DEVELOPMENT OF ONLINE INTERACTIVE LEARNING MEDIA USING GeoGebra APPLET ON PROBABILITY

This study is intended to determine the feasibility of online interactive learning media using the Geogebra Applet on the probability material developed. The use of the model in this development research is the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The research subjects included mathematics teachers and class VIII B students of Gema Nurani Integrated Islamic Junior High School. The data collection technique used was observation in the form of needs analysis and interviews and questionnaires. The results of the study were obtained based on the percentage of validity test scores by two expert validators including material experts and media experts as well as a questionnaire response from mathematics teachers and students to obtain the feasibility of the developed learning media. Based on the results of the assessment by the material expert validator, the percentage is 94.64% in the very appropriate category and media experts at 73.08% in the appropriate category. While the results of the feasibility of the mathematics teacher response questionnaire showed a percentage of 92.5% with a very decent category and a student response questionnaire of 88.04% with a very decent category. Thus, the use of the Geogebra Applet in the probability material is very feasible to be applied as an online interactive learning medium in class VIII.Penelitian ini dimaksudkan untuk mengetahui kelayakan media pembelajaran interaktif online menggunakan Applet Geogebra pada materi peluang yang dikembangkan. Penggunaan model dalam penelitian pengembangan ini yakni model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian antara lain guru matematika dan siswa kelas VIII B SMP IT Gema Nurani. Teknik pengambilan data yang dilakukan yakni observasi berupa analisis kebutuhan dan wawancara serta angket. Hasil penelitian diperoleh berdasarkan persentase penskoran uji validitas oleh 2 validator ahli diantaranya ahli materi dan ahli media serta angket respon guru matematika dan siswa untuk memperoleh kelayakan dari media pembelajaran yang dikembangkan. Berdasarkan hasil penilaian oleh validator ahli materi menunjukkan persentase sebesar 94.64% dengan kategori sangat layak dan ahli media sebesar 73.08% dengan kategori layak. Sedangkan hasil kelayakan dari angket respon guru matematika menunjukkan persentase sebesar 92.5% dengan kategori sangat layak dan angket respon siswa sebesar 88.04% dengan kategori sangat layak. Dengan demikian, penggunaan Applet Geogebra pada materi peluang sangat layak diaplikasikan sebagai media pembelajaran interaktif online di kelas VIII
