Studying networking technologies have become one of the most important subjects in the field of technology in junior high schools and information study of senior high schools in Japan. A problem with studying networking technologies is that there are few intuitive educational equipment for these studies. In addition, network systems have become an infrastructure of society. It is difficult for students to imagine network systems and technologies because they cannot see how networks work. The new educational equipment of a network router for network construction based on the concepts of physical visualizations and physical direct manipulations has been developed. The equipment can visualize how networks work using a Full Color Serial LED tape. Additionally, the equipment provides function of physical direct manipulation using dials and buttons. The experiments were conducted using the equipment and confirmed that the equipment works effectively for network learning.
