Research on Dynamic Visualization Teaching Method of Computer Network

According to the problems of Computer Network course, namely, knowledge is abstract, the teaching materials are complicated and ambiguous, the development of technology changes quickly, the learning burden is large, etc.. It introduced a virtual network teaching environment and mind map, so as to show the main network technologies and teaching resources of protocols by using virtual network environment and network typical cases, by using mind map to make teaching courseware in line with associative thinking process of the students. During the period of explaining concepts and protocols in classroom, it can use dynamic operation of the network teaching resources and network cases instead of the static network topology diagram, through Console, Wireshark, SocketTool and other tools, it can check network equipment and link information, subnet information and identification, network routing, network protocol, the state of network service, TCP/UDP port, as well as the contents of the packet of the specific data. Thus it can show the operation of network by means of dynamic interaction and visualization, so as to form a dynamic visual teaching method.
