Abstract

This study aims to describe the implementation of a cooperative learning model assisted by Pop-Up Book media and to analyze the improvement in learning interest and learning outcomes of fourth-grade students on the topic Indonesiaku Kaya Budaya at SDN Lalangon 1. The research employed a Classroom Action Research (CAR) approach conducted in three cycles, each consisting of the stages of planning, implementation, observation, and reflection. The research subjects were the teachers and fourth-grade students of the 2025/2026 academic year. Data were collected through observation, interviews, documentation, and learning achievement tests. The data were analyzed using data reduction, data display, and conclusion drawing techniques, with triangulation applied to ensure validity. The results indicate that the quality of instructional implementation improved consistently in each cycle. The average percentage of teacher activity increased from 80.01% to 98.61%, while student activity increased from 81.02% to 99.17%. Students' learning interest showed a significant improvement, rising from 75.00% in Cycle I to 97.23% in Cycle III. This improvement had a positive impact on learning outcomes, as reflected in the increase of the mean score from 63.08 to 94.03 and the rise in learning mastery, which reached 96% by the end of the final cycle. These findings demonstrate that the integration of a cooperative learning model with Pop-Up Book media is effective in fostering interactive, contextual, and meaningful learning, as well as in optimizing students' cognitive, affective, and social engagement in elementary school settings.
