With the rapid development of Internet technology，the traditional university physics experiment teaching has been difficult to apply to the complex teaching scene in the new era．In view of the shortcomings of traditional college physics experiment teaching，this paper analyzes and compares the advantages and disadvantages of online and offline teaching modes．Through the combined use of online teaching resources，home physics experiment and virtual simulation platform，an online intelligent classroom of college physics experiment is constructed，and a new teaching reform strategy of college physics experiment is explored in order to improve the traditional experimental teaching mode． To promote the reform of experimental teaching in colleges and universities，improve students’physical thinking ability and independent experimental ability．
