理科におけるコンピュータを用いた天文分野の授業事例

I teach science for the student of the junior high school second grader. To teach astronomy in a science class we use a planar photograph in a textbook or a collection of photographs. But, it is difficult for a student to image a dynamic movement of the star. Therefore, I used a superior computer software "StellaNavigator" and "Mitaka". When I use "StellaNavigator", it is easy to change a viewpoint and change a time scale, in an astronomy phenomenon. And we can easily watch a 3D image when we use "Mitaka". As a result, my students got interest in the space than before. My students were able to image an expanse of the space to some extent. However, I understood that it was necessary to make a model and to do positive class that does not passivize.
