Efektivitas Scaffolding Adaptif Berbasis Google Workspace untuk Kemampuan Pecahan dan Motivasi Siswa Sekolah Dasar

Abstract

This study developed and evaluated an Adaptive Scaffolding Application based on Google Workspace for mathematics instruction in elementary schools. The application was designed to improve fifth-grade students' ability to solve fraction word problems and enhance their learning motivation. The study employed a Research and Development (R&D) approach using the ADDIE model, followed by a quasi-experimental design with a pretest–posttest control group. The participants consisted of 24 fifth-grade students from two different elementary schools. Validation by subject matter experts, media experts, and classroom teachers indicated that the application achieved a "Highly Valid" rating, with an average score of 4.57 out of 5. Practicality testing conducted by teachers and students classified the application as "Highly Practical," with a combined score of 85%. Effectiveness testing using SPSS 26 statistical analysis demonstrated that the application significantly improved students' cognitive performance in solving fraction word problems (p = 0.007; Cohen's d = 1.21). However, although a positive practical impact on students' learning motivation was observed, the improvement was not statistically significant (p = 0.293). Overall, the findings indicate that the Adaptive Scaffolding Application is valid, practical, and effective in enhancing elementary school students' mathematics learning outcomes.
