Abstract

The purpose of this research is to determine the effect of using the Let’s Read media on reading comprehension skills among fourth-grade students in the Indonesian Language subject at SDN 101777 Saentis for the 2025/2026 academic year. This study uses a quantitative approach with a quasi-experimental design method, specifically a non-equivalent control group design. The population in this study consists of all fourth-grade students divided into two classes, namely class IV-A as the experimental class and class IV-B as the control class, each with 16 students, resulting in a total sample of 32 students. The research instrument used was a test in the form of essay questions consisting of 10 questions for the pre-test and 10 questions for the post-test. The results of the data analysis showed that the average post-test score of the experimental class was 85, higher than the control class at 68.75. Based on the t-test results, the calculated tvalue was 5.439 and the  ttable Value was 2.042 at a significance level (Sig.) of 0.05, thus H0 was rejected and Ha was accepted. Thus, it can be concluded that the use of the Let’s Read media has a significant effect on the reading comprehension ability of fourth-grade students in the Indonesian language subject, narrative text material, at SDN 101777 Saentis for the 2025/2026 academic year.

Abstract

Science and Social Studies learning in elementary schools still relies heavily on textbooks and printed worksheets, resulting in students who tend to be less active and less motivated in the learning process. This study aims to develop an Electronic Student Worksheet (E-LKPD) based on Project Based Learning (PjBL) on the topic of magnetic force in IPAS subject for fifth-grade students, and to examine its validity, practicality, and effectiveness as a learning medium. This study employed a Research and Development (R&D) approach using the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The research subjects were 20 fifth-grade students at UPT SDN 064994 Medan. Data collection instruments included expert validation questionnaires, teacher and student response questionnaires, and multiple-choice tests in the form of pretest and posttest. Data were analyzed using validity and practicality percentage formulas, as well as the N-Gain formula to measure effectiveness. The results showed that the developed E-LKPD achieved an average expert validation percentage of 93% in the very valid category, an average practicality score of 92.3% from teachers and students in the very practical category, and an N-Gain value of 0.66 in the medium category, which is declared effective. Therefore, the PjBL-based E-LKPD developed is suitable for use as an interactive and contextual IPAS learning medium in fifth-grade elementary school.
