Abstract: Based on Gauss theorem in electromagnetic field and electromagnetic wave，in this paper

the design of teaching with teachers as the main body is carried out，in which there are five

teaching links: introduction，es- tablishment，breaking，extension and conclusion，so as to realize

the teaching conception of knowledge inheritance and ability migration. Integrating the ideological

and political elements into the curriculum from three dimensions not only solve the teaching

difficulties，such as determining the size of the spatial angle，the key meaning of

positive and negative，and the calculation of the spatial angle of closed surface，but also guide

students to see problems from multiple perspectives，and help students to establish a correct

outlook on life，values，and the world，so as to real- ize the goal of condensing the knowledge in the

value dissemination and realizing value guidance in the knowledge dissemination.

Key words: course ideology and politics, Gauss theorem, the spatial angle, Coulomb's law
