教学设计理念

本课时根据课标提出的六要素整合的英语学习活动观理念，关注学生学习参与的实际获得，创设与主题意义密切相关的语境，引导学生对文本主题意义的探究。依据英语学科能力要素及表现指征框架进行学习理解类，应用实践类和迁移创新类活动过程中培养学生语言理解和表达能力，推动学生对主题意义的深度学习，构建新知，发展思维。探究科学家的必备品质和科学精神的基本要素，达到学科育人，落实对学生学学科素养的培育。

文本解读

主题语境：该部分的活动主题是“写一写伟大科学家的必备素养”（Write about what makes a great scientist）,要求学生阅读钱学森和斯蒂芬.霍金的人物传记，掌握此类文章的文体结构、行文特点及语言特色，并分析他们身上体现的科学精神，最后写一篇关于伟大科学家的短文。

语篇类型：记叙文

语篇研读：

【what】前面的读思板块重点为科学家的精神和和理解质疑精神的意义，而此处的读写板块则聚焦“人物传记”。教材选取了钱学森和斯蒂芬.霍金的人物传记。

【why】人物传记记叙文通常按时间顺序展开。学生理解两篇文章的重要细节和关键问题，通过两位科学家的经历和事迹分析他们的性格特点以及他们所具备的科学精神，同时引导学生从语言和语篇结构两方面分析阅读文本，具体包括：衔接词语的使用、段落拓展方式、描述科学家品格的词汇，以及如何使用恰当的事例说明观点，为深入理解写作话题作准备。

【How】该板块要求学生写关于伟大的科学家的短文，目的引导学生分析语篇结构进而掌握文体的结构，熟悉文中标识性语言，同时合理组织语言，关注语篇的衔接和连贯，有效使用了一些衔接词语，如：however、nevertheless、 because、in general、besides、furthermore、above all等。其次，通过模仿写作，让学生熟悉文中的语言及句型，迁移运用为写作的语言及句式。

学情分析

本节课授课对象是高二普通班学生。学生英语基础个体差异较大，但是大部分学生思维活跃、英语学习热情高，模仿能力强。本节课是本单元学习的第三个课时，深入了解文本内容和文章架构。让学生在讨论新科技的利弊时表达自己对其的观点，达到学科育人，落实对学生学学科素养的培育。主要内容为研读文本后，以文章中的句式和词语为架构模板，为学生搭建如何写作的“脚手架”，使其顺利完成接下来的写作任务做好铺垫。由于本班学生的词汇量和写作能力还较为薄弱，因此在授课过程中给学生提供相关的词汇和写作的句式。

【语篇话题】活动主题是“写一写伟大科学家的必备素养”(Write about what makes a great scientist), 要求学生通过阅读钱学森和霍金的人物传记，以及约翰 ·斯诺研究霍乱病源的过程，并结合自身体验和知识积累写一篇文章，分析伟大科学家的品格和素养，阐述科学精神的内涵。

【语篇语言】人物传记是记叙文的一种形式，语言精辟简练，标识性语言明显，语篇结构清晰。大部分学生认为难度适中，能较好的理解语篇中伟大科学家的品格和素养，及其科学精神的内涵。

【语篇理解】学生已经基本具备在阅读中获取细节信息的能力，部分学生能用英语描述人物品质。但是多数学生在理解和整合知识，以及在写作框架等方面学科能力要素上需要提升。
