一、自主学习地理教学的实施策略1.以问题为中心组织活动以问题为中心,就是在课堂教学中,根据教学目标的要求,采用分解和铺垫的方法,设计一系列层次性、趣味性、阶梯性的问题。例如在学习“排放CO2,导致温室效应”一部分内容时,可以设计以下问题:①大气中CO2含量逐年增加的重要原因是什么?②大气中CO2增多导致全球变暖会产生什么后果?③大气中CO2的增多也可能会带来哪 First, the autonomous learning strategies for the implementation of geo-teaching 1. To organize the problem-centered activities To the problem-centered, that is, in classroom teaching, according to the requirements of teaching objectives, the use of decomposition and bedding to design a series of layers, interesting, Ladder of the problem. For example, when learning part of “CO2 emission and greenhouse effect”, we can design the following questions: (1) What is the important reason why the atmospheric CO2 content increases year by year? (2) What is the consequence of global CO2 increase in the atmosphere? Atmospheric CO2 increase may also bring what
