Abstract: Aiming at the problems of poor traditional classroom teaching effects of electrical engineering courses, the lack of close connection between experimental teaching and engineering practice, and the single way of teaching assessment, based on the condensing of electrical engineering teaching experience, the examples of in-depth teaching interaction are introduced from three dimensions: theoretical teaching, experimental teaching, and teaching assessment to explore the teaching interaction mode and improve the teaching effect of electrical engineering, which has achieved good teaching effects in the teaching practice of electrical engineering.
