How to have a good math class is very familiar to every math teacher. However, how to teach every math class well, let students master knowledge to the maximum extent in class and improve their math scores really needs our careful design. We should not only strive for perfection in content, but also conduct in-depth research on stimulating students' interest and passion in learning. Through my years of continuous teaching practice, I have the following feelings.

First, teaching is an art, and preparing lessons well is the basic condition for doing a good job in art.

An unarmed soldier can only surrender when he goes to the battlefield; Teachers who are not fully prepared to go to the podium are at best "talking nonsense", far from the ability to control the classroom. So, what is a lesson?

1. Prepare a starting point.

The so-called starting point is the growth point of new knowledge on the basis of original knowledge. A suitable starting point is conducive to promoting knowledge transfer and enabling students to learn and be willing to learn. The starting point is too low, students are not interested and unwilling to learn; The starting point is too high for students to understand and learn.

2. Be prepared for the key points.

Emphasis is often the starting point and main part of new knowledge. Give prominence to the key points when preparing lessons. In a class, first of all, we should ensure that the key contents are focused in time, closely focus on the key points, and take this as the center, supplemented by knowledge and practice, to guide and inspire students to strengthen their understanding of the key contents, so that the whole class has a soul.

3. Be prepared for difficulties.

The so-called difficulty is the knowledge point that most students in mathematics can't understand and master. Difficulties and priorities sometimes coincide. When preparing lessons, it should be determined according to the breadth and depth of the teaching materials and the students' foundation. We must pay attention to analysis, study carefully, grasp the key points and break through the difficulties.

4. Prepare to cross the intersection.

That is, the connection point between old and new knowledge. Mathematics knowledge itself is very systematic, and chapters, examples and exercises are closely related. Only by truly understanding the intersection of old and new knowledge can we integrate knowledge, communicate the vertical and horizontal links between knowledge, form a knowledge network, and let students draw inferences and use knowledge flexibly.

5. Be prepared for doubt.

It is that students are easy to mix and make mistakes. When preparing lessons, we should combine the students' basic and practical ability, find out the doubts and make full preparations.

Second, teachers should give full play to students' initiative, enthusiasm and creativity according to their characteristics, create the best educational methods and methods, overcome their own shortcomings and educate students to develop in the best direction. Do not choose students who are suitable for education, but create education suitable for students' optimal development.

1. Understand students and analyze students.

Teachers should analyze students' living habits, family natural conditions, learning attitude, learning ability, personality, friends and hobbies, physical condition, etc. , so as to comprehensively and objectively understand students and know them. And through observation and understanding, careful analysis and comparison, summed up the students' personality characteristics, learning characteristics and behavior habits. This is the starting point of creating an education suitable for students' optimal development.

2. Find the problem and master the excitement.

Through the understanding and analysis of students, teachers can find problems and grasp the staged and temporary physiological and psychological changes of students, so as to grasp the excitement center and excitement point of students at a certain stage, a certain period or even a certain moment. Communicate with students frequently and learn first-hand materials from them. Be diligent in learning, asking questions, walking, observing and thinking, so as to design the best and most suitable educational methods. This is the basis of creating an education suitable for students' optimal development.

Third, optimize classroom teaching.

The optimization of classroom teaching mode has four characteristics:

1. appropriately increase students' thinking ability.

2. Pay attention to the compilation of teaching language.

3. Put questions throughout the classroom teaching.

4. Practice in class in time.

In order to provide a relaxed and lively environment for classroom teaching, the methods are as follows:

1. Students are not required to copy notes, let alone check their class notes. What really needs to be written down only needs to be written on the corresponding page of the book. Students are required to listen carefully and take the initiative to participate in speeches and questions.

2. The focus is on the "speaking" class. Explain concepts and examples clearly, thoroughly and vividly. In the new course, it is forbidden to add examples at will, especially when students have not understood and mastered new knowledge. Increasing the difficulty of knowledge points at will suddenly cause students' disgust and fear of what they have just learned, which is not worth the candle.

3. Practice in class in time, so that students can use new knowledge to solve problems accurately, feel happy and have confidence in themselves.

4. Lectures should grasp the essentials of knowledge and have a clear context. In particular, it is necessary to explain clearly the application, contact with life, contact with productive labor and contact with science and technology, so that students can constantly establish a clear purpose of learning mathematics.

5. Be good at using humorous language and give appropriate examples to make it suitable for students' age. Learning is a pleasure, not a burden.

At present, classroom teaching is still the main channel of school education. I attach great importance to the continuous reform and optimization of classroom teaching, emphasizing the scientificity and objectivity of classroom teaching. Even if students master basic concepts, basic principles, basic laws, basic skills and problem-solving strategies, they will have a preliminary scientific consciousness and attitude. I also emphasize the humanity and sociality of classroom teaching, cultivate students' self-confidence and self-control, cultivate positive personality, pay attention to students' inner experience of classroom teaching activities, and pay attention to the integration of knowledge, intelligence, emotion and behavior. So as to stimulate students' interest in learning mathematics and improve their academic performance.
