Pengembangan Bahan Ajar Kimia Berbasis Problem Based Learning untuk Meningkatkan Pemahaman Konsep Peserta Didik
Abstract
This study aims to develop a Problem Based Learning (PBL) based chemistry teaching material that has valid, practical, and effective criteria to enhance students' understanding of the materials of electrolyte and nonelectrolyte solutions. The type of research used is Research and Development (R & D) with 4D design model that modified 3D, consisting of Define, Design, and Develop stages. The results showed that PBL-based chemistry teaching materials that have been developed have valid, practical, and effective criteria in improving students' concept understanding on the material of electrolyte and nonelectrolyte solution.
