项目摘要

In the science education, the characteristic of astronomy is that the scale of phenomena is huge. Students must move their viewpoints to the space far away from them when they study the astronomical phenomena. The acquisition of the concept which they can move their viewpoint is important not only to the science education but also to their growth. However, the educationist thought that it is difficult for children to acquire the concept.Therefore, we developed and practiced the following teaching materials. One of them is the material which the students can study about the relative positions of the earth, the venus and the sun using the webcast of the transit of the venus. The other is the material which they can study about the relative positions of the earth, the moon and the sun using the all sky webcast of the solar eclipse.The former is the material which the students can calculate an average distance between the earth and the sun (1 Astronomical Unit) from two images obtained at distant observing sites. In that case, the students move their viewpoints to the space of the solar system. The latter is the material which the students can have a virtual experience of the solar eclipse using real time and all sky projection on the planetarium dome. Almost people can feel the shade of the moon when they observe the total or annular solar eclipse. After examinees experienced the virtual solar eclipse, almost of them could feel the shade of the moon and could move easily their viewpoints to the space.

在科学教育中，天文学的特点是现象规模巨大。学生在研究天文现象时，必须把视点移到离他们较远的空间。获得能够打动他们观点的概念，不仅对科学教育，而且对他们的成长都是重要的。然而，教育家认为孩子们很难掌握这个概念。因此，我们开发并实践了以下教材。其中之一是学生可以通过金星凌日的网络直播来学习关于地球、金星和太阳的相对位置的材料。另一类是利用日食的全天网络直播，学习地球、月球和太阳的相对位置。前者是学生从遥远的观测点获取的两幅图像，可以计算出地球与太阳的平均距离(1个天文单位)。在这种情况下，学生们将他们的观点转移到太阳系的空间。后者是学生可以在天文馆穹顶上使用实时和全天投影来虚拟体验日食的材料。几乎人们在观察日全食或日环食时都能感觉到月亮的阴影。考生在体验了虚拟日食后，几乎都能感觉到月亮的阴影，可以很容易地将视点移到太空。
