With the rapid advancement of artificial intelligence technology in education, AI-driven gamified learning environments offer innovative pathways for primary English vocabulary instruction. Grounded in self-regulated learning theory, this study systematically examines the mechanisms through which AI-personalised gamified environments influence metacognitive strategy development in primary pupils’ English vocabulary acquisition. Through a meta-analysis of 45 empirical studies conducted between 2019 and 2024, the research reveals that AI-driven gamified learning environments demonstrate significant effects in promoting vocabulary acquisition (Cohen’s d = 0.72), enhancing metacognitive awareness (Cohen’s d = 0.68), and improving learning persistence (Cohen’s d = 0.64). Adaptive feedback mechanisms played a crucial mediating role, effectively fostering learners’ self-regulation capabilities by dynamically adjusting learning pathways and delivering personalised guidance. The study further revealed the significant moderating effects of cultural context, technology acceptance, and teacher support on AI gamification outcomes. This research provides theoretical foundations and practical guidance for AI applications in language education, holding considerable value for advancing the design of personalised language learning environments.
