Google Earth Mash-up 등고선 지도를 활용한 지형단원 수업의 효과 분석

Abstract

Contour lines are widely adopted as representation of terrain relief in traditional landform class. Yet, contour maps are difficult to comprehend for most students due to their abstract nature. It is hypothesized that the Google Earth could help students overcome these difficulties. This study was done by the following steps. First, four different types of landform were selected from high school textbooks: mountainous (highly elevated plateau, erosional basin), fluvial (terrace and incised meander), coastal terrace, parasitic volcano. Second, contour maps were uploaded into Google Earth using web-based mash-up services. Finally, the effectiveness of those materials is analysed through the four experimental classes at high school located in Kyunggi Province. In particular, integration among satellite data and digital maps takes advantage of each component, and enables the landform structures to be visualized, interacted with and deployed all on the Web. Google Earth based class ultimately brought out tremendous improvement on student? score and comprehension level. The classes using Google Earth can overcome the limitation that it is hard to take field trips and will draw the learners?interest in the geography class.
