Abstract

This study aims to: (1) Determine the validity of case method-based STEM e-modules on carbon and silicon materials; (2) Describe students' responses to case method-based STEM e-modules on carbon and silicon materials; (3) Describe chemistry teachers' responses to case method-based STEM e-modules on carbon and silicon materials. The population in this study were all chemistry teachers at State Senior High School 1 Kisaran (SMA Negeri 1 Kisaran), all chemistry lecturers at Medan State University, all computer science lecturers at Medan State University, all PTIK lecturers at Medan State University and all students in class XII IPA High School. The samples selected in this study were three Unimed chemistry lecturers, one computer science lecturer, one information and communication technology lecturer, and two chemistry teachers at State Senior High School 1 Kisaran as well as responses by 36 students in class XII IPA 5. The development model used was the ADDIE model. The instruments used were interview sheets, needs analysis questionnaires, teaching material analysis sheets, e-module validation sheets based on BSNP, student response questionnaires, and chemistry teacher response questionnaires. The results showed that (1) The case method-based STEM e-module on carbon and silicon material was declared "very valid" with an average percentage of material experts of 93.17% and media experts of 94.39%; (2) The response of students in class XII IPA 5 SMA Negeri 1 Kisaran to the developed e-module was categorized as "very practical" with an average percentage of 87.54%; (3) The chemistry teacher's response to the developed e-module was categorized as "very practical" with an average percentage of 97.39%..
