This study examined changes in fourth-grade students’ learning outcomes after the use of Boards of the Human Bones media in learning about human bone structure and function. A one-group pretest–posttest approach was applied to 22 students of SD Negeri 124392 Pematangsiantar in the 2025/2026 academic year. Learning achievement tests were administered before and after instruction. The Shapiro–Wilk test and paired-samples t-test were used for analysis. Mean scores increased from 40.86 to 80.27, a gain of 39.41 points. The paired test yielded t(21) = −17.067 and p < .001. These findings indicate a statistically significant improvement after the intervention; however, without a control group, the change cannot be attributed exclusively to the media.
