地理資訊輔助等高線教學之設計研究

Abstract

地圖不僅是地理學研究教學上的有效工具，也是現代生活的重要資訊工具。在英、美、日等先進國家，地圖能力普遍被認為是國民所應該具備的基本能力；在台灣地圖知識和技能也被融入十二年一貫的地理課程中。等高線地圖是一種能有效且具教育性的表示地形起伏的地圖，即使是電子地圖如此發達的今日，等高線地圖的方便性及價值是無可取代的，然而閱讀等高線地圖對於老師及學生來說都是困難的。本研究利用地理資訊系統多元的展示能力，設計教材以輔助等高線教學。 本研究以準實驗研究法為基礎，利用實驗組與對照組進行等高線讀圖的研究。研究結果顯示學生的讀圖能力不高，在利用DTM繪製的彩色暈渲圖輔助教學，可增加學生閱讀等高線地圖的能力。

Map is not only an effective tool for geography research and teaching but important tool in modern life. In several countries such as the United Kingdom, U.S.A., and Japan map ability is generally considered as fundamental skill for all students. In Taiwan, map knowledge and skill has also been integrated into geographic curriculum for K-12 levels. Contour map is effective and informative in presenting terrain relief. In spite of recent development of digital maps, the convenience and value of contour maps cannot be replaced. However, reading contour map is a difficult task for teachers and students. This research takes advantage of the versatile representation provided by geographic information system and designs teaching material to assist contour instruction. Its aim is to raise the effects of learning contour and increase the ability of students’ reading maps. The study is based on quasi-experimental research. The performances of two experimental groups in contour map-reading are evaluated and compared. The result of this research shows that reading maps ability of these students is very limited. Using colorful hillshading maps created from DTM, this research shows that find such new representation of terrain can help enhance students’ ability in reading contour map.
