图表是地理知识的重要表述形式,因其简明扼要,突出重点,能揭示事物的内在联系,便于理解,便于记忆。在地理总复习中应怎样发挥图表的作用呢,我在复习“地球上的水”一章时,运用过多幅图表,有的边讲边画,有的先印好,随堂发给学生,边讲边看,效果比较显著。本文选择了头绪多、内容纷繁的“水资源的利用”一节课文,运用所概括的知识网络表解进行教学,既系统全面,又重点突出,使分散的知识条理化,便于记忆,教学成果显著,参见下表:
The chart is an important form of geography knowledge, because it is concise, highlights the key, and can reveal the internal relations of things, easy to understand and easy to remember. How should we use the charts in the review of geography? When reviewing the “Water on the Earth” chapter, I used a number of charts, some of them were on the sidelines, some of them were printed first, and they were distributed to students. When you talk and watch, the effect is more significant. This article selects a section of the text “Utilization of Water Resources” that is full of many contents, and uses the summarized knowledge network to explain the teaching. It is both systematic and focused, which enables the decentralized knowledge to be organized, easy to remember, and teaching results. Significant, see the table below:
