Analysis of how cloud computing technology should be used in education

Mr. Ren is a member of the Cloud Computing Experts Committee of China Electronic Society of Modern Education Technology Branch, the deputy director of Guizhou Province Audio-visual Education Museum, the senior experimental teacher, the Guizhou Educational Association Modern education Technology Specialized committee vice President, Secretary General. For us to do a topic for "the sharing of high-quality resources, cloud-led education innovation" speech. In his speech, he first introduced the background of education informatization in Guizhou Province, introduced the current construction situation of cloud platform, introduced the operation management of cloud platform, and finally gave the prospect of the future of cloud computing in the field of education. Here is the content of the speech.

Analysis of educational informatization level in Guizhou Province

Ren first introduced the situation of the education field in Guizhou Province. Guizhou Province primary and secondary schools have 14497, students have more than 6 million people, computer vitality than 55:1, in the country is in the level of small and medium tourism. At the end of 2012, it is expected that all schools and colleges will be fully connected to the Internet, and the provincial and municipal education administration departments and all universities should be completed. At present, Guizhou Province is the first education special network of the province. Private network currently only opened High-definition Video conferencing system and the operation of the province's education Automation Office system.

As the information of education in Guizhou County, from less developed areas, should be said to be resident growth and development, there are some problems, now I have a brief talk about the problem. One is the information Development Fund, the safeguard mechanism has now formed, has already formed in the whole country. We hope that this year will soon be the National Education Information Advancement Conference, the work also raised this issue, the province of this situation is also more serious. School equipment can not be effectively used, mainly speaking terminals. The third problem is the lack of educational digital resources, the fourth is to share quality education resources, refers to all teachers, all the students share resources more difficult. Another is that network resources digital security has some loopholes, this is the basic situation of our province.

This distance education and multimedia resources into the classroom is the core content of education informatization, now the development of education information, promote education information, one is organic education, one is the multimedia resources into the classroom, this is the core of primary and secondary education information.

From the aspect of distance education, distance education based on this network education technology, he wants to achieve three goals, one is continuing education, one is lifelong education, one is the quality of resource sharing.

What problems do we face in distance education? Although the Guizhou province has done more than 10 years of distance education, primary and secondary school distance education, but also the national pilot units, to this year a full 11 years. Now faced with the problem, one is that the future trend of attention is not enough, then a cross-regional information resources sharing, the cross-regional in the province, such as central schools and counties and rural schools, as information resources to share more difficult. One is the lack of technical personnel, this time in some education work, there have been a lot of equipment broken down, also no use. What's the reason? The teacher who managed the equipment transferred away. Another is that all levels of attention to the hardware scale and neglect of the application, their own constantly built, build how many schools, how many classes and classrooms, how many campus network, which is the development of education information.

Again a rural broadband is seriously insufficient, another is the management cost is too high, this management cost has the technical problem, runs some educational resources, for example a school needs a set, 10 schools need 10 sets, this management cost is higher. Another resource platform utilization is not high, now the resource platform we take the region as the unit, the province has a resource center, the region also has the resource center. In response to these problems, we have summed up four aspects of the root causes, one is really innovative educational applications, the second is the centralized sharing platform applications, the third centralized unified infrastructure platform, the fourth is the support of professional and service. This raises many questions, in the future our network education already appeared certain scale, how to carry out further?

First of all, to build an advanced platform, is a cloud platform. From decentralized to centralized integration, using cloud computing technology, building public storage disaster preparedness, computing, sharing broadband, security certification cloud platform.

Extraction of high-quality resources, the establishment of independent service portal, to achieve a total of high-quality resources, the establishment of a regular use of the province's overall education resources such a platform. Another is the innovation model, with our own, our technical force to support such a link, we think of a third-party professional services companies to operate, schools participate in such a new model. The so-called school participation, the school is in the name of application to participate in the new model. We build the principle that we first need to protect the existing model, the whole of our provincial Education Department this room we invested 4 million to build such a room, we build this cloud we have a new commitment to our less developed provinces this is a large amount of money, it is not easy to do.

Another invitation to have advanced technology, is technology has advanced, the third is to economic and practical, the fourth is controllable security. We take such a train of thought, we set up an advanced technology platform, we have established our Guizhou Province education.

I later inquired that this provincial education in our country in Guizhou province is the first, according to our previous thinking, we built a national provincial education, the entire structure we were completed last November, and now we are doing some deployment of applications.

The construction of education cloud Platform

The following is a detailed introduction to the construction of education cloud platform in Guizhou province.

First of all, we have a number of characteristics of cloud platform construction: The first one is its originality, just now we talked about the idea of the cloud platform to protect the original input, because in our cloud platform above we use some can not be broken application platform and system, after this we ask the third party technology to support the company, put forward such a request. Then they solved the problem effectively. First of all, we build cloud storage, a unified data-sharing storage pool. Concentrate all of the storage units that we don't have enough systems. We use the old hardware architecture to build a pool of computer resources.

The third is our comprehensive application system migration, is the overall migration, this is our set of systems, we build the cloud platform, we put the original all our operating platform, the overall migration to our new cloud platform. We said this time built, did not have an impact on our work, and easily rise to the clouds, this is our cloud construction characteristics, but also our original place.

The fourth one is to establish a unified authentication autonomous service system, which is to consider our entire cloud has a controllable.

This is our original structure, we look at the original architecture we have a management system, there are high-end self-service systems, there are distance education sites. We have some application platforms and some systems. Here every system, from this frame look is the only existence, its service, its storage, are the only existence. We in such a original frame, the original situation we finally unified it to a cloud collar, unified storage, services all unified. We first unify in a cloud storage system, we unify the storage system; then one is our service system, our server, service pipe, system service also unify. In this way the cloud platform is built, the biggest feature of this cloud platform is to expand by region, at any time.

The third feature is the practicality, mainly on demand resources, our users come in, we each school, teachers to come in according to our program come in, very simply came in, this management we are unified management. And then based on our cloud storage teaching resource library, we have to ensure that access quickly, fast computing, in our cloud can be achieved. Then we have a large-scale live classroom based on the cloud platform, I do not start here, each of our schools in the cloud after registration, you can take classes, recording, and live, in our cloud all schools, all points can be seen.

Another is on-demand system, we all share resources, in our cloud all users can be directly on demand, that is, each of our schools can see all the resources. This is our "three excellent" evaluation system, is excellent paper, quality class, excellent courseware, this review every province we have to do, this thing has not yet set up this education cloud, this thing is very troublesome, to take photos, to spend a lot of financial resources, manpower, material resources to solve this problem, and now we are on the Internet "Three excellent" review, our time is not limited, the location is not limited, experts can use their own control of the platform to review, high quality.

Another school safety management system, this is the Ministry of Education Information System, in our Guizhou platform. This operation management we take the government agency, the third party specialized organization service, the school participates in such a pattern, we in the technical support aspect obtains the Beijing Technology Limited Company to give us the massive support, has done a lot of help for our technology support.

and its advantages, how many advantages. Then is the results, the future of our development thinking, I was prepared to build such a system, one is the management system, one is the teacher education system, one is the virtual laboratory teaching system, this virtual laboratory teaching system is particularly important, there is interactive teaching.

Finally, I would like to pass this meeting, there is a proposal is also an advocate to complete the construction of the cloud I think is a standard question, I think the country's education cloud, now study this problem is very good, regional clouds and the contrast between clouds, this docking standard and docking agreement. Now the state constructs the cloud, and we all put our things in the system of our national cloud, our new cloud to build us, the level of deployment of our region, I think this kind of realization is not very likely, also very troublesome. I feel the docking between cloud and cloud, docking standards and interface standards. After this area cloud is built up, become the national cloud, the whole nation joins up again.
