1. Relevant definitions of effective mathematics teaching in curriculum standards
Mathematics Curriculum Standards for Full-time Compulsory Education (Revised Draft) points out that mathematics activities are a process of mutual participation, communication and interaction between teachers and students. Effective mathematics teaching activities are the unity of teachers' teaching and students' learning, students are the main body of mathematics learning, and teachers are the organizers and guides of mathematics learning.
2. On the definition of "classroom teaching effectiveness" in the research.
The research group believes that the effectiveness of classroom teaching means that students have completed their learning tasks with the guidance, organization and help of teachers, and achieved the expected progress and development. Among them, development includes the development of three dimensions in three-dimensional goals; The development of students' wisdom; Reproductive development; Future-oriented development. To improve the effectiveness of mathematics classroom teaching is to carry out mathematics classroom teaching as little as possible, so that students can complete their learning tasks and get more progress and development.
(B) the purpose and significance of the study
The effective teaching of primary school mathematics classroom should be to carry out classroom teaching as little as possible, so that students can complete their learning tasks and get more progress and development. However, in the classroom observation of primary school mathematics, we found that many teachers' teaching behavior is different from the new curriculum concept, and the classroom teaching efficiency is low. The main manifestations are as follows: the teaching goal is unclear, the focus is not prominent, the "result" is emphasized over the "process", the practice is not accurate enough, and the result is half the effort; Students' dominant position is not prominent enough (such as "independent inquiry" is not enough, the process of "cooperation and communication" is short, and the participation of all staff is not enough); Insufficient academic ability training, students' learning ability is not strong; Classroom evaluation is superficial and lacks guidance and encouragement. In order to solve these problems, combined with the "2009 Project Guide of the Eleventh Five-Year Plan of Yunnan Educational Science Research", we conducted a study on "Improving the effectiveness of classroom teaching of mathematics in primary schools". This study focuses on the long-term development of students, constructs scientific and reasonable teaching values with students as the main body, and explores operational strategies to improve the effectiveness of primary school mathematics classroom teaching, thus improving the effectiveness of primary school mathematics classroom teaching, guiding primary school mathematics teaching practice in a wide range, and further improving the quality of primary school mathematics classroom teaching. It is a research with strong pertinence, maneuverability and practical significance.
(3) Research contents and assumptions
1. Research content
(1) Learn relevant theories and existing research results, and seek the core idea of this study;
(2) Rational analysis of inefficient behavior in primary school mathematics classroom teaching;
(3) Explore the operational strategies to improve the effectiveness of primary school mathematics classroom teaching.
2. Research hypothesis
The research on improving the effectiveness of primary school mathematics classroom teaching can not only transform the relevant systematic research results at home and abroad into the research on improving the effectiveness of primary school mathematics classroom teaching, but also realize the transformation and appreciation of the existing research results, providing reference for the research on the effectiveness of classroom teaching in other disciplines, thus promoting the research on the effectiveness of classroom teaching in other disciplines. It is a research with strong pertinence, maneuverability and practical significance.
Second, the research background and literature review
(A) related research results
The idea of effective teaching abroad originated from the scientific teaching movement in the west in the first half of the 20th century. The more influential teaching theories and models in the West include Vygotsky's theory of children's proximal development zone and optimal teaching stage, zankov's theory of teaching and development, babanski's optimal teaching and Bloom's theory of target classification. From this, we can explore the effectiveness of teaching. The research on effective teaching in China began in the second half of 1990s, and the most representative one is Professor Cui Yunkuo's Ideas and Strategies of Effective Teaching. Professor Cui clearly defined the connotation and core concept of "effective teaching" and put forward the concept of effective teaching. There is also Professor Ye Lan's experimental report on "New Basic Education" and its reconstruction of teaching values, teaching process and teaching evaluation, which provides extremely valuable theoretical and practical basis for the study of effective teaching. However, looking at the research at home and abroad, most of them focus on macro-theoretical research, which can be directly used to guide the relatively micro-operational strategy research of improving the effectiveness of primary school mathematics classroom teaching, and further exploration is needed by colleagues. Based on this, we put forward the research topic of "Improving the effectiveness of primary school mathematics classroom teaching", focusing on the operational strategies to improve the effectiveness of primary school mathematics classroom teaching, with a view to guiding primary school mathematics teaching practice in a wide range and further improving the quality of primary school mathematics classroom teaching.
(B) the theoretical basis of the study
1, mathematics curriculum standard for full-time compulsory education
Mathematics Curriculum Standards for Full-time Compulsory Education (Revised Draft) points out that mathematics activities are a process of mutual participation, communication and interaction between teachers and students. Effective mathematics teaching activities are the unity of teachers' teaching and students' learning, students are the main body of mathematics learning, and teachers are the organizers and guides of mathematics learning. Mathematics teaching activities must stimulate students' interest, arouse their enthusiasm and stimulate their thinking; Attention should be paid to cultivating students' good study habits and mastering effective learning methods. Students' learning should be a lively, active and personalized process. In addition to learning, hands-on practice, independent exploration and cooperative communication are also important ways of mathematics learning. Students should have enough time and space to experience activities such as observation, experiment, guessing, verification, reasoning, calculation and proof. Teachers' teaching should be based on students' cognitive development level and existing experience, face all students, pay attention to heuristic and teach students in accordance with their aptitude, and provide students with sufficient opportunities for mathematics activities. We should properly handle the relationship between teachers' teaching and students' autonomous learning, take effective measures to inspire students to think, guide students to explore independently, and encourage students to cooperate and exchange, so that students can truly understand and master basic mathematical knowledge and skills, mathematical ideas and methods, get necessary mathematical thinking training, and gain rich experience in mathematical activities.
2. Cui Yunkuo's theory of "effective teaching"
Cui Yunkuo believes that effective teaching pays attention to students' progress or development, and teachers must establish students' dominant position and establish the idea of "all for students' development"; Effective teaching pays attention to teaching efficiency and requires teachers to have the concept of time and efficiency; Effective teaching pays more attention to measurability or quantification, such as making teaching objectives as clear and specific as possible; Effective teaching requires teachers to have reflective consciousness; Effective teaching is also a set of strategies.
3. Vygotsky's theory of "zone of proximal development"
Vygotsky believes that children's psychological development has two levels, namely, the existing level of development and the "zone of recent development". "Teaching should be ahead of development" and "Teaching creates the nearest development zone". Teaching can only promote the development of students by starting from the individual differences of two levels, transforming the nearest development zone into the existing development level and constantly creating the higher-level nearest development zone. The problem of classroom setting should be located in the "nearest development area" of students' intelligence. The so-called "pick a burden and let the students jump". If the problem lies in the current level of development, students can pick peaches without jumping, which will not stimulate students' thinking and promote their intellectual development. However, if the problem lies outside the nearest development zone, even if the students try harder, they will not be able to pick the "peaches", which will also not stimulate their thinking and promote their intellectual development.
4. babanski's "optimization" theory.
The optimization of teaching process is the core of babanski's educational thought. He pointed out: "The optimization of teaching process is based on the comprehensive consideration of teaching laws, principles, modern teaching forms and methods, the characteristics of teaching system and internal and external conditions, starting from established standards, so that the process can play the most effective (that is, optimal) role." According to babanski, the most important criteria for optimization are effect and time. All teaching activities should make teachers and students spend the least necessary labor time and achieve the best results, that is, to improve the teaching quality without increasing the burden.
5. Bloom has mastered the learning theory.
Grasp the theoretical points of learning:
(1) More than 90% of the students can master more than 90% of the learning objectives, and the difference is only the length of time;

According to the guidance of the leaders and experts attending the meeting, the research group further revised the Implementation Plan for Improving the Effectiveness of Mathematics Classroom Teaching in Primary Schools.
The second stage (20111-July): the main work and achievements in the implementation stage are studied.
1. Determine the experimental class and experimental control class.
20 1 1 Feb. 25th, 2008 In order to make the experimental research go smoothly and ensure that it is convenient to verify and analyze the experimental effect scientifically and objectively, the research group made a scientific analysis of three classes in the sixth grade of Chang 'an Primary School, and compared their math average scores in the spring semester of 20 10 respectively. Finally, it is determined that the class whose average math score is in the middle level is the experimental control class. Class six C is the experimental control class, while Class six A and Class six B are the experimental classes.
