PENGEMBANGAN E-LEARNING DENGAN MODEL PEMBELAJARAN KOOPERATIF BERBASIS WEB PADA MATERI KEKONGRUENAN DAN KESEBANGUNAN UNTUK SISWA KELAS IX SMP
Lack of a learning process that is able to stimulate students to practice mathematical problem solving skills by working together (mutual cooperation) which can cause the mathematical abilities of these students have not developed optimally. This study aims to develop of e-learning with a web-based cooperative learning model that is valid for practicing students' mathematical problem solving abilities. This research is a type of Research and Development (R&D) research. Data in research were collected by method MSR (Methode of Summated Rattings). The research instrument used was the expert validation sheet and peers. Data were analyzed with descriptive analysis to measure the validity of web-based cooperative learning media. The results showed that the web-based cooperative learning media fulfilled valid criteria with the dominance of the assessment being in the valid category.
