Validitas E-Modul Berbasis Problem Based Learning pada Materi Perubahan Lingkungan Kelas X SMA/MA

Developments in technology and information affect the management of teaching materials. E-Module is one innovative digital materials that can be used to support learning process. The purpose this research produce a valid E-Module. This was conducted at Department Biology Education, Faculty Science Technology, West Sumatra PGRI University using 4D model (Define, Design, Development, Disseminate). However, only reached development stage. assessment instrument validation sheet. data obtained were analyzed by descriptive quantitative. Based on results from material experts, media teachers, it shows an average score 98.5% which seen feasibility content, language, didactics, graphics. these concluded problem-based learning-based produced very suitable for use as material.
