The most widely-used typical information service of national education, EDUNET has members of 5.8million. But it has been not used in the fields of elementary school. There are short-comings in its usage by members of the elementary school teaching. We would like to find solutions by using a questionnaire to the teachers of elementary school in the Busan and Gyeongsangnam-do, which resolve the problems of the actual condition. Analytical results show that 93.1 percent of the teachers usually use private education information service and 5.3 percent use EDUNET service. The main reason why teachers discourage the use of EDUNET service is that it provides the inconvenience of searching data(29.4%) and insufficiency of good quality contents(25%). In order to revitalize using EDUNET service, EDUNET has to improve on the perceived cumbersome unhandy of searching tools and help teachers to use EDUNET service by offering information of high quality.
