"The development of information technology has had a great impact on the value, objectives, contents and teaching methods of mathematics education. The design and implementation of mathematics curriculum should rationally use modern information technology according to the actual situation, pay attention to the integration of information technology and curriculum content, and pay attention to practical results. " Mathematics has the characteristics of strong logic and high requirements for abstract thinking. Traditional teaching methods are mainly static, so it is sometimes difficult to show this complicated thinking process on the blackboard in class. The effective application of information technology can transform complex problems into intuitive, vivid and vivid perceptual scenes, which is conducive to fully revealing the formation and development of mathematical concepts, the process and essence of mathematical thinking, showing the formation process of mathematical thinking, adding new ways for students to learn mathematics, greatly reducing the difficulty of students' understanding and teachers' teaching, and making teaching forms more intuitive and diversified.

First, the research background

(A) the new curriculum and the needs of the development of the times

Since the implementation of the new curriculum reform, some teachers have made some attempts in teaching methods and students' learning methods, but in daily teaching, lecturing is still the main way of classroom teaching, and the phenomenon of "full-time irrigation" is still very serious, and there is widespread sorrow of teachers' "ineffective" work and "inefficient" labor. Students also lack the awareness of active learning. In today's network information age, our traditional classroom lacks modern flavor, which makes children unable to "love" our classroom, leading to the lack of students' interest in learning and the inefficiency of classroom teaching. Therefore, how to effectively use information technology to create an "efficient classroom" and improve students' interest in learning is an urgent task in teaching.

(B) information technology is the need for efficient classroom "burden reduction"

At present, in the process of promoting quality education and new curriculum reform, an important problem is that students' academic burden is too heavy, which seriously hinders the healthy development of students' body and mind. Only by liberating students and giving them more opportunities to practice and experience nature and society can they form the necessary qualities for their "survival and development". Therefore, information technology-assisted teaching is an effective way to "reduce the burden".

Second, what is an efficient classroom?

"Efficient classroom" requires that classroom teaching should have clear goals. Teachers should make full use of the effective time in class, complete tasks with high quality through various effective teaching strategies, appropriate teaching methods and appropriate learning activities, and let students study, practice and attend classes in class, thus reducing their academic burden and ensuring their all-round development in time and space. Efficient classroom, teachers teach happily, students learn happily, and teachers and students interact; Teachers give timely guidance, and students not only master knowledge, but also develop intelligence and ability.

Third, information technology to create efficient classroom strategies for primary school mathematics

(A) the effective use of information technology to create situations to stimulate students' interest in learning.

In the teaching of information technology, based on the theoretical basis of constructivism, combined with the new curriculum standards and concepts, aiming at the teaching objectives, creating teaching situations is conducive to optimizing classroom teaching, improving teaching effect and comprehensively improving students' information literacy. In the introduction of new courses, the rational use of computer-aided teaching to create novel and interesting problem situations can make learning happen in situations that are basically consistent with or similar to the actual situation, stimulate students' interest in understanding, activate the classroom atmosphere, mobilize positive emotions, and make students enjoy and love learning. For example, when learning to calculate the area of parallelogram, I played the theme song of Pleasant Goat and Big Big Wolf with multimedia to stimulate students' interest in learning. The students are happy to sing, so the classroom atmosphere is very active and the students are very interested in learning. Use courseware to design the field dispute between Pleasant Goat and Meiyangyang. Pleasant Goat's field is rectangular and Meiyangyang's is parallelogram. In the animation demonstration of their size, the teacher can let the students guess whose field is bigger first. What do you need first? This leads to the knowledge point of calculating the area of parallelogram. In this way, the introduction of new courses can stimulate students' learning motivation, solve some practical problems in life and activate students' thinking. It can be seen that in the information technology environment, intelligent multimedia courseware can vividly display the teaching content through sound and animation, and stimulate students to participate in teaching.
