5. Each grade discusses problems such as homework design and workload, usually arranges scientific and valuable homework, and introduces characteristic homework and innovative homework according to the characteristics of students in the class.

2. Summary of mathematics teaching and research activities

This semester, the mathematics teaching and research group is strengthening learning, renewing ideas, establishing the basic ideas of the new curriculum, and unswervingly implementing and cultivating students' innovative consciousness, exploration consciousness and practical ability. "Under the guidance of changing teaching and research concepts, improving teaching and research methods, optimizing teaching and research modes, and actively exploring a new system of primary school mathematics teaching and research under the background of the new curriculum reform, under the correct leadership of school leaders, and with the concerted efforts of all team members Qi Xin, we have carried out a series of activities in a down-to-earth manner and achieved gratifying results.

I. Main Work and Achievements

1. In this semester's mid-term math exam, the average scores of four classes in grade six in regional exams ranked first in the school district. In other years, I exchanged test papers with Betel nut Primary School, and the results reached the standard.

2. Strengthen teaching and research activities to improve teachers' professional ability. Strive for every teacher to have an open class every semester.

3. Strengthen the monitoring of supplementary work. The number of people who have obviously failed is decreasing year by year.

4. Assessed and exchanged the quality of papers and test papers with Binglang Primary School, and the exchange was successful.

Second, the main practices and experiences

The new curriculum standards have injected new life and vitality into the field of education, pointed out the development direction of education and teaching, and fully emphasized the learning status of students. This semester, our teaching and research group regards learning new curriculum standards as an important part of business learning. This semester, many teachers went out of the campus to learn other people's experience and research methods. Our school sent Mr. Ma Yahong to Wuyishan to participate in the seminar on "Problem Solving", which brought new ideas to every teacher. Clear thinking, brand-new framework, clear objectives, and effective learning have a deeper understanding of the basic ideas, design ideas, curriculum objectives, content standards and curriculum implementation suggestions of the new curriculum standards. Under the guidance of the new curriculum standards, the education and teaching reform of all grades in this semester has jumped to a new level. Every teacher is fully aware that it is difficult to adapt to the new situation of education without changing the traditional teaching concept, improving their knowledge level and mastering modern teaching methods.

3. Summary of mathematics teaching and research activities

This semester, under the guidance of the superior leaders, under the direct leadership of the school and the guidance office, combined with the actual situation of our school, according to the various teaching and research plans formulated at the beginning of the semester, we insisted on taking the mathematics teaching classroom as the main position, earnestly implemented the primary school mathematics curriculum standards, paid special attention to the classroom routine education of all grades, and gradually explored a new model of mathematics teaching in all grades. Taking the quality of classroom teaching as the breakthrough point and promoting students' vivid learning as the main direction, we will strive to improve the efficiency of classroom teaching and effectively improve the quality of education and teaching. With the joint efforts of all the team members, a series of activities in various forms have been carried out in a down-to-earth manner, which has steadily improved the quality of mathematics teaching in our school. The busy semester is coming to an end, and the work carried out this semester is summarized as follows:

First, strengthen the routine management of teaching and carry out teaching work in a solid and effective way.

This semester, our group insists on taking teaching as the center, strengthens management, further standardizes teaching behavior, and strives for the organic combination of routine and innovation. Every teacher has a rigorous, solid and efficient teaching style, and strives to cultivate students' good study style of diligence, realism and knowledge. Efforts should be made to embody the people-oriented concept. Teachers can carefully prepare lessons, seriously explore the depth and breadth of teaching materials, pay attention to the guidance of teaching methods and learning methods, study the key and difficult points of teaching in time, carefully design the teaching process in class, and make a good teaching postscript according to their own teaching feelings. Teachers learn from each other, promote each other, do a good job in routine work, do everything in teaching, do a good job in unit clearing and mid-term quality inspection, check for leaks and make up for deficiencies, and cultivate excellent ones to further improve the quality of mathematics teaching.

Second, carry out teaching and research activities to improve the efficiency of classroom teaching.

1, give full play to the advantages of group teaching and research, and strengthen the activities of studying in regular classes and mutual evaluation. Every math teacher participated in the open class of 1 this semester, and held a seminar in time after class. In view of the problems existing in teachers' teaching, the members of the teaching and research group put forward many suggestions for improvement. In the intercollegiate exchange activities with Xia Jie Primary School in Huizhou District, our math teachers have broadened their horizons by listening to lectures, communicating, visiting and studying, and have an intuitive understanding of how to pay attention to students, the classroom, the generation and presupposition in classroom teaching, which has inspired teachers to think deeply.

2, combined with the school district's subject teaching competition, organize open class teaching and research activities and classroom teaching demonstration classes. The participating teachers combine their usual teaching to find out their own "bright spots", which are fully reflected in the practice class. Although some teachers don't take part in class evaluation, they also listen carefully to class evaluation. After the activity, the teachers benefited a lot and were deeply inspired. Although it has been successful, there are still many problems that need to be further explored and improved to make our classroom teaching more realistic and pragmatic.

Three. Specific activities.

1 At the beginning, the teaching and research plan of the mathematics group was made, and the members of each group made the teaching plan of the mathematics discipline.

2. Organize the whole group of open class teaching activities. Every teacher has open classes, lectures and discussions.

3. Teacher Peng instructed students to participate in Zunyi Primary School Language and Numbers League, and Mei Jing won the first prize of municipal mathematics.

4. Conduct three regular teaching inspections at the beginning, middle and end.

5. Organized the mid-term examination of mathematics in the whole school.

6. Organize and guide the final review and conduct the final exam.

4. Summary of mathematics teaching and research activities

Under the guidance of President Fan and the organization of Director Mo, the teaching and research activities of the Mathematics Teaching and Research Group have been carried out vividly. After a semester of teaching and research, the teachers have made progress to varying degrees. This semester's teaching and research activities have benefited me a lot. Let's sum up our own gains and reflections.

First, this semester's teaching and research activities pay more attention to content research and teachers' deep reflection.

Compared with the previous teaching and research that pays more attention to form, this semester's teaching and research pays more attention to the research of content. Although all the teachers involved in teaching and research have teaching experience, they don't study the theoretical knowledge deeply enough and thoroughly enough, and often can't grasp the essence of the problem. In view of this problem among teachers, President Fan gave us a wonderful explanation from the theoretical level. Forty minutes of teaching and research activities will soon end, and there is always a lack of study. At the end of each teaching and research, we will reflect on our own gains and ideas and record them. It is through study and reflection that our math class will be more mathematical.

Second, in-depth study and understanding of new curriculum standards.

After returning from Guopei, President Fan used the time of teaching and research to learn part of the new curriculum standards with us. Through President Fan's popular explanation, our understanding of the new curriculum standards has taken another gratifying step. After deeply understanding the new curriculum standard, in our math classroom competition, more elements in the math teacher's class are integrated into the new curriculum standard, which is the teachers' harvest, which is their understanding.

5. Summary of mathematics teaching and research activities

A semester's work is coming to an end. This semester, the work of the Mathematics Teaching and Research Group in our school continues to be guided by Deng Xiaoping Theory, Theory of Three Represents and Scientific Outlook on Development. Promote the pilot reform of basic education curriculum, strengthen the school-based training of teachers, and comprehensively improve the professional quality of teachers. Taking curriculum reform as the core, paying attention to the main channel of classroom teaching, seeking truth from facts, strengthening the consciousness of reform, innovation and pioneering, and striving to push the education and teaching work of our school to a new level. Now to sum up the work of this semester: teachers are the key to advanced new ideas entering the classroom. Teachers are the implementers of the new curriculum. They practice new courses, implement new courses, implement new courses. More importantly, they become developers, researchers and creators of new courses. Therefore, it is necessary to strengthen the research on teachers' new ideas and promote teachers' leading role, curriculum awareness and skill structure.

1, further update the education and teaching concept. The new educational concept is the premise of the smooth development of the experimental work of curriculum reform, which has injected new vitality into the overall promotion of quality education, and teachers are the fundamental subject of implementing the new curriculum. Therefore, we seriously organize teachers to carry out school-based training and carry out training and learning activities of school counseling once a week and group counseling twice a week. There are special lectures, intensive training, personal self-study and other forms to build a learning platform for teachers and forge ahead with the new curriculum, thus constantly changing teachers' concepts. Based on the implementation of teacher training in the new curriculum of basic education, this paper studies the relevant works such as "Primary School Mathematics Curriculum Standards" and "Mathematics Teaching Methods", and constantly improves the understanding, deepens the development, and takes it into teaching practice, which embodies the new concept of curriculum reform; At the same time, each teacher carefully records, gives timely feedback, exchanges experiences and feelings, and constantly promotes the development of teachers' professional quality.

2. Seriously study and study teaching materials and teaching methods. The curriculum reform advocates students' abilities of active participation, willingness to explore, diligence in practice and cooperation and communication, and highlights the new changes in teaching concepts and methods. We focus on the curriculum reform of basic education and do a good job in the research and analysis of teaching materials. Especially, the teaching materials of experimental grade are analyzed in detail. At the same time, teachers in all classes are also organized to conduct a comprehensive analysis and exchange of teaching materials. We should speak freely, explore and learn, and have the ability to choose and process teaching materials. In this way, teachers can learn from each other, learn from each other, develop together and improve their teaching skills, so as to unite and work together to form a joint force of education.

3. Pay attention to the teaching and research activities of curriculum reform. In strengthening theoretical study, we should explore a new teaching mode with teachers as the main body, school-based research as the carrier and training as the support. Organized and carried out teaching case analysis, focusing on the success and failure, and encouraged teachers to do a good job and summarize and communicate in time once a month. According to the law of cognition, practice-cognition-re-practice-re-cognition, gradually reflect on gains and losses in practice, constantly sum up experience and constantly improve yourself. For excellent reflection, explore new methods and new ways to promote learning. In addition, we also organize teachers to attend lectures and learn advanced teaching methods and means from others. After that, we concentrate on evaluation, analysis, discussion and communication. All the teachers have written good lessons and told me the direction of my future teaching development practically. Everyone agrees that we should make full use of multimedia teaching and attach importance to the cultivation of students' independent exploration and cooperative communication ability. We should be good at creating situations to stimulate students' interest in learning.

6. Summary of mathematics teaching and research activities

This semester, the teaching and research group of our mathematics group has carried out various activities in a down-to-earth and fruitful manner in the conscientious work of all teachers in line with the concept of "serving students and improving themselves". The work of this semester is summarized as follows:

First, strengthen theoretical study and improve professional level.

The content of teaching and research determines the development direction of teachers' professional level and plays a key role in improving teachers' own quality. In the spirit of being responsible for teachers, we hold a meeting at the beginning of the semester to let teachers talk about their inner thoughts and the direction and content that need to be improved, and determine the teaching and research content of the new semester by means of * * * agreement, and write it into the teaching and research plan. In this way, our learning objectives are clearer, the learning content is closer to the needs of our own development, and the effect of "applying what we have learned, applying what we have learned" is truly achieved, and teachers' learning energy is more abundant, which has laid a good and solid backing for teaching and research work.

Second, strengthen daily management and standardize education and teaching behavior.

This semester, our teaching and research group strictly requires teachers to do all routine work in accordance with the system of "preparation, teaching, approval, assistance, reform, examination, thinking and research". Organize relevant personnel to conduct spot checks on the compilation of lesson plans and the correction of homework, and give feedback to each teacher to achieve the effect of learning from each other's strengths. In daily teaching, classes are given irregularly. Adhere to the teaching quality analysis system and organize two quality analysis meetings according to the students' mid-term and final exam results.

Third, carry out school-based teaching and research to promote teachers' professional growth.

1. Conduct joint research activities in the first and second campuses, such as peer cooperation classes and thematic discussions.

2. Adhere to biweekly thematic discussion activities. The theme of this semester is: to stimulate students' interest in learning; Correct students' bad calculation habits; Reflections on the review class. The activities of the teaching and research group have attendance and activity records, which reflect reflection, dialogue and knowledge.

3. Actively participate in joint research activities of regional cooperative schools. This semester, Mr. Zhang participated in the teaching and research activities of the joint school with "mathematical thinking" as the research theme, which was well received by his peers.

7. Summary of mathematics teaching and research activities

The busy semester is coming to an end. Looking back on a semester's teaching and research work, under the correct leadership of the school and the Academic Affairs Office, the Mathematics Group carefully organized the practice of "lecture notes" mode according to the work plan at the beginning of the semester, carried out teaching and research activities with heart, carried out in-depth teaching research, updated the concept of education and teaching, and strived to improve the efficiency of classroom teaching, which achieved good results. The work carried out this semester is summarized as follows:

First, study business and theory with heart, and strive to update the concept of education and teaching.

Theoretical learning combines mass learning with autonomous learning, thematic learning with problem discussion, carefully studies theoretical books such as Mathematics Curriculum Standards and Interpretation of Curriculum Standards, learns new ideas, implements new curriculum standards, broadens horizons, renews concepts and improves one's own quality. In the teaching and research activities of165438+1October 13, all teachers were organized to focus on the students' preview strategies under the teaching of "reading guide" in junior high school mathematics, which played a good guiding role in implementing the teaching mode of "reading guide". This semester, all teachers are carefully organized to participate in the national training program, listen to experts' lectures carefully, and write their learning experiences carefully. They all passed the exam.

Second, do a good job in teaching routine and improve teaching quality in an all-round way.

1. Prepare lessons carefully and optimize the teaching design of lecture notes. The lecture notes were revised and improved for the third time in the seventh grade and for the second time in the eighth grade. In response to the new textbook, the ninth-grade teachers carefully designed the lecture notes for the first time and rationally organized all aspects of teaching, which is more conducive to students' self-learning.

2. Improve classroom efficiency and realize "intensive teaching" and "more practice". Classroom is the main position of teaching. Based on the classroom, according to the students' preview, pay attention to guiding students to understand and digest concepts, theorems, formulas and laws. Pay attention to students' knowledge defects and difficult problems; Correct and demonstrate the problem-solving format; Let students really move in class and take the initiative to solve problems. On the basis of "intensive speaking", let students "practice more", basically ensure that each class has more than 15 minutes of practice time, and consolidate the knowledge of this class through excessive practice.

3. Conscientiously implement the homework guidance link, record the homework status in time, remind the students with problems in time, correct them and gradually improve them. At the same time, strengthen management, put an end to students' plagiarism and correct students' attitude towards homework. Many teachers have also done face-to-face homework, and used the time of self-study class and evening self-study to give individual counseling, which achieved very good results. For example, teacher Li Xiaobin scored significantly higher than other teachers in the final exam.

4, pay special attention to the unit knowledge standard detection, timely detection and analysis, leak detection, and do a good job of combing unit knowledge; Evaluate the test paper in a targeted manner. After every monthly exam in Grade 9, we should pay attention to the evaluation and reflection after the exam and seek ways and measures to improve teaching in time.

8. Summary of Mathematics Teaching and Research Activities

A semester has passed, so I can say that I am very busy and have gained a lot. Generally speaking, the whole group of mathematics teachers conscientiously implemented the school education and teaching work plan, changed their thinking, actively explored the reform of teaching, combined the new ideas and ideas of new curriculum standards with those of mathematics classroom teaching, changed their thinking and actively explored the reform of teaching, and achieved good results.

First, put curriculum standards into teachers' hearts and into the classroom.

How do we teach mathematics? The National Mathematics Curriculum Standard puts forward many new requirements for mathematics teaching content, teaching methods, teaching evaluation and educational values. Undoubtedly, meeting this challenge is a problem that every math teacher must rethink. At the beginning of the semester, organize teachers in this group to participate in the training and study of new curriculum standards and new textbooks. This semester, junior one mathematics has stepped onto a new level under the guidance of the new curriculum standard.

Second, classroom teaching, teacher-student interaction, * * * develop together.

Every math teacher in our group is a practitioner of classroom teaching this semester. In order to ensure the implementation of the new curriculum standards, we regard classroom teaching as a mathematics learning environment conducive to students' active exploration, the overall development of students' emotions, attitudes and values while acquiring knowledge and skills as the basic guiding ideology of teaching reform, and mathematics teaching as a process of interaction and development between teachers and students. Under the leadership of the teaching and research team leader, we will eat in a limited time, closely following the new curriculum standards. Actively use all kinds of teaching resources, creatively use teaching materials to teach openly and listen to comments repeatedly, and refine and improve wonderful cases from research, teaching, listening to lectures and comments. The open class in school has achieved good results, breaking through the closed state of the original subject teaching and putting students in an open, active and diverse learning environment and learning situation. Be affirmed by leaders and teachers.

In addition to preparing lessons carefully before class and writing lesson plans, after implementation, I will review and reflect on my personal experiences or omissions in teaching and write down the highlights or puzzles of students' learning while I still remember them clearly. It has accumulated many useful experiences and inspirations for future teaching. While summing up the achievements, we should constantly reflect on teaching, promote curriculum reform through scientific research, seek development through innovation, constantly extend the essence of open classes to daily teaching practice, strive to deal with the connection between mathematics teaching and real life, strive to deal with the importance of application consciousness and problem solving, and attach importance to cultivating students' awareness and ability of applying mathematics. Attach importance to cultivating students' inquiry consciousness and innovation ability.

Third, innovate evaluation to encourage and promote students' all-round development.

We regard evaluation as a means to comprehensively examine students' learning situation, stimulate their enthusiasm for learning and promote their all-round development, and it is also a powerful means for teachers to reflect on and improve teaching.

The evaluation of students' learning not only pays attention to students' understanding and mastery of knowledge and skills, but also pays attention to the formation and development of students' emotions and attitudes; We should not only pay attention to the results of students' mathematics learning, but also pay attention to their changes and development in the learning process. Grasping the mastery of basic knowledge, grasping the openness of classroom work, combining qualitative and quantitative methods, adopting grading system for quantitative and commenting form for qualitative, paying more attention to what students have mastered, what progress they have made and what abilities they have. The evaluation results are conducive to establishing students' self-confidence in learning mathematics, improving their interest in learning mathematics and promoting their development.

9. Summary of Mathematics Teaching and Research Activities

There are 42 high school classes in our school. There are 23 math teachers and senior teachers 17, with a large number, high professional titles and strong ability.

(3) Teacher Zhang Shengli won the grand prize in the problem-solving competition for senior high school math teachers held by the Municipal Teaching and Research Office.

(4) In the activities organized by the school, three senior high school math group leaders and four young teachers participated in the open class, and the teachers in the group actively attended and evaluated the class, which fully reflected the theme of "standardizing the class", promoted everyone's thinking and improvement, and gave all teachers a platform to learn from each other, achieving the expected goal.

10. Summary of Mathematics Teaching and Research Activities

On Tuesday, our county organized a mathematics teaching and research activity of teaching quality analysis and curriculum reform discussion. Teacher Zhang, a researcher, gave an important explanation and guidance, which benefited me a lot. Here's my experience:

1. Rational development and integration of teaching content

Content is the carrier of teaching, and mathematical thinking method is its soul and core. For teachers, as users of curriculum resources, we should carefully analyze the mathematics content in textbooks, select and apply the textbook content according to the needs, and make the curriculum content more closely combined with students' mathematics activities, which is more conducive to the infiltration and edification of mathematical thinking methods.

2. Experience and understand ideas through activities.

Mathematical thinking method is the key to teaching. The thinking process of teaching methods is fully exposed in the classroom, so that students can participate in teaching practice and give full play to the main role. In the teaching process, we should make use of the teaching aid triangle around students, apply origami and the grid behind textbooks, so that students can actively participate in the process of mathematics teaching in a positive state. In the process of thinking, doing and speaking, students can gradually understand the mathematical thinking method according to their own experience.

3. Cultivate students' awareness of active application.

Judging from the characteristics and formation process of mathematical thinking methods, the infiltration of students' mathematical thinking methods can not be achieved overnight, but needs a process of continuous infiltration, step by step, from shallow to deep. In this process, teachers need to be an intensifier of "process" and constantly "knock" students' thinking with mathematical ideas, so that students can constantly reflect, accumulate, feel and clarify in the process of "knocking" again and again until they can take the initiative to apply. Therefore, in teaching, I pay great attention to emphasizing students' application of analogy and the combination of numbers and shapes, and should "reflect" after solving the problem, so as to realize the application value of mathematical thinking methods in the process.

In a word, this activity is a valuable learning opportunity for me and I feel a lot. I hope I can participate in such activities more, learn from others' strengths and constantly improve my professional level. At the same time, it also made me realize that the space for career growth is infinite, maturity is relative and growth is absolute. This also requires persistent study and hard practice in long-term education and teaching practice, so as to continuously improve and grow as soon as possible.
