The application of artificial intelligence technology in geography education is generally constrained by AI illusion, which leads to distorted knowledge output and poor teaching eff ect of AI. This study follows the logic of“problem identifi cation - technological breakthrough - practical verifi cation - eff ect evaluation”, and builds an AI learning platform themed on the Grand Canal based on retrieval enhancement generation technology, eff ectively alleviating the problem of AI illusion and forming a collaborative teaching method of“teacher-led and AI-assisted”. Based on three practical data from the fi rst-year geography class of Nanjing Foreign Language School, this article fi nds that students are highly satisfi ed with the creative creation module in the platform, and the previewing support eff ect is signifi cant. To a certain extent, this affi rms the educational eff ectiveness of the AI learning platform.
