在信息化背景下,网络的资源越来越丰富,可是怎样找到这些优质资源并开发为地理课程?对教学任务重又想开发优质地理课程的教师而言,一直都是难题。地理实验种类较多,有些实验受教室环境的限制,无法开展实验活动,有些实验观察的周期比较长,一节课的时间往往是不够的;有些实验工具需要特别制作,教师想做却无法制作出来;有些实验需要场地较大,教室的空间有限无法开展。然而,借助现代教育技术,将这些无法开展的地理实 Under the background of informationization, the resources of the network are getting more and more abundant. However, how to find these high-quality resources and develop them as geography courses? It is always a problem for teachers who want to develop high-quality geography courses again. There are many types of geography experiments. Some of the experiments are limited by the classroom environment and can not carry out experimental activities. Some experiment observation cycles are long and one class lesson is often not enough time.
