Abstract: Simulation technique has been widely used in the teaching center of experimental physics，China University of Geosciences，Beijing for almost 20 years. In order to figure out how the students think about this technique and how much it has positive effect on their learning，we have handed out the questionnaires to the students who have gone through the whole line of the simulation system. The result shows that the students are not really used to the system although they are aware and agree that the simulation system is good for them. In the last part of the paper，the useful suggestions are proposed.
