SANTI RAHAYU DESITANINGSIH: Development of E-LKPD Based on Guided Discovery Learning Assisted by TopWorksheets to Improve Mathematical Conceptual Understanding. Thesis, Ponorogo: Mathematics Education Program, Muhammadiyah University of Ponorogo, 2026.
The purpose of this study is to develop Guided Discovery Learning-based digital worksheetssupported by TopWorksheets that meet the criteria of being valid, practical, and effective in improving the understanding of mathematical concepts among eighth-grade studentsat MTs Muhammadiyah 1 Ponorogo. The development of the E-LKPD was carried out to provide digital teaching materials that facilitate students’ active role in discovering concepts independently, thereby enhancing their understanding of mathematical concepts. The E-LKPD that has been developed is expected to support student-centered learning through a process of conceptual discovery guided by teachers.
This study is a Research and Development (R&D) project using the ADDIE development model, which comprises five stages analysis, design, development, implementation, and evaluation. The research subjects were eighth-grade students at MTs Muhammadiyah 1 Ponorogo. The validity of the product was assessed by subject matter experts and media experts; its practicality was assessed through questionnaires completed by teachers and students and its effectiveness was assessed through a mathematical concept comprehension test.
The research results showed that the Guided Discovery Learning-based E-LKPD supported by TopWorksheet received a validity rating of 87.5% from media experts, falling into the “highly suitable” category, while the validity rating from subject matter experts was 85%, also falling into the “highly suitable” category. The practicality assessment results, based on educator response questionnaires, yielded a percentage of 81,6%, while student responses yielded a percentage of 86.88%; both fall into the “highly practical” category. The effectiveness assessment results indicate that the E-LKPD meets the “effective” criteria, with a student mastery rate of 86.95%. Based on these results, it can be concluded that the E-LKPD based on Guided Discovery Learning supported by TopWorksheet meets the criteria of validity, practicality, and effectiveness, making it suitable for use in mathematics instruction to enhance students’ understanding of mathematical concepts.
