地理教学中有关地壳的部分能够直观展示的只有一些矿物质和地层的图片和视频,因此显得枯燥。但是教师展示两幅图片让学生猜测图片分别描述的成语引入了新课独具匠心。又利用拟人化的小故事贯穿整堂课,说明三大类岩石的分类及成因,三大类岩石的相互转化,并结合示意图说明地壳内部物质循环过程及地壳物质组成,使教充满了趣味性,学习过程变得更轻松。
The parts of the geography teaching about the crust can be visualized with pictures and videos of some minerals and formations and thus appear dull. However, the teacher showed two pictures to help students guess that the idioms described in the pictures respectively introduced the new lesson. The anthropomorphic stories are used throughout the entire lesson to explain the classification and genesis of the three major types of rocks, the mutual transformation of the three major types of rocks, and a schematic diagram illustrating the material circulation within the crust and the crustal material composition to enrich teaching , The learning process becomes easier.
