A Basic Study for Developing the Science Curriculum to Consider the Conservation of Environment.

本研究调查了两所初中1991年二年级和1992年三年级的学生通过观察雾和陆地卫星图像对自然环境的认识情况，主要结果如下：（1）观察雾和通过视频观看图像的学生的比较。在前测中有很多学生对雾的认识是静态的，但在观察雾后，有很多学生对雾的认识变成了动态的，在学生通过视频观看雾的情况下，有很多学生仍然对雾的认识是静态的。(2)后测结果中对雾的印象较深，很多学生指出了雾的移动、明暗变化、消散的景象。关于雾的形象，虽然学生在前测中没有指出这些东西，但他们指出了非常奇怪、非常有趣和非常神秘的东西。(3)利用陆地卫星图像进行调查的结果表明，学生在陆地卫星图像上能很好地掌握自己生活空间周围的一些点，但对一些山谷及其汇流处把握不好，约50%的学生能在地形图上画出陆地卫星图像上的雾覆盖区。

It was investigated that how the students recognize the natural environment through observation of fog and landsat image.The students in this survey are 2nd grader in 1991, and 3rd grader in 1992 in the two lower secondary school.The main findings are as follows :(1) the comparison between the student observed the fog and the student saw the image by video. there are a lot of students to recognize statically the fog in pretest, but after observation of the fog, many students become to recognizw dynamically the fog.In case of the student to look the fog by videg-, there are a lot of students to recognize still statically the fog.(2) the strong impression regarding the fog in the results of post-test.A lot of students pointed out the moving, change of light and shade, the scene of clearing up regarding the fog. Regarding the image of the fog, ttie students pointed out to be very strange, very interesting and very mysterious though the students did not point out such things in pre-test.(3) The results of servey by using landsat image.Through the students can well grasp some spots around their living space in the landsat image, they can not grasp well some valley and their confluence.About 50%students can draw, in topographical map, the area covered with fog in the landsat image.
