Quantum mechanics teaching plays a fundamental and leading role in the teaching system of higher engineering colleges, and it is also an important task in the construction of New Engineering. To promote the teaching reform and innovation of quantum mechanics, we must focus on improving the quality of engineering education, adhere to advanced teaching concepts, aim at the forefront of world science and technology development, improve and enrich teaching contents, adopt a variety of new teaching models, and use multimedia and network technology to improve teaching effect and quality. At the same time, it is necessary to strengthen humanistic education and the guidance of scientific research on teaching, and improve college students' humanity accomplishment and competence in innovation and scientific research, so as to promote the construction of New Engineering and cultivate high-level innovative talents to meet the requirements of the new era.
