Introduction. The problem and the aim of the study. Although the 2022 South Korean national curriculum revision emphasizes digital competencies and education for sustainable development (ESD), there is a lack of empirically validated programs that integrate these components in secondary education. This study aims develop and evaluate an innovative educational program that leverages realistic Edutech to promote sustainable consumption among high school students in South Korea.
Research methods. The participants consisted of a total of 87 students, with 50 assigned to the experimental group and 37 to the control group. Surveys measuring sustainable consumption behavior and consumer citizenship competency were administered to all participants. For data analysis, SPSS Win Version 21.0 was used. A t-test was conducted to verify the homogeneity between the experimental and control groups. To evaluate the effectiveness of the program, ANCOVA (Analysis of Covariance) and paired t-tests were performed on both groups.
Results. To evaluate the effectiveness of the program, an analysis of covariance (ANCOVA) was conducted using pre-test scores as covariates to compare post-test scores between the experimental and control groups. After controlling for pre-intervention scores on sustainable consumption behavior, the estimated post-test mean was 4.009 for the experimental group and 3.611 for the control group, showing a statistically significant difference (F = 7.747, p < .01). A comparison of pre- and post-test scores also confirmed the program’s effectiveness. In the experimental group, sustainable consumption behavior significantly improved from 3.204 to 3.939 (p < .001), while the control group showed a smaller but statistically significant increase from 3.464 to 3.706 (p < .05). Regarding consumer citizenship competency, the experimental group showed a significant improvement from 3.160 to 3.460 (p < .001), whereas the control group’s score slightly decreased from 3.730 to 3.622, which was not statistically significant (p > .05).
Conclusion. These results suggest that the Realistic Edutech-based Sustainable Consumption Education Program had a positive effect on both sustainable consumption behavior and consumer citizenship competency among female high school students.
