Abstract

Vocational learning processes are still dominated by one-way and theoretical teaching, thereby limiting the development of practical competencies and impacting learning outcomes. Trainer kits are used as learning media to support practice and reduce the abstraction of technical concepts. However, previous research findings on their effectiveness have been inconsistent due to contextual limitations, small samples, and variations in research design. This study aims to analyze comprehensively the effectiveness of trainer kit implementation in vocational education through a meta-analysis approach. A total of 436 articles were initially screened from Scopus and Google Scholar databases, and 22 eligible studies involving 24 independent samples were selected based on inclusion criteria. Data analysis employed the random-effects Hedges’ model with the PRISMA procedure, focusing on effect sizes derived from post-test results of experimental and control groups. The meta-analysis revealed an average effect size of 2.44, categorized as large, confirming the significant positive impact of trainer kits on cognitive, psychomotor, and affective learning domains. The findings demonstrate that trainer kits not only improve academic achievement but also enhance learning motivation and creative thinking skills. This study concludes that trainer kits are highly effective instructional media in vocational education and emphasizes the importance of their systematic integration into teaching practices. The results provide evidence-based implications for educators and policymakers to design innovative learning strategies and develop vocational curricula aligned with industry demands and 21st-century skills.

Abstract

Research on virtual laboratories has shown significant growth but is still scattered across disciplines and approaches. This condition indicates the need for systematic mapping in the context of vocational education to understand the development and direction of current research. This study aims to analyze international publications related to virtual laboratories in vocational education, covering research trends, highest citations, leading countries, and relevant publication sources. A quantitative approach with bibliometric analysis was used on 163 of the Scopus database from 2010 - 2024. Data were collected using the keywords "virtual laboratory" and "vocational education." Data analysis was carried out using Microsoft Excel and VOSviewer to visualize the research findings. The results showed that the publication trend fluctuated annually but tended to increase. Journal of Physics: Conference Series, publication of Potkonjak, and Spain were identified as the most influential countries. Co-occurrence analysis revealed major clusters such as e-learning, engineering education, virtual laboratories, and students. Overlay visualization shows a shift in focus from distance learning to a more interactive and contextual technology-based pedagogical approach in vocational education. These findings provide implications for research collaboration, pedagogical integration, and the development of immersive virtual laboratories in vocational education.
