Abstract

This study aims to describe the validity, practicality, and effectiveness of Student Worksheets (LKPD) based on Higher Order Thinking Skills (HOTS) on pressure material using a problem-based learning model at SMP Negeri 1 Menui. The research method is a type of development research following the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects of the study were class VIII A students, consisting of 12 boys and 13 girls with the average age was 15 years old. Data collection involved validation sheets, questionnaires, and written tests. Validation sheets were used to assess the validity of the developed learning tools. Questionnaires evaluated the practicality of the learning tools, while written tests measured students' scientific process skills before and after the implementation of HOTS learning tools. The results showed that the developed LKPD is categorized as good, with an average validation percentage of 78.93%, classified as valid. The teacher response score of M=3.78 classified it as practical. Field testing indicated that the LKPD effectively improved students' critical thinking and scientific process skills. This was evidenced by scientific process skills score of M= 77.46, categorized as effective. Additionally, the pre-test and post-test results showed an increase score from M=64 to M=73, with an Cohen’s (d= 0.98) categorized as huge effect.
