Abstract

Penelitian pengembangan ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah kontekstual dan kesulitan peserta didik kelas VII dalam memahami konsep bilangan rasional di SMPN 21 Bogor, sehingga diperlukan inovasi media pembelajaran. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis website dengan pendekatan Contextual Teaching and Learning (CTL) pada materi bilangan rasional kelas VII SMP dan menentukan kelayakannya. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan menggunakan tahapan model pengembangan 4D yang meliputi tahap define, design, develop, dan disseminate. Media pembelajaran interaktif berbasis website dikembangkan menggunakan Adobe Animate dengan output HTML agar responsif di berbagai perangkat, serta mengintegrasikan tujuh komponen CTL ke dalam alur belajar terstruktur. Pengumpulan data dilakukan melalui instrumen wawancara, angket kebutuhan, tes kemampuan, dan kuesioner kelayakan produk. Data kuantitatif dianalisis menggunakan Skala Likert modifikasi untuk menghitung persentase skor kelayakan. Hasil penelitian menunjukkan bahwa persentase validitas media berdasarkan penilaian ahli materi dan bahasa sebesar 86,9% serta ahli media sebesar 97,5%, yang keduanya termasuk dalam kriteria sangat valid. Pada uji coba lapangan skala kecil, media memperoleh persentase kepraktisan sebesar 100% dari guru dan 89,5% dari peserta didik, sedangkan pada uji coba lapangan skala besar memperoleh persentase sebesar 99,6% dari guru dan 91% dari peserta didik, yang seluruhnya termasuk dalam kriteria sangat praktis. Berdasarkan hasil validasi dan uji kepraktisan tersebut, media pembelajaran interaktif berbasis website dengan pendekatan Contextual Teaching and Learning (CTL) pada materi bilangan rasional memperoleh nilai rata-rata dari seluruh penilaian sebesar 94% dengan kriteria sangat layak, sehingga dapat digunakan sebagai media pembelajaran matematika bagi peserta didik kelas VII SMP. ***** This research and development (R&D) is motivated by the low contextual proble msolving skills and the difficulties faced by grade VII students in understanding the concept of rational numbers at SMPN 21 Bogor, which necessitates innovation in learning media. This study aims to develop website-based interactive learning media using the Contextual Teaching and Learning (CTL) approach for grade VII rational numbers and to determine its feasibility. The research method employed is Research and Development (R&D) utilizing the 4D development model stages, which include define, design, develop, and disseminate. The website-based interactive learning media was developed using Adobe Animate with HTML output to ensure responsiveness across various devices, while integrating the seven components of CTL into a structured learning flow. Data collection was conducted through interview instruments, needs assessment questionnaires, ability tests, and product feasibility questionnaires. Quantitative data were analyzed using a modified Likert Scale to calculate the percentage of feasibility scores. The results showed that the learning media achieved a validity score of 86.9% based on the evaluation of the material and language experts and 97.5% based on the evaluation of the media expert, both of which were categorized as highly valid. In the small scale field trial, the media obtained practicality scores of 100% from the teacher and 89.5% from the students. In the large-scale field trial, the practicality scores were 99.6% from the teacher and 91% from the students, all of which were categorized as highly practical. Based on the validity and practicality results, the interactive website-based learning media employing the Contextual Teaching and Learning (CTL) approach for the topic of rational numbers achieved an overall average score of 94%, indicating that it is highly feasible for use as a mathematics learning medium for seventh-grade junior high school students.
