Abstract: ：Aiming at the high degree of integration of teaching instruments, the lack of independent operation and innovative thinking, and the lack of support for the improvement of students' practical ability in the basic experimental teaching of energy and power majors, the experimental teaching mode is explored based on constructivist theory. Taking "Engineering Thermodynamics Experiment" as an example, task-guided teaching is carried out based on the existing equipment conditions. Through the problem to inspire students' positive thinking activities, with tasks as the main line to organize and regulate experimental teaching, teachers change from knowledge transmitters to teaching organizers and guides, creating a new scene of students' independent exploration and cooperative learning.

Key words: New engineering education, Constructivism, Experimental teaching, Teaching model, Energy and power class, Teaching reform
