According to the forgetting curve drawn by German psychologist Ebbinghaus, students forget knowledge regularly, and through effective memory, they can deepen their understanding of knowledge and master its internal relations. It is an effective method to guide students to recall and sort out the review content by filling in the blanks, tables, block diagrams and knowledge network structure, and to straighten out the internal relationship of knowledge from a certain angle.

When preparing lessons, teachers should not turn the above questions into simple fill-in-the-blank questions, but also synthesize them appropriately and give guidance and guidance on key points. In teaching, we should try our best to guide students to recall all the knowledge points independently. When they really can't remember, they should turn to the textbooks to find the answers. In this way, students can review and sort out the basic knowledge and skills they have learned comprehensively and accurately through their own independent thinking. This is mainly for students to clarify the internal relationship of knowledge, form a network structure, and make a good knowledge reserve for solving the following problems. It is the process of internalization and construction of knowledge, which is much better than the teacher's simple narration.

Second, the basic knowledge detection link

In the review stage, a lot of content is the presentation and application of old knowledge. However, many students are "low-minded" and understand it as soon as they listen in class, but they make mistakes after class. At the same time, they feel that the review class is very boring, which greatly affects the effect of the review class. Therefore, increasing the detection and evaluation of the classroom will achieve good results in overcoming these difficulties. After recalling the basic knowledge, you can arrange 1-5 exercises to fill in the blanks. The purpose is to test the students' mastery of knowledge, and the second is to pave the way for the following examples through the simple application of knowledge. For example, after reviewing Pythagorean theorem, we can give two right-angled sides to find the hypotenuse, the right-angled side and the hypotenuse to find the other right-angled side, and the two sides are known to find the third side (in two cases), and then we can use Pythagorean theorem to solve simple practical problems such as the ladder leaning against the wall. Through classroom comments, it is helpful to improve the review effect, not only to clearly understand the students' mastery, but also to stimulate students' interest in learning.

Third, the typical example explanation link

We know that the purpose of problem-solving teaching is not only to solve the problem itself, but to let students explore and master the general strategies and methods to solve the problem and gain emotional positive experience. Mastering mathematical thinking method is the soul of mathematics teaching. We should give full play to the role of typical cases, reactivate students' curiosity and challenge in class, and avoid the tactics of asking questions about the sea.

1, easy to talk to

2, Chen topic new talk

Step 3 make a mountain out of a molehill

Some examples, especially some choices and fill in the blanks, are easily overlooked. In fact, they are rich in connotation. If we can dig deep and make good changes, we can often draw inferences and even draw a picture.

4. Tell me more questions.

Some examples are similar in graphic structure, problem background and solving methods, and even some problems are based on the same problem, but the conclusions are different. Therefore, it is necessary to solve many problems with one problem, which can make students feel that as long as the connotation and extension of the problem are thoroughly excavated and then applied flexibly, many problems can be solved with the same core knowledge and methods, which can make students more confident in math review and avoid being reviewed by a large number of materials.

5. A problem is changeable.

In some cases, taking the opportunity to guide students to extend and popularize appropriately can stimulate students' desire for knowledge and cultivate students' good habits of independent exploration, which is undoubtedly a good strategy for students to get rid of the sea of questions in the tense review stage. If our teachers pay attention to this research in their usual review and lesson preparation, it will certainly play a positive role in improving students' grades and cultivating their abilities in a short time.

6. Shallow talk about deep topics

Some examples are novel and difficult to synthesize, and students are often at a loss. Therefore, when teaching examples, we should find the breakthrough point according to the characteristics of the topic, skillfully reduce the difficulty, make the big topic small, and make the deep topic shallow, so that students can suddenly understand.

Fourth, the classroom detection link.

1, pay attention to the change and serialization of exercise items to avoid a large number of repeated mechanical exercises.

2. Pay attention to the evaluation and feedback of the results of learning practice, and correct and make up for the defects and deficiencies exposed in it in time.

Fifth, the class summary link.

This is a summary of the whole class system, and it is the foothold and destination of all teaching activities. Generally include:

1, standing at the height of the whole middle school mathematics system, summarize the review content completely.

2. Summarize mathematical thinking and methods, and explain the scope of application and problems that should be paid attention to.

3. The problems exposed in the review process should be repeatedly emphasized, and if necessary, some targeted topics can be selected for extracurricular exercises.

Of course, although some efforts and attempts have been made to strengthen the effectiveness of the ninth grade math review class, there is still a long way to go to achieve a higher level of "effectiveness". In the future, I will continue to work hard, constantly improve, and strive to make the ninth grade math review class high-quality and efficient.
