Development of Discovery Learning-Based E-LKPD to Enhance Students' Learning Motivation and Achieve Critical Thinking Skills in Salt Hydrolysis Material

This study aims to evaluate the viability, practicality, and effectiveness of based on discovery learning (E-LKPD) in raising students' motivation to learn and cultivating their critical thinking abilities (CTS). This study adopts a quantitative methodology by utilizing the research and development (R&D) technique and the Borg and Gall model. Sixty-two students from SMA Negeri 1 Baitussalam's class XI make up the study sample. The average results of the viability test for the E-LKPD, reviewed from the aspects of material completeness, accuracy, currency, and alignment with objectives, obtained a percentage of 91.25% with the criterion of "very feasible." Meanwhile, the practicality of the E-LKPD based on the responses from students and teachers achieved average percentages of 87.38% and 82.5%, respectively, with the criterion of "very practical." The effectiveness assessment of the E-LKPD, based on non-test results of learning motivation with an N-Gain percentage of 0.56 and the students' CTS test results with a completeness percentage of 79.48, falls under the criterion of "quite effective." Therefore, it can be concluded that this discovery learning-based E-LKPD is viability, practicality, and effectiveness in enhancing learning motivation and achieving students' critical thinking skills (CTS).
