Learning State Vector Model: Multi-Dimensional Student Modeling for Governed Educational AI

Managing student state as high-dimensional vectors with responsibility-gated interventions that prevent harmful over-optimization of learning pathways

Many educational AI systems still optimize around narrow metrics such as test scores, completion rates, or engagement time. Learning, however, is multi-dimensional: knowledge, confidence, motivation, metacognition, and social skills evolve on different trajectories. This paper introduces the Learning State Vector Model, representing each student as a high-dimensional state vector so tutoring agents can make governed decisions across dimensions and reduce harmful single-metric over-optimization.

Over-Fixation Suppression: Control-Theoretic Stabilization of AI Recommendation Convergence in Education

Preventing AI tutoring systems from converging on single recommendation patterns through diversity-enforcing stability constraints

Left unconstrained, recommendation algorithms can converge to narrow patterns: similar problem types, difficulty bands, or teaching approaches. In education, this can create learning monocultures that limit broader development. This paper develops a control-theoretic framework for suppressing over-fixation in educational AI while preserving learning effectiveness.
