Development of digital teaching material for "Digital earth science" in connection with environmental monitor and providing in- service training to teachers.

本文是为创建“数字地球科学”新学科而进行的教材建设研究。1.以环境监测器为课题，以大坂等城市地区特有的现象为教材，对“热岛”和“跟踪光和空气污染指数的星星观测”进行了研究。（1）“热岛”观测在大坂府内的14个点，每10公里左右设置观测点，通过数据记录仪每十分钟连续观测一次温度和湿度。阐明了最低气温月平均值的大坂中心区与郊区在春季和秋季增长趋势上的差异，以及拍岛控制白天海风的影响。此外，还在网上公布了实时气象数据（www.diges.net）。(2)为了使“星星观测”的研究成为学生们的一种容易的方法，设计了用计算机测量从用数码相机等电子设备拍摄的天文照片到夜空的亮度的方法。实际上进行了天文观测，并且能够获得城市部分、郊区和山谷部分之间的差异。2.这些观测结果被用于教师的在职培训，假设“现实的热岛”和“天体图像处理”是一个问题。3.开发了新的数字化教材，如利用互联网上的各种天气信息，介绍当地天气的时间序列变化，并将近年来的一次自然灾害作为数据库。

The research on the teaching material development was done for the establishment of a new subject "Digital earth science ". 1. To assume an environmental monitor to be a subject, and to make a peculiar phenomenon to the city region in Osaka etc. a teaching material, "Heat island" and "Star observation for the index of tracking light and air pollution" were investigated. (1)The observation of "Heat island" continuously observed every ten minutes of the temperature and humidity by the data logger by setting up the observation point in 14 points in Osaka Prefecture every all sides about 10km. It was clarified to the difference between the central area of Osaka of the monthly mean value of the minimum temperature and suburbs in seeing the tendency which grew in spring and autumn, and that there was an effect of the sea breeze of the beat island control daytime. Moreover, real-time meteorological data was published on the web (http://www.diges.net). (2) To make the investigation of "Star observation" a approach of the student at the school easily, the method of measuring brightness from the astronomical photograph which had been taken with electronic devices such as digital cameras to the night sky with the computer was designed. The astronomical observation was actually executed, and the difference among the city part, suburbs, and the ravine part was able to be obtained. 2. These observation results were used in in-service training of teachers which assumed "Realities of the heat island" and "Heavenly body image processing" to be a problem. 3. New digital teaching materials such as the time series changes concerning local weather in which various weather information in the Internet was used and making of a natural disaster in recent years a data base were developed.
