Review is a process of consolidating knowledge, systematizing knowledge and improving students' skills. It is an important link in the process of primary school mathematics teaching. Someone said: "Usually, mathematics teaching is to plant a living tree, and the review process is to cultivate a good forest." This sentence fully illustrates the importance of review. Review class is also one of the important classes in primary school classroom teaching, which occupies an important position in primary school mathematics teaching and plays an important role in comprehensively improving students' quality. According to many years' teaching practice, I think that the primary school math review class should do the following:
First, make clear the purpose of review.
1, communication, "networking"
Primary school mathematics teaching network is step by step, spiraling up, with strict systematicness. There is an invisible line between vertical and horizontal knowledge to connect them organically, but the content of mathematics textbooks is completed one by one. Review class is to make students systematize what they have learned through review, and let these knowledge string together vertically and horizontally in students' minds, forming a complete knowledge network system. This can not only deepen the knowledge and consolidate the understanding of the learned knowledge, but also help to store the knowledge blocks in the brain for later use.
2. Cultivate students' ability to organize knowledge.
Review class is not only to guide students to know and attach importance to old knowledge, but also to cultivate students' ability to organize knowledge. By compiling outlines, lists and other methods, the logic of learned knowledge is sorted out, so that the knowledge structure of textbooks is gradually transformed into the cognitive structure of students, and students can initially learn to use different but appropriate methods to embed new knowledge into the cognitive structure.
3. Help students make up for their knowledge defects.
Because of the differences of students' cognitive ability, hobbies and consciousness tendency, their mastery of mathematics knowledge is also different. "Leaking and filling in the gaps" is one of the important methods to discover the truth in review class. In the review class, teachers should combine the students' reality, grasp the situation of poor students, and make up for their knowledge defects in a timely and targeted manner. Through review, we can make up the gap, foster strengths and avoid weaknesses, and at the same time, we can make up for the lack of teachers.
Second, take effective review methods.
1. Make a feasible review plan.
First, make a review plan according to what you have learned and the actual situation of students. Before reviewing, the teacher will comprehensively sort out the knowledge he has taught, systematically classify it, communicate vertically and horizontally, and find out the key points, difficulties and places that students are easy to confuse and cope with. At the same time, make a practical estimate of students' actual knowledge. If the situation is not clear, you can make a written investigation (covering all aspects, highlighting key points and having levels). ), the results will be sorted and analyzed to determine which knowledge can be passed and which knowledge needs to be reviewed. In this way, the review content is determined, the purpose and requirements are defined, and then the appropriate ways and means are considered, so as to make a feasible review plan. To specify a feasible review plan, we should pay attention to the following aspects:
(1) What basic knowledge and skills does this review course include, what are the key points and what are the key points?
(2) Based on the review content of this lesson, how to cultivate students' mathematical ability and habits.
(3) How well do students master the review content of this lesson, which concepts are vague, which problem-solving methods are not skilled, and which of these problems are universal.
(4) How to guide students to review and how to face all students. After making a review plan, the review class can be targeted and get twice the result with half the effort.
2. Let students participate in the whole review process.
Scientific review class should create a review environment in which most students actively participate, reasonably select and arrange knowledge materials, organize students to carry out free and full cooperation and exchange activities, sublimate what they have learned through cooperative interaction and homework operation, and achieve the purpose of consolidating knowledge and developing ability. Let all students take the initiative to participate in the review, which can stimulate students' interest in learning and keep them excited at all times and devote themselves to the review.
3. Choose an appropriate review method
There are many ways to review, such as reading the text, writing an outline, drawing charts, reasoning, giving examples and solving multiple problems. Which review method to choose depends on the specific content of the review and the specific situation of the students. The more ways students review, the more flexible and open their thinking, which is helpful to develop their thinking and improve their creativity.
4. Design a reasonable classroom review mode.
In order to improve the review efficiency, truly face all students, let the students with learning difficulties make up for the lack of previous knowledge, and let the students with spare capacity go to a new level on the original knowledge level, we should consider the trinity review classroom teaching mode combining classroom teaching, group cooperation and individual counseling.
When helping students to sort out and review various knowledge points in a unit or a knowledge block, or to practice by using the concepts, laws and formulas they have learned, the mode of combining group cooperation with individual counseling can be adopted.
