Description
Distance Teaching, called e-teaching, is a formal teaching and learning system, which is based on electronic communication means To perform a long-distance teaching and specifically designed. Remote teaching is not very expensive and is not bound by geographic factors. It provides a chance to teach for traditional education difficulties. Because distance education is more elastic and can be transferred to anywhere, it can provide learning opportunities for students such as employees who do not accept traditional education due to trute or distance issues.
Teaching Form
There are a variety of different forms, correspondence teaching, television teaching, and broadcast teaching are the categories of distance teaching. These teaching methods have a lot of advantages, such as full Using education resources to make more people are educated; but he also has a big limitations in teaching, especially lack of teaching interactions, this decentralized weakness makes distance teaching are limited by specific professionalism and occasions. Now we are talking about here is a new distance learning distance learning mode utilizes communications, networking, multimedia, computer equipment and technology to overcome the limitations of traditional distance learning and formation. Modern remote teaching requires a complete teaching system support, the system has three links or control environments, the aquary room is a teacher's teaching environment for collecting teaching information; the remote classroom is a student study environment, receive teaching information, feedback, student information; Information is controlled to computer networks.
History
The United States is the world's earliest way to conduct distance education. As early as 1995, there were universities to use network multimedia to carry out distance education, so the current distance education software is more advanced, interactive Strong. At present, domestic exploration of distance education is gradually beginning to develop synchronous teaching systems while paying attention to teaching content. Many companies and organizations in this regard at the forefront of the industry, especially educational institutions such as Beida Jade Bird, in a great national renown recognition; more advanced remote education solution providers such as Beijing Science and Technology Net fixed satellite in the field of teaching It has more than 90% market share.
Although domestic remote education starts a little later than foreign countries, I believe that the efforts through the Chinese people can quickly catch up and exceed foreign companies.
In traditional distance education, teachers and students, students, and students have always been a bottleneck that restricts its development. The popularization of the Internet has greatly improved people's communication efficiency, which has brought a new opportunity for distance education. During the Internet, the world is based on the world, the world's largest computer network Internet is based. Teachers pass the teaching information to the students through the network, students receive information through the network, in the process of learning, Various forms of communication can also be carried out through computer networks with teachers and students.
Teaching Mode
teach teaching
on the Internet to realize imparting teaching can be divided into two forms: synchronous and asynchronous teaching taught. Synchronous teaching refers to a means of teaching the use of real-time interactive distance learning systems, real-time interactive distance learning systems using computer networks, multimedia and virtual reality technology, analogue of classroom teaching on the Internet, so that teachers and students in remote by real-time audio and video, two-way information transfer teaching learning. This model requires high network transmission rates, and hardware devices have certain requirements (camera, microphone, etc.), therefore, greater investment in teaching and learning on both sides, not suitable for the individual-oriented distance learning. Asynchronous teaching refers to the use of the Internet's WWW service for teaching. Teachers have prepared the curriculum in advance into an HTML file, stored on the web server, and students access the information of these courses through the Internet, and through e Mail, BBS and other means, with teachers and teachers Students are exchanged to complete the learning tasks. In this way the investment is small, especially for the party to learn, as long as the conditions have access to the Internet, will be able to participate in the study. Therefore, this is a remote teaching mode that is suitable for individuals.
Exploration Teaching
Exploration Teaching and Teaching Teaching is quite different, there is no pre-prepared course content, but the teacher determines an exploration goal, asking for students to answer, Provide a large amount of information-related information resources for students to refer to the problem, here, the Internet is a best global information base. Another important point is that teachers should be responsible for providing help and guidance on problems in student learning. Help for students is not directly telling him the answer, but gives the appropriate inspiration or prompt, such as a list of URLs related to the issue. This learning strategy completely changes the status of passive acceptance in traditional teaching processes, but allows students to actively active status, and thus effectively stimulate students' interest and creativity. To achieve this strategy, you don't need complex technologies and expensive devices, just discuss your group using email or BS, but you need to have good organization and help guidance.
Collaborative Teaching
Collaborative Teaching refers to the use of computer network by two or more students interact with each other and cooperate for the same learning content, in order to achieve a deeper understanding of the course content and Master the process. In the collaborative learning process based on the I nternet network, basic collaborative strategy, there are four: Competitive, Cooperative, partners and role-playing.
Competition: means two or more students for the same learning content or learning scenario, competing through the Internet, see who can first meet the requirements of the teaching goals. Due to the competitive relationship of the learner, learners will naturally have naturally generated people and born winning. So the learners will concentrate on the process of learning, so that the learning effect is significant.
Collaborative: refers to multiple students to complete a common task of learning, in the process of completing the task together, play to their cognitive characteristics of learners, arguing with each other, help each other, mutual prompt or the division of labor cooperate. The learner has gradually formed
role play in this process of tight communication and coordination in this kind of peer: everyone has such experiences, give someone to someone After a detailed explanation, you will often have new experiences and understandings for this issue. In other words, in the process of learning to help others, but also to help their own learning. Collaborative role-playing strategy is to let different students are playing the role of learners and mentors, learners responsible for answering questions, the learner and the instructor check whether there is an error in the problem solving process. When learners encounter difficulties in the problem solving process, mentors help learners to solve problems.
advantage of distance education
distance learning teaching methods to promote lively, making learning fun. Online teaching a variety of information through the media animation, graphics, video, sound, etc.
The amount of distance education is large, which can greatly improve teaching efficiency. In the information society, in a limited time, to get a lot of information and knowledge, which is unattainable in traditional teaching mode, multimedia and e-learning as a channel for the dissemination of information places, you can spread a lot of information at the same time Greatly improve teaching efficiency.
