Abstract: Since the interactive teaching and learning has become an indispensable part of undergraduate experimental teaching, a virtual simulation teaching experiment center should also introduce advanced teaching concepts and incorporate interactions into the entire experimental teaching process. At the same time, massive excellent teaching resources should be utilized rationally to give full play to virtual simulation teaching and e-leaning. As a result, a unique innovative teaching pattern is thus created with its own distinctive characteristics, such as interactive teaching and group discussion in a network environment (including LAN environment and non-LAN environment). In practice, the traditional teacher-oriented learning is completely abandoned, and the students, previously seen as the teaching objects, are fully involved in teaching activities. They are given opportunities to express their views and encouraged to actively participate in teaching activities. A full interaction bond is created between teachers and students. The pleasant atmosphere allows the teacher to truly fulfill the teaching role of answering questions. In short, interactions are of great practical significance for guiding students to active learning, improving teaching efficiency and promoting the cultivation of innovative talents.
