Abstract: Traditional teaching mode cannot manoeuvre students initiative, and students cannot master many abstract professional knowledge. So this paper attempts to introduce a new teaching mode that the teacher introduces validation experiments related in the theoretical teaching process, expecting to achieve a better teaching effect. The teacher introduces the corresponding experiment during the course of the introduction of the theory, and students will be easier to master the theoretical knowledge through doing the experiments by themselves than before. We adopt the proposed teaching mode in a part of 2013 degree undergraduate students of electronics and information engineering, the experiments exam scores and the final exam scores are 8% and 5% higher than the traditional mode, respectively.
