Research report on how to improve the efficiency of mathematics classroom teaching in primary schools

Mathematics Curriculum Standard (Experimental Draft) points out that students are the masters of learning and teachers are the organizers, guides and collaborators of learning. The new curriculum concept advocates the concept of "student-oriented", which is to let students actively explore new knowledge and experience the fun of learning in a democratic, harmonious and pleasant classroom atmosphere, so as to realize "everyone learns valuable mathematics; Everyone can get the necessary mathematics; Different people have different developments in mathematics. " Practice has proved that the teaching concept directly affects the efficiency of classroom teaching. If the teaching concept is not solved, no matter how good the teaching materials and perfect the teaching methods are, they will be "out of shape" when used. In order to improve the efficiency of primary school mathematics classroom teaching, we must change the traditional teaching concept, establish a brand-new system that conforms to the modern teaching concept, and strive to realize the "six transformations"?

(1) The change of the central position One of the main drawbacks of traditional mathematics teaching is that it ignores the subjective initiative of students, who are the main body of the learning process. Teachers are self-centered and become "sellers" of knowledge, and students are regarded as "containers" that can be painted with various colors or put into various things at will. ?

The educational concept of the new era requires that students should be highlighted as the main body, and students should be regarded as "people" with feelings and needs, rather than "containers" of knowledge or "machines" of examinations, and a relaxed, happy and harmonious learning atmosphere should be actively created. ?

(2) Role Positioning In addition to his official functions of "preaching, teaching and dispelling doubts", a teacher is increasingly becoming a consultant, a person who helps to find contradictory arguments instead of taking ready-made truth. He must concentrate more time and energy on those effective and creative activities. The new curriculum emphasizes that teachers are partners, guides and participants in students' learning, and teachers should pay attention to transforming students' thinking and spirit in practice. ?

Teachers' role as knowledge givers has not been eliminated, but unlike before, it is no longer the only role of teachers. Therefore, teachers in the new era must re-locate and recognize their roles, from simple knowledge imparting to students' friends and admirers, students' learning promoters, curriculum developers and builders, and education and teaching researchers. ?

(3) Changing the learning style Learning style is what people have or prefer when studying.

Mode is the sum of learning strategies and learning tendencies with individual characteristics that learners have always shown. The new curriculum requires changing the original single passive learning method, establishing and forming diversified learning methods to mobilize and give play to students' subjectivity, promoting students' autonomous learning under the guidance of teachers, cultivating students' innovative spirit and practical ability, and advocating "autonomy, cooperation and inquiry" learning methods. ?

Ward said, "mediocre teachers pass on knowledge, ordinary teachers explain knowledge, good teachers show knowledge, and great teachers inspire students to learn knowledge." Students are the main body of learning, and learning is a participatory activity. The way students learn is to practice-keep practicing until learning becomes their second nature. ?

(4) Optimize teaching methods Traditional teaching uses chalk and blackboard. Someone joked that "a piece of chalk travels all over the world". This monotonous teaching method restricts the improvement of mathematics teaching quality and the development of students. Therefore, to improve the efficiency of classroom teaching, we should pay attention to the optimization of teaching methods. Reasonable use of multimedia-assisted teaching, combined with sound and animation, can improve students' interest in learning and stimulate their thirst for knowledge. Can let them actively participate in learning. This is of great significance to give full play to students' imagination and creativity, turn "static" content into "dynamic" image, develop students' intelligence, cultivate students' ability to observe, think and solve problems, and realize the optimization of classroom teaching. "Geometry" is the key and difficult point in primary school mathematics learning. Solving problems requires students to have a certain spatial imagination. Because of age, students' thinking development is in the transition stage from concrete image to abstract, so it is not enough to solve relatively complex graphics. If we use multimedia teaching to make static geometric figures move, the problem will become simple. For example, when calculating the area of combined graphics in teaching, we can use computer demonstration to solve the difficulties by translating, adding straight lines, rotating and reorganizing overlapping graphics, so as to find the breakthrough point of solving problems, let students see the process of specific images, understand the composition of graphics, and find the method of solving problems.

(V) Optimizing teaching objectives Teaching objectives determine the direction of teaching activities, the choice of teaching contents, methods and means, and the improvement of teaching efficiency. The traditional teaching goal is "one size fits all", ignoring the individual differences of students. It is unrealistic and utopian to tailor different teaching goals for each student, but it is feasible to set hierarchical goals. It can be divided into lower limit goal, upper limit goal and development goal. For example, when the teaching algorithms are diversified, I require students with weak ability to master only the basic algorithms, while students with good ability are required to use multiple algorithms. Students with better ability learn to choose the best or come up with a better method on the basis of using a variety of algorithms. In this way, we can design differentiated teaching objectives from students' cognitive differences, and finally "promote all students to get their due development at the original level." ? (VI) Optimizing the classroom structure Modern teaching theory holds that the classroom structure of "teaching" should be changed into the classroom structure of "learning" and the classroom should be turned into a school. According to the newspaper, many teachers in primary and secondary schools in the United States only talk about 10 minutes in each class, and the rest of the time let students communicate with each other, ask questions and digest, and the teachers guide, dispel doubts and solve doubts. Coincidentally, many schools in China require teachers to speak only 15 minutes in a class, and let students "choose freely" in the rest of the time, and the teaching effect is also very good. Different class types have their own basic structural models, and the same class type
