Abstract

The low level of critical thinking skills among students on the subject of inflation and deflation is caused by the use of monotonous printed worksheets that tend to emphasize memorization of definitions and low-level exercises (LOTs). Based on this problem, the researcher wanted to develop interactive HOTS-based E-LKPD that could help students improve their critical thinking skills. The purpose of this study was to determine the feasibility, effectiveness, and practicality of using E-LKPD. This study used the Research and Development (R&D) method and the ADDIE model with a one-group pretest-posttest trial design on 11th grade students. The results of the media expert validation of this study obtained a score of 77% (feasible), and the results of the material expert validation obtained a score of 93% (very feasible). The student response was 86% and triggered an increase in critical thinking skills with an average gain score of 0.5384 (moderate). Therefore, it can be concluded that the E-LKPD Liveworksheets based on Predict-Observe-Explain (POE) is feasible and effective in improving students' critical
