摘要
本文主要对《地球概论》中的教学难点“天球坐标系” ,结合教学实践与有关教材进行深入的分析和研究 ,提出突破这一教学难点的 3个关键 :找准衔接点 ;建立易于掌握的坐标系模式 ;清楚地给出基本点和大圆的系统。
In this article,“celestial coordinate system”, the difficult point in the teaching of the Conspectus of the Earth, is analysed and studied and three key points are proposed: finding the joint point, establishing an coordinate system mode that can be accepted easily and giving out the basic dots & great circle system very distinctly.
