Clinical molecular biology laboratory technology course is the core course of medical laboratory technology specialty.It has the characteristics of boring,abstract and strong practicality.Traditional classroom teachers unilaterally instill teaching,which often leads to students'burnout and fear of difficulty.In this study,the teaching mode of the divided classroom is progressive in the way of classroom teaching-internalization absorption-classroom discussion,so that students can gain the initiative of classroom learning and further improve the two-way efficiency of classroom teaching and learning.At the same time,combined with the mobile learning platform,it provides students with self-learning micro-learning resources,which is conducive to extending limited classroom learning to after-school;practice has proved that the mobile micro-learning+PAD classroom teaching mode has effectively improved students'academic performance and learning enthusiasm and participation,and has achieved new breakthroughs and innovations in curriculum teaching.
