The reporter group of Wuhan Institute of Engineering and Technology recently interviewed 100 students from different universities and majors for a questionnaire survey. The results show that 75% of the students think that teachers should focus. They believe that grasping the key points can make the review more efficient and targeted, and it is to sort out the knowledge points in order to better prepare for the exam. The students who disagreed said, "As long as you listen carefully at ordinary times, you will naturally be able to tell which are the key points."

Xu, an excellent head teacher in Hubei University Business School and an associate professor in the Department of Economics, said that he has been insisting on "not focusing on the key points" for 10 years. In Weibo, he was exposed to the failure rate of 40% at the end of two economics courses, and was "bombarded" by students: Teacher, you are so poisonous. Xu said yesterday that marking the key points before the exam can only be exchanged for seemingly beautiful transcripts, which can't confirm the real level of students. So he doesn't usually focus on students. "On the one hand, this is not allowed by the school, and it is unfair to those students who are serious in class; On the other hand, I also hope that students can pay attention to learning and accumulation in peacetime, rather than cramming at the end of the term. "

Of course, some teachers said that if you don't draw the key points, the final evaluation given by students will be ugly; If there is a large-scale failure, the pressure on teachers is also great.

How can we reduce students' dependence on "concentration"? Some teachers have come up with innovative evaluation methods. Teacher Shen Liangping from the School of Physics and Electronic Science of Hubei University canceled the final exam, moved the class to the laboratory, divided the theoretical knowledge into several topics, and assessed the students through usual exams, tests, questions and homework. In order not to let the students have the luck of "speculation before the exam".
