Development of E-LKPD Mathematics Project-Based Learning to Increase the Creativity of Junior High School Students

This study aims to develop a mathematics learning media in the form of an E-LKPD based on the Project Based Learning (PjBL) model to enhance junior high school students' creativity. The research employed a Research and Development (R&D) method using a modified 4D development model up to the Develop stage. The research subjects were 20 seventh-grade students at SMP Muhammadiyah 1 Tuban. The instruments included validation sheets by experts, student response questionnaires, lesson implementation observation sheets, as well as pre-tests and post-tests. The validation results by material experts showed 81% (very valid), media experts 80% (valid), and test item validation 87% (very valid). The practicality was indicated by lesson implementation observations at 92.1% and student responses at 86.6%, categorized as very practical. The effectiveness test using N-gain resulted in a score of 0.547, which is in the medium category. Therefore, the developed E-LKPD is valid, practical, and effective in enhancing students’ creativity.
