With the promulgation and implementation of the new curriculum, teachers are paying more and more attention to the efficient and practical discussion teaching method (DTM) in the current teaching of undergraduate course. DTM is affected by discussion methods, software and hardware facilities, and corresponding rules and regulations. So many problems should be concerned and solved in the application of DTM. Combined with the bridge engineering course teaching, we studied on effective DTM in the view of professional engineering to find a practical and efficient DTM, which is suitable for engineering majors and effectively improve the efficiency of the classroom teaching.
