Solid state physics is to understand how solid materials behave，the understanding of solid materials has gone through from the shape of the surface to the inner structure，from the large - scale properties of solid materials to their atomic -scale properties，from the qualitative analysis to the quantitative calculation，from the superficial phenomenon to the physical nature. We have taught solid - state physics over the course of this and summed up the following teaching experiences: using the phenomenological view to look at the solid state physics problems; figure out the internal logic relationship of the book between chapters and section; based on author’s research field，establishing the internal relation of frontier science and basic knowledge in solid state physics; traditionally and multimedia educational model to cooperate with each other; cultivating students’thinking ability by using after class homework. We hope this paper could provide new ideas and methods to make students gain a deep understanding of solid state physics.
