Architectural design basic course is constrained by site constraints and traditional teaching mode, there are shortcomings of lack of engineering practice ability training, repetitive teaching, and students’ difficulty in understanding three-dimensional space. So, the virtual simulation experiment of Chinese southern pavilion construction of Zhejiang A&F University is developed. "Virtual construction" module is developed for engineering practice ability training, "basic cognition" module is developed for repetitive teaching problem and "case learning" module is developed for three-dimensional spatial cognition understanding problem, and explores the reform of teaching methods suitable for it. Teaching practices shows that virtual simulation experiments can largely compensate for the shortcomings of traditional teaching mode. With the continuous development and maturity of high-tech information technology, virtual simulation experiments will play an increasingly important role in teaching activities effect.
