We have taught programming in first-rate university, normal collage and junior college, and taught students at all levels. Through the use of various teaching methods and comparative analysis of teaching effects, we found that the task-driven teaching method can significantly improve the teaching effect when it is applied to the programming course, so it is worth trying and promoting its application. However, for different levels of students, different implementation plans are needed, and the corresponding practical environment and assessment mechanism are required to achieve the desired results.
