This paper analyzes the difficulties faced by the teaching of courses. Under the circumstances of single traditional teaching mode, simple experiment content and single course assessment, the application of artificial intelligence technology in the organization and implementation of immersion teaching is proposed. Through the application of this information technology, the course of Communication Electronic Circuit has achieved good teaching results. The students’ satisfaction has been improved, and students’ participation has been improved, and the proportion of students awarded has been greatly improved.展开更多
