Development of Indonesian History Exploration Suitcase to Enhance Fifth- Grade Students Understanding of Cultural Heritage

Cultural heritage learning in elementary schools should not merely emphasize memorizing cultural names but should enable students to connect cultural heritage with its geographical origin, historical context, function, and meaning. This study aimed to develop a feasible Koper Jelajah Sejarah Indonesia learning medium and analyze the improvement in fifth-grade students’ understanding of cultural heritage after using the medium. The study employed Research and Development using the ADDIE model involving analysis, design, development, implementation, and evaluation. Twenty-seven fifth-grade students of MI Al Ma’arif Ma’sum Jepon participated in the implementation, while three validators consisting of one lecturer and two teachers assessed the product. Data were collected through observation, teacher interviews, media validation sheets, and a 40-item multiple-choice cultural heritage comprehension test. The validation yielded an average score of 58 out of 75, or 77.33%, and all validators concluded that the medium was feasible for use with revisions. The mean pretest score increased from 77.85 to 88.43 in the posttest. The paired-samples t-test showed a significant difference, t(26) = 8.67, p < .001, while the normalized gain of 0.48 indicated a moderate improvement. These findings demonstrate an improvement in students’ cultural heritage comprehension after using the developed medium.
