the impact of interactive micro-video–based learning on elementary students' knowledge, attitudes, and skills in personal health education

Background: teaching health and self-care during childhood is essential for promoting long-term well-being. as digital education becomes more prevalent, interactive micro-videos have shown potential as an engaging tool to improve students' health knowledge and literacy. this study aimed to evaluate the effectiveness of interactive micro-video–based instruction on elementary students' knowledge, attitudes, and personal health skills.methods: a quasi-experimental study employing a pre-test post-test design with a control group was carried out from september 2022 to january 2023 in a boys' elementary school located in tehran, iran. thirty-eight 6th grade students were randomly assigned to either an intervention group (n=19), receiving six sessions of personal health education via interactive micro-videos, or a control group (n=19), receiving conventional instruction. a researcher-developed 40-item questionnaire was validated through expert review (cvi = 0.85) and reliability testing (cronbach's α = 0.74–0.90). data were analyzed using spss v.22, including descriptive statistics, independent and paired samples t-tests, and non-parametric alternatives (mann–whitney u and wilcoxon signed-rank tests) where appropriate.results: baseline comparisons showed no significant differences between groups in age or access to digital devices. post-intervention analysis revealed significant improvements in the intervention group in knowledge and personal health skills (p<0.001), while changes in attitude were not statistically significant. gain scores confirmed a strong effect of the micro-video intervention, particularly in knowledge acquisition.conclusion: interactive micro-video instruction significantly enhanced students' health-related knowledge and skills. the integration of multimedia design principles offers a scalable and effective strategy for school-based health education, especially in contexts requiring flexible and engaging learning formats.
