Looking at problems outside of the environment is a hooliganism. To be able to pass the exam to Tsinghua and Peking University, the teacher first asked him to teach students who had impacted Tsinghua and Peking University. He had that need. It is estimated that only one of the 100 high schools in China will be able to take the Qingbei candidates (I may not be sure, probably the meaning is in place). Most of the remaining teachers can’t even understand the class. I know that there are already more than one student following. I have to use Xiao Yuan to search for questions by my own teacher, including many of my colleagues. They are not very capable and can only bring poor students to live with them. There is even a junior high school math teacher among my colleagues who is often recommended by the company. Those who came up to teach two high school art examination classes, one can imagine how different the level of high school math teachers is. This kind of teacher asks him to take the college entrance examination to Qingbei… emm is indeed impossible. However, for teachers of key classes in first-line schools, doing questions is really a basic skill. Why can I tell the students if I don’t understand? In fact, this is not only a difference in experience, but also includes adults’ crush on the ideological level of minors. After graduating from university, I spent half a year, even teaching and practicing, and the level of my self in high school dropped a lot. I am a contestant in high school. I am in the top five in mathematics competitions in the province. I am crazy about math questions in the college entrance examination every day. It takes one and a half hours to one hour and 45 minutes to make a set of math papers, and many methods seem to be troublesome now. . Doing a set of math papers now takes 40 minutes, basically the most standard way to locate it at a glance. I asked my students that the teachers in the best public schools are now very good at doing questions, and being able to do questions is only the teacher’s first requirement. The requirement of an excellent teacher is probably that first of all, they must be able to do the questions, secondly they must use the most standard, the most suitable way for students to do the questions, secondly, they must explain the topics clearly, and secondly, they must summarize and categorize the topics, and the same test sites. The questions are collected together, and then a specific knowledge system is formed. For example, when I talk about trigonometric functions today, those knowledge points will be tested on trigonometric functions. I must quickly filter and select a set of the most representative questions for students. Cover all test sites, and then design different question sets according to the requirements of students in different grades, and understand the difference between students’ thinking and their own thinking in the process of contact with students. Like me, students from Qingbei, from the 30s to 40s, have to teach the basics. Those who need to teach are convinced and trust me completely. There are no two brushes. In this process, the level of different teachers has been opened up: some teachers are very good at doing questions, but the methods used are too difficult for students to think of, and the effect of speaking is not good; some teachers have no system, and they think about it. Some test sites often fail to teach. If students do not cover the contents of the exam, they will naturally be dissatisfied with the teacher; some teachers have a very clear system, from point to surface, they can pass one or two questions to get the whole piece of knowledge Point to make it clear. Teachers of commercial organizations also require marketing skills, typesetting when designing handouts and PPT, design elements, not as rough as school teachers, and good home-school communication, urging parents to pay, and managing things other than learning… Questioning is really the most basic of these things.
