Research and practice on the integration of information technology and elementary school mathematics subject Elementary School Mathematics Lesson Plans

Abstract Combined with the teaching practice, the research and practice of the integration of information technology and elementary school mathematics discipline, to make some preliminary discussions.　Keywords Information technology; elementary school mathematics; multimedia courseware Informationization is the general trend of economic and social development in today's world, and the continuous development of information technology with multimedia and network technology as the core is changing more and more profoundly people's way of production, living, working and learning. The development of information technology enables people's learning and communication to break the boundaries of time and space in the past, and brings new space for the improvement of human ability and functioning. Strengthening the "integration" of information technology and other courses is of great significance to the implementation of quality education and the cultivation of innovative talents. Mathematics teachers must further study how to use computers to help their teaching from the perspective of their own subjects, and integrate computer technology organically into the teaching of elementary school mathematics - as natural and smooth as using the blackboard, chalk, paper and pen, in order to better meet the requirements of the times. Then, how to realize the integration of information technology and elementary school mathematics subject?

1 With the help of information technology, create a situation to stimulate students' interest in learning

Teaching has a method, but there is no fixed method, the precious method, the wonderful in the right way. As primary school students are curious, active, intentional attention to a short period of time, poor persistence and other characteristics, often affecting the classroom learning effect. The use of information technology-assisted teaching courseware is not only used to deliver teaching content, but also change the traditional teaching methods and learning styles, is conducive to regulating the classroom atmosphere, create a learning environment, stimulate students' interest in learning mathematics.

Primary school mathematics teaching, the use of information technology, can set up for the students and suspense, stimulate students to take the initiative to obtain knowledge of the enthusiasm, create a conducive to the development of their intellectual capacity, knowledge and exploration of the psychological environment. For example, in the teaching of "comparison", the courseware first presented a meadow, green grass, the teacher guided: "Children, you have seen the grass? What is the scenery on the grass?" Then, the mother duck and ducklings appeared on the screen, "The mother duck also came with her children." "Did everyone have fun on the grass?" "Happy!" ...... In this way, the beautiful images and students' life experiences blend together, and joyful smiles have already bloomed on their faces. Then turn to the conversation between the mother chicken and the mother duck. The mother duck says to the mother chicken, "I have more ducklings than you do." And the mommy chicken says to the mommy duck, "No, I have more chicks than you have ducklings." How do you know if mommy duck has more children or mommy chicken has more children? This raises the question of comparing more and less. After discussion, the students decide to let the chicks and ducklings line up separately, and then one to one, they compare how many. In this way, the students are interested in learning one-to-one correspondence method to compare the number of two quantities, but also feel the beauty of the inculcation.

2 The integration of information technology and elementary school mathematics teaching content

The new curriculum standards put forward "mathematics should be close to life" "mathematical problems living", in fact, the students are more likely to understand and master them have a certain life In fact, it is easier for students to understand and master their mathematical knowledge which has a certain life basis, and they are more interested in it. However, due to the objective constraints, the teaching contents of the existing teaching materials for primary mathematics are obviously old and lagging behind the development of the times. It is difficult to reflect the most vivid teaching materials and contents of mathematics in the world with obvious characteristics of the times in the textbooks in a timely manner. Therefore, the selection of mathematics learning materials should pay attention to the connection with the actual life of students and pay attention to the effectiveness. Teachers can make use of the rich information resources, the characteristics of strong timeliness, the organic integration of information technology and elementary school mathematics teaching content, make full use of a variety of information resources, the introduction of the era of living water, and the combination of elementary school mathematics teaching content, so that the students' learning content is more colorful and more contemporary, closer to life and modern technology; at the same time, it also allows the teacher to expand the horizon of knowledge, change the traditional subject of teaching content, so that the teaching materials "the" teaching content. Teaching content, so that the material "live" up, so that math learning closer to life.

3 Integration of information technology and elementary school mathematics classroom teaching

With the development of small-class education, the organic integration of information technology and mathematics for the teaching of new forms. Based on this thinking, the author consciously let the students themselves to consult the information or social investigation, the study of mathematics from the classroom to extend outside the classroom, not only to broaden the students' knowledge horizons, enriching the knowledge of the classroom, and cultivate the ability of students to independently explore knowledge, improve the ability of students to collect and process information.

The knowledge objective of the lesson "Rectangle, Square and Flat Quadrilateral" is to recognize rectangle, square and flat quadrilateral and to know their characteristics; the ability objective is to cultivate students' logical thinking ability, spatial imagination, and to cultivate students' ability to innovate and learn independently. In order to transform the teacher's teaching design into an interaction with the students' life activity practice, and do everything possible to stimulate the students' active participation, the author designed interactive game teaching in the practice part - jigsaw puzzle game, the computer gives some triangles, quadrilaterals and other recognizable shapes, and the students can drag the shapes at will to put together the shapes of the beautiful patterns, and then use the multimedia show to show the students how to use the computer. The students can drag and drop the shapes to make beautiful patterns of different shapes, and then use the multimedia to show and exchange their own works.

4 Showing the Best Entry Points and Providing Students with Ideas and Methods for Solving Problems

4.1 Entry at the Point of Connection in Life

In our daily lives, there are many things that have certain patterns, such as all kinds of beautiful colored lights in the festivals and the decorative patterns on the objects, all of them are arranged in a regular way, and these regular things always give people a kind of beautiful enjoyment. How to find more learning resources? Computer network is a best learning tool. The computer network has a large amount of information, it can provide rich materials for students to explore the laws of things from the perspective of mathematics, and students can appreciate many beautiful patterns in life. In teaching, the teacher first uses the computer to show a regular pattern in life, clear images, bright colors, so that students can enjoy the beauty of it. Such a beautiful picture caused by the aesthetic sense of students, stimulating a strong desire to explore, and thus enter the realm of knowledge with interest.

4.2 In the knowledge of the open point of entry

In the teaching, the teacher encourages students to find their own rules, and then guide the students to design the best pattern according to certain rules. Students through independent thinking, the use of computer graphics change convenient features, give full play to their imagination, on the computer to choose their favorite graphics, such as circles, triangles, stars, etc., to create many beautiful and regular patterns. In this way, on the one hand, the patterns created are more beautiful than those painted with colored pencils; on the other hand, it reduces the teaching time and increases the capacity of classroom teaching.

4.3 Cutting in the point of cooperation and communication

After the students create independently, the group appreciates and evaluates each other, and in the process of evaluation, the students can modify their works until they feel satisfied. On this basis, the best works are selected in the group. Teachers can use network technology to call up these students' works for display and exchange them in the whole class, asking other students to appreciate and evaluate them. In this way, they are in the exchange of seminars, not only to learn the results of other people's research, but also their own research results have a sense of joy, sense of achievement, while feeling the joy of communication with others, exploration, in the operation of the activity to experience the process of knowledge formation, learning more actively. This kind of teaching, not only to make information technology and math teaching content organic combination, more conducive to the cultivation of students active exploration, cooperation and communication skills.

5 Reflection on existing problems

1) Teachers are the leading role in teaching, students are the main body of teaching. Multimedia courseware is a means for teachers to teach, and it can be utilized to achieve the purpose of teaching more effectively. But it can only serve as a tool and cannot replace the role of the teacher. Multimedia courseware can be loaded with knowledge, but can not replace the book. Students should be based on the basis of the textbook, the use of multimedia courseware to deepen the understanding and mastery of knowledge.

2) The rapid development of modern information technology, computer-aided instruction courseware plays an extremely important role. But computer interactivity and computer-assisted teaching courseware hypermedia, hypertext expression and student learning cognitive information organization structure relationship, the intelligence of the teaching software, how to promote the formation of students' cognitive structure, so as to further improve the students' ability to learn on their own, is still to be studied in depth.
