Abstract

The COVID-19 pandemic has transformed education into online learning. The main obstacles to online learning are difficulties in internet access and lack of teacher guidance. Most teachers only assign assignments to students by using books as the main medium in online learning. This can make students bored with the appearance of the book. So that the enthusiasm for learning is reduced. Therefore, researchers developed E-Magmath (Electronic Magazine Mathematics) learning media: Flipbook-based Interactive Electronic Magazine on Sets Material in VII SMP / MTs. The purpose of this research is to develop E-Magmath and to find out student responses in learning after using the media developed. This development research uses the ADDIE method which consists of five stages, namely Analyze, Design, Development, Implementation, and Evaluation.
