1Advantage of and reflection on IT in mathematics teaching in primary schoolsInformation technology in teaching, has caused profound changes in education. Reasonable design and application of IT teaching, it is possible to bring the entire educational thought, educational content, educational methods, means of education, mode of education, the educational process for positive change, but practice also allows us to see, the lack of modern teaching philosophy, guidance and effective instructional design, classroom applications of information technology, there are many errors, we should clearly see: the application of information technology in the classroom teaching of modern science and technology and social development the requirements of education, education reform and development needs and to carry out IT-assisted teaching is to improve classroom effectiveness, examination-oriented education in one of the important means of transition to a quality education. Furthermore, the rational application of IT to support teaching, enhance students learning interest, developing teaching ability, 2broaden the problem-solving ideas, intellectual development, focused, and Overcoming Difficulties have a positive effect. more to promote the teachers updated thinking on education, concepts of education, improve teaching methods and deepen the reform of classroom teaching. As a contemporary mathematics teachers to become familiar with the theory and operational skills of the multimedia teaching methods, and based on the standards of teaching and learning, rational use of IT-assisted mathematics teaching. Its basic starting point is to promote the students a comprehensive, sustainable and harmonious development, not only to consider the teaching own characteristics, the tone should follow the students to learn the psychological laws of mathematics, stressed that starting from the students prior life experiences, so that the students experienced the learning process of mathematics, the abstraction of the actual progress and development of student values. Furthermore, in the elementary school mathematics classroom from the students reality, a reasonable 3choice of modern teaching media, and make a reasonable combination of traditional teaching media and conventional teaching methods, can greatly enrich the classroom teaching, to promote the understanding of students knowledge , master, and migration, and cultivate students capabilities, improve the quality of students, and greatly improve the teaching efficiency, bringing the advantages of information technology. A. The advantages of IT in mathematics teaching in primary schools IT in mathematics teaching in primary schools has been a considerable practice, and reflect the many advantages can be summed up, there are: The maps, text, sound, and Mao, can multi-angle arouse the students mood, emotion, attention and interest The intuitive, to break through the limitations of visual, multi-angle observation object, and the salient points, to contribute to the understanding of teaching concepts and methods to master. of the static action, can effectively reflect the concept and process of Overcoming Difficulties. more interactive, more involved in student 4learning more active and realistic environment, the students form a cognitive structure. through the reproduction and simulation of the real scenario of the IT students explore, create capacity. The teaching process can be repetitive in favor forgotten breakthrough difficulty and overcome. the targeted, so that the teaching of students at different levels may be. the large, high-capacity, saving space and time, improve the efficiency of the teaching abstract and difficult concepts into concrete and substantial screen map. , ie, the abstract into concrete. the IT in elementary school mathematics classroom, teachers into managers and explain the status of Technical Assistant , collaborators, and help students thinking process is more focused on the mobilization of cognitive strategies to solve practical problems. in order to learn “how to learn, how to think.” Application of IT in the Primary Mathematics Classroom, indeed for the students learning and teachers teaching to provide good conditions, and received good results, which has become the consensus. 52 Reflection of IT in teaching applications Everything has both positive and negative effects of the application of information technology is no exception. We see the advantage of IT used in elementary school mathematics classroom should also see IT in Education and Teaching into errors Therefore, we must timely detection of errors, analysis errors, the errors. 2.1 multimedia teaching can not be ignored students cooperation, cooperative learning is a teaching method, refers to the students in group learning of its members have different abilities to engage in learning activities. With the rapid development of science and technolog
