First of all, the role of teachers has been changed, and teachers have become the guides of students' learning.
Traditional teaching emphasizes the leading role of teachers, and their roles as teachers, preachers and puzzles are paternalistic. Compared with students, teachers are owners and disseminators of knowledge and symbols of authority. Teachers are the center, ignoring the learning role of students, making students become passive recipients of knowledge. After modern educational technology enters classroom teaching, the role of teachers has changed from its characteristics and characteristics. Teachers are no longer the only source of information for students to acquire knowledge, and students' authority consciousness is gradually lost. The role of teachers has changed from simply imparting knowledge to teaching designers, guiding students' activities and guiding students to acquire knowledge. Under a certain social and cultural background, under the guidance of teachers, students use necessary learning resources to acquire knowledge, learn to learn and actively explore knowledge by means of meaning construction. Of course, the role of teachers in imparting knowledge, organizing and managing the teaching process and setting an example has been better played. At the same time, as the instructor of students' learning, teachers should strengthen the guidance of students' learning methods, so that students can gradually change from passive knowledge recipients to active knowledge explorers and enterprising people. Teachers should design and make teaching software (courseware) for students to learn according to the curriculum plan and students' needs. In addition, teachers must learn modern educational technology.
The second is to change the status of students and enhance their subjectivity.
In traditional teaching, students rely on teachers' organization, arrangement and requirements to learn. Students passively listen to the teacher's knowledge and are always in a passive position of being instilled. Only by relying on the teacher's explanation can students master knowledge, and only by relying on the teacher's evaluation can they know their progress. Modern educational technology has changed students' dependence on teachers after entering classroom teaching. Modern teaching media, such as audio tapes, video tapes, computer software, CD-ROM, multimedia technology (such as virtual reality and hypermedia technology) and the Internet, with their unique advantages, provide students with diversified external stimuli and rich learning resources, as well as various opportunities for students to participate, give full play to their main role, and provide students with opportunities to actively participate, discover and explore knowledge. The time, content and progress of learning can be mastered by oneself, which makes students change from passive learning to autonomous learning, improves students' attention and interest in learning, cultivates students' various abilities and improves learning effect. Of course, students' self-learning and self-education must be carried out under the guidance of teachers. Modern educational technology has entered classroom teaching, and the teaching system has changed from the traditional "one person" system to "one person, one machine" or "one person, one machine". This system is a mutually beneficial teaching relationship of two-way participation, two-way communication, equality and mutual assistance, but the influence of teachers on students' personality spirit is reduced, which is not conducive to the development of students' personality, emotion and cooperation. Therefore, in the practice of education and teaching, we must strengthen mental health education and humanistic quality education.
Thirdly, the role of teaching media has changed and become a cognitive tool for students.
In traditional teaching, teaching media is a tool for teachers to complete teaching tasks and impart knowledge. After modern educational technology enters classroom teaching, information technology, communication technology and network technology with computer as the core provide new means for classroom teaching, inject new vitality and change the traditional teaching methods and modes. Modern teaching media, such as multimedia courseware, electronic operating system, virtual reality, electronic publications, hypermedia technology, distance learning and online school, can help students to fully perceive and understand knowledge without being limited by time, space and movement state by directly intervening in the teaching process with colorful means of expression. At the same time, students can make use of the high interactivity of modern educational technology to study independently and choose the guidance of teachers and experts. Any kind of teaching media has its advantages and limitations, and has its own value in different situations. In teaching, various media should complement each other.
Fourth, change the structure of teaching content and attach importance to cultivating students' learning methods and learning ability.
The renewal and development of teaching content always follow the progress of society and the development of science and technology. At present, computer network technology and multimedia technology are developing rapidly, changing people's learning methods, working methods and lifestyles at an alarming rate. Information technology has become the fourth tool subject necessary for modern people (the top three are Chinese, mathematics and foreign languages). It is a tool course to cultivate students' ability to acquire and process information, ensure students' active learning and promote their lifelong development. Reading, writing and arithmetic have always been an important teaching content of basic education, and modern information technology has undergone qualitative changes in these fields. Reading has changed from linear text to multimedia e-book, from abstract text to illustrated reading form. Writing moves from stroke-by-stroke practice to keyboard input, mouse input, scanning input, language input and so on. High-speed computing is the most primitive function of computer, and mastering computer technology will replace computing skills and methods. Therefore, the introduction of modern educational technology into classroom teaching will bring about changes in teaching content. It is necessary to enrich and update the teaching content with new knowledge of modern science and technology, and pay attention to cultivating students' basic ability of applying computers and communication, their ability of searching, analyzing and screening information, their ability of collaborative work under the network environment and their ability of solving semi-structured problems. Not only will you teach textbook knowledge, but also pay attention to the cultivation of ability and sentiment, especially the cultivation of learning methods and learning ability. In a word, the application of modern educational technology in classroom teaching can not be simply regarded as a problem of the application of teaching means or teaching methods, but a profound change in the field of education, which will lead to the change of teaching content, teaching means, teaching methods and teaching mode, and finally lead to the fundamental change of educational thought, educational concept, teaching theory and education system.
As Minister Chen Zhili emphasized in the article "The Urgent Task of Governing High School-Modern Educational Technology", "We should deeply understand the important position of modern educational technology in education and teaching, the necessity and urgency of its application, and fully understand that the application of modern educational technology is the requirement of modern science and technology and social development for education, as well as the need of educational reform and development", and call on "teachers of all levels and schools to keep up with the pace of scientific and technological development and strive to master and apply modern educational technology in order to improve their own quality and adapt to it.
