A systematic review of generative AI in higher education learning analytics and decision support
摘要
The rapid advancement of generative artificial intelligence (GenAI), particularly large language models (LLMs), has introduced transformative possibilities for learning analytics (LA) in higher education. Despite growing empirical work, no prior review appears to provide an integrated synthesis of GenAI studies in higher education learning analytics through the combined lens of functional roles and decision support applications. Existing reviews address broader AI-in-education topics or isolated learning analytics functions rather than providing an integrated synthesis of these dimensions. This paper presents a systematic review of 38 studies, following the PRISMA 2020 guidelines, to address four research questions: (RQ1) what GenAI techniques and models are used in higher education LA research; (RQ2) what functional roles GenAI performs across LA processes; (RQ3) what decision support applications are enabled; and (RQ4) what research gaps and future directions exist. Drawing on studies retrieved from Scopus, Web of Science, and IEEE databases, supplemented by citation snowballing, we propose a taxonomy of six functional roles and identify nine categories of decision support applications. GPT-4 and related models emerged as the dominant technologies, while multimodal LLMs, retrieval-augmented generation, and generative adversarial networks represent emerging AI directions. The review reveals critical gaps in scalability, equity, interpretability, longitudinal evaluation, and ethical governance. These findings provide a foundation for researchers, educators, and institutional decision-makers seeking to leverage GenAI in educational practice.
