This use case points to NotebookLM as a teacher-curated companion to navigate content in complex units. It could support active learning, self-regulated learning, and constructivist engagement while keeping the knowledge source base bounded. For educators, it suggests a model for sharing AI-assisted study spaces that are shaped by course design rather than left entirely to student improvisation. Importantly, it reinforces the need for pedagogical control, ensuring AI use aligns with learning outcomes. In this way, AI enhances clarity, confidence, and engagement, while maintaining academic rigour and supporting deeper understanding.
