Abstract: A practical teaching system combining virtual reality with multi-layer progression was designed aiming at the shortages of traditional electromechanical control experiment teaching such as single teaching method, low teaching efficiency and high operating expenses. The system combines the virtual simulation experiment with the physical experiment based on the self-made TT-JD-1A electromechanical control cabinet. The experimental content is divided into cognitive experiments, basic experiments, comprehensive experiments, and innovative experiments, which run through the four-year study of undergraduates. The results show that this kind of experimental teaching system, which combines virtual reality, multi-layer progression and complementary advantages, can guide students to learn autonomously, inquiryly and innovatively, and cultivate students’ teamwork spirit and engineering practice ability, improve learning efficiency and the quality of experimental teaching.
