Development and Feasibility Evaluation of an Interactive E-LKPD Based on Contextual Teaching and Learning for Grade VIII Science Learning

Abstract

This study aimed to develop an E-LKPD using the CTL approach for Grade VIII science learning at SMP Negeri 14 Palembang. The study also employed a R&D design using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. Formative evaluation was conducted through expert validation, one-to-one evaluation, small-group evaluation, and field testing. Data were collected through observation, interviews, expert validation questionnaires, and student response questionnaires and analyzed descriptively using percentage-based qualification criteria. The developed E-LKPD integrated the seven CTL components with contextual learning activities, multimedia, interactive quizzes, evaluation, and reflection. Expert validation resulted in scores of 86.06% for subject matter, 83.37% for instructional design, and 83.40% for media. Student evaluations produced scores of 87.23% in the one-to-one evaluation, 86.01% in the small-group evaluation, and 89.31% in the field test. These findings indicate that the developed E-LKPD is highly feasible and positively accepted as a digital learning resource for contextual and student-centered science learning. However, the findings establish feasibility and usability rather than causal learning effectiveness.
