Multi-media teaching have been widely used to high education at present, which brings vigor to class teaching. The advantage and common problems of multi-media teaching for specialized courses in engineering are analyzed in decade. How to optimizing multi-media teaching means is discussed and some suggestions about improvement effect of multi-media teaching are put forward in this paper. As an example of fundamentals of control engineering course, teaching feature and multi-media teaching means to reduce difficulty of both teaching and learning are studied. The virtual simulation teaching is implemented based on the link technique of PPT and Matlab, which can overcome the disadvantages that do not carry out dynamic calculation and plotting in PowerPoint. This provides a new approach for optimizing multi-media teaching means.
