傳統的紙張地圖記載著地表上各種地理現象的位置與範圍，但隨著全球網路科技資訊的快速發展，資料傳送速度變快，在網路呈現圖形和地圖的可行性相對變高，網路地圖的應用和使用層面將會更爲廣泛。以往教師多採單向的講述教學法，但是考量現在學生的電腦能力普遍提升，接觸使用電腦的機率增加，應該善用這些新興的網路電子地圖融入國中地理科課程中，將成爲教師教學與學生學習的好幫手。本文針對國中地理課程的主題『位置與範圍』，利用網路免費軟體增加資訊的可用性，並藉由常用的電子地圖UrMap、Google Maps與Google Earth，設計生活化的教學範例，教導學生更能夠清楚的掌握地圖的判讀、相對與絕對位置的描述方式、網格座標、方位、距離、比例尺等都是重要觀念。爲因應當前國中地理課程授課時數之不足，本研究進一步讓學生利用寒假的地圖作業在家中自行操作電子地圖。藉由學生繳交作業的情形，除了評估了學生家中有無電腦設備，個人使用電腦的能力，與家人是否給予協助等的可行性條件外，也分析了學生個人學習態度積極與否，沒有電腦設備圖資時會如何取得等，嘗試解決問題的能力，值得想用這些網路電子地圖融入國中地理科的教師們參考。

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.
