Description

LEA is an adaptive AI study-aid platform that infers higher-education learners' cognitive, motivational, and engagement states from behavioural and performance indicators to guide scaffolding.

Components

• Integrated Psychological Framework: cognitive load, ZPD, engagement, and motivation theories grounding LEA's learner-state modelling: LEA's adaptive mechanisms are grounded in four frameworks — Cognitive Load Theory, Zone of Proximal Development and constructivist learning theory, engagement theory (Self-Determination Theory and Situated Expectancy-Value Theory), and motivation and self-efficacy theory (Bandura's Social Cognitive Theory and Zimmerman's self-regulation model). Together these "define the Integrated Psychological Framework that informs LEA's learner-state modelling and scaffolding decisions via the Agent Orchestrator." Cognitive load is computed as a weighted combination of task difficulty, recent accuracy, fatigue, and task type; ZPD is the mean accuracy across the last four responses targeting a 50–80% performance band; motivation state is inferred from persistence, sentiment, and performance trends. (Rumble et al. (2026))

Claims

• Tutor Mode's adaptive responsiveness was overestimated by simulation: only 3/8 pilot participants agreed LEA adapted appropriately when they expressed uncertainty [~M]
• Behavioural engagement indicators such as platform interaction and task completion do not by themselves establish cognitive engagement with mathematical ideas [~W]
