项目摘要

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.

首先，首席调查员从计算机在地球科学和天文学教育中的使用报告中证明了互联网传播在地球科学和天文学教育中更有效。接下来，我们开发了一种在计算机上绘制三维地形图和地质图的过程，并报告了这些教育效果。作为一项主要活动，我们制作了许多可用于中学(初中和高中)地球科学和天文学习的有效网络电影(640x480像素大小)，这些电影已上载到网络流媒体服务器上，并已向学校开放。学校教师指出，他们学校的电脑上的电影播放不太顺畅。这是由于这些学校硬件不足，如旧机器或网络速度慢造成的。这一问题的可能解决方案可能取决于未来教育方面的资金支持。作为另一项主要活动，我们新开发了天文图像互联网转播系统，其中包括一个互动交流子系统(电视会议)。通过一些使用该系统的教育实践，学生们已经认识到了天文物体的特征和活动，如太阳和金星转播。此外，他们对与大学的互动交流也表现出了很大的印象。重要的是要特别关注互联网上的这种互动交流。最后，作为高清图像(1280x720像素大小)互联网转播的初步尝试，我们用望远镜制作了高清月球图像的高清电影。通过在中小学生中使用高清电影的一些练习，小学生可以了解月球表面的地形特征，观察物体的细节。认为高清电影作为一种教学媒体，更能有效地展现自然事物和现象。
