Abstract

Practicum is an important part of the chemistry learning process, providing students with direct experience that helps them think and work scientifically. This research aims to produce a colloid practicum e-module based on STEM-Case Based Learning. The research method used is research and development, employing the Borg&Gall model. The developed practicum e-module was created with Flip PDF Pro and includes an introduction, case studies, material (such as understanding colloid systems, the Tyndall effect, properties of colloids, and making simple colloids), images, videos, and a summative assessment at the end of each chapter. The STEM components of the colloids e-module include: (1) Science, which involves students^ understanding of simple chemicals that can be used in practical work- (2) Technology, which involves producing digital information in the form of practical videos- (3) Engineering, which involves designing and conducting experiments with simple materials- and (4) Mathematics, which involves analyzing and solving problems mathematically. The e-module has been validated by experts, receiving assessments ranging from 70-100% by media and material experts. Small-scale trials received scores ranging from 63-100%, while large-scale trials scored between 75-100%. Based on these results, it can be concluded that the e-module is categorized as good for use in chemistry learning.
