高中地理教材,或明或暗地一直在向学生阐明和强调一条基本的地理思想——“地理环境具有明显的区域差异,人类的生产活动应因地制宜”。必修3教材以各种各样的案例为载体,结合实际,将该思想更系统全面地呈现出来的,《流域的综合开发──以美国田纳西河流域为例》便是这样的一节内容。在教学设计时,教师既要指导学生充分了解和分析田纳西河流域的开发背景和综合治理的措施,又要引导学生学会研究其他流域的综合开发。
High school geography textbooks, either explicitly or implicitly, have been to clarify and emphasize to students a basic geographical idea - “there are obvious geographical differences in geographical environment, and human production activities should be tailored to local conditions.” Compulsory 3 textbooks with a variety of cases as a carrier, combined with reality, the idea presented more systematically and comprehensively, “Integrated Development of Watershed ─ ─ Tennessee Valley in the United States as an example” is one such content. In teaching design, teachers should not only guide students to fully understand and analyze the development background and comprehensive management measures of the Tennessee River Basin, but also guide students to learn about the comprehensive development of other watersheds.
