Description¶
LEA is a course-configurable agentic AI tutoring system developed by Rumble et al. that provides chat, tutoring, and quiz interactions with adaptive scaffolding and formative assessment.
Components¶
Claims¶
- LEA's course-agnostic architecture was operationalised across three courses with no changes to the orchestrator, mastery tracker, or scaffolding engine [+M]
- RAGAS Faithfulness declines with curriculum distance from LEA's original course (0.685 to 0.499), while Answer Relevancy and Context Precision remain broadly stable across courses [~M]
- In an exploratory pilot (n=8), students rated LEA's usability, Chat Mode, Quiz Mode, learning outcomes, and trust mostly positively, with Chat Mode the strongest performer [+W]
- In simulation, LEA met or exceeded targets in Chat and Tutor modes while Quiz Mode's KC Alignment Score fell below target [+W]
