Development of new program for agricultural education by using the computer software Virtual Field System and the many movies recording plant growth

我们开发了一种新型的农业教育软件虚拟田地系统。该软件通过计算机图形学在一个假想的空间中绘制出三维的虚拟场。对于农场过于狭窄的小学和初中学生来说，作为补充农业经验的教材是有用的。学生可以直观地认识植物的生长速度和植物冠层内的光接收效率。本研究共拍摄了约50部记录植物生长（发芽、叶片、花朵、果实等生长）的影片。这些影片被认为可以作为农业教育的教材。这些电影的dvd被分发给许多老师在他们的课堂上使用。

We developed the new software Virtual Field System for agricultural education. This software draws the three-dimensional virtual field in a hypothetical space by computer graphics. It is useful as teaching materials for supplementing the agriculture experience of students who are studying at elementary school and junior high school with too narrow farm. The students can visually recognize the growth rate of plant and the light-reception efficiency within a plant canopy. In this research, about 50 movies recording plant growth (germination, growth of leaves, flowers, fruits, et al.) have been made. These movies are thought to be able to be used as teaching materials of agricultural education. The DVDs with these movies were distributed to the many teachers for using in their classes.
