First, the combination of information technology and the subject characteristics of mathematics teaching is conducive to improving students' learning enthusiasm.
Interest is the best teacher. Good interests bring good learning motivation, but not every student has a good interest in learning mathematics. Curiosity is the nature of students. They are interested in new things and things they know but have never seen. To stimulate students' enthusiasm for learning mathematics, we must meet their needs. However, traditional teaching and many current teaching are carried out in strict accordance with the syllabus, and students are closed in boring textbooks and monotonous classrooms, completely isolated from rich resources and reality, which leads to a decline in students' interest in learning mathematics. Integrating multimedia information technology into the teaching classroom and using the characteristics of multimedia information technology to create various situations for students, such as illustrations, synchronized audio and video, dynamic and intuitive images, can mobilize the participation of students' various senses, stimulate their strong desire for learning, and stimulate their learning motivation and interest. This fully illustrates the role of multimedia information technology in teaching.
Secondly, the combination of information technology and the subject characteristics of mathematics teaching is helpful to help students explore and discover.
The process of mathematics teaching is actually a process in which students study and explore solutions to mathematical problems under the guidance of teachers, and then extend and innovate. Therefore, how teachers design and choose math problems has become the key to math teaching activities. The problem arises from this situation. Therefore, creating situations in teaching activities is the core of organizing classroom teaching. The application of modern multimedia information technology such as network information and multimedia teaching software provides us with powerful situational resources. For example, in the teaching of "Basic Concept of Plane Vector" and "Coordinate Representation of Plane Vector", I made a dynamic courseware of Plane Vector with Powerpoint. Through exploration, students discovered the basic concept of plane vector and deeply understood the significance and function of coordinate representation of plane vector. When explaining the related problems of space quadrangle, if students only use the model to observe and make the plan of space quadrangle on the blackboard, then when solving related problems after class, most students will naturally think that the two diagonals of space quadrangle intersect. In teaching, I use the three-dimensional geometric sketchpad to import basic graphics, make quadrilateral graphics of rotating space on site, and add lines on site. In the process of rotation, let students feel the image of the space quadrangle, cultivate students' spatial observation and thinking ability, thus leaving a deep impression that the two diagonals of the space quadrangle do not intersect, and will not make mistakes in solving other related problems. At the same time, students discovered the concept of non-planar straight line in this process, which laid the foundation for the later teaching of non-planar straight line. It can be seen that the role of multimedia information technology in creating situations is incomparable to traditional teaching methods.
Thirdly, combining information technology with the subject characteristics of mathematics teaching will help students acquire skills and experience.
Mathematics is a science that integrates rigor, logicality, accuracy, creativity and imagination. Mathematics teaching requires students to constantly know, understand and master this science through positive thinking in the teaching activities designed by teachers or in the environment provided by teachers, so revealing the thinking process and promoting students' thinking has become a special requirement of mathematics education. Multimedia information technology has great potential in mathematics education. Using multimedia information technology to guide students' learning in teaching can not only help students improve their ability to acquire skills and experience, but also help students improve their thinking and understanding ability, and cultivate their initiative in learning. For example, before I explain the concept of limit, I ask students to use the Internet to inquire and collect information about limit. By sorting out the data, I put forward practical problems related to limit. Through my animation courseware, the students summarized the concept of limit and revealed the connotation of the concept of limit. More importantly, in the process of inquiring and collecting information about limits through the Internet, students deeply appreciate the interactive learning environment of the Internet, which is open, colorful and boundless.
Fourthly, the integration of multimedia information technology into the teaching classroom helps to reduce the teaching workload of teachers.
In the process of preparing lessons, teachers need to consult a lot of relevant materials, and the huge stacks have only limited resources. Moreover, the teacher has to search page by page, turning page by page, which consumes a lot of time for the teacher. Network information provides endless teaching resources for teachers and opens up a shortcut for teachers to carry out teaching activities. As long as you enter the URL in the address bar, you can download the required information in a short time, which greatly saves the time for teachers to prepare lessons. With the rapid development of computer software technology, the establishment of distance education online school has created a huge communication space for educators. The emergence of a large number of practice software and computer-aided testing software enables students to consolidate and master what they have learned in practice and testing, determine their next learning direction, and realize individual tutoring teaching. At this level, computer software has partially replaced the functions of teachers, such as setting questions and evaluating. , thus reducing the burden on teachers. Therefore, the occurrence of teaching has a strong dependence on technology, and the function of multimedia information technology as a teaching aid tool can be reflected.
Fifth, the integration of multimedia information technology into the teaching classroom is helpful to improve teachers' professional level and computer skills.
The establishment of distance education online school has created a huge communication space for educators, and excellent teachers from all over the world gather in this space, providing inexhaustible teaching support for teachers working in the front line of education. Through network communication, we can learn their new and advanced teaching ideas, teaching concepts and teaching methods. Practice has proved that teachers who often use multimedia information technology in classroom teaching are always at the forefront in their teaching ideas, teaching concepts and teaching methods. In addition, the application of multimedia information technology and computer-aided teaching software in the teaching process requires teachers to have considerable computer skills, and the level of computer skills is the standard for the new generation to evaluate personal cultural quality. The rapid development of computer information technology puts forward new requirements for everyone. As a teacher, we should actively promote the development of computer information technology, and use multimedia information technology in the teaching classroom to benefit others and benefit ourselves.
Reflections on the integration of multimedia information technology of intransitive verbs into teaching classroom
The development of the times requires competitors to improve their own quality, and also requires school education to be at the forefront of development. The development direction of school education requires teachers to update their teaching methods, which are mainly dominated by educational concepts. Therefore, we must first change the concept of education and really apply information technology to teaching. With information technology as an auxiliary teaching tool, give full play to the advantages of information technology in students' autonomous learning, active exploration and cooperation and exchange, and realize the transformation of teachers' roles well. The role of information technology in mathematics teaching can not be underestimated, and it is better than any previous technical means in assisting students' cognition. But it is only an auxiliary tool for classroom teaching. The core of the process of teaching activities is the process of emotional interaction between teachers and students, which is irreplaceable in information technology education. In the process of interactive teaching and learning between teachers and students, information technology has become a signpost to produce mathematical problems and promote the diffusion of students' thinking. However, we can't blindly replace the position of teachers in teaching activities with information technology. Therefore, applying multimedia information technology to classroom teaching objectively and reasonably and actively exploring the integration method of multimedia information technology and classroom teaching are the concepts that modern teachers should change in their teaching activities.
At present, information technology is sweeping all fields of primary and secondary education in China with an irresistible trend, changing people's traditional education, teaching concepts, teaching methods and teaching models at a rapid pace. Therefore, as today's educators, only by actively participating in this change, reforming their old teaching concepts and old teaching models, understanding new ideas and mastering new technologies can we quickly acquire and establish cultural values in the information age and skillfully and reasonably apply them to teaching practice. Computer-aided instruction is the core content and technical means of information technology applied to education. With the continuous development of computer education in primary schools in China, it will be the only way to modernize education. It has become a fashion to use computer-aided teaching in Chinese teaching in primary schools, and its exploration and development has become an important part of Chinese teaching reform. Here I will talk about my feelings about the role of information technology in Chinese teaching.
First, intuitive teaching, easy to understand.
In Chinese teaching, it is difficult for students to understand something that is difficult to understand or rarely seen by students. If students watch vivid animations, they can understand them easily. You can turn static into dynamic, abstract into image and virtual into reality. For example, in the teaching of Zhan Tianyou, it is difficult for students to understand the different methods used by Zhan Tianyou to dig Juyongguan and Badaling tunnels only by reading the texts and drawing schematic diagrams. If students watch an example of the excavation process of animation, they will better appreciate the beauty of Zhan Tianyou's method. Watching the train movement with the help of the "herringbone" circuit diagram can help students understand the benefits of this "herringbone" movement, better understand Zhan Tianyou's superhuman wisdom and contact ability, and learn his innovative spirit.
Second, broaden knowledge and activate thinking.
Pupils are naive and lively, curious and playful, but they have strong thinking ability in images. If we only teach Chinese knowledge orally, it will be boring, students will lose interest, and the classroom effect will definitely be unsatisfactory. We must take special measures to solve this problem better. In the teaching of Bird's Paradise, students know that the scenery of the big banyan tree is beautiful by reading the text, but they can't appreciate the static beauty and dynamic beauty there. I played a live video of the big banyan tree in the early morning on TV to let the students see the static beauty of the big banyan tree with their own eyes, and then played the scene of birds flying, and the students once again realized the dynamic beauty. Looking at the shape and sound of a bird, we can imagine the posture of many birds. This static teaching method is intuitive, vivid and clear, easy to control the progress, and the key points can be repeatedly demonstrated, which greatly stimulates students' senses, enables them to concentrate on their studies, fully mobilizes their observation, imagination and creativity, and further enables them to appreciate the beauty of nature. Even if the students don't go to see the big banyan tree in person, they know that there are many natural beauty there, which broadens their knowledge.
Third, create situations to stimulate emotions.
Multimedia-assisted teaching is beneficial to cultivate students' interest in learning. As we all know, the formation of learning interest is the root of learning enthusiasm and the most realistic and active psychological factor. For students, interest is the best teacher and one of the driving forces of learning. For example, when teaching the article "Guilin Landscape", first play the beautiful scenery of Guilin, so that students and the author can row the Lijiang River together and enjoy the scenery of Guilin. Create a scene to visit the Lijiang River, make students interested in such beautiful scenery, and stimulate their feelings of loving the great rivers and mountains of the motherland, so as to learn this text with more interest. Can more deeply understand the quiet, clear and green characteristics of Lijiang River and the strangeness, beauty and danger of Guilin Mountain.
Fourth, improve teaching efficiency and cultivate modern scientific interest.
People often call today's era the information age. The information age is characterized by a large amount of information circulation and a wide range of information. Everyone has to face increasing information, and human beings will accumulate more and more knowledge. Using cloud information technology in teaching will improve teaching efficiency and cultivate students' interest in modern science. When I was teaching the mysteries of life in the universe, I didn't know much about Mars, Mercury and Jupiter. At this time, I showed the students pictures and written materials of these planets with the help of multimedia, so that they can understand what other planets are like with pictures and written introduction, and let them understand why we can't move to other planets to live more quickly. While they understand these truths, they also have a strong interest in science. Students' learning in school determines that their knowledge is limited. Students have a strong sense of information, further understand the development of information technology and its impact on society, and master basic information technology. Students' information technology, self-study ability and innovation ability will also be improved.
Actively explore and study the best combination of computer-aided teaching and subject teaching, and effectively integrate it with subject teaching and reasonably integrate it into your own teaching work. To infiltrate information technology into the teaching process naturally, we should make full use of the advantages and characteristics of computer-aided teaching, pay attention to cultivating students' innovative consciousness and independent learning and exploration ability, cultivate students' ability to analyze and solve problems independently, and cultivate students' ability to obtain information, exchange information and process information, so as to improve the cultivation of students' comprehensive quality and their own success. Looking forward to the educational prospect of 2 1 century, the development of computer education will pave the way for the growth of cross-century talents, actively prepare for the arrival of 2 1 century with fierce competition and informationization, and further deepen the reform of quality education.
