This study investigated the effectiveness of a Tokkatsu-based program in enhancing musical creativity and skills among primary school students, with a particular focus on their ability to apply these skills in music classes. A two-group pre-test-post-test experimental design was employed to evaluate the program’s impact. The participants were forty fourth-grade students during the 2023-2024 academic year, with twenty students assigned to the experimental group and twenty to the control group. The experimental group studied music education topics using Tokkatsu activities, while the control group received standard instruction. The program was conducted according to a teacher’s guide specifically designed for implementing Tokkatsu activities in music education, emphasizing experiential learning through rhythm, movement, singing, and practical music exercises. Data were collected using a musical creativity test. The findings revealed statistically significant improvements in both overall musical creativity and its sub-skills, with post-test scores significantly higher than pre-test scores. Furthermore, the program demonstrated substantial effectiveness in improving students’ musical creativity, as evidenced by measurable gains in all sub-skill areas, highlighting its practical and educational value in primary school music instruction. These outcomes underscore the potential of Tokkatsu-based programs and recommend their broader application, as well as future studies to examine long-term benefits and adaptability across diverse educational settings.
