Consistent Improvement in Awareness of Violence Prevention Among Computer Science and Nutrition Students Following Digital Indonesian Language Instruction Based on Outcome-Based Education

Abstract

Integrating the prevention and management of violence into required university-level coursework requires evidence that the benefits of such learning extend beyond a single disciplinary context. This study aims to analyze the consistency of changes in students’ understanding of violence prevention and response among undergraduate students in Computer Science and Nutrition following the use of an Outcome-Based Education digital Indonesian-language textbook. The study employed quantitative secondary analysis of 66 pairs of pre- and post-test scores comprising 15 Computer Science students and 51 Nutrition students. The instrument consisted of a knowledge test with a score range of 0 to 10. Changes within groups were tested using the Wilcoxon signed-rank test. In contrast, differences in changes between groups were tested using the Mann-Whitney U test, Fisher’s exact test, and ANCOVA sensitivity analysis with robust standard errors. Scores increased significantly among Computer Science students from 5.87 to 7.87 (Z = −2.92; p = 0.003) and among Nutrition students from 6.25 to 8.61 (Z = −6.09; p < 0.001). The average increase for each group was 2.00 and 2.35 points, respectively. The difference in score increases between the groups was not significant (U = 432.00; p = 0.446; Cliff’s delta = 0.129). After controlling for baseline scores, the academic program was also not significantly associated with post-test scores (b = 0.638; p = 0.231). A total of 52 of 66 students showed an increase in scores, with no decreases. The findings indicate a pattern of improvement in both disciplines. However, they do not yet demonstrate equivalence of effects because the group sizes were unequal and the study did not include a control group. The novelty of this study lies in testing the cross-disciplinary applicability of campus safety literacy integrated into language learning.
