Abstract

Conceptual understanding can be achieved through digital teaching materials, which can make teaching and learning activities more efficient and imaginative. Therefore, this study aims to develop a digital LKPD on relations and functions to enhance students' mathematical conceptual understanding and to determine its validity and practicality. This research is a Research and Development (R&D) study using the ADDIE development model. The study's subjects were students in class VIII C at SMPN 1 Kabawetan. The research instruments consisted of validation sheets, assessed by material and media experts, and student response questionnaires. The results showed that the developed digital LKPD received a valid category from material experts (average score of 0,75) and a highly valid category from media experts (average score of 0,81). Meanwhile, a limited trial produced an average result of 80%, indicating a practical category. Thus, the developed digital LKPD is feasible and practical for use in school mathematics instruction.
