Abstract
This research focuses on creating an electronic student worksheet (E-LKPD) centered around Problem-Based Learning (PBL) through Scratch, aimed at improving students' computational thinking abilities in algebra at Ngadirejo Islamic Junior High School, located in Temanggung Regency. A Research and Development (RandD) method is utilized, following the ADDIE framework (Analysis, Design, Development, Implementation, Evaluation). The subjects of this research were the seventh-grade students in class VII H, and surveys served as the primary data collection tool. Validation outcomes show that the E-LKPD learning material received an average score of 86. 3%, categorizing it as "valid. " Student and teacher feedback also highlighted the E-LKPD's practicality, reflected in a score of 83. 47%. The integration of this resource into mathematics teaching significantly boosted students' computational thinking skills. The average scores climbed from 34. 97 before application to 68. 32 afterward, resulting in an N-gain score of 0. 5342, which is rated as "medium. " Therefore, it can be concluded that the E-LKPD is valid, practical, and effective in enhancing the computational thinking skills of students.
