高中英语必修五《unit1 Great Scientists》示范说课稿
《unit1 Great Scientists》说课稿各位评委老师，上午好！我是号考生，我今天说课的题目是《unit1 Great Scientists》。
我主要从教材分析、教学方法与策略、教学过程、板书设计等几个步骤向大家详细地讲解我对这节课的安排。
一．说教材1. 教材内容本节课是人教课标版必修5第一单元的第一课时的Reading部分，是该单元的主要内容，它介绍了英国著名医生John Snow是如何通过考察、分析、探究的科学方法，发现并控制“霍乱”这种传染病的。
通过阅读课文，使学生感悟科学家的周密观察、勇于探索、认真分析的科学精神，使学生了解科学方发现的全过程具有其科学的严密性。
2. 教学目标结合单元教学要求和本课特点，充分考虑学生的年龄特点、认知水平，遂将本课的教学目标确定为：知识目标1) Get students to learn the useful new words and expressions in this part.2) Let students learn about some great scientists and their contribution.3) Have students read the passage and know about John Snow and how he defeated “King Cholera”.能力目标1) Develop students’ reading ability and let them learn different reading skills.2) Enable students to talk about great scientists and tell their stories.情感目标1) Let students learn from great scientists, stimulate their love and respect for them and develop their moral qualities.2) Develop student’s sense of cooperative learning.3. 教学重点因为本组教材的重点了解项目是“John Snow 破解King Cholera难题”，所以确定本课的教学重点是：1) Let students learn about some great scientists and their contributions.2) Get students to read the passage and know about John Snow and how he defeated “ King Cholera”.3) Have students learn different reading skills.4．教学难点考虑到学生拓展阅读能力，语言输出能力等方面还需进一步努力，所以将本课的教学难点确定为：1) Develop students’ reading ability.2) Enable students to talk about great scientists and tell their stories.3) Let students learn how to organize scientific research.二．说教法和学法1. 教学方法引导学生独立思考，合作学习，进行师生、生生互动的“任务型”教学，设计了许多易于操作的任务型活动。

三、本单元教学建议
热身（Warming up）部分在学生课前预习的基础上，教 师可利用图片资料引入，也可以让学生讲述某位科学家的 故事或成就让其他学生来猜测，但讲述内容不宜过长。
读前（Pre-reading）部分建议呈现有关SARS和AIDS宣传 图片或视频资料，引导学生关注疾病与健康，然后再引出 cholera。可以分若干个讨论小组讨论如何进行科学研究， 让学生了解科学观点的形成过程。
.
三、本单元教学建议
语言学习（Learning about language）部分Exercise 1是用所 给词的正确形式填空。教师应确定学生了解这些词的意思 和用法。Exercise 2是一个拓展练习，要求学生掌握make+ 名词，在意义上等于这个名词的动词形式，例如：make a speech=speak。Exercise 3进一步训练动词make的用法。教 师 还 可 以 鼓 励 学 生 回 忆 更 多 的 有 关 于 make 的 用 法 。 Discovering useful structures是语法知识教学，教师可引导 学生在Reading中找到更多过去分词作定语和表语的用法。 Exercise 1、2&3帮助学生感知过去分词作定语和表语，并 逐步过渡到巩固和运用这种语言现象。
.
