Redox reactions and electrolysis are complex chemistry topics that require teaching materials capable of connecting chemical concepts with contextual chemical phenomena. This study aimed to develop a PjBL-STEM-based general chemistry teaching module integrating an electroplating experiment for redox and electrolysis topics and to determine its validity and practicality. This study employed a Research and Development (R&D) approach using a modified 4D model consisting of three stages: define, design, and develop. Data were collected using validation questionnaires administered to subject-matter and media experts, as well as a student response questionnaire. The validation data were analyzed using Aiken’s V, while the student responses were analyzed based on the practicality percentage. The results showed that the Aiken’s V values obtained from the subject-matter and media experts were 0.903 and 0.874, respectively, both of which were categorized as high validity. The practicality assessment yielded an overall percentage of 87.5%, categorized as very practical. Therefore, the developed module is suitable for use as supplementary teaching material in General Chemistry learning on redox and electrolysis topics.
