E-Module Based on LI-PRO-GP Learning Model to Improve Students’ Conceptual Understanding and Problem-Solving Abilities in Science Learning

Understanding concepts and solving problems is one of the essential abilities that students must master. To empower this ability, teaching materials that meet the characteristics of 21st-century learning are needed, including the electronic LI-PRO-GP learning model module. The LI-PRO-GP learning model is one of the learning models that elaborates project learning with literacy and character. Involving literacy and character components in project learning is what distinguishes this learning model from project learning models in general. This study aimed to develop a feasible, practical, and effective LI-PRO-GP learning model e-module to improve students’ conceptual understanding and problem-solving skills. The research employed a Development Research method using ADDIE design framework. The research was conducted from July 2023 to September 2024 in junior high school in Malang City. The subjects of this study included four experts for the feasibility test, two teachers and 34 Grade students for the practicality test, and 27 Grade VIII students for the effectiveness test. Non-test data to assess the e-module’s feasibility and practicality were collected using expert and practitioner assessment instruments. Test data for evaluating conceptual understanding and problem-solving skills were obtained through valid and reliable multiple-choice and essay questions. Descriptive analysis was used to interpret feasibility and practicality data, while paired sample t-tests were conducted to determine the e-module’s effectiveness. The findings indicated that the developed LI-PRO-GP learning mdel e-module is both feasible and practical as a teaching material for vibration and wave topics. Moreover, the paired sample t-test results demonstrated that learning with the L
