At present, the integration of information technology and subject teaching has become the focus of basic education teaching reform. Only by accurately grasping the concept, principles and methods of the integration of information technology and subject teaching can we realize the fundamental change of teaching methods and learning methods and improve the teaching effect through the application of modern information technology in subject teaching. I. The meaning of the integration of information technology and subject teaching The integration of information technology and subject teaching refers to the organic combination of information technology, information resources and subject teaching. Through the effective application of information technology in the teaching of various subjects, it can promote the changes of teaching content presentation, students' learning methods, teachers' teaching methods and teacher-student interaction, create a vivid information-based learning environment for students, make information technology a tool for students to know, explore and solve problems, and cultivate students' information literacy and ability to explore and solve problems independently by using information technology. Second, the principle of integration of information technology and subject teaching In teaching practice, the integration of information technology and subject teaching in primary and secondary schools should follow the following principles: 1. The integration of information technology and subject teaching is to cultivate students' good information literacy, innovative spirit and practical ability under the guidance of advanced educational concepts and teaching theories. Therefore, the integration of information technology and curriculum is not only the application of modern information technology, but also a profound revolution in the field of education and teaching. The integration of information technology and subject teaching should be guided by constructivism learning theory, which can provide strong support for teaching in the information technology environment. 2. Building a new teaching structure The main goal of the current teaching reform is to create a new teaching structure, that is, a student-centered and teacher-led teaching structure. The integration of information technology and subject teaching should give full play to students' initiative, enthusiasm and creativity in the learning process. Students are not only builders of knowledge, but also users of information technology. As the organizer, instructor and helper of learning, the main task of teachers is to construct a suitable learning situation for learners and provide necessary help information. 3. Building high-quality teaching resources is a necessary prerequisite for curriculum integration. The construction of teaching resources can combine the development of teachers with the creation of students, make full use of global and shareable information resources as materials and integrate them into subject teaching. We can collect, arrange and make full use of existing resources through China. Teachers can also develop appropriate teaching resources by themselves. 4. Construct a new teaching mode according to the characteristics of each subject. In the teaching mode based on curriculum integration, information technology should serve the learning tasks of specific subjects. Teachers should combine the characteristics of their respective disciplines to build a teaching model that can not only integrate information technology with curriculum, but also better embody new teaching concepts. Third, the application of information technology in subject teaching From the perspective of the role of information technology in education, the application of information technology in subject teaching mainly includes 1. As a demonstration tool, information technology is the initial embodiment of the application of information technology in subject teaching and the lowest level of the integration of information technology and curriculum. Teachers can use ready-made computer-aided teaching software or multimedia material library, use some multimedia production tools to comprehensively utilize various teaching materials, and use simulation software to demonstrate some experimental phenomena. In this way, through reasonable design and selection, computers have replaced traditional media such as slides, projections, chalk and blackboards. And realized the educational function that they could not achieve. 2. Information technology as a communication tool Information technology as a communication tool refers to the introduction of information technology into teaching in the way of assisting teaching communication, which mainly realizes the role of emotional and information exchange between teachers and students. Teachers can set up some special topics or chat rooms according to teaching needs and students' interests, giving students the right to set up special topics and chat rooms freely, so that they have the opportunity to communicate fully after class. In addition, teachers and students can communicate with the outside world and gain knowledge through these communication tools. 3. Information technology as an individual tutoring tool Teachers use practice-based software and computer-aided testing software according to different learning contents and learning objectives, so that students can consolidate and master knowledge in practice and testing, decide the next learning direction, and realize individual tutoring teaching. In addition, teaching can also pay attention to students' individual differences to a certain extent and improve students' learning enthusiasm. 4. Information technology provides a resource environment. With the completion of the China on campus and the Internet China, students' learning resources have changed from monotonous text textbooks to information-intensive, diverse and massive open resource libraries. Learning in this rich resource environment can greatly expand the amount of teaching knowledge, so that students are no longer limited to learning the contents of textbooks, but can broaden their thinking and get in touch with rich information. 5. Information technology, as an evaluation tool, can become a personalized counseling tool for learners to guide personalized learning to a certain extent. Its evaluation system can provide learners with feedback information of learning effect in time, so that students can clearly understand their own strengths and weaknesses in learning, and it is convenient to adjust their learning purposefully. 6. Information technology as an information processing tool Information technology as an information processing tool mainly cultivates students' ability to analyze and process information, emphasizing students' reorganization, processing and re-application of information in the process of quickly extracting a large amount of information. 7. Information technology as a collaborative tool Computer China network technology provides a good technical foundation and supporting environment for the integration of information technology and curriculum and the realization of collaborative learning. The network environment in China has greatly expanded the scope of cooperation and reduced the unnecessary energy expenditure for cooperation. In the process of learning, learners not only learn knowledge and skills, but also gain benefits from processes and methods and experience emotions, attitudes and values through division of labor and cooperation. 8. As an inquiry tool, modern information technology is providing more and more powerful support for inquiry learning, an advanced cognitive activity. According to the needs of teaching, creating certain situations for learners to explore and discover in these situations is conducive to strengthening learners' understanding of learning content and improving their learning ability. Four, the basic mode of the integration of information technology and subject teaching According to the specific teaching objectives and teaching content, the integration of information technology and subject teaching can flexibly adopt a variety of teaching modes 1. The teaching procedure of inquiry (collaborative learning) is: asking questions-grouping research-determining topics-autonomous learning-publishing learning results-information feedback. This kind of teaching highlights students' dominant position, and gradually establishes diversified learning modes including research-based learning and autonomous learning. 2. Explain the demonstration mode to imitate the teacher's classroom teaching and demonstration teaching methods. Make full use of the image, animation, language and music functions of multimedia computers, give full play to the unique interactivity of computers, and present the contents of teaching materials to students. This model can also be used as a form of individualized teaching for students. By choosing the length of study time, it plays the role of teaching students in accordance with their aptitude. 3. Operation and Practice Operation and practice is the most widely used basic teaching mode in the integration of information technology and subject teaching. It enables students to consolidate and master certain knowledge and skills through repeated practice, and improves the speed and accuracy of students' learning tasks. The characteristic of this mode is that the instant feedback function of the computer has been properly applied. 4. Individual guidance Individual guidance mode mainly simulates the teaching situation of teachers to students, that is, using computers to play the role of lecture teachers. It basically adopts the branch program teaching method, which divides the teaching content into a series of teaching units, and each presentation is just a concept or knowledge point. Dialogue "Dialogue" refers to the dialogue between the computer and the students. Computers can ask questions to students, allow students to answer in natural language, and students can also ask questions to computers. This mode realizes the "real" dialogue between computers and students. 6. Teaching Games Teaching games are often used to create a more competitive learning environment. Their content and environment are related to teaching objectives, and they are informative, interesting and educational, thus stimulating students' interest and playing the role of "entertaining". 7. Simulation, also known as simulation, refers to the use of computers to imitate real phenomena or realize theoretical "ideal models". This model is intuitive and vivid, which is very beneficial to cultivate students' ability to solve problems. 8. Computer-aided testing After computers are used in teaching, many schools use computers for teaching evaluation and testing. The questions are displayed by the computer, and the candidates answer questions at the terminal. The computer immediately checks the answers and scores. This kind of test can provide feedback information for candidates in time, and also help students to clarify wrong concepts in time. It is especially suitable for unit tests and is helpful for students to learn. 9. Problem solving Problem solving attempts to provide students with one or several problem scenarios for them to solve. This kind of scene often challenges students with its mystery and confusion, thus triggering students' learning motivation. 10. Discovery learning is a learning method in cognitive constructivism theory. Students are placed in a structured environment through computers, and tools such as exploration, analysis, deduction and calculation are provided, so that students can discover and master new concepts and principles in the process of exploration. 1 1. Remote tutoring and online discussion. Remote tutoring and online discussion mode mainly refers to a learning mode in which learners and teachers use China communication technology in different places on the Internet. Through China. com, we can have classes together, discuss problems together, and do things that were difficult to accomplish in previous teaching methods.
