A study on effective using of the fast internet in earth science and astronomy education

首先，首席研究员从教育中计算机使用的报告中证明了互联网通信在地球科学和天文学教育中更有效。其次，我们新开发了一种在计算机上绘制三维地形地质图的方法，并报告了其教学效果。作为一项主要活动，我们制作了许多有效的网络电影（640x480像素大小），可用于中学（初中和高中）的地球科学和天文学学习，这些电影已上传到网络流媒体服务器上，并已向学校开放。学校教师指出，在他们的学校里，电脑上的电影流不那么流畅。这是由于硬件不足，如旧机器或网络缓慢，这些学校。解决这个问题的一个可能的办法可能取决于未来教育机构的财政支持。作为另一项主要活动，我们新开发了通过望远镜的天文图像的互联网中继系统，以及交互式通信（电视会议）的子系统。在教学实践中，学生通过该系统了解了太阳、金星等天体的特征和活动。此外，他们对与大学的互动交流也留下了深刻的印象。特别是要关注互联网上的这种互动交流。最后，作为高分辨率图像（1280x720像素）网络传输的初步尝试，我们制作了一个望远镜拍摄的月球图像高分辨率视频。通过在中小学使用高清电影的一些实践，学生们可以认识到月球表面的地形特征和观察物体的细节。认为高清电影作为教学媒体，更能有效地展示自然事物和自然现象。

At First, the head investigator has demonstrated that the internet communication is more effective in earth science and astronomy education from reports on computer usage in the education. Next, we have newly developed a process for drawing of 3 dimensional topographic and geologic maps on computer, and reported those educational effects. As a main activity, we produced many effective web movies (640x480 pixels size) available in earth science and astronomy learning in secondary schools (junior and senior high-schools), which have been uploaded on a web-streaming server and have been opened to schools. School teachers have pointed out that the flow of movies were less smooth on computer in their schools. It is cause by insufficient hardware, such as old machines or slow network, of those schools. A possible solution for the problem may depend on financial support from educational concern in future.As another main activity, we have newly developed the internet relay system of astronomical image through a telescope, with a sub-system for interactive communication (TV conference). Throughout some educational practices with using the system, pupils have realized feature and activities of astronomical objects, such as sun and Venus relayed. Besides, they have shown much impression for the interactive communication with the University. It is important to focus especially on such kind of interactive communication on the internet. On the fast internet, it will be easier and more smooth.Finally, as a preliminary to the internet relay of hi-vision image (1280x720 pixels size), we have produced hi-vision movie of moon image through a telescope. Throughout some practice using the hi-vision movie in elementary and secondary schools, pupils could realize topographic feature of the moon surface and observe details of objects. It is suggested that hi-vision movie as a teaching media is more effective to shows natural matters and phenomenon.
