高中地理“地球运动”的知识,要求初学者具备较高的空间想象能力。摆在教师面前的难题是:高一学生只具备初中的平面几何知识,立体几何知识只有在高二才接触到。例如关于“由于黄赤交角的存在导致太阳直射点的南北移动”的知识,在平时的听课过程中,有些教师在平时的教学中采用经纬仪(或地球仪)演示的方法进行讲授,学生的确能够获得直观的印 High school geography “earth movement ” knowledge, require beginners have a high spatial imagination. In front of teachers is the problem: high school students only have a plane geometry knowledge of junior high school, three-dimensional geometry knowledge only in the second year of exposure. For example, regarding the knowledge that “the north-south movement of the sun’s direct point is caused by the existence of the yellow-red crossing angle”, some teachers use the theodolite (or globe) demonstration method to teach in normal teaching.
