How to Cultivate Students' Preview Habits in Mathematics Teaching
"everything is established in advance, and it will be abolished if it is not planned." Preview before class is the preparation for students before class, and it is the basis for students to learn new lessons well, with the aim of improving the effect of class. Doing a good preview before class can not only cultivate students' self-study ability, but also improve students' interest in learning new lessons, grasp the initiative of learning, concentrate on solving the key and difficult points of this class, and achieve clear thinking and clear goals. It can be seen that preview is particularly important for primary school students to learn knowledge well, but preview is often ignored by us. In more than ten years of teaching practice, I focused on how to guide students to preview.

First, let students clearly develop good preview habits.

Preview is an important link in finding difficulties and a prelude to understanding and mastering new knowledge. It is easier to develop good preview habits and deepen the understanding of new knowledge. On the other hand, without preview, the lecture will have no focus and no purpose, and the class will not be able to keep up with the teacher's lecture ideas. In order to let students know the meaning of preview, I briefly introduce the importance of preview to students by combining theory with practice. On this basis, I will first introduce the importance of preview to students. In the first section, under the guidance of teachers, students will explain on the basis of preview. Through comparison, students clearly understand the significance of preview. This method is much better than the teacher's simple explanation and the students' mechanical acceptance.

1, measures to cultivate students' good preview habits

The cultivation of preview habits is the result of persistent intensive training, which can not be completed overnight. Full of tempering of will, good preview habits are also the basis for developing good learning character. On the other hand, only when the preview method is fixed by the formation of habits can it really become a method and present its due value. As the saying goes, a year's plan lies in spring, and a day's plan lies in morning. Middle school is the basic stage of compulsory education, the key moment for a person to form good study habits, and the foundation period for a person's growth. Therefore, we should attach importance to the cultivation of students' preview habits in middle school mathematics teaching, and take effective measures to train and cultivate consciously according to the characteristics of high school students' plasticity, so as to promote students to develop good preview habits.

1, teaching students scientific preview methods

At the beginning of preview, students are at a loss and don't know how to preview. At this time, teachers should teach students scientific preview methods. Generally speaking, when guiding students to preview, I adopted the following methods: (1) Study hard. First, read the contents of the textbook roughly, get a preliminary understanding of what you have learned and the idea of solving problems, and then read it carefully over and over again. Emphasis on basic concepts, concepts that are easy to confuse, but it is difficult to read concepts repeatedly. (2) think more. We should use our existing knowledge to think positively and ask why. Make it clear that this part is related to what you have learned before. (3) Mining difficulties. That is, find out the problems that you can't solve. For some problems that can't be solved by independent thinking, we should consult reference books or consult our classmates in time to try to solve them in time. (4) Solve the exercises after class, and answer the exercises after class according to your own understanding when previewing, so as to test the effect of your preview.

2. Strengthen training and training.

Due to the influence of "exam-oriented education", many teachers only attach importance to knowledge teaching and engage in sea tactics, while ignoring the cultivation of students' preview habits. Today, when we advocate the change from "exam-oriented education" to "quality education", teachers should correct their teaching ideas, start with improving students' quality, pay attention to training and exercise in teaching, and let students develop good preview habits. In the process of teaching, I adopted the following methods: (66) (2) Check on time to promote the formation of their habits. At the beginning, before each new lesson, the teacher reported the preview in groups, and each student had to express his own views. The main content of the report is: the main content of this class, which places are difficult to grasp, which places are not understood, and which are the key points of this class. After the group report, each group reports the discussion results. Teachers adjust plans in time according to students' feedback, and give some suggestions for the key points that students generally think are difficult to grasp. Before each new lesson, we should report the preview situation in groups, and each student should exchange opinions so that students can preview consciously. Over time, I also developed a good preview habit. (3) When students make little progress in preview, they should be encouraged in time to go up a storey still higher. For students who are slow to develop preview habits, don't be cynical, be patient, give specific guidance and look forward to progress.

In short, in optimizing classroom teaching, teachers should seize every link in time, stimulate students' learning emotions as much as possible, create various conditions, and let students learn to actively explore new knowledge.
