【課的設計與思考】
一、教學內容的分析
1.教材的地位和作用。
Population Movement in the USA 所在單元的話題是“People on the move”。作為閱讀課的第二課時,其功能是幫助學生在已經了解課文文本的基礎上進行語言層面的習得,并學以致用,在輸入后圍繞該話題及時進行輸出操練。
2.教學重點和難點。
翻轉層面:翻轉課堂的“冰山理論”決定了大部分的工作都是在課堂之外,而課堂的呈現只是冰山一角,并且翻轉課堂中教師和學生的角色,給這節課帶來的重難點是如何分組、如何條理清晰地有效地布置任務。
教學層面:文本Population Movement in the USA條理清晰,語言精煉,但其所談論的話題涉及社科類的知識,或許是學生平時并不太思考的,因此本節課的重、難點確定為:
(1)重點:由點到面對文本中的重點詞匯、短語、句子進行習得。
(2)難點:運用所學的知識進行話題寫作。
二、教學目標的確定
1.知識與技能:從文本角度,通過文本閱讀進行語言層面的習得,并在此基礎上用所學語言圍繞本單元話題進行相關話題寫作;從翻轉課堂的角度,通過小組合作研讀教師的資料包進行大量的課前整理、消化、提取工作,在此過程中小組先進行知識內化、優化。
2.過程與方法:從文本的角度通過高考任務型閱讀的題型來復習閱讀課第一課時的內容從而引出要學的詞匯和短語,讓學生了解這些詞匯和短語在文本中的用法和含義并通過多方式對這些詞匯和短語進行拓展和操練;然后從語言審美的角度和語法的角度去系統地賞析一些句子,由點到面為后續的相關話題寫作輸出做鋪墊。從翻轉課堂的角度,教師需要對學生進行分組,根據設計把學生分成五組,即復習組(the Review Group)、詞匯組(the Word Bank Group)、短語組(the Phrase Group)、句子組(the Sentence Group)和寫作組(the Writing Group);并對各個小組布置明確和有效的任務。
3.情感態度價值觀:從翻轉課堂的角度,讓學生進行小組活動,培養學生自主學習能力、合作能力和分享精神;從文本的角度,培養學生對話題思考分析的能力,進行有效寫作。
三、 教學方法的選擇
從翻轉課堂的角度,通過學生課外的task-based的小組活動讓學生自主學習,通過和教師的不斷溝通和交流完善自主學習內容,以便展示課上與同伴分享。這種活動的好處是小組活動取代了教師的講,這樣一種自主學習和同伴習得會讓學生對知識的記憶更加牢固,教師的身份轉變為活動的設計者、方法建議者、課后咨詢者、展示課堂的協調者。
從文本的角度,閱讀第二課時的主要內容在于語言層面的輸入,因此教師在布置任務時提出的習得方式要多樣,讓盡可能多的其他小組的學生涉及其中,確保輸入的高效性。
四、教學過程的設計
本節課設計教學過程總體流程為:
【課例呈現】
Step 1 Warm-up and review part
T:Morning you guys. We are on the move,from our little bit shabby classroom to this fancy place.(在黑板上板書People on the move) It is a trial lesson of flipped class. I am the person behind the curtain while my students are the heroes today. Id like to invite the representative(以下簡稱“R”)from Group 1,the Review Group to take the floor.
R1:Weve learned that the people in the USA are always on the move. What are the two trends mentioned in the text?
S:The aged move to Florida and the young move to big cities.
R1:Yes. Lets fill in the blanks with proper words.
(Keys:1. move; 2. permanent; 3. aged; 4.preference; 5. slipping; 6. makes; 7. cater; 8. boom; 9. electing; 10. swap)
學生回答時教師在黑板上板書出age,slip, boom,swap,on the move,make sense,cater to這些詞和短語,讓本節課學習的目標詞匯在黑板上一目了然地呈現出來。
T:Thank you the Review Group, the words colored on the screen are what we are going to learn. Please welcome Group 2, the Word Bank Group.
Step 2 Word Study
R2:Im the representative from the Word Bank group. Id like to share what our group prepared with you.Would you please translate the following sentence: Lin Qingxia is in her 60s,but has (優雅地老去).

S:學生回答。
R2:What is the difference between the two “aged”s?
S:學生回答。
R2:The first means“at the age of”while the second means“very old”. OK,so much for the word “age”. Id like to ask you a question: What are the possible results of the coming quotas of car plates(車輛限牌)in Nanjing?
T: To be specific,what will you do now if it will be quite difficult for you to get a car plate license next month?
(見學生面露難色,教師在翻轉課堂展示課中的作用就顯現出來了,即引導學生往前走。)
S: 學生回答。
(意圖:以數月前南京限牌的民間議論為引子想引導學生說出boom這個詞,但是課堂中有學生回答出:There will be an increase in car sales. 教師的角色就在此,引導問increase的同義詞是什么,學生們眾口說出boom,從而引出boom的用法。)
R2:Here“boom”is a noun, meaning“a sudden increase in trade and economic activity”. See the sentence in the textbook:Recently,there has been a boom in population movements,...(L34)
An open sentence for you, please complete the following sentence: 2015 will be a boom year for .
S:學生回答。
(開放式造句,讓學生發揮想象空間,更好地記住該詞的用法)
R2:Remember “a boom in sth”. “boom” can be used as a verb. Therefore we can say “the car sales will boom.” Would you please say something about the following picture by using “boom”?
S: 學生回答。
R2帶領同學們把投影上所列出的有關boom的例句誦讀一遍。然后在投影上打出下面這個句子:
I didnt mean to tell you the secret; it was a of my tongue at that time.
(A.swap B.skip C.scan D.slip )
(答案為D. 從而引出對slip一詞的學習。)
R2:What does slip here mean?
S:學生回答。
R2:“slip” here means“a minor error”. What does“slip”mean in the textbook?Would you please find the sentence with “slip”?
S:學生回答。
R2總結slip作為名詞的用法,引出其作為動詞的使用,并提醒學生其過去式、過去分詞、現在分詞要雙寫 “p”。
R2:Lets see two sentences: 1. Caution!Dont slip on the wet floor. 2. His name slipped my mind/memory. Try to guess what two “slip”s mean.
S:學生回答。
R2總結,并給出一些語境進行操練:
(翻譯)時間正悄悄溜走。
(補全句子)他沒抓住凱利, 讓她給逃脫了。 Cally his grasp and fled.
然后帶領全班同學把所有例句誦讀一遍。
R2:Would you please replace the underlined part of the following sentence“Young mobile adults give many different reasons for leaving and replacing their home towns with big cities”?
S:學生回答。引出對“swap”這個詞的講解。
R2:It has two meanings. The first one is “to replace one thing with another”, the second is “to exchange”. Please translate the following sentence into Chinese: Flipped class is to swap roles between teachers and students.
S: 學生回答。
重點詞匯講解完后以填空的形式提及一下次要重點詞匯:
1.At the age when most people r ,he is ready to face a new career.
2.The government needs a more f approach to education to meet different demands.
3.Are you looking for a temporary or a p job?

Step 3 Phrase learning
R3:The first phrase we are going to share with you is “on the move” in the title. What does it mean?
S:學生回答。
R3:Please translate the following sentences into English:
1. 公司正在遷往更大的辦公區。
2.我到達火車站時,火車已經開動了。
S:學生回答。
R3:Lets move to the next phrase:“We prefer staying comfortable, and thats why moving somewhere warmer makes sense.”(L19)What does“make sense” mean?
S:學生回答。
R3接著讓學生進行操練:
1.(翻譯)買最新的iPhone是不明智的。
他在會議上對你的指責毫無道理。
告訴你父母你沒有通過考試的真相是明智的,他們遲早會知道。
2.(開放式完成句子) doesnt make sense. 并給予補充:make sense of sth. 和 there is no sense in doing sth.
R3:Do all of you make sense of it?OK,would you please replace the underlined part: As the number of older Americans moving there increases, more changes are made to meet the special needs of them.(L23)?
S: 學生回答。
R3:Please translate the following sentence: Handsome though Peng Yuyan is,the director caters to the audiences expectations to see how he reinterprets the character in the film Rise of the Legand.(《黃飛鴻之英雄有夢》).
這個演員和這部電影是學生感興趣的,接著給出一道選擇題:

(A.submit to B.cater to C.relate to D.object to)
(答案為B.)
Step 4 Sentence learning
T:The representative from ?the Sentence Group will share with us some sentences from two perspectives, one from the grammatical perspective, the other from appreciation of language.
R4:Lets compare the following two sentences, and tell us which one is better.

2)Throughout the Midwest and the North-east, people aged 60 and over are packing their bags and heading south along the freeway to states like Florida.
S:學生回答。
R4:Sentence Number 2 is better. As our English teacher said, writing should follow the principle of economy. It is what we need to learn.
T:Making your sentence short is more difficult than making it long.
R4:Please identify what clauses they are.
1)Id love to stay in the community where I grew up,but there are no career opportunities there. (L51)
2)I have to go where the big companies are because I want to be a top accountant, not a database clerk. (L52)
3)Ambition can drive some young people to the city to be “where the big companies are”.(L55)

Output process
Step 5 Writing
R5:Before we start writing, lets translate some sentences by using the words and phrases weve learnt today.
1) 人口遷移量有所增長。(boom)
2) 老年人遷移到溫暖的城市,而年輕人選擇住在大城市。(on the move;select)
3) 在老年人給出的許多原因中,許多人很看重舒適因素,因此會遷移到溫暖的地方。(make sense)
4) 隨著遷移人口的增多,出現了很多迎合老年人的措施,使得這些城市更具吸引力。(cater to)
5) 年輕人雖然觀念不同,但是他們前往共同的目標——城市。(head for)
6) 年輕人對遷移到大城市有著不同的理由,如找好的工作或尋求樂趣。(swap...for...)
7) 城市有著先進的設備,能為人們提供更好的生活。(equip with)
該翻譯任務既是對已學內容的再現,又是為下面的寫作任務做準備,翻譯完后給出寫作任務:
“人口遷移”是當今每個國家都存在的普遍現象,在中國也愈加顯著。下面是“老年人和年輕人在選擇移居城市”的調查結果,請閱讀表格并按照要求完成一篇150詞左右的文章。
1)簡述表格中反映的現象;
2)說說產生這種現象的原因;
3)談談你自己對該現象的看法。
R5:Add some linking words to make the sentences you translated just now the body part of your composition. And take the rest part as your homework.
T:Thank you. About Paragraph One of this composition, it is not necessary to list all the figures.
(意圖:在課前與寫作小組的學生溝通交流,要求他們要和前面的小組保持好溝通,設計好寫作任務,把已學的內容放到他們的寫作任務中去,學以致用。)
【課后反思】
本節翻轉課堂的設計是走兩條線:一、課前設計;二、展示課堂。基于翻轉課堂的“冰山理論”,八分之七是第一條線:課前的規劃和師生溝通。這節閱讀課第二課時如何分組?每組的任務具體是什么?這些必須給學生明確的指令以便他們在自學準備時目標明確。后續的四次師生溝通中教師提出修改建議以完善呈現內容,最后確定展示課時要分享的內容。八分之一就是45分鐘的課堂展示。總體說來學生的小組學習是有效的,展示內容的準備是按照任務指令走的,不足即是我們的學生在做Presentation時的自信和儀態還需鍛煉。
翻轉理念下的同伴學習對學生產生的積極影響和作用大于教師的單一授課,不足是高考壓力下學生的自主同伴學習時間少,翻轉理念的推行需要時間。
【點評】
這節課教學目標清晰,教學重難點把握準確,特別是在教學方法上進行了創新。本節課課堂教學效果好,給人留下了深刻印象。
在教學目標設定方面,王老師根據課時特點和學生學情將其定位為詞匯短語的習得,對詞匯和句子表達方式的賞析,為相關話題寫作進行討論和準備,通過小組合作學習培養學生的自學能力、合作能力和分享意識等。教學目標定位非常清晰,思維層次和能力要求較高。
在教學重難點把握方面,教學內容層面主要是重點詞匯短語的習得和話題寫作的準備,教學方法層面主要是翻轉課堂之外的學習活動,如分組和布置學習任務等。王老師在備課過程中能夠對教學的重難點進行比較準確深入的預判,體現了她優秀的專業素養和能力。
在教學方法上王老師結合翻轉課堂理論進行了大膽創新,這也是這節課最大的亮點之一。通過課外的分組自主學習,學生在和教師的不斷溝通和交流中完善并完成自主學習內容, 然后在課堂上和同學分享。這種教學方法明顯的好處是學生的學習積極性和參與度得到很大的提高,學習資源和學習方式擺脫了課堂的局限。這種教學對教師的教學能力也提出了巨大挑戰,教師成為活動的設計者、方法建議者、課后咨詢者和展示課堂的協調者。
最終,經課前學生自主學習和師生間多達四次的溝通交流,在課堂教學環節,復習組的學生對文本內容進行結構重組和信息梳理,在設計中巧妙引出本節課要學習的重點詞匯。詞匯短語組的學生挑選重點詞匯和短語和同學分享,并提供了大量包含最新時事和娛樂信息的句子,激發學生的學習興趣,有利于學生在真實語境中使用所學的詞匯短語。句子組和寫作組的學生關注到一些特殊的語法結構及其含義,然后進行了相關話題的詞匯支撐及觀點表述等方面的討論,將詞匯和語法習得的層次進一步提升到一個較高水平,實現了從知識到能力的轉化。
總之,本節課從創意設計到具體實施都讓人耳目一新,令人深受啟發。
