With the development of modern educational technology, the role of teaching media, especially audio-visual media, in teaching is becoming more and more obvious and important. Modern educational technology, as an important auxiliary tool of the discipline, plays a self-evident role in solving the difficulties and key points of the discipline for teachers and students. The application of modern educational technology, to a certain extent, promotes the contact between teachers and the outside world, stimulates students' interest in learning, and improves teachers' requirements for their own quality. With the development of curriculum reform, the effectiveness of teaching is more reflected in the integration of modern educational technology and disciplines. This integration refers to the integration of modern educational technology with curriculum structure, curriculum content, curriculum resources and curriculum implementation, which becomes an organic part of the curriculum and implements teaching harmoniously and efficiently. As a teacher, how to use information technology to transfer knowledge and experience better and more effectively. The following is my preliminary understanding of whether modern educational technology can be effectively applied to subject teaching: First, how modern educational technology can become an effective means of classroom teaching. Some people say: "Teachers' life is in the classroom, teachers' soul is in the classroom, and teachers' value is also in the classroom. To become a research-oriented teacher, teachers must return to the classroom and base themselves on the classroom. "Yes, classroom teaching is a common means in education and teaching. It is the whole process of teachers imparting knowledge and skills to students, mainly including teachers' explanations, students' questions and answers, teaching activities and all teaching AIDS used in the teaching process. Classroom is the main position of teachers' teaching. With the development of the times, modern educational technology has become a way for teachers to create situations in the classroom, crossing the limitations of time and space, and making teaching more simple and convenient. Enriched the classroom resources. Broaden students' horizons, set an example and promote the common development of teachers and students. However, if teachers want to give full play to the role of modern educational technology in the classroom, they must seize the opportunity to use modern educational technology at what time and where to serve the teaching. Due to the different nature of subjects, the purpose of classroom teaching may be different, which requires teachers to accurately grasp the opportunity of the application of modern educational technology to ensure its best role in classroom teaching. In my opinion, the application of modern educational technology can be seen from the following aspects: first, teachers can try to use it in order to arouse students' enthusiasm and create an ideal scene for the new curriculum. Students are interested in the knowledge to be introduced and can make the best preparation for future teaching; Secondly, in order to solve the difficulties of this course, we can use this power to solve those that are difficult to solve with our ordinary teaching methods, which are not vivid, intuitive or can not achieve the expected results; Finally, in order to extend the knowledge of the text, we need to make a general summary in a short time and use such necessary means. Second, use to solve the combination of modern educational technology and discipline. Teachers should have an overall understanding of the application of modern educational technology in classroom teaching. The application of modern educational technology lies in precision, not quantity. Multimedia teaching is the most commonly used modern educational technology in our teaching. Rich expressive force, can simulate various situations, and comprehensively use multimedia means such as images, videos and animations to create situations. It can transcend the concepts of time and space, turn static into dynamic, abstract into intuitive, and complex into simple and clear. But it is a tool to solve the teaching service, and its application is often to solve the problems that students are difficult to understand, unfamiliar and lack in conventional teaching. This puts forward higher requirements for teachers, who are the main body of using modern educational technology in the classroom. On the one hand, teachers are required to have high knowledge and skills in this field. On the other hand, teachers should be clear about how to use the skills they have mastered to better serve the content they teach, which is the ultimate goal. Therefore, teachers need to spend a lot of time exploring and thinking about when and under what circumstances information technology can be better displayed. For example, it is unrealistic for junior primary school students to understand the artistic conception of the text simply from the abstract text, especially after a long period of cultural accumulation, even researchers in this field need to ponder carefully, so it is necessary to lower the text requirements and use effective means to achieve the understanding of this kind of knowledge by primary school students. For example, Mr. Ma in the training textbook uses modern educational technology to make the classroom that was originally limited by conditions vivid and intuitive, and improve the efficiency and atmosphere of the classroom. For example, when I used to teach the composition "Looking at Lushan Waterfall", in order to let students better understand ancient poetry, I also. I took great pains. Observing Lushan Waterfall from multiple angles is the starting point for understanding ancient poetry. It is unrealistic for students to observe physical objects, so modern educational technology will become the best teaching means. Although the conditions were not allowed at that time, students could not know the "true face" of Lushan Mountain. In order to teach better, I specially found a photo studio, selected several photos of Lushan Waterfall from different angles with their computers, and used the projector to let the students observe, which made the teaching more effective. Second, how modern educational technology really becomes a tool for students to learn. Future study should be an organic combination of teacher's teaching and student's learning. It should not be the reproduction of teachers' simple teaching resources in class, but the comprehensive utilization of teachers' education and students' resources. It is a more effective transmission of educational information, an extension in the classroom, a supplement after class and classroom, and an effective way to truly reflect students' autonomous learning, inquiry learning and professional learning. At present, the teaching and application of modern educational technology often only stays in the simple demonstration of teachers in the classroom, serving their own teaching. In order to prevent students from influencing their own teaching or other reasons, teachers themselves become the owners and decision makers of modern educational technology, which violates the objective laws of teaching. Our education is human education, which is unpredictable due to human factors. In the classroom, it is always easy to see such a situation: links carefully designed by using media and other conditions are forced to terminate because of students' sudden problems. In most cases, the reason for this situation is that teachers only prepare lessons and ignore the important subject-students. Whether teachers can use their own thinking about the text, use reasonable means to solve problems, and let students follow the trend to participate in the application of information technology, so as to realize the real interaction between teachers and students through effective ways and the advantages of modern educational technology, improve people's living standards, and let more and more people enjoy the information life. Then with the help of modern educational technology, students can use their own knowledge, and only through independent learning and cooperative inquiry can they have real significance. In short, the progress of the times should reflect the teaching of the times. How to make our teaching keep pace with the times and innovate independently requires more modern educational technologies.
