Professional courses play a very important role in students’ cultivation of engineering specialties. Most colleges pay a great attention to the fundamental courses, so the quality of the courses is usually guaranteed. However, professional courses sometimes do not receive as much attention as fundamental courses do, and the quality is often out of control. We pointed out that the purpose of professional courses was to guide students to use their knowledge to analyze and figure out problems in the professional field rather than imparting knowledge. The relationship between lecturing and textbooks was analyzed in this paper. And the design of class discussion, exercises, and examination were discussed as well.
