GISを用いた地形教育のためのオープン教材の試作と評価

抄録

School and university teachers have been developing educational materials using GIS for geomorphology classes. However, these materials often have limitations such as the lack of systematic contents. Therefore we have been developing new online materials for geomorphology education using GIS. The learning topics were selected for high school students and university freshmen and sophomores belonging to geography or teacher training courses. The materials explain geomorphology systematically using text corresponding to high school geography textbooks and WebGIS built with open source technologies: Leaflet and CesiumJS. Students are expected to understand how to read topographic maps and identify typical terrain types, by operating simple 2D or 3D digital maps. We conducted an online geography course for university students using the materials and a subsequent questionnaire survey including a test of map interpretation to evaluate the usability and learning effects of the materials. We also conducted another questionnaire survey for high school students to collect their opinions related to the usability of 3D maps. The results indicate that our materials improve the understanding of students about landforms. On the other hand, they felt difficulties in detecting landform types because they could not clearly connect map reading with their prior knowledge. These findings are useful for improving the educational materials by adding explanations and operational functions to understand landforms more effectively.
