Assessing the Impact of Virtual Reality on Technical Skills Acquisition in Vocational Education

Thesis Abstract

The rapid advancement of digital technologies has increasingly influenced vocational education, prompting the need to evaluate innovative teaching tools such as virtual reality (VR) for skills development. Despite growing adoption, empirical evidence on the effectiveness of VR in enhancing technical skills acquisition remains limited, particularly in real-world instructional settings. This study aims to assess the impact of virtual reality on the acquisition of technical skills among vocational students, with specific objectives to determine the comparative effectiveness of VR-based training versus traditional methods, to explore students’ perceptions of VR learning, and to identify key factors influencing skill retention and transfer. Employing a quasi-experimental research design, this investigation involved a sample of 200 final-year students enrolled in mechanical and electrical vocational courses at technical colleges, chosen via stratified random sampling to ensure diversity across disciplines. Data collection instruments included standardized technical skill assessment tests, questionnaires measuring learners’ motivation, engagement, and perceptions towards VR, and structured interview protocols for qualitative insights. The reliability of the instruments was validated through Cronbach's alpha coefficients exceeding 0.80, and content validity was established via expert review. Quantitative data were analyzed using descriptive statistics, independent t-tests, and multiple regression analysis, while thematic analysis was employed to interpret qualitative interview data, providing a comprehensive understanding of learner experiences. The study hypothesizes that VR-based training significantly improves technical skills compared to conventional instructional methods, with enhanced motivation and engagement mediating this relationship. Based on the Technology Acceptance Model (TAM) and Experiential Learning Theory, the conceptual framework guides the examination of learners’ acceptance and active participation in VR environments. It is anticipated that findings will demonstrate that VR offers a more immersive, interactive, and effective learning experience leading to higher skill acquisition scores, improved retention, and greater transferability of skills to practical tasks. The research is expected to fill existing empirical gaps by providing rigorous quantitative and qualitative evidence on VR’s efficacy in vocational settings, thus informing curriculum development and instructional design. The study ultimately concludes that integrating VR into vocational training significantly enhances technical competence and learner motivation, though challenges such as initial costs and technological literacy must be managed. Recommendations include adopting a blended learning approach combining VR with traditional methods, investing in infrastructural support, and providing ongoing teacher training to facilitate effective implementation. The findings contribute to the emerging body of knowledge by establishing a causal link between VR-assisted instruction and skill acquisition, supporting policy formulations aimed at modernizing vocational education through immersive technologies. Future research avenues are suggested to explore longitudinal effects of VR training and its cost-effectiveness across diverse vocational disciplines. Overall, this study underscores the potential of VR as a transformative educational tool that can revolutionize skills training, foster learner engagement, and produce workforce-ready graduates in the evolving technological landscape.
