In view of the shortcomings of the current traditional teaching mode in the cultivation of innovative professional talents, the two courses of thermal equipment principle and heat exchanger principle and design of energy and power engineering are taken as examples to discuss the differences between diversified practice teaching methods and traditional teaching mode under the background of excellent engineers training. Diversified practice should be strengthened during the course teaching process, including multimedia courseware design, engineering case analysis, off-campus engineers entering the classroom and experiment, actual engineering design and practice on project site. The teaching content allows students to carry out indepth and comprehensive learning from basic knowledge, case application, experimental phenomena and results analysis, engineering field practice, etc. Diversified practice can improve students’ interest in learning and comprehensive practical ability, and also cultivate outstanding engineers who can meet the needs of society.
