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

首先，首席研究员从计算机在教育中的使用报告中证明了互联网在地球科学和天文学教育中更有效。其次，我们开发了一种在计算机上绘制三维地形图和地质图的新方法，并报告了这些教学效果。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，并将其上传到网络流媒体服务器上，并向学校开放。学校老师指出，他们学校的电脑上的电影流不太顺畅。这是由于硬件不足，如旧的机器或网速慢，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，我们新开发了天文图像通过望远镜的互联网中继系统，并设有互动通信子系统（电视会议）。在运用该系统的教学实践中，学生们认识到了太阳、金星等天体的特征和活动。此外，他们对与学校的互动交流也留下了深刻的印象。特别关注互联网上的这种互动交流是很重要的。在快速的互联网上，它会更容易，更顺畅。最后，作为互联网转播高清图像（1280x720像素大小）的初步工作，我们通过望远镜制作了月球图像的高清电影。通过在中小学使用高清电影的一些练习，学生可以了解月球表面的地形特征，并观察物体的细节。认为高清电影作为一种教学媒介，能更有效地展现自然事物和现象。

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.
