Development of Discovery Learning-Based E-LKPD for Linear Equation Material in Class VIII SMP/MTs

This research and development (R&D) aims to produce an electronic Student Worksheet (E-LKPD) on straight-line equation material based on discovery learning that qualifies as valid and practical. This type of research is development research with the 4-D development model (Define, Design, Develop, Disseminate). Data collection instruments involved validation sheets and student response questionnaires. Data analysis techniques used include validity and practicality analysis. The E-LKPD validation results were 89.28% with very valid criteria. E-LKPD testing in small groups resulted in a practicality level of 83.82%, categorized as practical, while testing in the big group reached 82.004%, with practical criteria. The data analysis concluded that the discovery of learning-based E-LKPD on straight-line equation material has complied with the validity and practicality standards. Accordingly, the developed E-LKPD can be used by students in grade VIII.
