教学的基本思路 自然课中教学生认识六类动物,前五类是脊椎动物,最后一类是昆虫。两栖动物的认识居五类脊椎动物之末,因此有条件把这一课的教学过程设计成为类似科学家发现新物种的过程,让学生处在探索的情境下学习。基本思路: ● “青蛙是一种什么样的动物?” ● “什么动物和青蛙相似?”找青蛙的同类——蟾蜍。 “这两种动物有什么共同点?” ● “这两种动物同属于哪一类动物?”运用已有的知识分析、比较,与前四类动物都不同。
The basic idea of teaching Natural class teaching students to recognize six kinds of animals, the first five are vertebrates, the last one is insects. Amphibians recognize the end of five vertebrates, so the conditionally teaching process of this lesson can be designed to be similar to the process of scientists discovering new species, allowing students to learn in the context of exploration. The basic idea is: ● “What kind of animal is a frog?” ● “What animal resembles a frog?” Find the same kind of frog - Toad. “What do the two animals have in common?” ● “Which animals are both animals of the same type?” Using existing knowledge to analyze, compare and contrast with the first four animals.
