选择性必修三Unit 5 Learning from nature
Nature in Architecture教学设计
课型 Reading
主题语境 人与自然--感恩自然,尊重自然,学习自然
内容分析 本版块呈现了一篇说明文,使用总分总的结构介绍自然给予人类在建筑方面的灵感。通过分析三个建筑物的目的、灵感来源、结构与优势,表达了人要尊重自然,与自然和谐相处,充分利用自然。进一步提高学生的语言能力和思维品质。
教学目标
1.梳理文本信息,准确把握各部分主旨大意,理清文章结果,了解说明文文体。
2.正确认识人与自然的关系,使用 PISA模式了解三个建筑物的设计目的、灵感来源、结构特点、优势,并能学以致用。
3.基于课文内容,对其进行内化,深入思考人与自然的关系,并且能恰当输出本堂课所学内容。
教学重点
①学生能够识别文体特点并且理解篇章结构
②学习理解三个建筑物建造的目的、灵感、结构与特点,能够运用 PISA模式去了解建筑物。
教学难点
①学生能够对三个建筑物进行复述并且能够针对建筑物的结构画出效果图
②深化学生以自然为核心的概念,实现认知思维上由人为核心转变为以自然为核心。
教学策略 理解-感悟-模仿-表达
教学过程
Procedures Teacher’s activity Students’ activities Purpose
Step 1:Lead-in (4 minutes) 1. T asks a question. 2. T shows a video to answer the question and lead to a word “biomimicry” 3.T lists some other examples, which have been applied into architecture to raise the title “Nature in architecture” 1. Ss appreciate the video and answer the question using the words in the video 2.Ss imagine how the familiar things in daily life can be applied. 1. 借助学生熟悉的动车一图,引出“为什么动车速度快? ”引出人类设计时从自然中寻找灵感,引起学生兴趣。 2. 通过猜测三张图是如何被运用到建筑中,引出自然是建筑的核心,从而引出标题
Step 2: Predict (2 minutes) T guides Ss to watch the three pictures in the book and think about two questions. “How much do you know about them “How could you associate them with architecture ” Ss activate their minds and say something about the things in pictures. The second question is more difficult, so they will hold it for a while 与文章相联系,初步认识三幅图片,分别是 “莲花、蚁穴、海藻”,与原有认知相关联,形成新的认识。(感知与注意)
Step3: Fast-reading(3 minutes) 1. T presents the general idea of each part. 2. T asks the genre of the passage based on the structure. 1. Ss read the passage quickly and match the main idea of each part. 2. Ss find out the genre of the passage, which includes three parts. 通过速读文章,获取文章段落大意,为下文的细读做铺垫(获取与梳理)
Step4: Careful-reading Read para.1 for What (2 minutes) T guides Ss to read Para.1 for attitude and later invites them to share. Ss read Para.1 for attitude and share their understandings. “What is the common attitude people hold towards nature ” 通过问题链,引导学生关注大众对于自然的态度,并概括出作者的观点态度。 (获取与梳理) (概括与整合)
Step5: Careful-reading Read para.2 for How(3 minutes) 1. T guides Ss to read Para. 2 to find “How does nature give inspirations ” 2. T shows the two pictures in Para.2 and guides Ss to conclude that “we learn from nature in various aspects” 1. Ss read Para.2 to find the answers. 2.Ss became a detective to find out the differences and diversity. 通过问题链,引导学生梳理和整合人类向自然界学习的原因和方式。(获取与梳理)(概括与整合)
Step6: Careful-reading Read para.3 For detail (5minutes) 1. T asks Ss to read for details to answer the following four questions. 2. T guides Ss to draw a mind map of the structure. 3.T concludes the PISA format of analyzing a building. 4. T asks Ss to use some adjective to describe the building. 5. T asks students to retell the building based on the information 1. Ss read the para. And answer the questions in chart. 2. Ss retell the building based on the information. 3.Ss use some adjective to describe the building, such as artistic, sustainable 1. 让学生对该建筑有初步认识 2. 学 生 能 够 利 用PISA 模式进行赏析建筑物,为后面活动打基础 3. 用形容词对建筑进行概括,使得学生意识到建筑物的独特之处与价值。(概括与整合)(描述与阐释)
Step7: Careful-reading Read para.4.5 for detail (10minutes) 1. T divides students in group work, describe, retell. 2.T invites different groups to appreciate the building, draw the structure, and write down the points related . 3. T invites other Ss from groups to retell and comment 1. Group 1-4 focus on the second building. Group5-8 focus on the third one. Ss work ingroups to explore the following buildings with PISA format . 2.Ss from different groups present their group work on the blackboard, with one describing the PISA, one drawing the structure 3. After listening and observing carefully, Ss from other groups try to retell , comment on other students' works 通过PISA 结构,引导学生描述所学内容,依据文字和想象绘画建筑结构和原理图,积累相关语言,从而内化赏析建筑的结构化知识;学生欣赏小组活动成果后,依据黑板上简易绘画和言语,进行复述;学生对其他同学的作品或复述发表评论。(内化与运用)(描述与阐释)(批判与评价)
Step8: Careful-reading (4 minutes) 1. T asks Ss to rethink the question proposed before “How could you associate them with architecture ” 2.T guides Ss to conclude the similarities of the three buildings so as to make a conclusion for Para.6 1.Ss match the pictures based on their understanding. 2. Ss hold the idea that Nature is the core and has given us many inspirations, even the simplest organisms. So we should live in harmony with our environment 1.学生在回顾predict 环节提出的问题,起到前后呼应的作用 2. “向自然学习 ”的思想和态度贯穿整个课堂,起到深化思想,树立正确价值观的作用。(推理与论证)(批判与评价)
Step 9: Post-reading (12minutes) T gives Ss a chance to design a building by using PISA format. Ss works in groups and draw a building based on what they have learned in the class and share with others. 输出环节需要与整堂课相呼应。重点强化使用 PISA 模式去分析赏析并且创造出属于自己的建筑物。(内化与运用)
选择性必修三 Unit 5 Learning from nature Nature in Architecture 课后反思 一、教学目标实现了吗?总体实现。班里学生水平不一,但在教学以及课后与学生交流过程中,了解到 80%学生可以完全掌握本节课的学习目标。剩下 20%学生在第三个目标--输出环节有所欠缺。尽管如此,老师鼓励他们完成自己的创作。 二、哪些环节做得好第一部分的导入环节,通过一张图片,一个问题,一个视频相连接,引出biomimicry这个词,解释意思,使得学生了解到本节课相关话题是仿生学。第二个环节的猜测,通过书上的三幅图片,激发学生兴趣并且与原有认知相结合,为更好地理解下文做铺垫。第四部分,让学生阅读第一段,找出人大众对待自然的错误态度,并引导学生指出应该有的态度,是重要的获取与梳理环节。通过问题链,让学生能够顺利地从第二段中找出自然给人类提供的灵感,并且对比两个建筑物,总结概括出人类从自然中学习体现在方方面面。最核心部分即对第三四五段落的处理。通过问题的设置与文章的阅读,整合出 PISA结构。与此同时,通过简易绘画解释结构,形成网络化认知,为下文的两个建筑物的分析做铺垫。本环节特别重视学生对信息的整合和概括能力。对待接下来两个任务的处理,即利用小组合作方式,利用文字和绘图形式,让学生积累相关语言,从而内化赏析建筑物结构知识。本环节需要特别强调的是学生需要对其他同学的作品进行评价与复述,这一步是内化与运用的关键。接下来就是对三个建筑物的对比,与第二个环节的问题相呼应,从而总结出最后一段 conclusion,再次强调对待自然的态度应该是充分利用自然、尊重自然。有效课堂的目标之一是学有所用,在最后的输出环节,引导学生利用 PISA模式以及从 shape, structure,fun_ction三方面考虑去设计一个建筑物,并且向全班展示。 三、哪些环节还有待改进首先是时间分配问题。前面两个段落用时过长,导致最后的输出环节时间较为紧张。其次在小组合作环节,未能照顾到所有学生的参与性,未能及时照顾到且鼓励不积极的学生或水平较弱的学生。
