Abstract

This research was conducted to investigate the influence of instructional models and self-efficacy on the development of kumite technique skills in karate practice. An experimental approach with a 2×2 factorial design was implemented. The instructional model served as the independent variable, comprising Direct Instruction (DI) and the Personalized System for Instruction (PSI), while self-efficacy was treated as a moderating variable. The participants included 32 students involved in a karate extracurricular activity at a public senior high school in Bandung Regency. The assessment of kumite technique performance was carried out using the System for the Technical Assessment of Kumite (STAK). In contrast, students’ self-efficacy levels were measured through the General Self-Efficacy Scale (GSES-12). The collected data were examined using two-way ANOVA. The analysis revealed that the instructional model significantly affected the enhancement of kumite technique skills. Self-efficacy was also found to have a significant impact on the improvement of kumite performance. Moreover, a statistically significant interaction emerged between the instructional model and self-efficacy. These results suggest that the application of Direct Instruction combined with a high level of self-efficacy resulted in the greatest improvement in kumite technique skills.

Abstract

Physical activity has been widely recognized as an important factor supporting children's physical and psychosocial development. School environments provide structured opportunities where such activities can be systematically implemented through physical education programs. Although previous studies have examined the benefits of physical activity, evidence concerning its simultaneous impact on motor competence and life skills development remains scattered. This study aims to synthesize empirical findings regarding the effectiveness of school-based physical activity programs in improving fundamental motor skills and life skills among children and adolescents. A systematic literature review was conducted following the PRISMA procedure using articles obtained from Scopus, ScienceDirect, Google Scholar, ResearchGate, and the Directory of Open Access Journals. After applying inclusion criteria, 17 studies were selected for analysis. The results indicate that structured physical activity interventions consistently improve fundamental motor skills, particularly locomotor and object control abilities. In addition, participation in physical activity programs contributes to the development of life skills such as teamwork, leadership, communication, and self-management. Programs that integrate skill practice, game-based learning, and social interaction demonstrate the most consistent outcomes. These findings suggest that well-designed physical activity programs in schools can support both motor competence and broader developmental outcomes in children.
