两栖动物——青蛙教学片断设计

Amphibian——Frog Teaching Fragment Design

本文以两栖动物——青蛙为基础,利用两栖动物的特征形成课堂主线,通过教师讲解,提出问题,并组织学生进行自主学习和总结,来培养学生的思考能力及分析问题能力,树立生物形态、结构与功能相统一的生物学观点,同时充分认识保护生物多样性的意义。

Based on amphibian-frog, this paper uses the characteristics of amphibians to form the main line of the classroom. Through teachers' explanations, questions are raised, and students are organized to study and summarize independently, so as to cultivate students' thinking ability and problem analysis ability, establish a biological viewpoint that combines biology form, structure and function, and fully understand the significance of biodiversity protection.
