Under the traditional teaching mode of architectural education, it is difficult to truly experience the real state of ancient space. Traditional teaching mainly depends on blackboard writing and digital media. The cognitive subject is always outside the media, and the information received by students is relatively indirect. Virtual simulation technology takes existing objects as the skeleton to virtualize the original appearance, changes and deficiencies of ancient architectural pattern. 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. Taking the exploratory practice of virtual simulation experiment in the teaching of brief history of Chinese architecture as an example, this paper expounds the important value of virtual simulation technology in the curriculum of architectural history, evaluates its advantages over traditional education methods, and reflects on some problems when using virtual simulation technology in the current curriculum.
