Outline of Final Research Achievements

In learning the formation of mountains, the traditional concept of gradual changing due to weathering and erosion is changed to the new concept of instantaneous changing due to large-scale mountainous collapses and debris flow that occur at intervals of several hundred years. As basic data for this purpose, I divided the whole of Japan into four regions with significantly different geology and climate, and clarified the regional characteristics of mountain collapse. Then, in order to learn this effectively, I created a 3D topographical model that students can see and touch, and then project a geological map or satellite image at the time of collapse. This teaching materials allow students to experience the relationship between geology and mountainous topography. I We also developed a method for creating geological history teaching materials for teachers.

Academic Significance and Societal Importance of the Research Achievements

近年の集中豪雨などにより,自然が引き起こす激変が人間生活に大きな打撃を与えているが,従来は地域の自然景観の成り立ちは流水による侵食によって理解する学習となっていた。本研究は,このような考え方を,地質や気候による地域性も明らかした上で,山地崩壊とそれに続く土石流の絶大な役割を果たしているという考え方に基づくものに大きく転換するものである。これは,自然の見方や考え方を新しいものに転換するという理科教育の改善という面で大きな意義がある。同時に,地域性の強い土砂災害や水害に対して,地域の生徒たちがどのような災害リスクのある場所に住んでいるかを学習する機会にもなり,防災教育上も大きな意義がある。
