Modern distance open education uses computer network and multimedia technology to carry out teaching activities in digital signal environment, which determines that its educational process must reflect students' autonomous learning, students' participation, the application of modern means and the utilization of various media resources. The goal of quality education is to make learners develop in an all-round way and their personalities develop in an all-round way. It emphasizes that the purpose of learning is to realize students' meaningful construction of learning content, that is, to realize meaningful learning. China's educational technology experts also put forward a "double-qualified" teaching model with teachers as the leading factor and students as the main body. This teaching mode is the combination and complementary advantages of "teaching-centered" and "learning-centered". Basically, the teaching process of "transmission and reception" has been retained, with reception learning as the main learning method. Teachers are sometimes in the center, but more often, under the guidance of teachers, students learn independently. Pay attention to the cultivation of learners' cognitive ability and creative ability, which can only be cultivated on the basis of mastering the necessary knowledge, mainly in practice. Therefore, practical exercises, free operation, social practice and other learning contents based on students' personal experience should be added in teaching, and interactive teaching tools must be used in classroom teaching to turn chalk and blackboard teaching into practical teaching. To achieve this goal, we must apply modern educational technology with computer as the core.
1. Use distance education as a teaching method.
With the development of society, the change of times and the reform of education, the teaching space is no longer limited to blackboards and platforms. With the help of multimedia tools and platforms, teaching can be carried out from multiple dimensions such as vision, hearing and touch. Not only the teaching, guidance and help of teachers should be carried out through various media, but also the learning and exploration of students should be realized with the help of various media. In addition, various computer networks also constitute a tool for teachers and students to exchange information, and teachers' guidance and students' feedback should be carried out on this basis. Distance education is a school without walls, and its teaching information covers the whole country through the satellite TV system provided by the state, and online teaching is carried out for the whole country by using the computer network. At the same time, modern distance education teaching system can work together at different levels to provide teachers and students with necessary learning resources and learning support services.
2. Modern distance education is an indispensable available resource in modern teaching.
In today's educational reform, learning and cultivating students focus on the all-round development of their abilities, not one-sided development. Quality education attaches importance to knowledge and ability, and no longer emphasizes the memory of knowledge unilaterally. Therefore, in this "learning"-based environmental system, a large number of teaching and learning resources must be selected and applied. Modern educational technology can provide a variety of learning resources, such as audio-visual tapes. Quality education attaches importance to knowledge and ability, and no longer emphasizes the memory of knowledge unilaterally. Therefore, in this "learning"-based environmental system, a large number of teaching and learning resources must be selected and applied. Modern distance open education uses computer network and multimedia technology, and the teaching activities in the digital signal environment determine that its education process must reflect students' autonomous learning, students' participation and the application of modern means.
3. Modern education is inseparable from distance education technology.
Modern educational technology can construct various teaching environments, such as multimedia comprehensive classrooms, multimedia computer network classrooms, electronic reading rooms and campus networks. In classroom teaching, the application of multimedia technology, network technology and virtual reality technology can create and display various realistic learning situations, integrate abstract learning with real life and stimulate students' thinking and exploration. This is not only a reform of educational form, but also an educational concept. It makes full use of social educational resources, modern educational technology and flexible learning support services to provide learning conditions and an all-round good learning environment for all those who have the desire to learn. Education takes educational technology and media as curriculum carriers, so that the process of teaching and learning can be carried out asynchronously or synchronously, because learners' different family economic environments have different driving forces and influences on autonomous learning. A better family economy can have more material conditions to receive and consume education, and the improvement of ability will in turn promote the improvement of living environment and help the continuous improvement of independent learning.
4. Teaching and learning in the new era is realized through distance education.
In teaching, cooperative inquiry is needed. Cooperative learning is a teaching form in which two or more subjects jointly promote each other's learning to improve the learning effect. Cooperative learning can develop students' self-confidence, especially enable students who fail in their studies to experience successful experiences and rebuild their self-esteem in the process of peer help; Cooperative learning can improve students' learning enthusiasm and initiative, develop students' subjective consciousness, eliminate the indifference and isolation between people caused by competition in exam-oriented education, and form a harmonious and equal relationship between teachers and students. It can be seen that cooperative learning is an inevitable requirement of the "learning"-centered teaching model. Cooperative learning can be effectively carried out by applying various network environments provided by modern educational technology.
The above simply analyzes the position and role of modern educational technology in creating a new teaching model. How to establish an effective teaching mode on the basis of applying modern educational technology should be creatively explored and developed by various regions and schools according to their own conditions.
In short, through effective teaching design, we can give full play to the advantages of modern educational technology, establish an effective teaching model, and promote the realization of quality education. Let modern distance education serve teaching better.
