Methodology
Meta-Analysis Findings
Proposed Framework
The study followed PRISMA 2020 guidelines, using a systematic review and meta-analysis of 27 peer-reviewed empirical studies published between 2010 and 2024. Data extraction included publication year, country, sample size, vocational field, AI technology type, and outcome measures. Inter-rater reliability for coding was strong (Cohen's kappa = 0.84).
A random-effects model revealed a moderate positive association between AI-supported assessment and skill-related learning outcomes (Hedges' g = 0.72, 95% CI [0.45, 0.98], p < 0.001). Moderate heterogeneity (I² = 39%) was observed, with subgroup analyses indicating variations across regional and institutional settings. Chinese studies showed slightly higher effect sizes (g = 0.78) compared to European/North American studies (g = 0.65), potentially due to real-world deployment focus and policy alignment. STEM and healthcare programs reported stronger gains.
A conceptual AI-supported skill assessment (AISA) framework is proposed, distinguishing empirically grounded components from forward-looking generative AI extensions. It comprises data capture (simulations, sensors, LMS), AI analytics (CV, NLP, ML for scoring, error detection), assessment/feedback generation (aligned with standards), and human oversight. Key features include real-time assessment, Explainable AI (XAI) for transparency, multilingual support, and alignment with China's National Vocational Skill Standards.

Impact of AI in Engineering Education
A notable study by Chen, Xie, & Hwang (2020) demonstrated how AI in engineering education facilitated real-time monitoring of complex performance tasks. Automated machine learning-based assessment and feedback systems supported objective grading and timely feedback in computer science and programming education. This highlights AI's role in developing technical competencies and improving vocational learning achievements in STEM fields.
