Abstract: The classroom teaching of gear generating principle experiment by traditional mode results in insufficient classroom time and poor teaching effect. A kind of blended teaching mode on this experiment is designed and studied. The perceptual knowledge of this experiment is established by micro-lecture video and teacher-student interaction when students prepare for class. The understanding of basic concepts for students is deepened by question guidance and knowledge summary in classroom teaching. Experimental results show that this blended teaching mode can not only greatly enhance the classroom efficiency to make students finish experiment task with high quality on time, but also promote students’ mastery of target knowledge points, which leads to the significant improvement of teaching effect.
