Word Formation教学设计

主题语境：人与自我-----语言学习的规律、方法等

语言知识:

词汇知识

授课时长：一课时

学习内容分析:本课的学习内容为构词法，内容较为凌乱，琐碎。在学习《2017普通高中新课程标准》的理论背景下，我了解到所有的语言活动都需要在一定的主题语境下进行，要关注到学生的生活经验和认知水平，要选择有意义，又贴近学生生活经验的主题。为此，从self-introduction,自然过渡到selfie，和selfie stick(课堂上由教师携带)以及和智能机使用的相关话题，激发学生参与学习和体验语言的兴趣，贯穿课堂始终。让学生了解到词汇学习，不是单纯的词语记忆，也不是独立的词语操练，而是结合主题在特定语境下开展的综合性语言实践活动。在此过程中，鼓励学生学习和应用词汇，开展对语言意义和主题内涵的探究，特别是通过不同观点的呈现和讨论提高学生的鉴别和批判能力（最后呈现智能机的使用利弊，让学生进行思考）。在学习过程中，通过构词法、话题词等方式建构词组词汇语义网扩大词汇量，通过观察、比较、分类和总结等手段，概括具体语言形式的结构意义和使用规律，并形成一定的学习策略。

学情分析:我校地处城乡结合部，生源偏差，英语基础知识很不扎实，但思维活跃，乐于表达（经常用汉语）。学生来自高二年级，这次授课不是我所带班级。

教学目标:本课结束时，学生能够: 通过归纳总结分类的方式，了解英语中常见的前缀（in-，im-, un-, dis-, re-等

），后缀-tion, -ation ,ness，-ance, -ful, -ly, -y, -al 等)。学会根据词根来猜词，了解部分前缀或后缀的含义并注意有些词（如easily, valuable等）的拼写，扩大词汇量，增强英语学习的兴趣。感受并思考智能机的利弊，并适当用自己的语言表达。

教学重点：

了解部分前缀或后缀的含义并注意有些词（如easily, valuable等）的拼写，感受并思考智能机的利弊，并适当用自己的语言表达。

学习活动: Word Formation Step1 Lead-in This is the first time that I have given you an English lesson. First, let me give you a self-introduction.(板书self-introduction)（This is not the class I teach and the students are ordinary ones.）

My family name is Cao,and you can call me Mrs. Cao.

I ‘m very glad to be here with you today. OK,now ,let’s get down to

business. Now，can you tell me “What is this?”. (“自拍杆”). Yes, we call it a selfie stick. (板书：selfie stick) Many people like to take a selfie, or a photo of themselves and share it with their friends,relatives or colleagues by posting it on Wechat, QQ, instagram etc.，including，the great man “Obama”

(PPT展示奥巴马手持自拍杆拍照的搞笑图片)and

me（此处重读，突出对比和戏谑，展示自己的一张自拍照）. Yes,cellphones sometimes really make us relaxed. Now, please look at the words on the blackboard, what does “self” mean? (自己)Good! Go on! Now just guess the meaning of this word selfish(自私的), selfishness（自私）, unselfishness（无私）. It seems that we can add a prefix like “un”or a suffix like “ish”

“ness”

to get a new word. And we can also compound a word with another to get a new word like “selfie stick” & “self-introduction”.（手指向黑板）

Yes, it seems that we can add a “prefix”

or a “suffix”(板书：在-un，-ish,-ness（下方划下划线并写上

prefix 和suffix）) and compound with other words to get a new word.Then “What does prefix mean?”(前缀),”What does suffix mean?（

后缀）” and “What does compound mean?（合成）” English is really an interesting language and it is helpful for us to learn some new words. And this is what we will learn in today’s lesson,about how some words are formed in English. It is called “Word Formation ”. This is the teaching goals today.

教学目标：

通过归纳总结的方式，了解英语中常见的前缀（in-，im-, un-, dis-, re-等

），后缀-tion, -ation ,ness，-ance, -ful, -ly, -y, -al 等)。学会根据词根来猜词，了解部分前缀或后缀的含义并注意有些词（如easily, valuable等）的拼写，扩大词汇量，增强英语学习的兴趣。

教学重点：

了解部分前缀或后缀的含义并注意有些词（如easily, valuable等）的拼写。

(学生看PPT，教师可以用英文解释We will learn some “prefixes and suffixes”. And pay more attention to the meaning of them and the spelling of some words.) 〖设计意图〗创设贴近学生生活经验的语境，引出话题，激发学生参与学习和体验语言的兴趣，感受在自然语境中习得prefix, suffix,compound等词汇的含义。

在此基础上概括具体语言形式的结构意义和使用规律，并形成一定的学习策略。“自学互学”就是个人自学能力或分组合作方法的提升。是了解学什么和解决怎么学的内化过程，同时也是教师摸底检查学生基础知识的过程。是对备学生的一个检验，以便下一步的指导学习。

Step3 学习指导

Till now,we have learned some basic rules of Word Formation. It is made up of three kinds. Besides these, I want to tell you some more

about it. Look at the screen, please. ★注意（1）＊否定前缀表示“相反”，mis- 表示“错误”

如：mislead,

misunderstand, mistake ＊-able 表示“能够”

“值得”“可,易……”如：eatable（能食用的），

changeable（易变的，可改变的）

＊

-ful表示“充满了……”

如：beautiful,

wonderful(充满了“奇迹”意思为“精彩的”),

colorful（充满了“色彩”，意思为“多姿多彩的”）

＊

-less表示“无，没有”

如：endless（无尽的），homeless，hopeless ＊en前缀表示，“使成为某种状态”

后缀表示“使”，

“

使变得”

如：enlarge（扩大），enable（使能够），frighten（使害怕），shorten（使变短）

＊否定前缀还有：illegal，irregular,

abnormal，non-stop anti-war(反战的) ★注意(2)：形容词加

ly 变副词时的拼写变化：

complete---completely(千万不能去掉-e);

nice---nicely(千万不能去掉-e) careful---carefully;(直接加-ly )

possible—possibly(去掉-e,加-y)，

simple—simply(去掉-e,加-y);

angry—angrily（改-y为-i,再加-ly），

easy--easily（改-y为-i,再加-ly）; ★注意(3)：名词加able变形容词的拼写规律：

comfort---comfortable （直接加-able）

love---

lovable (去掉-e,加-able) value---valuable (去掉-e,加-able) change--- changeable (千万不能去掉-e,加-able) notice-- noticeable(千万不能去掉-e,加-able) This is what you should pay attention to when dealing with exercises about Word Formation. Do remember them well. 〖设计意图〗在上一个环节学生的直观的感受和判断之后，再有老师横向和纵向的相关思考的点拨，核心知识进行演示，解析指导。这也是课堂深化的表现之一。
