北回归线以北的地区,任可一天中正午太阳高度最大,但不能为90°。学生对比是不容易接受的。如果画成下图,学生则认为正午太阳高度角一定为 60°,结果适得其反。我在教学实践中曾对这类问题从另一角度讲西招过, 砚招衬厅透视、分析,学生容易理解,三女果显著盆笔者称之为“变方位分析法”。 In the area north of the Tropic of Capricorn, the sun may be at its highest altitude at noon of the day, but it cannot be 90°. Student comparison is not easy to accept. If they are drawn as the following figure, the students think that the height of the sun at noon must be 60°. The result is counterproductive. In my teaching practice, I once asked the West about this type of problem from another perspective. I look forward to the analysis and analysis of the lining room. The students are easy to understand, and the three women’s significant basins are referred to by the writer as “variant orientation analysis.”
