Along with the fast development of global network technology information, traditional paper maps which record the various geography information of the earth's surface have begun to generate various forms and applications, including electronic maps, remote satellite images, global positioning systems (GPS), geography information systems (GIS) and so on. The application of electric and web maps has become greatly broadened. In the past, teachers tended to lecture; however, due to students' increasing computer ability, they have more chances to use computers. Therefore, the integration of these newly developed electric network maps into junior high geography curriculum is an essential topic for teachers and students. This article focuses on the topic of "Location and Range" in junior high school geography curriculum to demonstrate how to use free web software to increase accessible and practical information, as well as to design electric maps, such as UrMap, Google Maps, and Google Earth, pragmatic teaching plans/examples. In addition, teachers can teach students to understand how to read maps, describe relative and absolute locations, graphics, orientation, distance, and scale concepts. Because of the limited class time available for junior high school geography courses, this study further examines how students use electric maps at home for their winter vacation homework. Regarding to the degree of students' homework quality, whether students had computer equipment at home, students' ability to use computers, whether students' families provided support, the study analyzes individual student's learning attitude, and students access to such technologies. This study is a reference for junior high school teachers who would like to integrate electric maps into geography curricula.
