Solid and effective mathematics teaching and research activities are the key to effectively complete mathematics teaching tasks. Only by strengthening learning, concentrating on scientific research and carrying out mathematics teaching and research activities in various forms and angles can teachers better promote their professional growth and improve the efficiency of classroom teaching.

Effectively carrying out mathematics teaching and research activities is an effective means to improve the professional level of mathematics teachers and promote the smooth implementation of mathematics teaching in schools. Primary school mathematics teaching and research activities should be guided by the concept of new curriculum standards and actively carry out characteristic teaching and research activities with brand-new thinking and colorful forms. The author believes that "the effective development of mathematics teaching and research activities" should be carried out from the following aspects:

First of all, strengthening theoretical study is the basis for effectively carrying out mathematics teaching and research activities.

The premise of carrying out mathematical teaching and research activities is that teachers should have a certain level of mathematical theoretical knowledge, study and study the theoretical ideas about mathematics, reserve necessary "mathematical nutrients" for teaching and research activities, and improve teachers' own mathematical literacy, so as to better carry out mathematical teaching and research activities. There is only one thing that teachers must do if they want to reserve certain "mathematics nutrients" for mathematics teaching and research activities, and that is learning. Therefore, teachers should read more books on mathematics teaching in their spare time, concentrate on reading educational theory monographs related to mathematics, arm themselves with advanced educational ideas through reading, constantly innovate teaching methods, reflect on their teaching practice, constantly update teaching concepts and methods, and realize the creation, dissemination and application of knowledge. Learning can take the form of "three decisions" and assign people to a fixed time and place. For example, the study of each teaching and research group in the school is organized and arranged by the head of the teaching and research group, and the study plan is written from the beginning. Students can be arranged to study and train after school every Tuesday afternoon. Trainers can take turns to learn some excellent cases of famous teachers and watch excellent class CDs. And learn the excellent articles they got from their usual reading materials. After studying, every teacher should write his own experience and exchange experiences in the following study. In addition, teachers can make their own personal self-study plan, according to the plan, how many articles to read, how many cases to write, how many experiences to exchange and so on.

Secondly, the establishment of scientific research team in mathematics discipline is the guarantee to effectively carry out mathematics teaching and research activities.

Effective mathematics teaching and research activities not only refer to holding several evaluation classes, demonstration classes, observation classes or seminars, but also make mathematics teachers grow rapidly in all aspects and make teachers' classroom teaching efficient through the development of teaching and research activities. In order to make mathematics teaching and research activities more effective, in addition to school-based teaching and research, we should also carry out some theoretical and practical research related to mathematics, that is, subject research. This requires us to pay attention to finding and accumulating problems in the usual mathematics classroom teaching, and solve problems when there are problems. In the face of problems, we should constantly explore and study to find the best way and method to solve them. Project research is an important part of teaching and research activities. The purpose of the study is to solve the problems existing in education and teaching and strive to maximize the benefits of education and teaching activities. Mathematics teaching and research groups of all grades in the school should determine the research topics of the teaching and research groups according to the actual situation of their grades, organize teaching and research activities according to the topics, and carry out teaching practice. For example, in recent years, our school has determined such topics as "exploration and research on teaching methods of computing in lower grades", "exploration of teaching methods of graphics in middle grades" and "exploration and research on efficient classroom thinking of mathematics in higher grades". These topics are arranged in the mathematics teaching and research group. The form of subject research adopts the way of subject research. In the process of experimental research, research reports are submitted to the Academic Affairs Office regularly, and the Academic Affairs Office organizes or invites mathematics professionals to discuss and evaluate them. This not only improves the enthusiasm and initiative of all math teachers, but also develops the teachers themselves. More importantly, students have become the biggest beneficiaries of research, which really highlights the maximization of the benefits of education and teaching activities.

Thirdly, various forms of teaching and research activities are the carriers of effective mathematics teaching and research activities.

Teaching and research must be put into teaching and research activities to study, explore and verify. Various forms of teaching and research activities are the carriers of effective mathematics teaching and research activities. After several years of research and practice, I think the following activities are helpful to the efficiency of mathematics teaching and research activities.

1. Prepare lessons collectively

Years of teaching practice have proved that there is no ready-made experience to follow in teaching, and the valuable experience just gained will soon become outdated. Moreover, it is time-consuming and laborious to fight alone based on personal experience, and it cannot solve substantive problems. The new curriculum reform actively advocates students' cooperative learning, and also requires teachers to cooperate and explore, form a discussion atmosphere, and give play to the advantages of "group effect". As an effective form of teachers' cooperative discussion, collective lesson preparation plays an important role in exerting teachers' teamwork spirit, brainstorming and learning from each other's strengths. Only by strengthening collective lesson preparation, giving full play to collective wisdom, learning together and making progress together can the effectiveness and efficiency of classroom teaching be improved.

2. Different in the same class

As the saying goes, "A thousand readers have a thousand Hamlets". Different teachers' thoughts, experiences, outlook on life and values determine different understandings of the same content. Every teacher has different understanding, different ideas and different teaching methods for the same content. This difference between teachers is a good teaching and research resource. Therefore, we can hold some heterogeneous activities in the same class to study and discuss new ideas and methods of mathematics classroom teaching. Only in this way can we learn from each other in comparison and improve together in comparison. The procedures adopted are as follows: ① each mathematics teaching and research group in the school determines a teaching topic according to the grade segment; ② Some teachers in the teaching and research group prepare lessons separately; ③ Teachers attend classes; (4) The teaching and research group collectively attends lectures and evaluates classes; Teachers learn from others' experiences and practices in teaching and learn in open and diversified teaching and research activities, which is conducive to forming their own teaching characteristics and styles.

3. Topic discussion

Lesson discussion is a form of collective research conducted by the teachers of the research group after class. At present, the ten-step topic discussion activity proposed by the county teaching and research section is adopted. In other words, teaching consultation will find problems, sort out problems, set themes, make clear theoretical research, prepare lessons collectively, find ways, everyone will see the actual effect, reflect on the gains and losses personally, share with peers, improve professional guidance, refine knowledge into routines, and problems will lead to new topics.

4. Centralized analysis of case fragments

Case fragment analysis is very important for teachers to improve their teaching level. It is the reappearance of classroom teaching scene, and it is a method to gather everyone's wisdom to help everyone improve classroom teaching. Finding and solving problems in the analysis not only applies the theory, but also produces new teaching experience. This aspect is held once a month, and teachers are required to put forward confused problems or cases in classroom teaching, analyze them in depth, and find out the solutions and the best ways.

Fourthly, broadening the scope of teaching and research activities is to carry out and popularize effective mathematics teaching and research activities.

Over the years, there have been problems in the mode of teaching and research activities in primary schools, and the effect of the activities has been greatly reduced. In view of this, our school has explored several feasible forms of activities.

1. Joint film teaching and research (schools join hands)

Effective mathematics teaching and research activities are not closed, but open. The development of school-based teaching and research needs certain conditions, such as the guidance of experts, the mutual assistance between experts or academic leaders and peers, and a certain number of high-level teachers. Rural schools are often small in scale and poor in conditions, so it is difficult to carry out school-based teaching and research. In order to overcome this problem, through research and practice, inter-school cooperation and interactive teaching and research have effectively promoted the professional development of teachers. In practice, the formation of "regional promotion, regional interaction; Combine centralized guidance with fragmented services, learn from each other's strengths and improve together.

Step 2 exchange experiences

Pay attention to the role of the school district center group, carry out participatory communication, interactive communication and thematic communication, and form a three-dimensional interactive and pragmatic teaching and research form. In this way, teachers participate in a wide range, which not only increases the intensity of inter-school exchanges and cooperation, but also verifies the effectiveness of school-based teaching and research. Achieved the goal of complementary advantages and common improvement.

The purpose of teaching and research activities is to solve the problems existing in mathematics classroom teaching, explore new mathematics teaching methods, improve mathematics teachers' classroom teaching level and serve teaching practice. Therefore, every teacher in the school has a mission, which is to promote the improvement of students' ability by improving themselves. Only by studying, understanding and applying theories can we serve teaching and students better.
