With the rapid development of the software and design industry, the teaching content, teaching time, teaching methods, and teaching links have been challenging to meet social needs. Based on the teaching practice and the investigation of graduates, combined with the characteristics and existing problems of the course, this paper puts forward the exploration of teaching reform from the four aspects of teaching content, duration, mode, and connection. The article puts ahead of the teaching content of “3+1+X” and the “three steps” teaching plan. It also includes one case teaching, classroom recording, and class network interaction to provide some suggestions for the teaching reform of this course.
