Keywords: information age, school teaching, network, network teaching, classroom teaching

Some people say that multimedia and information superhighway are two technical levers to push mankind into the information age. The development of the Internet, especially the appearance of the Internet, has integrated the social cells (multimedia computers and people who master computer technology) in the information age, realized the networking of human wisdom, and thus created a brand-new network culture.

Many schools have established campus networks to meet the needs of the times, connected to the Internet, and started online teaching. What is the significance of online teaching? What impact will it have on school teaching? What should we pay attention to in developing online teaching at present? This paper intends to make a preliminary discussion on these issues.

1. Developing network teaching is the inevitable choice of school education in the information age.

Education is an industry, and the quality of its products needs social testing. Without the social environment, there is no quality structure and training mode of talents. Similarly, network teaching is the product of the information age, and our discussion on network teaching must also proceed from the characteristics of the information age.

The characteristics of the information age can be summarized as follows:

1, "knowledge expansion", with a large amount of information;

2, the knowledge update speed is fast;

3. The competition for talents is fierce.

This puts forward higher requirements for education in the information society:

1, with divergent thinking, critical thinking and creative thinking, that is, creative talents with high innovation ability, rather than knowledge-based talents who only accept knowledge, remember and recite predecessors' experience, are not good at innovation and dare not innovate.

In fact, innovation is the "soul of progress" of any era, any country and any nation. In the information age, due to fierce competition, the requirement for innovative quality of talents is more urgent.

2. The trained talents should learn to recognize and have the ability to acquire, analyze and process information, that is, information ability. This is the most important knowledge structure and ability quality of talents needed in the information society.

In the information society, with abundant knowledge and rapid updating, learners must "learn selectively and continuously". It is impossible to learn some knowledge from teachers once and for all. It is better to teach people to fish than to teach them to fish. The wise choice should be to let students learn how to learn, how to find the knowledge they need in the ocean of information, and how to use various cognitive means to continuously acquire new knowledge so as to keep pace with the times.

3. Have a perfect lifelong education system.

The rapid updating of information requires learners to learn cognition on the one hand, and the society to build a perfect and convenient lifelong education system on the other hand, so that people can receive education freely and update their knowledge without being limited by time and space.

Education should greatly improve the quality and efficiency of teaching.

Similarly, due to the rich information, rapid updating and fierce competition for talents, education needs not only the quality structure of talents, but also the optimization of contents and methods, so that learners can receive education with high quality and efficiency.

To sum up, on the one hand, the information age puts forward special requirements for the quality structure of talents, the product of education; On the other hand, it also puts forward higher requirements for the level of education and the opportunity and convenience of education.

Because of computers and networks, we have entered the information society. At the same time, computers and networks also provide strong support for education in the information age.

Broadband network connects servers and multimedia computers and has the following characteristics:

Enjoy resources.

Enjoy services that are not limited by time and space (the server has memory function, 24-hour service and extensive network).

Can quickly transmit all kinds of media information (broadband network and multimedia computer cooperation can transmit all kinds of media information)

Multi-directional communication (multi-directional transmission of information)

After these characteristics are used in education, they can bring the following benefits to education:

1, * * * Enjoy educational information (resource appreciation) 2. Nothing 3. Limited by time and space (more educational opportunities 4. More convenient learning 5. Convenient realization of national education and lifelong education) 6. Multimedia multi-sensory stimulation effect 7. Super connection 8. Convenient communication 9. Convenient cooperation, consultation and help.

These are undoubtedly great support for education in the information age.

First of all, the characteristics of the network, such as large amount of information, convenient information transmission and strong interaction, are conducive to the development of discovery-based and collaborative teaching, and cultivate students' ability to ask and solve problems, thus contributing to the cultivation of students' innovative ability.

Secondly, the network is the most effective information acquisition tool in the information society. Carrying out network teaching is conducive to cultivating students' ability to obtain, analyze and process information by using the network, and to cultivating students' information ability.

Thirdly, developing online distance education is the most effective way for national education and lifelong education in the information age.

Finally, the huge information resources, superior multimedia functions and multi-directional interactive functions of the network make it possible to improve teaching quality and efficiency.

What we are facing is an era in which network services are improving day by day and education is highly informationized. Developing network teaching is the need of the times and the inevitable choice of school teaching.

Second, the new changes and new features brought by online teaching to school teaching:

1, campus digitalization

With the development of network teaching, the school will gradually form a digital campus environment relying on campus network. Including the collection, production and management system of teaching resources, teaching management system (including teaching plan, curriculum arrangement, student management, examination results audit, extension examination application, etc. ), electronic campus (including real-time teaching, on-demand, answering questions, homework submission system and digital library, etc. ) and so on.

2. Scientific teaching materials.

According to the teaching theory and communication theory, making full use of the multimedia and hyperconnection characteristics of the network, online teaching materials will tend to be multimedia and nonlinear; More importantly, online teaching materials are updated quickly and can keep up with the times. This will be beneficial to learners' meaning construction and the improvement of teaching quality.

3. Students' subjectivity

Students have changed from passive acceptance of knowledge to cognitive subject, from passive learning to active learning, from rote learning to learning with tasks to solve practical problems, and from gradual learning to self-paced learning. It is conducive to the cultivation of students' innovative ability and information ability.

Teachers' role will gradually change from imparting knowledge in traditional classroom teaching to organizer and assembler of information, and become guides, helpers and promoters of students' learning, not "saints in the pulpit", but close friends and "guides" of students.

4. Diversified forms of teaching organization.

It breaks through the traditional "class teaching system", which is a single teaching organization form, and makes individual learning, collaborative learning, classroom teaching, distance network teaching and other forms coexist, greatly improving the teaching quality and efficiency.

5. Rationalization of students' quality

The development of network teaching is conducive to cultivating learners' innovative ability and information ability, and making students' quality structure more scientific and reasonable.

6. Open schools.

The traditional "school" is a school confined within the fence. Radio and TV teaching has broken through this mode, and the development of network teaching, especially long-distance network teaching, has completely changed the concept of "school" and made the school an open, virtual and socialized school. It provides conditions for national education and lifelong education.

3. Some thoughts on the current network teaching in schools.

Combined with the current situation of online teaching in our schools and our online teaching practice, the following points are worthy of attention:

1, raise awareness, 2, boldly practice, 3, dare to take the first step.

Developing network teaching is the general trend. In any case, we are about to face an era in which the Internet is ubiquitous. Therefore, all possible schools should create conditions to carry out online teaching.

On the issue of developing online teaching, we should be less hesitant, practice boldly and take the first step. It can take the form of grasping demonstration classes, making key breakthroughs and seeking development while doing.

4. provide conditions, 5. Self pressure, 6. Create a high-level educational technology institution.

The competent department of network teaching (educational technology center for short) is the researcher, manager, training supervisor and guarantor of network teaching in schools and plays a leading role. Therefore, the level of educational technology center directly affects the normal development of online teaching. Educational technology center should press itself, concentrate on research, communicate widely, and attach importance to theoretical research and applied research of online teaching. School leaders should attach great importance to this and provide conditions for the investigation of educational technology centers.

Only in this way can the educational technology center formulate a scientific development planning and evaluation system and implement effective training and guidance; Only in this way can we provide strong technical support for the development of online teaching.

7, the use of modern educational technology

8. Conduct online teaching, training and discussion.

The development of online education puts forward new and higher requirements for both teachers and students. Educational technology institutions should constantly train and discuss the network teaching for teachers, which can include the basic theory of modern education, the theory and method of teaching design, the use of multimedia computers and the compilation of courseware, the use of multimedia computer networks, the download of online information, the design of web pages, the development of online teaching information, and the network teaching mode. Of course, the best way is to use the internet to carry out training, which is more real, effective and convincing.

Deng Xiaoping said: Computers should start with dolls. At present, in order to meet the needs of the information age and cultivate information talents, the United States, Britain, France, Singapore, Taiwan Province Province and Hong Kong have listed computer-based information science as the main course in kindergartens, primary schools and middle schools, and the mainland of China will also offer information technology courses in middle schools in 20001year. This is of great benefit to the follow-up network teaching.

9. Pay attention to the development of network functions, 10, and provide technical support for network teaching.

After the completion of the network, only by continuously developing its functions can we provide effective technical support for teaching. After the completion of campus network in some colleges and universities, it is only used as a tool for file transmission, and the network operation efficiency is extremely low, which is not only a huge waste, but also brings technical obstacles to the development of network teaching.

At present, we have summarized the following eight online teaching methods:

Video playback: the network management center plays video (real-time video or video). This form is not much different from TV or playing video, and students can't control it. In fact, it is a live classroom teaching. Its advantages are that learners are not limited by region and number of people, and occupy a small bandwidth (only 1.37M), which is mostly used for lectures by famous teachers, academic reports, live broadcasts of important conferences, etc.

Video on demand: learners can request videos from the server as needed. The content can be a TV teaching film or a live video in class. Because it is not real-time on-demand, we can carefully design (insert pictures, words, videos, animations, etc. NVP (Network Video Presenter) is a kind of video on demand. Its advantage is to play electronic slides synchronously on the basis of teaching video and audio information. It is a secondary development on the basis of ordinary video on demand, which is conducive to transmitting teaching information more effectively.

Video conference: a form of multi-directional real-time transmission of video and audio. Because the equipment is expensive, it is not widely used, and it is mostly used for teachers to answer questions.

Network teaching materials: make the teaching content into the form of web pages. Its advantages are not difficult to compile and simple to operate, so it is widely used.

Multimedia courseware: Textbooks developed by using multimedia language or courseware development tools are generally downloaded to this machine for running.

BBS Forum: Teachers communicate and cooperate with students and learners in the form of bulletin board system;

Chat room (teaching discussion area): teachers and students communicate with learners in different places in real time through text, voice and other forms;

E-mail: teachers communicate with students and learners in the form of e-mail;

There are other ways that need further development. In short, we should rely on the campus network to create a digital campus environment, comprehensively use various teaching methods, give full play to the advantages of online teaching, and obtain the best teaching effect.

1 1, adopt various ways, 12, and enrich online teaching resources.

At present, the lack of systematic and high-quality online teaching resources has seriously affected the development of online teaching. Schools should take enriching online teaching resources as the central task of current online teaching.

To enrich teaching resources, we should adhere to the principle of multi-channel collection and pragmatic development. There are mainly the following ways:

Procurement: the production and operation of enterprise groups.

Distribution: production under the unified organization of the education management department,

Communication: mutual communication between brother units and peers.

Cooperation: the cooperative development of audio-visual education professionals in educational research departments, universities, primary and secondary schools and front-line teachers or the cooperation between peers;

Self-control: self-development of front-line teachers

13, focusing on teaching design,

14 as the lifeline of online teaching.

Network is only a channel for information transmission, a technical means and a local factor in teaching. The key to the quality of online teaching lies in teaching ideas, teaching strategies and teaching methods. We must take the teaching design based on teaching theory, communication and system science as the first element to carry out online teaching and regard it as the lifeline of online teaching.

15, pragmatic,

16, adhere to the talent training as the center.

Probably no one would have thought that due to the many advantages of online teaching, traditional classroom teaching would withdraw from the historical stage.

In 19 1 1, Edison predicted: "In school, textbooks will soon become obsolete, and soon, students will learn through vision. It is possible to teach every branch of human knowledge with movies. 10 years later, our educational system will be completely changed. " Nearly a century has passed, and this prediction has come true. Similarly, we can't say that the traditional classroom teaching mode will soon be replaced by the emerging network teaching, because the traditional classroom teaching and network teaching have their own advantages and disadvantages.

The traditional classroom teaching mode has its obvious advantages: it is conducive to the leading role of teachers, to the organization, management and regulation of the teaching process, with low requirements for the construction of teaching environment and high teaching efficiency. More importantly, interpersonal communication between teachers and students has a far greater effect on students' growth than classroom teaching itself. At present, online teaching is not perfect:

1 The teaching effect of online teaching on emotional goal 2 (such as ideological quality and psychological quality, etc.). ) and motor skills goal 3 (such as sports, experiments, surgical skills, etc.). ) is not ideal. Learners' self-control is influenced by age and learning style. For younger learners who are more dependent on learning, 6 requires higher teacher-led role, while 7 is not suitable for autonomous learning through the network. 9 teaching equipment 10 has high requirements. The communication cost of 1 1 current 12 is high.

However, we believe that with the advancement of educational informationization and the continuous development of online teaching technology in China, online teaching will meet the needs of teaching more and more, and will become a mainstream teaching method.

Network teaching is an important choice for school education in the information age. The development of network teaching has brought earth-shaking changes to school teaching. Schools should actively create conditions and boldly set foot in online teaching. But at the same time, the advantages of traditional classroom teaching should not be completely denied. Schools should give full play to the unique humanistic and emotional atmosphere, pay attention to the optimal design of teaching, seek the best combination of classroom teaching and network teaching, and cultivate high-quality and efficient new talents to meet the requirements of the times and meet the needs of 2 1 century.
