Unit 4 Scientists Who Changed the World Extended reading The Value of Science 课件-2025-2026学年高中英语译林版（2020）必修第三册

该高中英语课件围绕《The Value of Science》展开，核心讲解科学的三个价值（知识应用、智力享受、怀疑自由）及科学家的责任。课堂从费曼战前战后对科学的困惑切入，通过问题链搭建“困惑-价值-责任”的学习支架，帮助学生梳理逻辑脉络。 其亮点在于融合跨文化元素（孟子“尽信书不如无书”、亚里士多德名言）与科学思维（怀疑精神、进步循环），以“苹果树”类比（树=科学，苹果=价值，爬树=自主学习）和讨论题（如AI使用、质疑老师错误）培养学生思维品质与文化意识。教学设计清晰分块，互动性强，助力学生将科学价值应用于生活学习，也为教师提供明确的教学路径与丰富活动素材。
