British technology forecasting expert James Martin's results show that: the knowledge of mankind in the 19th century, doubling every 50 years to the early 20th century is doubling every 10 years, 70 years is the increasing power doubled every 5 years, while Over the past 10 years is about to double every 3 years.
With this change, schools of education should not limited to the established materials and traditional learning methods, teaching should be adapted to provide digital changing demands of the times. At present, the focus of education is from the traditional exam-oriented education to quality education and transformation, quality of education as the basis for raising China's overall national strength is essential works.
NPC High School: create a new "digital" high school
Into RDFZ, East Academic Building has become from the U-shaped lip, which had also grown a layer of four-story dining hall, saw Central Park into a center lawn. Learning time in the most simple, the students are growing slowly, while the NPC middle school teachers from a single one-on-one education of students gradually develop into a single network of information and more on education.
Multi-media teaching in 1995.
1998 online teaching.
In 1999, the National People's Congress High School and the New York State University and the Kansas schools, Leighton Centre, a web-based multimedia interactive distance learning tests.
Opened in 2001 with Japan's distance learning activities. In addition, the National People's Congress also opened a school affiliated with Beijing suburban districts and counties of the ten distance learning in secondary schools. Rely on advanced distance education technologies, educational advantages to RDFZ across time and space, out of Beijing, out of China, extending to the world; on the other hand, the NPC was established in 1998 High School 100M Fast Ethernet switching network,
Launched in 2001 Digital Campus project, forming a six buildings, 400 point level information, more than 600 networked PC, 10 units specialized server prototype of a digital campus.
NPC High School in 2002 with further ideas, I hope RDFZ the digital campus network capable of teaching, learning, research, management and the five major life functions, in addition to a web technology-based, service-oriented applications of digital campus network, can also provide more network services, thereby saving costs and increase network efficiency.
New internal and external protection: firewall and waterproof wall
In the "Zonta, learned, innovation, pragmatism," the school motto under the guidance of High School Affiliated to Renmin University of China for the teaching and management of IT technologies rely more and more obvious that the existing products and network architectures can not meet the National People's Congress has clearly achieved High School high degree of digital campus network and occupation of the commanding height of modern educational technology requirements, and, early on Fast Ethernet switching technology making the middle school campus network security and management there are many deficiencies.
In the end what kind of network? RDFZ hub Wang Bin, director, said: "RDFZ teaching and research of information technology to advance with the times, with the teaching methods and modern management tools, we are building a Digital Campus put forward higher requirements for RDFZ need a highly intelligent and forward-looking network. "
Although the completion of the NPC Campus High School High School for the NPC provides a fresh way of teaching, and distance education, "Online High School National People's Congress," the progressive development of shape. However, the NPC middle school construction process in the information the device has three to four purchases, the brand is very complex and involved, and because the time period purchases different, resulting product is not complete, level is not uniform, the overall network is not uniform planning, resulting in more serious viruses throughout the network.
With a network of large applications, RDFZ gradually began to fret nuisance virus, network virus outbreaks often very easy to crash the entire network, and for distance education, once a charge of distance education, we must ensure the quality and service, and frequent network problems, making distance education and the construction of campus networks difficult. A large number of network management for network maintenance personnel work miserable, using several different anti-virus software, virus database is updated daily to become a required course work network. But even so, it can not be a good support network run smoothly. With the network scale and traffic increases, the exchange of bandwidth and the stability of network operation into a deadly bottleneck, especially security If no guarantee on the whole distance education Laishui is a "bomb".
After the initial contact and understanding, Digital Network Expert advice given is: because the virus is spread through the switch is not spread through the network, it is used for the control of the virus outside of the firewall and the internal wall of water. From the customer to switch and the network layer security, whether intranet or extranet, or the spread within the network are all real-time monitoring system, the virus shield on the switch, the switch will be detected in the unit of time will kill dead virus, so as to effectively control the campus network virus. If there is intrusion, the administrator can determine according to scale, this information to the network management personnel to determine whether he closed, you can judge by the machine shut down.
After a long at home and abroad contact the manufacturer, RDFZ finalized Digital China Networks solution was chosen because the program's third generation of service-based campus network design ideas, 3D-SMP and other advanced product technology has also the continuous development of teaching and management to provide quality services.
Five features innovative network platform
Psychologist Pa Bote said, "digital media on a real contribution to education is because it has the flexibility and tension, it allows each individual can find their way to learn." RDFZ construction is aimed at Digital Campus In order to carry forward through the network to maximize individual student learning.
September 2004, the NPC began to transform the middle school project discussion, formulated a clear plan and detailed objectives, is to ask the National People's Congress of Digital High School campus network capable of teaching, learning, research, management, and five functions of life.
RDFZ network transformation project, ostensibly to see the transformation of the network equipment, in fact, involves the upper network, including a directory of campus internal management and future scalability. Because high school campus to replace the relatively long period, taking into account the IPV6 RDFZ access, to the experimental network and the dormitory network node as a sharing of resources used in the project trunk, below this layer are taken into account Gigabit access.
In teaching management, the NPC has reached a middle school teacher of a small system goal. Learning platform in the Institute, teachers can teach in this platform to do some evaluation system and a small forum, students do the work to the teacher through the marking of these platforms to achieve the student teacher in learning management and education. And school teachers use what platform, how lesson planning, management systems on campus, or student management system, are given full freedom.
In the study, scientific research, teachers are free through this platform of resources in the school library search courseware information, save the management of learning materials and student information, you can also customize the outside through the platform to some of the information used as scientific research. Director Wang explained: "For example, in papers that can be selected on the platform to do a regional specialized papers, as well as Teaching and Research Group internal information, as well as lesson plans developed Planning casually." Students can access the library at school, check on-line information and reading in schools Electronic books.
Meanwhile, schools are built digital campus network, is also usually support the learning and life of the basic business and multimedia applications: College for providing virtual private network access VPN, series of online business, including the campus card, online video, digital books Hall, unified messaging, helping RDFZ teaching, learning, life and management to a new level.
In 2006, the National People's Congress opened middle school, "Basic Education Information Platform." With this platform, the NPC middle school teachers and students retrieve from the Internet, databases and other learning materials in all directions, online reading the latest books, teachers and students online answer, enjoy the classic English plays on demand - the learning of information technology, the NPC's High School teachers and students only need to click the mouse you can easily achieve. In the future, the school's training, courseware will be 鐢?video playing, and 閫氳繃 user management system, user authentication system, AD shared directory practice management, Dadaorenhe a user Jinruzhege Wangluo Zhihouduneng record his online behavior.
Now, the platform on teaching, learning, research, management, and the five major life functions, the National People's Congress has been to create a new middle school teaching methods, teachers, before the questions for the class for students with problems themselves, find related information to the Internet , draw their own conclusions, and then return to the classroom teacher to answer the question. Students can also find the information according to their own questions to the teachers to create an interactive atmosphere.
Campus information technology as a national advanced unit in 2005 RDFZ also take a "basic education on the national grid IPV6 Model" topic. The subject of a theme initiated and set up a "national basic education 璧勬簮 Sharing Alliance", for the majority of primary and secondary schools, focusing on rural-oriented, with primary and secondary education in modern Yuan Cheng Implementing the project to provide Manzu CD teaching, satellite TV education, network models of high-quality education resources for basic education and public education resources, the demonstration of long-term education project.
The new design highlights the three areas: security, stability, management
Taking into account all factors of campus network, Digital developed a program based on its characteristics.
Building a good information system should follow the "master plan, step by step" principle, the top is a custom target, full of personality, but that there must be unity as the basis for the underlying support.
According to this idea, Digital's network transformation program will be divided into RDFZ scientific areas within the network, DMZ area and outside the network area in three different areas. Intranet network using two Digital Routing Switch DCRS-7515 as a dual-core, the original 8600 switch as a service group within the network core switch, the convergence layer of the DCRS-5512GC 12-port Gigabit routing switches, switching layer 24 Stackable Smart replacement DCS-3926S for the students and staff to intelligent network access; DMZ area DCRS-7504 with a core routing switch for the DMZ area service groups to provide high-speed data exchange. The management of the network, using the Link Manager network management software running on the device and network management to visualize, through DCBI-3000 provides a secure and flexible access to certification services.
The program reflects the complete system security, stability and a good network of good management.
Complete system security. 3D-SMP provides sophisticated network security linkage. Authentication, access control list (ACL), TELNET service restrictions, SYSLOG event record system, content security filtering, RADIUS, multiple access control and other security mechanisms to provide a complete system security.
Good network stability. Backup redundant dual core technology, when the network link or device failure occurs, the network returned to normal in a short time. OSPF network using standard protocols, you can in 30 seconds in the entire network by the convergence.
Of good management. All Digital Networks products support three kinds of network management: command line, Web, and Link Manager network management software. Digital China network, the command line easy to use and helpful features, you can make all the configuration work. Web browser management interface is graphical, intuitive and simple. Link Manager network management software can be run separately in the Windows NT platform, you can use with the HP Open view matching.
Now, Virtual High School students through the National People's Congress on the physical science laboratory class, the teacher had finished, students can experience through virtual technology the gravitational interaction of the solar system planets. Lab teacher, said: "With advanced virtual technology, students can simulate and create real-life experience can not be directly observed physical phenomena to explore the many mysteries of nature. The probe by the same syringe, students can be real life collection of objects in a variety of data to the computer to simulate three-dimensional images of objects, and carry out any processing. "
