Abstract

This study aims to apply a syntax-based learning model using the umbrella model approach to enhance students’ cognitive learning outcomes in volleyball material. The research was conducted through two stages: a limited trial and an expanded trial. The limited trial was carried out in Class E, Semester II, involving 20 students. After revisions and improvements, the expanded trial was conducted in Class A, Semester II, with 40 students. Both trials used a one-group pretest-posttest design, and data analysis employed the Shapiro-Wilk test using SPSS Version 25. The results showed that the control class obtained an average cognitive score of 30.03 (47.50%) with a standard deviation of 1.54, while the experimental class achieved an average score of 35.02 (50.00%) with a standard deviation of 1.714. Statistical testing at a 95% confidence level revealed a significance value of 0.00 (<0.05), indicating that Ho was rejected. This means there was a significant difference between students taught using conventional methods and those taught using the syntax learning model based on the umbrella model. Thus, it can be concluded that the application of the umbrella model-based syntax learning model effectively improves students’ cognitive learning outcomes in volleyball material. The model encourages active learning, structured understanding, and better mastery of cognitive concepts compared to traditional teaching methods.

Abstract

Background Problems: Small-sided games (SSGs) have become a significant focus of research in the context of team sports, and a thorough review and analysis of the existing research landscape is needed to identify trends, gaps, and emerging themes. Research Objectives: This study aims to map the research landscape on small-sided games (SSGs) in the context of team sports through a bibliometric approach and a literature review. Methods: Literature was drawn from established research sources in the Scopus and Web of Science databases from 2014 to 2023. The final data used for this study consisted of 1012 articles, which were then analysed using a bibliometric approach, and the literature review was limited to 237 articles after grouping ten types of team sports using the ScientoPy tool. Findings and Results: The results showed a consistent increase in interest in SSGs, with journals such as “Journal of Strength and Conditioning Research” and “Biology of Sport” playing an important role in expanding understanding of the topic. The analysis also revealed that authors such as Clemente F.M. and Praca G.M. had a significant impact on developing knowledge about SSGs. Although football dominated the related literature, the results also highlighted other sports such as basketball, futsal, and handball. However, there is still a lack of SSG research for sports such as cricket and dodgeball. The benefits of SSGs in team sports include improved technical skills, physical fitness, tactical understanding, and physical performance. Conclusion: This study provides insight into the important role of SSGs in athlete development and team sports training and highlights the need for further research to optimise the full potential of this training method.
