Building Immutable Skill Trees and Prerequisite Graphs
Linear textbook chapters force rigid progression models that ignore individual learner competencies and knowledge gaps. Graph-based skill trees connect atomic concepts via directed acyclic edges, allowing dynamic curriculum routing.
Skill Graph Invariants
- Directed Acyclic Edges: Notes declare explicit prerequisite requirements via incoming wikilinks (
prerequisites: Concept A). - Unlock Condition Evaluation: Advanced topics remain locked until underlying card stability metrics exceed threshold tolerances.
- Personalized Remediation Paths: Lapsed reviews automatically trigger review queues for foundational prerequisite nodes.
Graph-driven education adapts to the learner’s actual cognitive state rather than arbitrary chapter boundaries.
