Abstract

This study aims to develop a digital LKPD based on problem-based learning and culturally responsive teaching in the context of colloid materials, with the intention of improving students' 21st-century skills, particularly their critical and creative thinking abilities. The product was developed by incorporating local Riau Malay wisdom into the context of colloid material learning. The research method used was R&D with the 4D model. Data collection techniques included validity testing by subject and media experts, practicality testing by teachers and students, and effectiveness testing through pre- and post-tests with Class XI-2 students at SMA Negeri 1 Keritang. The validation results indicated that the digital worksheets are highly suitable for use, with validity scores of 93.75% and 95.44%, respectively, from subject matter and media experts. The practicality test obtained a score of 98.6%, while student readability scored 87.5%. The effectiveness tests showed significant increases in critical and creative thinking skills, with N-Gains of 0.76 and 0.77 respectively in the high category. Student responses were 90.31% in the very good category. This study suggests that integrating the PBL and CRT approaches into digital LKPD is an innovative and effective way to improve the quality of 21st-century learning, making it more meaningful and contextual while preserving local wisdom.
