It is the mainstream to promote the deep integration of artificial intelligence (AI) technology in the teaching of architectural disciplines. Based on the artificial intelligence teaching support system, we have developed and built an AI teaching core platform and an expansion platform for the special seminar on “Urban Green Space System Planning”. Multiple support scenarios have been established to meet the teaching needs of both teachers and students in three stages: pre-class preparation, classroom implementation, and post-class feedback. With open-topic preparation, discussion, and knowledge point analysis as clues, we have constructed an intelligent teaching system that integrates reality and virtuality, featuring two wings of “teacher - platform - student” integration. The feedback results show that the introduction of the AI ??teaching platform has improved teachers’ lesson preparation efficiency and enriched teaching scenarios. At the same time, students have enhanced their mastery of course knowledge points by utilizing the platform’s question-answering and resource recommendation functions. This achievement provides a theoretical framework and technical path for transforming smart education in architectural majors, and the teaching model it constructs offers new ideas for addressing common teaching problems in design majors.
