In the past, under the control of exam-oriented education thought, review was to systematically sort out the mathematical knowledge and basic skills learned, so that students could better master the knowledge and get good grades in the exam. Therefore, we often unconsciously aim at the examination questions and fall into the mud pit of "chasing questions" step by step. As far as the current educational form is concerned, review is still a systematic combing of the learned mathematical knowledge and basic skills, and it still requires students to master what they have learned, but its purpose is to make students develop better and lay some foundations for sustainable development.
2. The strategy of review is to make students develop actively and confidently.
In order to make students develop actively and confidently, teachers must be "knowing people", "being good at inducing", "encouraging" and "leading lag".
"Knowing people" is to understand each student's learning psychological state. The ancient educator said: "The teaching method is based on human nature." That is to understand the personality of students; He also said: "Everything is heart-oriented, and people who are not attentive can't do it." In other words, to do a successful thing, psychological intention is an important foundation. If we don't know the students and their attitude towards review, and just let them do their homework and mock exams, students will cope passively, and if they are bored for a long time, they will lose confidence, so this kind of review will only get twice the result with half the effort.
"Good seduction" is to inspire students to recall what they have learned, guide students to summarize and sort out, and connect the knowledge with the same essential attributes before and after, so as to facilitate memory. For some internally related knowledge, guide them to remember the most basic knowledge to reduce the memory burden. For example, a group of common quantitative relations "unit price, quantity and total price", as long as you remember that unit price × quantity = total price, you can deduce the other two relations by multiplication and division, which not only communicates the relationship between knowledge, but also reduces the burden on students.
"Motivation" means encouraging students to be good at independent thinking. Especially for some students with learning difficulties, we should not discriminate, attack or blame them. They must be partial to them, and their progress should be appreciated. We should see that they are developing, so this is also the success of their own education. Students will feel the teacher's expectation and trust. Once they have this feeling, they will be confident and actively participate in review. You know, people are self-motivated, and these students are not naturally complacent and backward.
