教学中我们不难发现,高中地理教材中有许多潜在的知识点。它们中有的只有结论而无原因,有的只有概念而无解释。所以,教学中,教师有必要了解它们,这对于搞好教学,帮助学生学习新内容有着重要的作用。本文就此问题举几例,供参考。 (一)教材未加注解的概念①地球自转的角速度;②地球自转的线速度;③地层;④自然保护区;⑤滩涂;⑥石油输出国;⑦复种指数;⑧农业专业化;⑨农业区域化;⑩农业社会化;(11)农业集约化;(12)城市;(13)城市化;(14)环境承载量。 (二)教材未进一步解释原因的结论 1.“到了南北极点,则无线速度,也无角速度”。 2.“世界上盐度最高的海区在红海,盐度超过40‰”。 3.我国最先在浙江、广东兴建核电站。 (三)图像中教材未加说明的地理事象 1.“理想大陆自然带分布图”:①为什么亚寒带针叶林带南半球缺
In teaching, we can easily find that there are many potential knowledge points in the high school geography textbooks. Some of them have only conclusions and no reasons, while others only have concepts and no explanations. Therefore, in teaching, teachers need to understand them. This has an important role to play in teaching and helping students learn new content. This article gives a few examples of this issue for your reference. (a) Concept of unannotated textbook 1 Angular velocity of rotation of the earth; 2 Linear velocity of rotation of the earth; 3 stratum; 4 nature reserve; 5 tidal flats; 6 oil exporting countries; 7 multiple cropping index; 8 agricultural specialization; 9 agricultural region (10) Agricultural Intensivism; (12) Cities; (13) Urbanization; (14) Environmental Carrying Capacity. (B) The textbook did not further explain the reasons for the conclusion 1. “to the north and south poles, the wireless speed, there is no angular speed ”. 2. “The salinity of the world’s highest sea area in the Red Sea, salinity more than 40 ‰ ”. 3. China first built nuclear power plants in Zhejiang and Guangdong. (3) Undocumented geography in the images 1. “Ideal distribution of the natural belt in the mainland”: 1 Why is the sub-frigid forest in the southern hemisphere missing?
