Under the traditional teaching mode of architectural education, it is difficult to truly experience the real state of ancient space. In addition to blackboard writing, traditional teaching mainly depends on the application of digital media. However, regardless of photos or videos, the cognitive subject is always outside the media, and the information received by students is relatively indirect. The application of virtual simulation technology takes existing objects as the skeleton to virtualize the original appearance, changes and deficiencies of ancient architectural pattern, so as to communicate the ancient and modern, experience scenes in an immersive way. The combination of virtual experiment and traditional curriculum can achieve the "combination of virtual and real" in teaching, and attain the real "communication between ancient and modern".STaking the exploratory practice of Chinese ancient local urban space cognition and analysis virtual simulation experiment in the teaching of Brief History of Chinese Architecture as an example, this paper expounds the important value of computer virtual simulation technology in the curriculum of architectural history, evaluates its advantages over traditional education methods, and reflects on some problems when using the virtual simulation technology in the current curriculum.
