Chemistry education in high school often faces challenges in conveying abstract materials such as colloids to students during learning activities. This study aims to develop an e-module for colloid material based on Problem Based Learning (PBL) to help students understand abstract materials such as colloids. This has been proven through several previous studies that developed e-modules on several other abstract materials and proved effective. Therefore, this e-module has the potential to help students understand colloid material.]]>
