E-Module Development of Problem-Based Learning Electrical Materials Courses

This research is based on the problem of modules used by lecturers in Electrical Materials Science courses who are still not able to encourage students to be able to study independently because the modules used have not directed students to be able to find learning concepts and the material in the module does not fully cover every competency. The syllabus is applied based on the curriculum. The material presented by the lecturer in the regulatory system course at the Faculty of Engineering, Padang State University, has not been fully understood by students. This is because the material is not conceptual, and also less interactive so sometimes students feel bored and do not have the motivation to study independently after or before learning. This has an impact on the one-way learning system, where students only expect explanations from the lecturer. This study aims to produce an E-Module for Electrical Materials Science courses that are valid, practical, and effective. This study used development research methods using a 4D model, namely define, design, development, and dissemination. While the subjects in this study were students of Electrical Engineering, Padang State University. The subjects of the research were students of the Faculty of Engineering, Department of Electrical Engineering. The research instrument is a validity questionnaire, a practicality questionnaire, and a test. The results of the study obtained the validity of the E-Module data from material experts and media experts with valid categories. Practical test with the lecturer and student respondents obtained E-Module learning Electrical Materials Science is included in the very practical category. Test the effectiveness of the E-Module in Electrical Materials Science through the results of the post-test. Students obtained that the E-module is in the effective category.
