《鸟》一课,教材的设计思路是:认识鸟的外形特点→联系生活环境认识鸟的脚和喙→通过与其它动物比较找鸟的共同特征→鸟的知识应用。第一次试教,我发现,引导学生联系鸟 的生活环境认识鸟的脚和喙时,学生 思维极其活跃,不但联系每小组鸽 “Bird” lesson, the teaching material is designed to: recognize the shape of the bird → contact with the living environment to know the feet and beaks of birds → find the common features of birds by comparing with other animals → application of bird knowledge. For the first time, I found that when students were guided to contact the bird's living environment to know birds' beaks and beaks, students were extremely active in thinking that they should not only contact every small group of pigeons
