Abstract
Results from international assessments and previous studies indicate that students’ numeracy skills remain low, particularly in understanding trigonometric ratios and applying them to real-life situations. Computational Thinking (CT) has the potential to support numeracy skills by enabling students to solve problems logically, systematically, and efficiently. This condition is attributed to limited learning innovation. In addition, the integration of Palembang local wisdom contexts can make learning more meaningful by connecting mathematical concepts to students’ real-life experiences. This study aims to develop digital worksheet for trigonometry based on CT with Palembang local wisdom that is valid, practical, and effective in enhancing numeracy. Using design research method with development studies type, the stages consisted of preliminary research, development/prototyping, and assessment. The subjects were 34 tenth-grade students from one of the Madrasah Aliyah Negeri (MAN) in Palembang. Data were collected through validity and practicality questionnaires, as well as pretests and posttests. Results showed a validity score of 94% (very valid) and practicality of 92% (very practical). Moreover, the Wilcoxon Signed-Rank Test revealed a significant difference between students’ pretest and posttest numeracy scores (Asymp. Sig. = 0.000 < 0.05), indicating that the worksheet effectively supports students’ numeracy skills. Thus, the developed digital worksheets are valid, practical, and effective. Future research may test this on larger samples to verify consistency of results. Abstrak Hasil asesmen internasional dan penelitian terdahulu menunjukkan bahwa kemampuan numerasi peserta didik masih rendah, terutama dalam memahami perbandingan trigonometri dan menerapkannya pada kehidupan nyata. Kondisi ini disebabkan oleh terbatasnya inovasi pembelajaran. Computational Thinking (CT) berpotensi mendukung kemampuan numerasi dengan membantu peserta didik menyelesaikan masalah secara logis, sistematis, dan efisien. Selain itu, integrasi konteks kearifan lokal Palembang dapat membuat pembelajaran lebih bermakna dengan menghubungkan konsep matematika pada pengalaman nyata peserta didik. Penelitian ini bertujuan mengembangkan LKPD digital trigonometri berbasis CT dengan konteks kearifan lokal Palembang yang valid, praktis, dan efektif dalam mendukung kemampuan numerasi. Penelitian ini menggunakan metode design research jenis development studies dengan tahapan preliminary research, development/prototyping, dan assessment. Subjek penelitian ini adalah 34 peserta didik kelas X di salah satu Madrasah Aliyah Negeri (MAN) di Palembang. Data dikumpulkan melalui angket validitas dan kepraktisan, serta pretest dan posttest. Hasil penelitian menunjukkan bahwa LKPD digital yang dikembangkan memperoleh skor validitas sebesar 94% (sangat valid) dan kepraktisan sebesar 92% (sangat praktis). Selain itu, hasil uji Wilcoxon Signed-Rank menunjukkan adanya perbedaan yang signifikan antara skor pretest dan posttest kemampuan numerasi peserta didik (Asymp. Sig. = 0,000 < 0,05), mengindikasikan bahwa LKPD tersebut efektif dalam mendukung kemampuan numerasi peserta didik. Dengan demikian, LKPD digital yang dikembangkan terbukti valid, praktis, dan efektif. Penelitian selanjutnya dapat mengkaji penerapan LKPD digital ini pada subjek yang lebih banyak untuk melihat konsistensi hasil.
