Abstract: Advanced engineering experimental teaching should be student-centered,and adopt new teaching methods and as-sessment methods according to the characteristics of experimental teaching. Taking the experimental course teaching of "Preparation and Electrochemical Characterization of Lithium Ion Battery Electrode Materials" in New Energy Materials and Devices,this paper sys-tematically introduces a new combination of small class teaching and oral examination in experimental teaching. The method and the specific implementation and effect of this method are described,and its feasibility and effectiveness are discussed. Two years of experi-mental teaching shows that this method improves the students' ability to think positively in the experimental class and cultivates stu-dents' good experimental habits. The promotion of this method will provide a useful reference for the teaching of experimental courses.
