Contextual Mobile Learning in Physics: Egrang-Based Digital Worksheets for Developing Critical Thinking Skills

This study analyzes the effectiveness of an Electronic Student Worksheet (E-LKPD) integrated with the local wisdom of the traditional egrang game in enhancing students’ critical thinking skills in physics learning. The E-LKPD was developed using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate) and tested with a one-group pretest–posttest design involving 35 students in Class XI A3. Effectiveness was measured through normalized gain (N-Gain) analysis of students’ critical thinking test scores. Results showed an average N-Gain of 0.81 (high category), with 97% of students achieving substantial improvement. Integrating the egrang game as a contextual learning medium helped students link real-life experiences with physics concepts, fostering deeper understanding and active engagement. These findings indicate that the developed E-LKPD effectively improves critical thinking skills while supporting meaningful, culturally relevant, and student-centered learning aligned with 21st-century educational demands.
