In recent years, our school has made a lot of explorations in the integration of information technology and subject teaching, and achieved some results. Teachers find a combination point in practice, boldly carry out practical activities, and truly use information technology as a cognitive tool for students to promote subject knowledge learning and ability improvement. We mainly adopt the following four forms of integration in practice.
1. Use the existing tools in the computer for comprehensive teaching.
Conventional computer-aided teaching often needs to make a courseware for a class, which is not flexible enough to use and requires a lot of preparatory work before teaching. In fact, the computer itself has a powerful teaching function. We tried to use these functions in teaching practice from 1999, and achieved good results. For example, in the lower grades, intelligent ABC is used for typing, in the middle grades, Excel is used for analyzing mathematical data, in the chart tools, statistical charts are learned, in the upper grades, mathematics is checked with a calculator, and geometric knowledge is learned with a drawing tool. All these fully tap the existing tools in the computer for subject teaching. This not only achieves the purpose of learning and applying technology, but also promotes the study of subject knowledge and effectively stimulates students' interest in learning. The teaching of mathematical problems in environmental protection is one of the typical cases. In the past, this part of teaching often focused on the understanding and drawing of statistical charts. As a result, the teacher taught very hard, and students spent a lot of time drawing and tabulating, but seldom studied the significance of statistical charts and how to use these charts to obtain effective information. The latter is the main goal of statistical knowledge teaching. Using the charting tools in the computer, as long as the corresponding data is input, the computer can automatically generate statistical charts in a few seconds, and can generate different forms of statistical charts as needed. In this way, more time can be spent on the analysis and inference of data change trend, and students' analytical application ability can be cultivated. Practice shows that through integrated teaching, students can not only learn to read statistical charts, but also make appropriate analysis and speculation according to the changes of data, and put forward their own suggestions. It has also achieved the information technology teaching goal of learning to make statistical charts with chart tools; It also cultivated a good awareness of environmental protection and stimulated the interest in using computers. In just 40 minutes, I completed the learning task that can only be completed in at least two classes, which greatly improved the teaching efficiency.
2. Use computer information processing ability to carry out integrated teaching.
Computers have strong information processing capabilities. Using this function, students can reorganize, process and reuse information, and quickly extract useful information from a large amount of information, thus cultivating information processing ability and fluent expression ability, and internalizing a lot of knowledge. For example, lower grades can use computers to draw pictures and match words to express their ideas; Middle-grade students search and download materials on the internet, and make learning report materials with Word; Senior students can collect information, process information and make websites through various forms. Fifty years' teaching of food, clothing, housing and transportation has made full use of the function of computer information processing. Before class, the teacher made a homepage, which specifically introduced the great changes in New China in the past 50 years. There were many materials, pictures and data in it. Students can freely choose topics of interest and corresponding materials to study, and finally complete the research report in the form of group cooperation. In this lesson, students collect relevant materials in the virtual network, including words, pictures, animations and so on. Then, according to the learning objectives, the information is filtered, and the selected information is analyzed and processed, then combined and recreated, and finally the learning result is obtained. Some students also make their learning results into web pages. Here, on the one hand, the computer plays the role of "information tool" in students' learning process, promoting students' information literacy, on the other hand, it appears as a "publishing tool" to help students sort out their knowledge, and comprehensively use the knowledge of Chinese writing, art painting, awards and so on to complete research reports, so that knowledge can be internalized and activated.
3. Integrated teaching of computer simulation experiment.
With the rapid development of information technology, the application of new technology in teaching provides strong support for students' exploration and learning. Many experiments that are difficult to do in reality can be simulated by computer, thus giving students a real feeling and promoting students to master knowledge and develop their abilities. A typical case is the lesson "The size of possibility". Probability, the mathematical knowledge involved in this course, is extremely abstract. In order to make students better understand this knowledge and really improve their application ability, we adopt two strategies in teaching: one is to create specific situations for students to change their roles and choose promotion schemes as the "boss" of shopping malls; The second is to use the computer to conduct a large number of repeated simulation experiments to experience the meaning of "probability" and help make correct decisions. Because computers can help get thousands of simulation results, and can also analyze and count data quickly and accurately, students can not only reduce a lot of repeated experiments and tedious calculations, but also improve their learning efficiency and understand the significance of mastering probability more easily after integrating computer technology into "probability cognition". Experiencing a lot of repeated experiments will make the results more accurate and help them make reasonable decisions. More importantly, through integration, students really realize the importance of information technology application and the urgency of learning style revolution.
4. Use websites for research study and collaborative study.
Research-based learning means that students choose and determine research topics from their own life and social life under the guidance of teachers, and actively acquire knowledge, apply knowledge and solve problems in a way similar to scientific research. The process of inquiry learning is a process of interpersonal communication and cooperation. Its purpose is to better cultivate students' information collection and processing ability, cultivate innovative spirit, gain positive experience of participating in research and exploration in person, and improve communication and cooperation ability. Computer network technology provides a good technical foundation and supporting environment for better research-based learning and cooperative learning. Such as: providing rich research resources, creating vivid research situations, greatly expanding the scope of cooperation, improving cooperation efficiency, and reforming learning methods. "Beijing Olympic Games-Our Expectation" is a typical case of using the network to carry out research-based learning and improve cooperation ability. This course takes students as the research subject and group activities as the leading mode. Students first collect information about the Olympic Games and the Olympic bid through online browsing, book consultation, investigation and interview, and then determine the common research topics of the group through group discussion. Then team members further collect, analyze and sort out relevant information through multiple channels according to the theme, put forward ideas and suggestions, and then use information technology to make the above content into a website with great personality; Finally, all the groups in the class show their achievements, report their gains and exchange their experiences. The whole activity lasted for two weeks, and the students showed great enthusiasm for research and overcame countless difficulties. Each team has made a unique homepage for bidding for the Olympic Games, with a wide range of contents. This activity successfully completed the scheduled task, which had a good influence on students' development in many aspects: in the cognitive field, it broadened the scope of knowledge and improved the ability to solve practical problems comprehensively, including browsing and searching with IE information, sending and receiving emails, editing and typesetting with Word, making FrontPage web pages, making COOL3D animation and Photoshop image processing, organizing language and characters, data processing, beautifying layout design and other technologies; In the field of interpersonal communication, learn to respect, listen, persuade, communicate and communicate; In the field of emotional attitude, they have enhanced their friendship, exercised their perseverance in overcoming difficulties and improved their self-confidence in learning. It can be said that this is a big review of students' existing knowledge and ability.
In these typical lessons, information technology is organically integrated into the whole teaching process in the form of tools, and it is difficult for us to separate it from the teaching process because it directly serves the teaching objectives. Moreover, in the whole teaching process, students' subjectivity and personality have been greatly reflected, and such a teaching atmosphere is very conducive to the cultivation of students' innovative spirit and problem-solving ability. Similarly, teachers play a leading role by integrating tasks. They help students study in various forms and means, which further mobilizes their learning enthusiasm.
