极视图巧解地球自转运动难点问题的应用研究

Application Research on the Ingenious Resolution of Difficulties in Earth's Rotational Movement Using Polar

在新高考背景下,相对方位判读、时间计算和日期分布作为选择性必修内容仍是教学中的重点和难点、该教学内容抽象,大多数学生未建立地理空间思维模型,教学效率普遍偏低.文章从教学难点出发,构建地理极视图模型,并用极视图模型结合实际案例,分析和解决难点问题.该方法避免了解题套公式和死记硬背的方式,从而使问题图示化和直观化,有效地提高教学效率.

In the context of the new college entrance examination,relative orientation interpretation,time calculation,and date distribution are still key and challenging aspects in teaching,as part of op⁃tional compulsory content.The difficulty lies in the abstract nature of the teaching content.Most stu⁃dents have not developed a geospatial thinking model,leading to generally low teaching efficiency.To address these teaching difficulties,this paper presents a geographical polar view model and utilizes it to analyze and resolve challenging problems in conjunction with practical cases.This method eschews the approach of memorizing problem sets and promotes graphical and intuitive problem solving.
