Pengembangan Media Pembelajaran Berbasis Website Berbantuan Geogebra untuk Meningkatkan Hasil Belajar Siswa pada Materi Geometri

Abstract

The use of media in the learning process greatly affects students' learning outcomes. Geogebra can visualize geometric concepts as a learning medium. This research aims to develop a website-based learning media assisted by Geogebra to improve student learning outcomes on geometry material, specifically parallel lines and angles for the 8th grade at SMPN 2 Kuripan, which is valid and practical. The method used is research and development (R&D) with the 4D model developed by Thiagarajan, which includes the define stage, design stage, develop stage, and disseminate stage. The results from the questionnaires, interviews, and post-test learning outcomes were analyzed for validity, practicality, and effectiveness. The research results show that the developed media (1) is valid with very valid criteria; (2) practical with very practical criteria; (3) the learning outcomes of students using the Geogebra website are better than those of students who do not use the website as a medium. Based on the research, it can be said that the developed media is valid, practical, and effective in improving students' learning outcomes.
