Abstract: In order to improve the teaching effect of materials mechanics and to cultivate students' ability to analyze and solve practical problems, the reform and the practice of the teaching method based on outcome based education (OBE) are carried out. Taking the college students majoring in mining as the teaching object, and with consideration of the latest developments in the roadway support technology, the roof bolts, the piers, the drilling bolt holes, the optimization of the roof anchor arrangement of roadway, the failure analysis of the steel tube concrete support and the stability analysis of the pier column are adopted as the examples of the axial tension, the axial compression, the torsion, the bending, the combined deformation, and the compression rod stability, respectively. Then, the cases are analyzed by using the knowledge of materials mechanics in related chapters. The OBE teaching method enables students to deeply understand the close relationship between materials mechanics and their majors. It can stimulate students' interest in learning and cultivate their scientific literacy and research thinking. In addition, it enables students to practice the skills of innovation and solving engineering problems. The teaching effect based on OBE is remarkable.
