《高中地理》自然地理部分,教学难度较大。近年来我们运用分解法来处理教材,有的顺序排列,文字分解;有的模拟演示,简图分解;有的归纳比较,列表分解。通过不同教材不同方法的运用,把教材中某些抽象、复杂而难懂的概念,分解为多个循环渐进,有机联系的小点,既帮助学生在学习过程中化难为易,又开发、诱导其创造思维能力。在《高中地理》第五章“地球上的生物、土壤和自然带”的讲授过程中,我们依据教材内容,采用归纳比较、列表分解的方法,将知识点连成知识线。进而织成知识网,从各个方面揭示其相互间的 The physical geography of High School Geography makes teaching more difficult. In recent years, we have used the decomposition method to deal with teaching materials, some of them are arranged in order, and the text is decomposed; some simulations are shown, and the diagrams are decomposed; some are summarized and compared, and the list is decomposed. Through the use of different methods of teaching materials, some of the abstract, complex and difficult concepts in the teaching materials are decomposed into multiple, gradual, and organically connected points that not only help students to learn in the learning process, but also develop and induce them. It creates thinking ability. In the course of the fifth chapter of “geography of high schools” and “biology, soil, and natural belts on the earth,” we used the methods of induction, comparison, and list decomposition to connect knowledge points into knowledge lines. And weaving into a knowledge network that reveals each other’s
