项目摘要

We made the telecommunication network with PHS. Between Osaka Prefectural Education Center and elementary schools of research cooperators, a remote lesson of physical region, three remote lessons of chemical regions and two remote lessons of biological regions were done. Network softwear is NetMeeting of Microsoft company. Pictures were taken by digital video camera into personal computer(PC) and sounds and voices were also taken by microphone into PC. These pictures and sounds were provided to schools with PHS. Because the maximum speed of telecommunication is 64 kbs, frames of pictures are one or two. Even if the condition of telecommunication is good, fast phenomena cannnot be expressed. Moving pictures are sent as files beforehand. Their pictures and files were magnified by projector, for all children of a class could see them. The content of lesson in a physical region is "function of electric current". We paid attention to heat of electric current. About heat and light of this function, we did an experiment of electric bulb. We applied an electric voltage to carbon filament in liquid nitrogen. With this experiment, we explained an electric bulb. In chemical region, we did lessons of solution of materials, paticularly, large crystal growth from solution. In biological region, we taught children the process of which butterfly grows up from an egg and bodies of insects. Children learned foods, the way of eating, paticularly. Mouths of insects were observed with scanning electron microscope. Investigation of questionnaire was very good. The percent of which children hope to take these remote lessons is 96.7%. The percent of which children understood these contents of remote lessons is 81.5%. Children were interested in science by these remote lessons, in spite of difficult contents of these lessons.

我们用小灵通建立了电信网络。大阪府教育中心和合作研究小学之间进行了物理领域的远程课程、化学领域的远程课程的三堂和生物领域的远程课程的两堂。网络软件是微软公司的NetMeeting。照片由数码摄像机拍摄到个人电脑(PC)中，声音和声音也由麦克风拍摄到PC中。这些图片和声音被提供给拥有 PHS 的学校。由于电信的最高速率为64kbs，所以图像帧为一帧或两帧。即使电信条件再好，也无法表达快速的现象。动态图像预先作为文件发送。他们的照片和文件被投影仪放大，班上所有的孩子都可以看到它们。物理区域的课程内容是“电流的函数”。我们关注电流的热量。关于热和光这个功能，我们做了一个电灯泡的实验。我们对液氮中的碳丝施加电压。通过这个实验，我们解释了一个电灯泡。在化学领域，我们学习了材料溶液的课程，特别是从溶液中生长大晶体的课程。在生物区，我们教孩子们蝴蝶从卵和昆虫尸体中成长的过程。孩子们学习食物，特别是饮食方式。用扫描电子显微镜观察昆虫的嘴。问卷调查的效果非常好。孩子们希望参加远程课程的比例为96.7%。孩子们理解远程课程内容的比例为81.5%。尽管这些课程的内容很困难，但孩子们通过这些远程课程对科学产生了兴趣。
