Practice on Improving the "Computer Network" Teaching with Knowledge Visualization Representation

Knowledge visualization promotes the knowledge creation and knowledge transfer with various graphic visual representation means. According to the problems of universities in "Computer Network" teaching including abstract expounded theory and shortage of experimental equipment, and the updating can't keep up with the technical development, this thesis has presented the knowledge visualization solution, selected the knowledge map, mind mapping, Sniffer, OPNET and Packet Tracer as the tools for knowledge representation, to visual representation of " computer network" knowledge points, and introduced corresponding teaching samples. After tireless explorations and practices, it has obtained good teaching effect to adopt corresponding visualization representation tools according the "Computer Network" knowledge type.
