CDIO emphasizes that students are involved in the engineering study in an active, practical and comprehensive way. In this paper, charge interaction teaching is to be discussed as a case for the CDIO educational concept on how to train students to master the basics of engineering, improve personal ability and teamwork spirit, and enhance engineering system capabilities and so on. The teaching content designed around Coulomb's law is divided into four parts: ① Ideas. Students are required to access in advance to other scientists viewpoint about the force of the charge, which enable students to understand the importance of thinking of previous work on refining. In other words, "Conceive" is not groundless. ② Experimental design. Students are required to find that how Coulomb utilized his professional expertise to design Coulomb Twist balance, and how to use the secondary amplification principle to make micro amount being magnified. It should be emphasized that engineering design is related to the overall quality of the individual. ③ Analogy Method. Analogy Method is an important method of scientific research. The students should understand the analogy relationship of Coulomb's law and Newton's law of gravitation, consider the method connotation behind the Coulomb experiment. ④ Class discussions. Group discussions is used in classroom teaching aiming at improving students teamwork, each member of the group should finish his corresponding work assigned in advance before the class, discuss in class, and eventually present a PPT report. Compared with traditional electromagnetic theory teaching, this paper emphasizes the idea premise of establishing scientific experiments, the design and implementation of experimental as well as other aspects. This method avoids the traditional teaching of coulomb’s law on the theory learning only and gives more attentions on developing innovative ideas. As for operation in classroom teaching, discussion stimulates students’ initiative of active learning and cultivates their teamwork spirit. It fully reflects the significance of applying CDIO concepts into the teaching reform in the field of electromagnetic theory.
