With computer network technology specialty in higher vocational colleges, while the practical training is very important part of computer network technology specialty teaching. This combined with the current development trend of computer network technology specialty in higher vocational colleges, according to the characteristics of practical teaching, training course from the network setting up, network, training process, the network of ‘ practical aspects of network technology teaching an in-depth exploration of professional practice.
Due to the development of social information, makes the continued popularity of network applications, rapid development of network technology. With the rapid development of computer network technology, computer network almost every enterprise employees are closely related, from a corporate local area network plan, set up, run, and upgrades, to the website publication run, from management to network security and database administration, storage management, and network management systems such as the establishment, and associated computer network. Such extensive network of applications, computer network has become compulsory for many professional courses in higher vocational colleges. The practicality of the course is very strong, at the same time change and rapid development, endless stream of new knowledge, how to allow for a limited class has a strong practical skills of the students to the vast number of teachers is a great challenge. Here by the author in the discussion on practical teaching of computer network teaching experience and all, including curricula and teaching practice of computer network plan, teaching content and teaching methods.
Practice teaching curricula and teaching plans, computer networks.
Purpose of the course design of computer networks: is to enable students to study on comprehensive utilization of network knowledge, solve some practical problems, and to accomplish simple network management, the establishment, maintenance and so on. Prior to the formal lessons, Internet specific application in actual in networks, network development, conduct a detailed analysis of common problems in the application, develop practical syllabus. Comprehensive understanding of the situation of students the basics of premise, according to the syllabus to develop teaching plans. In formulating the teaching plan for the foundation of knowledge and learning ability of students in the process, to convert the contents of middle school students in this course is not easy to accept students of acceptable, and focused on training the practical ability of students.
Second, the content of the practical teaching of computer network.
(1) network basic practical training. The main purpose of such training is to train students ‘ ability to network set up to implement, requiring implementation processes through practical training for students familiar with network engineering and design, complete the construction of a small home office network. Main practice in this area are: twisted-pair production (the straight line and the line of intersection), ADSL Multi PC dial-up Internet access, shared Internet access through a broadband router, switch, basic configuration of the training, the cascade switch and link aggregation configuration, basic configuration using switch dividing VLAN, routers, etc. Through these practical training, students basic grasp of building a small home office network and network cabling basic networking skills.
(2) network management practice. This type of training is to train students for the purposes of network management capabilities to cope with the problem appears in the work. Practical training in this area are: software analysis of data on the network using packet capture tool, switch port mirroring, ports, and MAC address binding, VPN (virtual private network) configuration, IP address planning, based on the 802.1x AAA service configuration, monitoring and maintenance of network bandwidth, etc. Through these practical training, students basic mastering network device performance management, network management, network failure, authentication, billing, management skills in such areas.
(3) network comprehensive practical training. The main purpose of such training is to improve the network of student proficiency, meet the requirements of large and medium-sized enterprise networks. This aspects of real training main has: generated tree agreement of enabled, and three layer switch of VLAN interworking, and ACL access control list of configuration, and router static routing configuration, and router dynamic routing RIP configuration, and router dynamic routing OSPF configuration, and through single arm routing implementation VLAN between visits,, through real training makes students can master more in-depth of network technology, competent more complex of large and medium enterprise network management work.
(4) network security training. Such training aims to develop students ‘ network intrusion prevention, network security monitoring network attack skills, can deal with certain network intrusion and attack, acquire the relevant configuration method of network security equipment. Practical training content includes: Firewall transparent NET configuration mode configuration, firewall, Internet security policy authentication configuration, network monitoring, operating systems, data backup and disaster recovery. Through such training, enables students to master certain skills in network security-related.
Third, the practical teaching method of computer network.
How to make students interested in learning network practice class and like the network courses teaching methods is very important. In my teaching, primarily used by project, task-driven teaching method, grouping teaching methods, teaching methods, teaching method of questioning teaching approach and demonstration, through e-learning network, mainly leading task-driven teaching throughout the project, a variety of teaching methods. Teaching method of teaching method for the project, description of the project is to learn to use the Internet, for example. Practice teaching is the main purpose of the consolidation of theoretical knowledge, develop students ‘ hands-on ability, especially relevant professional’s ability to solve practical problems. Practical training teaching more highlighted this point, the most critical is the main training students practical training in the face of independent analysis, the ability to solve specific problems. Thus, in practice, to enhance the cultivation of students ‘ ability to troubleshoot. Intentionally set fault in the training, training team on its own address, teacher at the next prompt only, and does not give specific reasons.
Conclusion: development of computer networks quickly in order to do the practice teaching of computer network, as a teacher, we must keep abreast of the network to the actual situation, starting from a real network application explaining the formation of network, application, management and maintenance, and analysis issues, practical ability, and improve students ‘ ability to solve practical problems. At the same time, should focus on explaining the usefulness of content, to embody in the entire teaching “oriented by employment, student-basic” idea. Only in this way, to make reasonable teaching in the teaching, teaching can ease, to let students be taught this course is very useful for students interested in, and able to work quickly to put into their roles.
