Abstract

This study aims to develop TAPENA media (Equivalent Fraction Table) based on the 4D model to improve the understanding of fraction concepts among fourth-grade students at SDN 1 Made Lamongan. The research employed the Research and Development (R&D) method using the 4D model (Define, Design, Develop, Disseminate). The research subjects were 28 fourth-grade students. Data were collected through observations, tests, and questionnaires. The results showed that after material explanation without media, only 5 students (17.86%) understood the concept, whereas after using TAPENA media, all 28 students (100%) understood the concept of equivalent fractions. TAPENA media presents a table that makes it easier for students to see the relationship between fractions visually. The media validity from material experts reached 86.5% (very valid), and from media experts 88.2% (very valid). The practicality test by teachers obtained 90.5%, and by students 94.8%. These findings prove that TAPENA media is valid, practical, and effective in improving the understanding of fraction concepts. The implication is that TAPENA media can be used as an innovation in mathematics learning in elementary schools. It is recommended that teachers integrate TAPENA into learning activities to motivate students.
