Enhancing Explainability of Knowledge Learning Paths: Causal Knowledge Networks

Transparency in educational AI requires structured knowledge models: The paper demonstrates that building educational systems on explicit causal knowledge networks—rather than "black box" algorithms—allows educators and students to understand why specific learning paths are recommended, addressing a key concern in responsible AI implementation.

Causal relationships matter more than correlations alone: By moving beyond simple statistical associations to identify actual causal connections between concepts, the system can provide more reliable and trustworthy recommendations, reducing the risk of misleading students down ineffective learning paths.

Explainability supports accountability in adaptive learning: The emphasis on maintaining "transparency in the decision-making process" means that when an intelligent tutoring system recommends a particular lesson sequence, educators can verify the reasoning and hold the system accountable—essential for responsible deployment in educational settings where decisions affect student outcomes.

Trustworthiness is foundational, not optional: The paper frames a "reliable knowledge structure" as a prerequisite rather than an afterthought, suggesting that responsible AI in education should prioritize building trustworthy systems from the ground up rather than attempting to explain opaque systems after deployment.
