Abstract: With the shortening of class time and the expansion of enrollment scale,in order to meet the requirements of higher education personnel training quality and improve students' comprehensive quality and practical ability,this paper analyzes the charac-teristics of the basic deformation content of material mechanics course and main problems encountered in the current teaching process, and puts forward the "autonomous" teaching mode that combines theoretical teaching and experimental teaching. This model emphasiz-es the importance of experimental teaching. It is mainly based on student research-based learning,supplemented by teacher guidance and answering questions. It has a multi-level comprehensive assessment method,which is conducive to deepen students' understand-ing of teaching content and achieve comprehensive improvement of material mechanics. The purpose of the teaching effect.
