Tisso

I. Guiding ideology

Guided by the main points of school work and based on mathematics curriculum standards, we will deepen teaching reform and promote students' all-round, sustained and harmonious development. With the goal of improving teaching quality, we should standardize teaching behavior, strengthen the investigation and monitoring of teaching quality, actively promote quality education, strive to improve the mathematics quality of all students and promote the improvement of professional level.

Second, the work objectives

1. Cultivate students' interest and good habits in learning mathematics.

Interest in mathematics learning is very important for mathematics learning. In this semester's teaching, I should pay attention to stimulate students' interest in learning and organize students to carry out various learning activities by using the materials provided by textbooks. In teaching, we should first attach importance to the enthusiasm of students to participate in learning activities and encourage them to actively participate. We should pay more attention to students' speeches. More importantly, students should not be trained in a unified and stylized language, but should be allowed to express their ideas in their own language. Let every student like the class first, like the teacher, and then like learning math.

2. Let students learn mathematics in vivid and concrete situations.

In teaching, I want to make full use of students' life experience, design vivid, interesting and intuitive math activities, such as telling stories, playing games, intuitive demonstrations, simulated performances, etc., to stimulate students' interest in learning, let students understand and know math knowledge in vivid and concrete situations, and encourage every student to start, talk and use their brains to participate in the learning process of mathematics.

3. Guide students to think independently and cooperate with their peers.

Independent thinking and cooperative communication are important ways for students to learn mathematics. In teaching, teachers should encourage students to think, express their views and communicate with their peers in specific activities. In the process of thinking and communication, provide appropriate help and guidance, select valuable questions or opinions from students, and guide students to discuss in order to find the answers to the questions. I should consciously cultivate students' desire and habit of communicating with others, so that students can gradually learn to describe their ideas in an appropriate way and learn to listen to others' opinions.

4. Cultivate students' ability to initially ask questions and solve problems.

We should pay attention to cultivating students' awareness and ability to ask questions, and set up columns such as "Problem Bank" to encourage students to ask questions. Even if some problems cannot be solved for a while, they can be solved after the "problem bank". In teaching, I should make full use of students' existing knowledge and experience, guide students to apply what they have learned to life at any time, solve the math problems around them, and try to find math problems from daily life, understand the role of mathematics in real life, and realize the importance of learning mathematics.

Thirdly, the analysis of learning situation.

There are X students in my class, and their learning attitudes and class learning atmosphere are relatively good. I have always attached great importance to the cultivation of behavior habits, so these students have a correct learning attitude and write their homework neatly and beautifully. However, due to the disjointed family education, some students are not strict with themselves at ordinary times, and their study habits are poor, their homework is sloppy and their handwriting is scrawled, which leads to unsatisfactory academic performance. Therefore, in the process of mathematics teaching this semester, we should fully tap students' potential, give full play to students' main role and teachers' leading role, especially strengthen the cultivation of students' study habits and sense of responsibility, learn thinking methods, develop good thinking habits, and infiltrate the cultivation of students' innovative consciousness and practical ability into the whole teaching process.

Verb (abbreviation of verb) teaching strategy

In this semester, to continue to improve the quality of teaching, I think we should start from the following aspects:

1. Pay attention to students' non-intelligence factors, stimulate students' learning enthusiasm through the mechanism of praise and encouragement, and strive to cultivate students' good behavior habits and study habits.

2. Do a good job in teaching routine, learn all kinds of materials with an open mind, strive for the cooperation of parents with a serious and responsible work attitude and enthusiastic work style, and do a good job in cultivating students.

Intransitive Verb Counseling Scheme:

1. Pay attention to teaching students in accordance with their aptitude, further improve the quality and make up for the differences. Let gifted students pair up with students with learning difficulties to achieve the goal of working together.

2. Pay more attention to the students with learning difficulties in the classroom, ask targeted questions, find out their learning difficulties and solve them.

3. If you want to do both ends well and leave the main points in the middle, you should try your best to design teaching methods so that top students can eat well, middle students can eat well and poor students can eat well. Pay attention to selectivity in designing problems, designing exercises and analyzing contents. At the same time, it is clear that the difficulty of the exercise questions is hierarchical, so that students have clear goals. You can complete the exercise in a short time.

4. Pay attention to the correction of poor students' wrong questions and help them finish the basic homework repeatedly until the students really understand it; Ensure that poor students' homework is corrected face to face.
