在中学地理教学中,区时计算是一个难点,也是高考备考复习中要求学生必须掌握好的一类知识。许多学生感到难掌握,有些学生碰到这类问题干脆放弃。 为解决这个教学难题,在多年的教学研究中,我设计了两套图解法,取代了以前教材教法中画数轴的方式,避免了记忆公式。通过实践检验,用图解法,学生既能准确掌握知识又能做到解题准确无误。现将图解法介绍如下: 关于区时的计算问题,基本上可以归纳为两类。 第一类:已知某一地
In high school geography teaching, calculating the time zone is a difficult point, and it is also a class of knowledge that students must master in the college entrance exam preparation review. Many students find it difficult to master, and some students simply give up on such problems. In order to solve this teaching problem, in the years of teaching research, I designed two sets of graphic methods, which replaced the previous method of teaching medium and large numbers of Chinese painting and avoided the memory formula. Through the practice test, with the graphic method, students can accurately grasp the knowledge and solve the problem accurately. The graphical method is now described as follows: The calculation of the time zone can basically be classified into two types. The first type: Known place
