Abstract: Circuit experiment is a specialized core course for students majoring in electrical information, and it is also very crucial to cultivate the practical ability and innovative consciousness of students. In view of the problems existing in the teaching of circuit experiment, based on Rain Classroom teaching platform and Multisim simulation software, we explore and practice a blended experimental teaching system combining virtualization and reality in this paper. The specific design of this teaching system is elaborated from three aspects, including teaching content, teaching mode and evaluation system. Teaching practice shows that the proposed blended experimental teaching method with the combination of virtualization and reality stimulates students’ enthusiasm and initiative, enhances students’ operational ability and innovative ability, and better teaching results are achieved.
