Unit 1 Science and Scientists Reading and Thinking 教学设计-2025-2026学年高中英语人教版选择性必修第二册

该高中英语教学设计围绕John Snow战胜霍乱的文本，聚焦科学研究步骤与科学精神。导入采用游戏化设计，结合霍乱视频和研究路线图，以任务卡、小组探究为支架，衔接词汇学习与文本分析。 亮点是“语言+思维”双目标融合，通过地图分析任务（如解读死亡数据推断病因）培养思维品质，小组合作找科学步骤语句提升语言能力，分层作业兼顾基础与拓展。落实词汇与文本解读，渗透科学探究方法，助力教师高效教学，促进学生逻辑思维与自主学习能力发展。

附件： 教学设计 课程基本信息 课题 Reading and Thinking 课型 新授课 学科 英语 年级 高二 学段 高中 版本章节 人教版选必二一单元 教学目标 By the end of this section, students will be able to: 1. learn some new words, such as cholera, infection, subscribe and so on; 1. read about how John Snow defeats “king cholera”; 1. know the stages of scientific research and how to describe scientific methodology; 1. to have a better understanding of scientific spirit. 教学重难点 Important point: Guide students to understand the important role of questioning spirit in scientific research and think about the impact of scientific research on human beings. Difficult point: Guide students to study the text, sort out the information and analyze the structure. 学情分析 1.知识基础：高二学生已掌握基础英语词汇和语法，对"科学"话题有初步认知，但专业术语（如cholera, epidemic, investigation）积累不足；具备简单阅读理解能力，能梳理基本叙事逻辑，但分析文本结构、提炼科学思维的能力有待提升。 ​2.认知特点：高中生好奇心强，对"科学家故事"类文本兴趣浓厚，擅长小组合作探究，但抽象思维仍需具象引导，对科学研究方法的逻辑链条理解存在困难。 ​3.学习痛点：易忽视文本中科学探究的步骤细节，难以将叙事内容与科学思维方法关联，书面表达中逻辑衔接词使用不够规范。 教学准备 1. 教师准备：制作多媒体课件（包含霍乱历史背景视频、约翰·斯诺研究路线图）；准备本课的学案、小组探究任务卡；设计课堂检测习题。 2. 学生准备：预习文本中的新词汇（借助词典标注音标和释义）；查阅霍乱相关背景知识；准备笔记本和红笔。 教学过程 教学任务 教学内容 设计意图 创新设计（含AI应用） Let students get ready to play a game and learn about the rules of the game. Then show a video about the cholera to make students be familiar with this kind of disease. Lead-in Play a game with ss. There are two persons: king cholera and John Snow. Seeing so many deaths in London, John Snow wanted to destroy the cholera. But how can he start? Today we will help John Snow to defeat “king cholera”. Arouse students’ interest and make students have a basic understanding of cholera. 将科学家对抗疾病的过程转换成游戏的思路，学生可以在阅读和完成任务的过程中感受到玩家的体验感，并与科学家一起感受到打败疾病的成就感。 Let students have a prediction and read the text quickly to put the stages of scientific research in the correct order. Prediction Task 1: Put the stages of scientific research in the correct order. 1.Find a problem 2.ask a question 3.think of a method 4.collect data 5.analyze the results 6.find the supporting evidence 7.draw a conclusion Now John Snow is more clearly about how to conduct a scientific research. But as a Chinese saying goes, know the enemy and know yourself. Then let’s help John Snow to know more about him and his enemy. Help students get familiar with the 7 stages of scientific research. Students read para. 1 and find the information. Students read para.2 and choose the correct theory. Students read para. 3 and answer the following questions. Scanning Task 1: Read para. 1 and fill the blanks. John Snow: One of the most feared diseases… What cause it? Maybe we should get inspiration from other’s opinions. Task 2: Read para.2 and choose the correct theory. Two theories: Teacher helps ss to translate some important words: infection; subscribe to.. Task 3: John have got some clues from a map. Now read the map and answer following questions: 1.What does “—” mean? How about PH? 2.Which house numbers had more than four deaths in Broad Street? 3.Which house numbers had no deaths in Broad Street? 4.Why some households (20, 21, 8 and 9) had no death? 5.What’s the similarity among the houses in Broad Street that had multiple death? 6. What’s you deduction/assumption? Guide students to study the text, sort out the information and analyze the structure. Work in groups and find the sentences corresponding to the 7 stages of scientific research. Read para. 4 &5 and answer questions. Careful Reading Work in pairs. Read para. 2 &3, find the sentences corresponding to the 7 steps to complete the guidebook. Then, what’s the truth? Watch the video and answer questions. 1.What caused the outbreak of cholera? 2.Was cholera destroyed completely? 3.What contribution did John Snow make? To make students have a better understanding of detailed information of the text. Students discuss in groups to talk about the following question. Discussion What made John Snow defeat king cholera? e.g. qualities, mindset… Critical thinking; innovative spirit; Scientific methods; prudent attitude… It was …that made him defeat cholera, since… To arouse students’ more deep thinking about this topic. 作业设计 1. 背诵文本中的核心词汇、短语及关键句型（如"John Snow suspected that the second theory was correct."），下次课听写。 2. 用5-8句话复述约翰·斯诺战胜霍乱的过程，要求使用逻辑衔接词。 提升作业（选做） 查阅一位自己喜爱的科学家的故事，用英语写一篇100词左右的短文，分析其科学探究方法。 板书设计/课堂小结 Unit 1 John Snow Defeats "King Cholera" 一、Core Vocabulary & Phrases epidemic investigate conclude link...to... figure out take measures 二、Scientific Research Steps 1. Raise a question (What causes cholera?) 2. Collect evidence (survey cases) 3. Analyze data (map the deaths) 4. Draw a conclusion (polluted water is the cause) 5. Verify & Take action (remove the pump handle) 三、Scientist's Qualities careful, determined, creative, practical… 教学反思 1. 教学环节逻辑清晰，从"导入→感知→探究→巩固→总结"层层递进，符合学生认知规律； 2. 聚焦"语言+思维"双重目标，通过小组合作、任务驱动等活动，有效调动学生参与度，实现了文本解读与科学思维的有机结合； 3. 作业设计分层明确，兼顾基础与提升，能满足不同学生的学习需求。 不足与改进方向 1. 时间分配略显紧张，部分小组在深度探究环节未能充分展开讨论，后续可适当压缩导入或巩固环节时间，给探究活动留出更多空间； 2. 背景知识铺垫不足，部分学生对霍乱的历史影响理解不深，可在预习阶段布置简单的背景阅读任务，或在课件中补充更多直观图片资料。 学科网（北京）股份有限公司 $
