From 'Answering Questions' to 'Mental Simulation': Paradigm Shift in Educational AGI and Unresolved Issues

The "mental simulation" direction proposed in the Tianli Qiming white paper theoretically touches on the core contradiction of educational intelligence—the "impossible triangle" of quality, cost, and scale. But we need to ask: do current technical solutions truly transcend the "surface-level content distribution" to achieve modeling of the learner's internal cognitive logic? From the perspective of NLP and knowledge graph researchers, there are still several debatable aspects regarding the experimental design and evaluation standards for this declarative shift.
