Three important reforms in education have been in progress step by step, including classroom teaching, innovative training and virtual laboratories. At first, for enhancing and integrating the existing courses related to the circuit, so that the students can comprehend the existing knowledge much more effectively, an important and effective curriculum reform has been performed by combining ``Circuit Analysis'' and ``Analog Circuit Foundation'' into one course; Then, innovative training has been carried out to cultivate the team skills among the students; Finally, in consideration of the rapid development of the electrical and electronic experiment, the conventional laboratory equipment may not satisfy the demand of every student due to financial constraints, therefore, the construction of virtual simulation experiment center is an efficient way to break this bottleneck.
