The Effect of Using CLO3D Software on Developing the Fashion Design Skills of Undergraduate Students at the University of Jeddah

Abstract

This study aims to investigate the effectiveness of using the CLO3D program in developing fashion design skills among undergraduate students at the University of Jeddah. The researcher employed a quasi-experimental method, conducting the experiment on a sample of (24) students during the academic year 2025 / 1446 within the course "Electronic Design," using a one-group design.

To implement the experiment, a digital instructional book was prepared, where students relied on self-directed learning, while the researcher’s role was limited to guidance and supervision through observation checklists. Pre- and post-tests were applied to the same group to measure the changes in both cognitive and practical skills.

The results showed statistically significant differences at the level (p ≤ 0.05) between the pre-test and post-test mean scores in favor of the post-test, both in the achievement test and in the observation checklist of practical skills. Moreover, the effect size measures (Cohen’s d) and Eta-squared indicated a very strong impact of the program on developing students’ cognitive and practical skills.

These findings highlight that the use of CLO3D resulted in a significant improvement in students’ performance, confirming the effectiveness of integrating modern digital technologies into educational curricula. Furthermore, the program contributed to enhancing students’ professional competence and increasing their readiness for the labor market in the field of fashion design.
