PENGEMBANGAN LKPD DIGITAL BERBANTUAN GEOGEBRA PADA MATERI FUNGSI LINEAR KONTEKS MASALAH SAMPAH UNTUK MENDUKUNG KEMAMPUAN COMPUTATIONAL THINKING SISWA
This study aims to develop GeoGebra-assisted digital worksheets on linear functions using a waste problem context that are valid, practical, and have potential effects on students’ computational thinking skills. The study employed a design research approach of the development studies type, with data collected through questionnaires, tests, and interviews. The validity of the worksheets was evaluated by experts in terms of content, construct, language, and ICT, resulting in an average validity score of 93.81% (highly valid). Practicality was determined from student response questionnaires at the small-group stage, with an average score of 82.18% (practical). The digital worksheets are designed as interactive learning materials implemented via the TopWorksheets platform, oriented toward student activities that begin with problem situations, apply linear functions, and use waste-related contexts as sources of mathematical problems. Learning activities are structured based on computational thinking indicators and supported by embedded GeoGebra. The potential effect of the worksheets is reflected in the increase in students’ average computational thinking scores at SMP Negeri 32 Palembang from 46.03 (pretest) to 71.43 (posttest), supported by the Wilcoxon Signed-Rank Test result (p = 0.000 < 0.05), indicating a significant difference before and after the intervention.
