This paper from the perspective of educational technology development, analysis of the characteristics of online education, patterns, and the traditional relationship between school education and the development of online education.

1 development of educational technology
Recalling the history of human development of educational technology, according to the introduction of education in communication technology we divide it into three stages, as shown below.

As can be seen from Table 1, the dissemination of information technology each new stage of development will become the mainstream of educational technology, and gives the human ability to bring new educational activities to improve; and the introduction of education for each communication technologies, are all mode of spread of education had a great impact, such as the introduction of slide film, school education with electronic media, to promote improvement in the quality of education; the introduction of television, not only can improve the quality of school education, but also can use the TV coverage of the characteristics of to expand the scale of education; the introduction of computer multimedia, not only can improve the quality of education, expand the scale of education, but also by the help of individualized learning, the concept of individualized education more attainable. From this, school education content in a rich and constantly evolving, in the table we I, II, III.IV said.

The beginning of the new century, network technology, educational technology education is increasingly becoming the mainstream of development, and network technology education is currently in the initial application to explore when the network as a new communication technologies and resources to the introduction of modern education, the original educational environment, conception of education, educational models are likely to have a huge impact, but also will promote the deepening of education reform can be said that once the reforms are profound than any previous one, which is by the network and the characteristics of online education decision.

2 network and online education is characterized by
The development of science and technology, human society has grown exponentially in Xinxi Liang, and network technology has not only accelerated the growth of information, but also information in the world, different ethnic groups in the widely spread network of presents new information technologies and communication technologies, showing that the flow of knowledge and information-many of the diversified situation, a qualitative leap directly change the shape and spread of education, from technology to achieve the equitable dissemination of information to the public problems for the rapid development of educational technology to create a vast space to promote a new mode of education - online education the birth.


Web-based online education is environmental education. As the network technology itself is an open, interactive, resource sharing and other features, the network also has the traditional education school new and different characteristics.

2.1 The openness of the teaching system
2.1.1 The object of teaching the traditional openness of school education, teaching conditions, environmental constraints, the object of teaching is generally limited, and in a relatively closed and state-level development ladder. Is relatively closed to age-specific teaching task teaching object design, regardless of differences in how learners are generally only in accordance with the provisions of the corresponding year into the study, completed within the stipulated time to learn the task. ladder level that learners must develop basic, secondary, higher order of this development, insurmountable.

The teaching-learning system object is open, regardless of gender, health status, nationality, or rich and poor, as long as have a networked computer, learners can freely choose any professional interested in, any course of learning.

2.1.2 Teaching space of traditional education is generally open through the school, in the form of classroom teaching, the learner must be in school, within the specified time to complete specific learning tasks enable learners to online education can be connected to the Internet at anywhere, any time access to online resources for learning, learning content and can choose their own arrangements for learning programs at any time to learn the issues, and timely guidance and help, so online education space is open.'s open space of the learners in the learning behavior has a greater choice of autonomy.

2.2 rich teaching resources
2.2.1 multimedia, hypertext presentation of traditional education in the teaching resources were used to text, graphics, audio, video, animation and other media arranged in a linear way to present this presentation very systematic, but flexibility is not enough.

Online education in learning resources can be text, graphics, audio, video, animation and other media, assembled together in accordance with teaching needs, presented in hypertext, both systemic and flexibility that Web-based education, "can be the creation of a new concept in line with constructivist educational contexts, so that learners construct meaning better.

2.2.2 electronic library database as a resource library has a wealth of information resources is one of the greatest charm of the network, and network information resources are diverse, and it involves all areas of social life, in all disciplines. A shared network of information resources, No one is master of information for each network terminal learners, they are equal before the information. has a wealth of information resources can be shared, which is the network in the strong momentum of development education in the primary One of the reasons.

2.3 The teaching process interactive
Internet as a powerful Interactive Media, a variety of technologies to support online communication, communication is also a variety of teachers and students, between students and students can choose between different ways of interaction, as shown below .


2.4 The diversity of learning styles
The diversity of learning resources on the network, determines the diversity of learning styles of network learning methods are: individual learning, group collaborative learning, inquiry learning, discovery learning, etc. individualized learning is learner autonomy in the use of network resources learning, including self-selection, self-arranged time and place, during which you can ask someone for help, but learning to identify and complete tasks by themselves; group collaborative learning in general is the use of network resources as a team to learn, there is a clear division of labor within the group , share the learning outcomes; inquiry learning with a general theme chosen for the study, full use of network resources around the theme of discovery, exploration, research, students research and awareness, the spirit of science and innovation.

Although online education has many advantages, but the popularity of online education is, there are also many conditions. Such as purchase of computers, Internet hardware and software, network usage charges, the development of network resources, network of educators training, etc. universal education and network constraints are an important factor in development, but over time, economic development, modernization of education universal, and cost of these hardware problems will be solved step by step, online education will play an even greater potential.

Network hardware environment, network resources development, online education online education's training is the development of three aspects can not be ignored. According to foreign experience in the successful development of online education, the three inputs in the economy should be one-third each, the only way, the development of online education to be healthy and full of vitality.

3 mode of online education
3.1 Distance Education Network
The rapid development of network technology out of the university campus, use of public information platform to carry out teaching as possible, so there is a new form of education - Distance Education network. The emergence of Distance Education network of higher education full of new vigor and vitality, while also posed a challenge to traditional higher education.

Currently, the network of Distance Education are academic, non-degree and continuing education, etc., also some training for staff, and we used to call the University network. The United States as early as August 1998, California, Texas and other ten states to create a common virtual university, there are more than 80 universities offer Distance Education courses. In 1998 the network in July, Tsinghua University, Zhejiang, Hunan University, Beijing University of Posts and Telecommunications University of big four traditional distance education pilot project first began, opened a network of remote China education of the regiment. Since then, the network of distance education in the land of China, such as mushroom and flourish.

Classroom Web 3.2 Education
Online education classroom teachers in the classroom teaching the use of network information resources, creation of teaching situation, to impart scientific knowledge, the use of network technology tools in discussions and exchange, complete the curriculum prescribed teaching tasks. This mode of teaching to enrich and develop multimedia teaching portfolio in the form of classroom teaching in the media has added a new media that network.

How to include online media, including the combination of a variety of instructional media design, how to network with the organic integration of subject teaching, educational technology sector which is currently being studied and the whole education of a hot topic.

3.3 Network Support Education
Network as an educational media or resources, use the Internet to gather information, using computer technology processing, analysis, conclusion, and then released through the Internet or other media information network support education as the school classroom supplement for improving the quality of students has a unique role-based research study, collaborative learning, problem-solving learning belong to this category.


For example, Shanghai primary and secondary schools will be fully introduced research-based curriculum, which is a by students from their own social life around and ask questions to the teacher under the guidance of an individual or group to collect material, processing information, problem-solving approach to learning a new course . Nanjing Jinling High School, East Beijing Road Primary School, High School, Changzhou, Jiangsu Province, Nantong City, a middle schools have set up a research-based learning activities, courses, designed to use network resources to develop students' innovative spirit and practical ability to improve student overall quality.

3.4 Network-assisted education
CAPE campus based colleges and universities use for full-time students in credit repair online courses, community and schools jointly or independently design and development of school-campus courses for the primary and secondary services, these forms can be regarded as the school network, they have "school" common respect for the school's basic education law, such as teaching, planning, systematic, etc., with different distance education networks, it is the object of teaching a large primary and secondary students in the school. Wang Xiao is the online virtual school, is a new form of supplementary education schools, with universal, autonomous, modern features.

4 online education and traditional school education
Online education has many advantages, the timely transmission of information, network resource sharing, real-time or non real-time discussions and exchange of teaching space, unlimited expansion, the object of an unprecedented expansion of education, can effectively solve the difficulties of teaching in virtual reality, to promote education, social and the realization of lifelong learning, etc., all of which brought an excellent online education opportunities, but also made a lot of traditional educational challenges.

Requirements in this regard should focus on the traditional school of information technology applications in education, attention to information technology and curriculum integration, learn the strengths of online education, to make the existing education has made great progress and development on the other hand, for online education should be a very good standard, and develop appropriate industry standards in online education to the healthy and orderly development.

It is because of educational philosophy, educational methods, educational methods, educational diversity that makes the object of education is full of infinite charm, which makes the field of education Hundred Flowers Although online education can simulate the structure of traditional education, the interaction between teachers and students to construct multimedia teaching situation, but due to communication between people is through the machine and the Internet in the digital space, with the traditional school education compared to teachers and students exchange, friendship among students, the process of growing human environment and emotional climate, etc., online education seems not very friendly nature, so in the development of online education at the same time, people should be fully considered in the traditional process of school education of the accumulated experience, learn from each other, promote each other, ultimately merging and common development.

Whether it is traditional education or online education, their goal is common, it is to develop information society development and innovative talent, so the two should be a complementary co-existence between the two should be mutually reinforcing, complementary, integrated development together to build the new century, "Education Building" for the country's prosperity, national prosperity and contribute their strength.
