Pengembangan E-LKPD Berbantuan Liveworksheets untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa SMP

Abstract

The integration of digital media in mathematics education is essential to address the challenges of developing students’ problem-solving abilities in the twenty-first century. This study aims to develop and evaluate the effectiveness of an electronic student worksheet (E-LKPD) assisted by Liveworksheets to enhance mathematical problem-solving skills among junior high school students, specifically in the context of linear equation systems in two variables. The research employed a research and development approach utilizing the ADDIE model, encompassing analysis, design, development, implementation, and evaluation stages. The E-LKPD was systematically validated by media and content experts, revised accordingly, and implemented through small and large group trials involving eighth-grade students at a public junior high school. The findings indicate that the developed E-LKPD is highly feasible, as evidenced by expert validation results, and is well received by students, who reported increased engagement, understanding, and motivation. Effectiveness was quantitatively assessed through pretest and posttest measures of mathematical problem-solving skills, revealing a substantial improvement after using the E-LKPD. The results demonstrate that the integration of interactive features, multimedia content, and structured problem-solving indicators within the E-LKPD significantly enhances students’ ability to understand and solve mathematical problems. This research underscores the importance of innovative digital learning resources in fostering active, student-centered learning environments and provides practical implications for educators and curriculum developers aiming to optimize mathematics instruction in the digital era..
