Abstract

The low learning outcomes of students in multiplication and division are attributed to the limited use of interactive learning media and the lack of learning motivation. This condition highlights the need for developing innovative media based on Problem Based Learning (PBL) to enhance learning effectiveness and student engagement. This study aims to develop, analyze the feasibility, and examine the effectiveness of the PEKA interactive learning media based on PBL for teaching multiplication and division in elementary education. The research employs a Research and Development (R&D) approach using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). The participants included subject matter experts, instructional design experts, media specialists, and fourth-grade students. The instruments consisted of validation questionnaires and learning achievement tests, while data were analyzed using quantitative descriptive, qualitative descriptive, and inferential statistical methods. The feasibility results indicated that all evaluated aspects achieved scores ranging from 88.89% to 94%, categorized as good to very good. The t-test results showed that tcount > ttable (1.989 > 1.701), indicating a significant improvement in students’ learning outcomes. It can be concluded that the PBL-based PEKA media is feasible and effective in enhancing students’ understanding and learning achievement. The implication suggests that this media can serve as an innovative alternative to foster interactive, contextual, and student-centered mathematics learning while strengthening critical thinking skills.

Abstract

The lack of contextual learning and the use of unengaging media in elementary school mathematics often result in low conceptual understanding and reduced student motivation, especially in multiplication, thus failing to meet the expected competency standards. This study aims to develop, assess the feasibility, and effectiveness of an interactive e-book based on Project Based Learning. This is a research and development (R&D) study using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). The research subjects included experts in product design, subject matter, instructional design, learning media, and 28 fifth-grade students. The instruments used were questionnaires and tests, with data analysis techniques involving quantitative descriptive, qualitative descriptive, and inferential statistics. The feasibility results showed scores ranging from 86.11%-96.60%, classified as good to very good. The t-test showed tcalculated>ttable (10.883>1.703), indicating that H0 was rejected and H1 was accepted. In conclusion, the interactive e-book based on Project Based Learning is proven to be feasible, effective, and capable of improving students’ understanding and learning outcomes. This media can serve as an innovative alternative to support teachers in creating engaging, interactive, and contextual learning.
