中学地理教学,常遇到这样的问题:教材中只提出现象未作进一步说明;学生课外提出一些与地理有关的问题,向老师请教.对这两类问题,我是这样处理的,下面举例说明:第一类问题,如:高中地理上册第二章第三节“季风”部分提到“夏季,北太平洋高压势力大大增强,…….”为什么会“大大增强”,并未作说明.习惯于用气温高低来解释气压变化的学生,一时觉得很难理解.难以理解的原因在于学生忽视了北太平洋高压是副热带高气压的一部分,属动力性高压.其势力的强弱,除主要决定于副热带高空下沉气流的强势之外,还和东西两侧的环境有一定关 In high school geography teaching, we often encounter such problems: in the teaching materials, only the phenomenon is not explained further; the students put forward some geography-related problems outside the class and ask the teacher for advice. I dealt with these two types of problems as follows. : The first type of problem, such as: “The monsoon” in the third chapter of the second chapter of the Geography Book of Senior High School mentioned that “in the summer, the high pressure forces in the North Pacific have been greatly enhanced, .......” why it has “greatly enhanced” and has not been explained. Students who use air temperature to explain changes in air pressure find it difficult to understand for a time. The reason why it is difficult to understand is that students neglected that the North Pacific high pressure is part of the subtropical high pressure, and it is a dynamic high pressure. Its strength is determined by In addition to the strong subsidence of the subtropical sky, it also has a certain degree of
