The blended teaching method deeply integrates the advantages of MOOCs and traditional classroom education, which is a new mode of engineering talents training in universities. However, in teaching practice, problems such as insufficient student engagement and a sharp decline in course enrollment have emerged. Based on the practice of blended teaching and student questionnaire surveys, the problems and causes of the blended teaching of professional courses are deeply analyzed from the perspective of students. Students are willing to change traditional classroom teaching methods, but the conflict between the excessive time required for self-study and discussion after blended teaching courses and the large number of courses they take affects their willingness to choose blended teaching. Based on the students’ standpoint, some improvement measures are put forward, including optimizing the curriculum teaching arrangement, stimulating students’ internal drive, innovating the curriculum teaching mode, paying attention to backward students and improving teachers’ self-accomplishment.
