Abstract: Physical chemistry is a basic course for undergraduates majoring in metallurgical engineering as well as resource processing and recycling. Under the background of the construction of "first-class major", the construction of "first-class curriculum" is carried out. Taking the problems existing in students' learning of physical chemistry course and the teaching difficulties caused by the intrinsic characteristics of physical chemistry course as "problem-oriented", the teaching reform is carried out from the aspects of teaching content, teaching methods as well as ideological and political integration. After the reform, students' learning effect has been improved significantly, and students' patriotic feelings and professional identity have been improved.
