Abstract

Computational thinking skills among junior high school students generally remain low, while teachers seldom combine digital learning media with local culture in mathematics lessons. An ethnomathematics-based Scratch medium offers one way to close this gap, since it makes mathematics learning more contextual, engaging, and meaningful. This study set out to build such a medium and examine whether it meets standards of validity, practicality, and effectiveness for strengthening students' computational thinking. A research and development (R&D) design was applied, following the five ADDIE stages analysis, design, development, implementation, and evaluation with eighth-grade students at SMP Negeri 1 Pragaan as participants. Data were gathered through a validation sheet, response questionnaires from teachers and students, and pretest-posttest scores, then examined descriptively alongside the N-Gain formula. The resulting media obtained a validity score of 80%-85.5% (valid), a practicality score of 75% (fairly practical), and an N-Gain of 69% in the experimental class versus 33% in the control class (fairly effective). Overall, these results suggest that ethnomathematics-based Scratch media can support junior high school students in building stronger computational thinking skills.
