The blended teaching method deeply integrates the advantages of MOOC and traditional classroom education, which is a new mode of training innovative engineering talents in universities. However, the author encountered problems such as insufficient input from students and a sharp drop in the number of courses in the mixed teaching practice. Based on the methods of blended teaching practice and student questionnaire surveys, the problems and causes of the blended teaching of professional courses are deeply analyzed from the perspective of students and specific improvement measures are proposed in this paper. Students are willing to change the traditional classroom teaching methods, but self-study, seminars and too many courses which taking lots of time in the blended teaching affects the student’s willingness to choose blended teaching. Moreover, the investment of a large amount of study time does not reflect the obvious improvement of course grades which can also have an impact on student’s choices. Based on the students" standpoint, some improvement measures, such as optimizing the curriculum teaching arrangement, stimulating students" internal drive, innovating the curriculum teaching mode, paying attention to backward students and improving teachers" self-accomplishment, etc. are put forward and put into practice in teaching. And good teaching effect have been obtained.
