Abstract: In order to overcome the students 'fear in learning material mechanics psychologically, reduce the difficulty of students understanding of key concepts, and improve their enthusiasm for learning, and also to make the research teachers of research and teaching, this paper puts forward a kind of scientific research-teaching. It is applied in teaching of material mechanics driven by the interactive mode. This method introduces the research methods and research process in the scientific research into the course teaching. It makes the difficult comprehension concept concrete and clear, and reduces the learning difficulty and eliminates the students' fear in psychology. While strengthening theoretical study, it also cultivates students innovative thinking ability and engineering practice ability, which is favored by students.
