Abstract

Rendahnya pemahaman peserta didik di SMP Negeri 92 Jakarta pada materi garis dan sudut serta penggunaan media pembelajaran yang belum mendukung visualisasi konsep secara optimal menunjukkan perlunya inovasi media pembelajaran. Penelitian ini bertujuan untuk mengembangkan e-modul materi garis dan sudut berbantuan GeoGebra dengan pendekatan CTL serta menentukan kelayakannya berdasarkan aspek validitas dan kepraktisan. Penelitian ini menggunakan metode Research and Development dengan model pengembangan 4D. Subjek penelitian meliputi validator instrumen, ahli media, ahli materi dan bahasa, guru matematika, serta peserta didik kelas VII dan VIII. Teknik pengumpulan data dilakukan melalui wawancara, angket, dan kuesioner. Berdasarkan hasil penelitian disimpulkan bahwa: (1) E-modul dikembangkan melalui tahapan define, design, develop, dan disseminate; (2) Hasil penilaian kelayakan berdasarkan aspek validitas dan kepraktisan menunjukkan bahwa validasi ahli materi dan bahasa memperoleh persentase 92,25%, validasi ahli media 97,09%, uji coba skala kecil kepada guru 94% dan peserta didik 90%, serta uji coba skala besar kepada guru 96% dan peserta didik 97%. Secara keseluruhan, e-modul memperoleh rata-rata persentase sebesar 94,39%. Berdasarkan hasil tersebut, e-modul dinyatakan layak digunakan dalam pembelajaran. ***** The low understanding of students at SMP Negeri 92 Jakarta on line and angle materials and the use of learning media that have not supported the visualization of concepts optimally shows the need for learning media innovation. This study aimed to develop an e-module on lines and angles assisted by GeoGebra using the CTL approach and to determine its feasibility based on validity and practicality aspects. This research uses the Research and Development method with a 4D development model. Data collection techniques were carried out through interviews and questionnaires. Based on the results of the study, it is concluded that: (1) E-modules are developed through the define, design, develop, and disseminate stage. (2) The feasibility assessment based on validity and practicality aspects showed that the material and language expert validation score was 92.25%, the media expert validation score was 97.09%, the small-scale trial scores were 94% from teachers and 90% from students, while the large-scale trial scores were 96% from teachers and 97% from students. Overall, the e-module obtained an average score of 94.39%. Based on these results, the e-module was declared feasible for use in mathematics learning.
