In recent years, modern information technology based on multimedia network technology has made continuous progress, thus profoundly affecting the life and work of modern people. Traditionally, the memory of knowledge is the main theme of teaching qualified talents in the era of knowledge economy. Using modern educational technology to train contemporary builders is a new requirement for educational institutions. The application of modern technology education in school education is more and more extensive, thus effectively changing the indoctrination teaching strategy. Modern educational technology is characterized by intuition, large amount of information, high teaching efficiency and the teaching effect achieved by conventional education and teaching methods. Using modern educational technology to assist classroom teaching has been more and more accepted by teachers, which makes it more and more realistic to optimize teaching effect. It is worth noting that the application of modern teaching technology has not produced good teaching results. In terms of the shortcomings of using modern educational technology in teaching, teachers have shortcomings in understanding and practice. If it is not handled properly, it will have a bad influence on the improvement of teaching quality. On the basis of the positive influence of modern educational technology on teaching, this paper also discusses its shortcomings.

First, the importance of modern educational technology in teaching

As far as we know, there are many factors that affect the improvement of education and teaching quality. Besides the talent training plan, strong teachers and suitable teaching materials, there are many factors that improve the experimental training facilities owned by this school. The progress of education in China has obvious regional characteristics, and the progress of schools in different regions and at different levels has been unbalanced. Therefore, in the adjustment period of educational progress, we should actively introduce modern educational technology, an advanced teaching method, to better innovate the old traditional teaching strategies of the school, to make up for the limited original resources, to use advanced multimedia technology and network technology to solve the contradiction between hardware facilities and the improvement of teaching quality, and it is a feasible idea to apply modern educational technology to teaching.

With the continuous progress of modern information technology, the application of information technology in education has made society very inadequate and innovated traditional education. Educational technology is the discussion and practice about the design, development, management and evaluation of learning and learning resources, while modern educational technology is based on educational discussion and learning discussion, which is a breakthrough of information technology based on computer application technology in modern teaching field and teaching innovation. Its important quantities are: first, it has a greater relationship with the discussion content and modern science and technology; The second is to use the latest scientific and technological achievements to spread all kinds of educational information, so as to educate more colorful materials; Thirdly, it absorbs the scientific and systematic way of thinking, making modern educational technology more distinctive and systematic.

Second, the positive role of modern educational technology in teaching

(A) to promote the diversification of teaching content and form.

With the introduction of modern educational technology, teaching content and embodiment become more and more important. In teaching practice, we can not only use images, words and dynamics to express the corresponding content, but also use sound simulation to teach, which improves the teaching quality and efficiency. It can also provide students with various forms of sensibility with different functions, thus promoting students' multi-sensory learning, better mobilizing brain activities and increasing the intensity of perception, understanding and memory.

(B) Differentiated teaching

Individualized differences among students of modern educational technology, writing learning programs for each student to choose, indicating that teaching adapts to the individual thinking characteristics of each learner, so that each student can analyze and judge his own personal situation and make evaluation and guidance accordingly. Therefore, under the friendly man-machine interface, the interactivity of information technology-assisted teaching system enables students to learn more actively, thus giving full play to the positive role of learners and facilitating educators to teach students in accordance with their aptitude.
