Abstract: Taking the teaching practice of “material thermal expansion coefficient measurement experiment” as an example, focusing on the multi-level experimental teaching objectives of cultivating undergraduates’ rigorous scientific attitude, autonomous learning ability and practical innovation ability of material-major undergraduates, this paper describes how to design and expand experimental teaching content, guide students to control the details of the experimental operation, preset questions to guide students to think actively, refine experimental knowledge points, and so on, and achieve the capability cultivation of talents throughout the whole process of experimental teaching. Furthermore, it is proposed that experimental teachers in colleges and universities should strengthen autonomic learning actively and deepen the construction of experimental courses and improve the quality of talent cultivation under the background of deepening the educational reform.
