Summary of key lectures in mathematics

The two-speaking class is very clear on the students' completion of the test papers. It can collect the wrong feelings and analyze the wrong reasons; it can promptly encourage students; the test papers emphasize the key points, correct the mistakes, strengthen the skills, and increase the students' mistakes. Compensation exercises.

Aspects for improvement in the two classes: 1. The test papers should be interspersed with the test training, including the skills of the questions and the psychology of the test. 2. The best part of the evaluation class is as follows: students are independently corrected, students discuss each other, teachers explain and dial, student corrections, teachers give detailed answers, necessary compensation exercises, students' independent summary and attention.

For the four sections of the “same class” class, the four teachers have their own characteristics and different styles, all of which adopt the case study guide.

The main content of the case designed by Mr. Liu Guangrui is clear and clear, highlighting the foundation, highlighting the hot spots, setting the hierarchy, and selecting the topic. The students in the classroom are active, the teachers pay attention to guidance, and the treatment is delicate. There is also a review feature. When the basic knowledge of the students is not very good, this kind of teaching is very effective.

The course “Before the Course” designed by Mr. Fu Zhenkai has made the basic knowledge exercises and embodies the use of knowledge. The typical examples are selected, which incorporates mathematical ideas such as combination of numbers and forms, classification and discussion, transformation and returning, and the ability to think and operate. The ability training is in place, covering the hotspots such as derivative, quadratic inequality, absolute value inequality, and tick function. The typical examples are student board performance, teacher problem guidance and detailed process through multimedia presentation. All students actively participated in the classroom and their emotions were high, which was in line with the characteristics of the second round of review.

The students used by Xie Shikui and Sun Yong are the same. The students in the class are poorly based. The key knowledge of the two people is based on the knowledge points. After a brief review of the content of the case, Mr. Xie added the test feedback in the classroom, using multimedia projection to cast, and the students should be completed one by one, but the difference in the students is not enough, the efficiency is low, and the group placement efficiency will be higher. Teacher Sun’s entire class is for students to play on the blackboard, and then explained by the students. This does fully mobilize the students’ enthusiasm, but the student’s case has been completed under the class. Low, in addition to the performance of some students, although the steps are too complicated, teachers do not have guidance and guidance.

The reason why the "same class is heterogeneous" is so different is mainly caused by the difference of the target, the understanding of the academic situation, the grasp of the key points, and the personal concept. The study of "same" in "same class heterosexuality" should be more important than the study of "different". The study of "different" should be carried out around "the same". In the second round of review, the "same class is heterogeneous", teachers should pay special attention to Emphasis should be placed on in-depth study of teaching content and positioning of teaching objectives, rather than focusing on finding innovative teaching strategies and teaching methods that are “heterogeneous”. Teachers should not be taught in the “heterogeneous” The direction.

In the communication session, Mr. Liu Guangrui from Wucheng No. 2 Middle School put forward the idea of ​​“four links and three exercises” for the second round of reviewing the case study.

The mathematics teaching and researcher Yang Changzhi made a request for the second round of review. For the special review class,

1. Guide the students to review the class as soon as possible after five minutes after class with 3-5 questions;

2. Form a network for the basic knowledge of this section, and analyze the easy-to-mix points and error-prone points;

3. For the test points in this section, give three or more examples, and supplement the corresponding variants. The lesson will focus on one example, explain and play, and the other topics will be completed by the students;

4. Each class should ensure that students have a limited time training time of about 10 minutes.

For the lecture requirements:

1. Allow students to score non-intellectual factors in advance, from the unclear concept, knowledge forgotten, operational errors, carelessness, improper strategy, logical confusion, etc. to summarize the reasons for loss, correct errors, compare actual scores and should The difference in scores;

2. Conducting the analysis of the test in the class, from the difficulty of the topic, the situation of the student's examination, etc., to praise the main, improve students' self-confidence;

3. Group discussion, we must regularly set the content to discuss the topics that need to be discussed, and deepen the impression;

4. Teachers classify and return, focus on commenting, in the process of speaking, it is necessary to point out the fundamental mistakes in the students' problem solving, and focus on solving the problem of "can't be right, not complete, not beautiful" in solving problems;

5. After the lecture, the student is told to be kind to the wrong question, and pay attention to the familiar and mid-range questions.

The teachers selected by the event have rich teaching experience and high teaching level, and are highly praised by local teachers . The local teachers of the same school participate in the same class and have high enthusiasm. The teachers of the same subject participate in the “same class” activities and the teachers who attend the class. By comparing and knowing which method is more efficient in classroom teaching, it is beneficial for teachers to learn from and promote teachers to change their minds. It is hoped that such activities will be held for a long time.
