scientific inquiry may improve students’ conceptual understanding and engagement.Aims: This research seeks to develop and assess the effectiveness of contextual teaching modules designed using a scientific framework to strengthen the mathematical representation skills of junior secondary learners.Methods: Adopting the ADDIE instructional design model, this study utilized a Research and Development (R&D) methodology involving 87 seventh-grade students from two Indonesian schools. Data collection included expert validation instruments, learner feedback surveys, and pretest-posttest measurements, with analysis based on validity, practicality, and effect size metrics.Results: Expert evaluations confirmed high validity, with average ratings of 3.71 for content and 3.73 for media. Student feedback indicated high engagement across both trial groups (mean scores above 3.3). Effect size analysis showed substantial learning gains, with Cohen’s d values of 0.82 and 0.96, indicating strong impact on students’ mathematical representation ability.Conclusion: The contextual modules developed through this study, when implemented with a scientific approach, were validated as effective tools for improving students’ ability to represent mathematical concepts. These outcomes underscore the value of integrating contextual and inquiry-driven strategies into teaching practices to make abstract content more accessible and meaningful in mathematics education.

Abstract

Latar Belakang: Kemampuan penalaran logis matematis peserta didik di Indonesia masih tergolong rendah, sebagaimana tercermin dalam hasil PISA 2022. Tujuan: Penelitian ini bertujuan untuk: 1) mengembangkan bahan ajar bilingual (Indonesia-Arab) berbantuan Visual Studio Code pada materi Sistem Persamaan Linear Dua Variabel (SPLDV); 2) menganalisis kelayakan bahan ajar berdasarkan validasi ahli; 3) menganalisis respons peserta didik terhadap kemenarikan bahan ajar; dan 4) menguji efektivitas bahan ajar dalam meningkatkan penalaran logis matematis peserta didik. Metode: Penelitian ini menggunakan metode Research and Development (R&D) dengan model ADDIE yang meliputi tahap Analysis, Design, Development, Implementation, dan Evaluation. Subjek uji coba adalah peserta didik kelas VIII di Pondok Pesantren Darul Falah (uji kelompok kecil, n=20) dan SMP Islam Nashihuddin Bandar Lampung (uji kelompok besar, n=35). Instrumen yang digunakan meliputi lembar validasi ahli (materi, media, bahasa), angket respons peserta didik, serta soal pretest dan posttest untuk mengukur penalaran logis matematis. Data dianalisis secara deskriptif kuantitatif dan menggunakan rumus N-Gain. Hasil: Bahan ajar yang dikembangkan dinyatakan sangat layak oleh ahli materi (96,88%), ahli media (87,5%), dan ahli bahasa (100%). Respons peserta didik pada uji kelompok kecil menunjukkan kategori "menarik" (82,02%) dan pada uji kelompok besar menunjukkan kategori "sangat menarik" (85,34%). Hasil uji efektivitas menunjukkan peningkatan penalaran logis matematis dengan nilai N-Gain rata-rata 0,563 (kategori sedang) pada uji kelompok kecil dan 0,596 (kategori sedang) pada uji kelompok besar.
