Abstract

Collaboration skills and critical thinking abilities are essential 21st-century skills needed in both education and daily life. This Research and Development study aims to develop a problem-based learning LKPD (Student Worksheet) that is valid, practical, and effective. The LKPD was developed to enhance students' collaboration skills and critical thinking abilities using the ADDIE model (Analyze, Design, Development, Implementation, and Evaluation). The subjects of this study were the eighth-grade students of SMPN 7 Menui Satap. The results showed that the developed LKPD was highly valid, with validity scores of 95% from Validator 1 and 92.14% from Validator 2. It was also very practical, with a practicality score of 95.5%. Furthermore, it was moderately effective in improving collaboration skills, with an average score of (M= 78.25%), and highly effective in enhancing critical thinking abilities from 43 to 81 and Cohen’s d=0.88, categorized as a huge effect.
