说课
本节课以歌曲导入新知,歌曲中两只自由欢快的小鸟把学生一下子引领到一个干净、优美的自然环境中。教师通过与学生一系列的对话互动,逐步引出本课话题:城市环境问题。接着,通过一组城市图片,让学生展开对城市A的讨论,让学生通过观察来描述干净、整洁的城市A。当学生们正沉浸在美的感受中时,一组不协调的城市B照片适时展现出来,与之前的城市A形成鲜明对比,让学生从感官上对dirty和messy产生联想。学生从学过的句型I can see … 开始探讨,在老师的引导下逐渐转用新句型 … make(s) … dirty/messy进行讨论,分别谈论了河道、街道和空气的污染源。
在课文学习部分,教师将这篇对话分成了两个部分。第一部分,先要求学生带着两个简单任务观看课文视频,旨在对课文第一部分有个初步印象。然后,让学生自读课文,对课文作进一步了解,这次学生可以找出该部分的中心句What makes our city dirty? ,并在文中逐一找出答案。在学生完全解读文本的基础上,可以让学生操练教材第60页上的Ask and answer,该环节巩固了第一部分出现的句型Is the … clean?、What makes … dirty?。课文第二部分是先用听力练习的形式呈现的,让学生带着What can we do to keep our city clean?的疑问听该部分,教师通过PPT呈现句型、图片及关键性动词put, walk, move, plant,让学生能将单词组词,让学生观察图片和所给的提示单词,进行独立思考并找到问题的多种答案,培养学生的语言组织能力和自主学习的能力。然后通过教材第60页上的练习Think and write,巩固这部分内容。分段学习完课文后,让学生通过不同形式的读来完整解读课文,教师在这个过程中纠正和规范语音语调,指导学生朗读。
在语言输出部分,设计了复述课文和制作海报的环节。制作海报是学生喜爱的活动,通过这个环节,即巩固操练新授内容,又联系了生活实际,让他们意识到环境卫生的重要性,要从身边做起,创造美好的生活环境。
本节课的几个主要关注点:
l 关注学生对课文的整体感知和细节信息的获取
l 关注学生的朗读,注重指导
l 关注学生的合作性学习
l 关注学生的阅读习惯,指导学生找关键词、句,根据上下文的意思猜出生词的意思
