教学设计课题：人教2019课标版选择性必修第二册Unit 1 Science and ScientistsReading and Thinking: John Snow Defeats “King Cholera”(Period 1)主题语境：人与社会——科学与技术语篇类型：记叙文（事件发展过程）授课时长：45分钟授课对象：授课教师：指导教师：授课时间：文本分析本文是一篇按照时间顺序记述事件发展过程的叙事性文本，时间线索是明线，而科学研究的步骤是文章叙述的暗线。
文章的第一段介绍了研究的背景。
第二段为科学研究的第一个阶段，即问题的提出(Find a problem)：关于霍乱的病源，当时有两种观点，斯诺需要通过研究找到真正的病源。
第三段讲述了斯诺所采用的研究过程：收集数据、分析结果、找到进一步佐证，最终得岀结论(Collect data —Analyse the results— Find supporting evidence—Draw a conclusion)。
他的研究成果和研究方法对今天预防霍乱具有现实意义。
学情分析本课的教学对象是高二学生，学生在语言知识方面有一定的基础，他们的认知能力有了进一步的发展，也具备一定的获取信息的能力，但对科学研究的基本步骤比较陌生，用英语进行思维和表达的能力也有待加强。
教学目标经过本课的学习，学生能够：1. 阅读约翰·斯诺研究霍乱病源的记叙文，把握文本的时间线索，并结合斯诺的研究过程梳理科学研究的基本步骤。
2. 理解图表中的信息，读懂符号和图注的意义，并结合文字信息深入理解文章内容。
3. 通过斯诺的事迹理解质疑精神的意义，学会批判性地思考。
教学重难点引导学生研读语篇、梳理信息、分析结构，了解科学研究的基本步骤；理解质疑精神在科学研究中的重要作用，思考科学研究对人类的影响。
