Three Creativity Challenges from IDEO’s Leaders




Three Creativity Challenges from IDEO’s Leaders

People often ask us how they can become more creative. Through our work at the global design and innovation firm IDEO and David’s work at Stanford University’s d.school, we’ve helped thousands of executives and students develop breakthrough ideas and products, from Apple’s first computer mouse to next-generation surgical tools for Medtronic to fresh brand strategies for the North Face in China. This 2012 HBR article outlines some of the approaches we use, as does our new book, Creative Confidence:  Unleashing the Creative Potential Within Us All. One of our top recommendations? Practice being creative. The more you do it, the easier it gets.
Of course, exercising your mind can sometimes feel more daunting than exercising your muscles. So we’ve developed ten creativity challenges to jump-start your practice. Some you can do by yourself; some require a team. Some seem incredibly simple; others you might find more challenging. Three are presented below; we hope you’ll try at least one.
p213-web2
CREATIVITY CHALLENGE #1:  PUSH YOURSELF TO THINK DIVERGENTLY
Mindmaps are a powerful way to overcome fear of the blank page, look for patterns, explore a subject, come up with truly innovative ideas, record their evolution so you can trace back in search of new insights, and communicate your thought processes to others. While lists help you capture the thoughts you already have, mindmaps help to generate wildly new ones. They are extremely versatile, and we use them all the time, not only at work but also at home, for example, to come up with dinner party ideas. (See illustration.)
TOOL: Mindmap
PARTICIPANTS: Usually a solo activity
TIME: 15–60 minutes
SUPPLIES: Paper (the bigger the better) and pen
INSTRUCTIONS:
  1. On a large blank piece of paper, write your central topic or challenge in the middle of the paper and circle it.
  2. Ask yourself, “What else can I add to the map that is related to this theme?” Write down ideas, branching out from the center, and don’t worry if they feel clichéd or obvious. That happens to everyone.
  3. Use each connection to spur new ideas. If you think one of your ideas will lead to a whole new cluster, draw a quick rectangle or oval around it to emphasize that it’s a hub.
  4. Keep going. As the map progresses, your mind will open up, and you’ll likely discover some wild, unpredictable, dissociative ideas .
  5. You are done when the page fills or the ideas dwindle. If you’re feeling warmed up but not finished, try to reframe the central topic and do another mindmap to get a fresh perspective. If you feel you’ve done enough, think about which ideas you would like to move forward with.
p221-web
CREATIVITY CHALLENGE #2: JUMP-START AN IDEATION SESSION
We learned this 30 Circles exercise from David’s mentor, Bob McKim. It’s a great warm-up and also highlights the balance between fluency (the speed and quantity of ideas) and flexibility (how different or divergent they are).
TOOL: 30 Circles
PARTICIPANTS: Solo or groups of any size
TIME: 3 minutes, plus discussion
SUPPLIES: Pen and a piece of paper (per person) with 30 blank circles on it of approximately the same size.
INSTRUCTIONS:
  1. Give each participant one 30 Circles sheet of paper (see example) and something to draw with.
  2. Ask them to turn as many of the blank circles as possible into recognizable objects in three minutes.
  3. Compare results. Look for the quantity or fluency of ideas. Ask how many people filled in ten, 15, 20, or more circles? (Most people don’t finish.) Next, look for diversity or flexibility in ideas. Are the ideas derivative (a basketball, a baseball, a volleyball) or distinct (a planet, a cookie, a happy face)? If people were drawing their own circles, did anyone “break the rules” and combine two or more (a snowman or a traffic light)? Were the rules explicit, or just assumed?
p222-web
CREATIVITY CHALLENGE #3: LEARN FROM OBSERVING HUMAN BEHAVIOR
You’ve gone into the field in search of knowledge, meeting people on their home turf, watching and listening intently. Now synthesize all that data by creating an “empathy map”.
TOOL: Empathy Map
PARTICIPANTS: Solo or groups of two to eight people
TIME: 30–90 minutes
SUPPLIES: Whiteboard or large flip chart, Post-its, and pens
INSTRUCTIONS:
  1. On a whiteboard or a large flip chart, draw a four-quadrant map. Label the sections with “say,” “do,” “think,” and “feel,” respectively.
  2. Write down each of your key observations from the field on one Post-it note and populate the “say” and “do” quadrants. Try color-coding, for example, using green Post-its for positive statements and actions, yellow for neutral, and pink or red for frustrations, confusion, or pain points.
  3. When you run out of observations (or room) in those quandrants, begin to fill the “think and” and “feel” sections with Post-its, based on the body language, tone, and choice of words you observed. Use the same color coding.
  4. Take a step back and look at the map as a whole. What insights or conclusions can you draw from what you’ve written down. What seems new or surprising? Are there contradictions or disconnects within or between quadrants? What unexpected patterns appear? What, if any, latent human needs emerge?

蓋茨的人生箴言


In a Speech to Mt. Whitney High School graduates in Visalia, California, Bill Gates reminded them of a list of 11 things that they did not learn in school. Bill Gates talked about how feel good, politically-correct teachings created a full generation of kids with no concept of reality and how this education set them up for failure in the real world. 在比爾-蓋茨給高中畢業生的講話裏,列出有11項學生沒能在學校裏學到的事情。比爾-蓋茨在講話中談到讓你感覺良好的政治上正確的教導培養出一整代不知現實為何物的年輕人,這種教育隻能導致他們成為現實世界中的失敗者。
These 11 things are
11項事情是:
Life is not fair, get used to it.
生活是不公平的;要去適應它。
The world won’t care about your self-esteem. The world will expect you to accomplish something before you feel good about yourself. 這世界並不會在意你的自尊。這世界指望你在自我感覺良好之前先要有所成就。
You will not make 40 thousand dollars a year right out of high school. You won’t be a vice president with a car phone until you earn both. 高中剛畢業你不會一年掙4萬美元。你不會成為一個公司的副總裁,並擁有一部裝有電話的汽車,直到你將此職位和汽車電話都掙到手。
If you think your teacher is tough, wait till you get a boss. He doesn’t have tenure. 如果你認為你的老師嚴厲,等你有了老闆再這樣想。老闆可是沒有任期限製的。
Flipping burgers is not beneath your dignity. Your grandparents had a different word for burger flipping; They called it opportunity. 烙牛肉餅並不有損你的尊嚴。你的祖父母對烙牛肉餅可有不同的定義;他們稱它為機遇。
If you mess up, it’s not your parents fault, so don’t whine about our mistakes, learn from them. 如果你陷入困境,那不是你父母的過錯,所以不要尖聲抱怨我們的錯誤,要從中吸取教訓。
Before you were born, your parents weren’t as boring as they are now. They got that way from paying your bills, cleaning your clothes and listening to you talk about how cool you are. So before you save the rain forest from the parasites of your parents’ generation, try delousing the closet in your own room. 在你出生之前,你的父母並非像他們現在這樣乏味。他們變成今天這個樣子是因為這些年來他們一直在為你付賬單,給你洗衣服,聽你大談你是如何的酷。所以,如果你想消滅你父母那一輩中的寄生蟲來拯救雨林的話,還是先去清除你房間衣櫃裏的蟲子吧。
Your school may have done away with winners and losers, but life has not. In some schools they have abolished failing grades They’ll give you as many times as you want to get the right answer. This doesn’t bear the slightest resemblance to anything in real life.
你的學校也許已經不再分優等生和劣等生,但生活卻仍在作出類似區分。 在某些學校已經廢除不及格分;祗要你想找到正確答案,學校就會給你無數的機會。這和現實生活中的任何事情沒有一點相似之處。
Life is not divided into semesters. You don’t get summers off and very few employers are interested in helping you find yourself. Do that on your own time. 生活不分學期。你並沒有暑假可以休息,也沒有幾位雇主樂於幫你發現自我。自己找時間做吧。
Television is NOT real life. In real life people actually have to leave the coffee shop and go to jobs.
電視並不是真實的生活。在現實生活中,人們實際上得離開咖啡屋去幹自己的工作。

Be nice to nerds. Chances are you’ll end up working for one.

善待乏味的人。有可能到頭來你會為一個乏味的人工作。

“五段互動式”培訓

五段互動式培訓:
讓更多的教師動起來

深圳市寶安區小學教師培訓模式實踐探索
    (作者系廣東省深圳市寶安區教育科學研究培訓中心主任)
http://www.zhyww.cn/teacher/201012/38605.html


  教學新模式
為了迎合新時代,不少學校及教師不斷改良教學模式,讓學生能夠得到最佳的發展。福建中學為慶祝遷校十周年暨邁向校慶六十周年,於上月舉行「全港教學觀摩日」,並於當日示範教師專業發展新模式培訓「五段互動式」。
「五段互動式」由福建中學與深圳寶安區教育科學研究培訓中心合辦,是經過度身訂造、精心研發而成的教師專業發展新模式。新式教學注重教師學用結合,從激辯中啟發反思、從反思中促進成長,加強教師與學生的創意互動,令學生積極投入課堂學習,實用性高,成效顯著,進一步為學生提供優質教育及推動教學發展。
  變接受式培訓為參與式培訓
  傳統的中小學教師培訓方式一般是專家臺上講,教師台下聽,這是一種接受式培訓,參訓教師被動學習,參與程度不高,只能適合於傳遞性的知識、理論觀念、教育資訊等方面的培訓。在培訓中,接受式培訓雖然也是一種重要的培訓模式,但考慮到中小學教育的實踐性質,參與式培訓事實上更具有實效性,也更容易為中小學教師所接受。參與式培訓是一種以問題為中心的參與式學習和探索性學習,在內容上,它宣導將培訓和教學有效結合起來,搭建教育思想與教育行為融合、互通的平臺;在形式上,注重教師的參與和表現,避免教師在培訓完後產生隔岸觀火隔靴搔癢的困境,是一種開放式的培訓。
  基於對上述兩種培訓方式的思考,深圳市寶安區教科培中心在培訓實踐中逐漸探索,總結出了一種新型的區域教師培訓模式——“五段互動式培訓模式。該模式分為主題講座——課例實踐——辯課互動——點評提升——研究反思五個環節與階段。其主導思想是要由過去的以接受式培訓為主轉到以參與式培訓為主上來,實現理論與實踐的整合,推進教師培訓的優質化、高效化。這種模式強調培訓者與參訓教師、參訓教師與參訓教師之間的多向交流與互動,運用多種手段調動參訓教師參與各項培訓活動,發揮參訓教師的主體性,使參訓教師在參與中感受思想的衝擊力,形成自身的教育信念,又能學會處理各種教育教學問題的技能和策略,實現學用結合。
  讓全體參訓教師都動起來
  五段互動式培訓模式的基本思路大致可以表述為:思想引領——實踐研修——形成教師個人教育信念和行為。根據這個思路,我們在具體設計培訓模式時,在內容上,既有理論的衝擊,也有實踐的觀照,還有教師個人的研究反思;在形式上,讓全部參與者都動起來,在多個環節都增加了專家與教師、授課者與教師、教師與教師之間互動辯論,真正實現了從教育理念到教育行為的轉換和內化。
  主題講座。由教育專家或學科專家結合新課程改革以及教育教學實際,選擇一個教育教學主題,講授有關的理論觀點以及課堂教學中的應用方法,幫助教師用理論去指導教學實踐活動。
  從目的來看,主題講座作為五段互動式培訓中的專業引領部分,其作用主要是針對目前課改中出現的熱點、重點、難點、焦點問題,進行理論引領。因此,主題講座的目的是在探索有效課堂教學的方法和手段的過程中,及時發現問題,研究問題,找到解決問題的方法,把問題上升到理論的高度,尋找理論依據,用理論指導行動。從物件上來看,講座的聽眾是一線教師,都有一定的教育教學理論基礎和教學經驗,因此,選擇講座內容應該是貼近實際,較為具體的問題。如果選題過於抽象寬泛,講座者很容易漫無邊際,使參訓者雲裡霧裡,甚至感覺講座者有賣弄之嫌,其效果大打折扣。
  課例實踐。根據專家專題講座的主要思想和核心理論,組織課程培訓團隊,進行課堂教學設計,並選拔一位全區優秀的青年教師現場授課,通過授課把專家的專題講座內化為實際操作層面的課堂教學,是原生態的、本真的教學。這一階段的基本思路是,利用青年教師所在學校學科組和課程培訓團隊的力量,圍繞培訓專題的理念,幫助青年教師進行課堂教學設計。這樣既體現個人風格,又體現學校教研水準與課程團隊的實力,更體現培訓專題的理念,實現四者融合,為參訓者提供可借鑒、可操作的行之有效的教學行為。
  辯課互動。參訓教師圍繞專家的主題講座,結合青年教師的課例,正反雙方各選四位辯手,展開針鋒相對的辯論。正反雙方從不同角度探討有效的教學策略,尋找課堂教學的真諦,使教師對專家講座的理念,怎樣圍繞主題構建高效的課堂教學模式有清晰的理解和深刻的把握。
    辯課在說課、評課的基礎上發展起來,但又與說課、評課有本質的不同。說課、評課是上課老師與聽課老師各說各話,互相沒有交流與碰撞,很難產生共鳴。而辯課的核心是,是一種以課堂實踐為靶子的辯論式評課,它強調民主、對話、參與,注重獨立思考,鼓勵思想碰撞。辯課就其價值和意義而言,一是完善提高,二是深度挖掘。即明晰不同教學策略的不同效果,厘清認識上的差異,改善教育行為,從而更有效指導自身的教育教學實踐。因此,辯課首先要避免你輸我贏的意識,不能為辯而辯,而是利用辯論這一束陽光,照亮思維的盲區,照亮我們思維的死角,讓自己的思想更加敞亮。其次,辯論的結果不能留下一鍋糊粥。辯論雙方據理力爭,但不一定就非對立著辯不可,而更應該是趨同地辯,真正實現越辯越明瞭,越辯越富科學性、藝術性。辯完之後,應該是大家都獲得了某種程度的提高。這種提高,或許是努力改良這一節課的教學流程,以提高教學效率;或許是不斷改良一種理念在教學中的實踐操作,使之更有效地得以實施與推廣;或者改良一位老師的課堂教學技藝,促其更快更好地成長、成熟,等等。
    點評提升。由名師現場對課堂教學行為與辯課情況進行歸納、評價、提升,進行適時的專業引領,提出方向性的意見和看法,形成正確的評價導向,使教師更好地領會理論的精髓,掌握課堂教學的藝術。
    由於在辯課前安排了正反兩方,容易形成哪一方辯手水準高,哪一方就佔上風,而不是誰的觀點正確誰佔上風的錯覺。此時,應由一位既有理論權威又有實踐經驗、能讓教師信服的名師,或幾位能力較強的人達成共識並形成正確的評價導向後推舉的代表發言,及時地根據專家講座理念、聽課與辯課感受,現場對課堂教學行為與辯課情況進行歸納、評價、提升,進行適時的專業引領,提出方向性的意見和看法。這樣就會使受訓教師更進一步地領會專家講座精髓,更有效地吸取課堂教學所提供的可借鑒的好經驗、好方法,更有利於把培訓中發現的問題作為一種可供開發的資源進行更有意義的反思與建構。如此,受訓教師方向明,目標清,培訓效益更大。
    研修反思。由參訓學員結合現場學習,歸納收穫和啟發,反思自己日常教學中需要改進的地方,並將培訓中獲得的知識和技能在課堂教學中實踐,提高自己的教學能力,提高課堂教學的效果。
    研修反思包括撰寫研修日誌和受訓後的微格演課兩個內容。研修日誌的內容可以針對主題講座、新秀授課、同行互辯、專家點評等任何一個環節,可以是感悟,也可以是反思。撰寫的原則是:

1)一事一得。要主題集中、有針對性地描述某一個故事。

2)夾敘夾議。在寫作手法上,通常邊敘述故事情節,邊滲透一些對細節的感悟。

3)注重細節。儘量選取能引起同行共鳴、難以操控、意蘊深刻、值得反思的細節。撰寫研修日誌是讓教師思考為什麼,如何才能做得更好,而微格演課則讓教師檢驗我是否可以,努力實現預期。微格演課的要求是:

1)演課和說課要有機結合。

2)教學過程要求教師做忠實記錄,除攝像機全程錄影外,每位元聽課者都要認真記錄,以便在評課時能有的放矢。

3)學科組和教研組成員共同參與、共同研究,實現同伴互助。

    實現理論與實踐的融合
  五段互動式培訓由過去對教師進行新課程理念的培訓進入到課堂教學模式和教師教學技能的培訓,由過去的臺上講臺下聽的純理論式培訓轉到臺上台下互動研討的開放式培訓,將培訓與教學緊密結合,有理論指導,有課堂示範,有教學研討,克服傳統教師培訓中理論與實踐脫節的弊端,較好地實現學用結合的培訓目的。在這個模式中,互動環節的增加,起到了拾遺補缺、調節氣氛和節奏、提升受訓教師參與積極性的作用。在情感與理性、常識與偏見、技巧與常態、理念與課例之間,實現智慧碰撞、思想砥礪、觀念融合,既加深了對專題、課例的理解與認識,又發揮其已有知識和實踐經驗的潛能,提高對現實問題的洞察與分析能力。

學科教師展示活動出新意  五段互動教師培訓效果好
1021日上午,在濱海小學4樓多功能廳,深圳市教科院小學科學與寶安區教科培中心聯合舉辦了小學科學業成就評價課題暨優秀教師教學展示活動。參加此次活動的有寶安區教科培中心潘世祥主任、深圳市教科院小學科學童海雲教研員、南山區安林之教研員、區教科培中心教科所朱利霞博士、張明春老師、寶安區各小學科學任課教師、寶安區初中各學科五段互動式培訓團隊成員、各區小學科學教師代表、廣東省名師工作室骨幹教師跟崗學習學員。本次培訓共350多人參與了活動。
潘世祥主任在講話中闡明了五段互動式培訓的意義和這種培訓模式對培養教師所產生的直接作用,同時也簡單介紹了寶安區五段互動式培訓模式在國內外所產生的良好影響。
本次研討課由濱海小學的高春豔老師承擔,她的課題是六年級的《電磁鐵》。高老師巧妙的教學設計、乾淨俐落的教學風格,把全場的師生帶進了探索電磁鐵的世界,整個過程充分展示了學業評價對學生學習產生的良好影響,同時也對如何在課堂上自然融入學業評價做了一個很好的探索。老師和學生們精彩的互動引來了全場老師的陣陣喝彩。
寶安區教科培中心教研員唐雲波老師做了《基於課標的教評一體化課堂教學的研究》的專題講座。他以來發生在著名教育家陶行知身上的一個案例生動的說明了學業評價要以發現和發展學生潛能、保護學生自尊心、關注學生心理需要為原則,強調要建立與新課標的評價理念和要求相適應的學業成就評價體系,同時介紹了教————評一體化課堂教學模式的理念和操作方法。唐老師的講座對老師們提升理論水準和實踐能力都起到很好的指導作用。
本次活動的辯課階段十分精彩,正反方一辯在立論陳詞階段,觀點明確、思路清晰、有理有據,高度概括了課堂的優點和不足;在輪流攻辯和自由辯課階段正反雙方緊扣論點,你來我往,妙語連珠,針對對方的話題,抓住漏洞給予有力的反駁;最後,伴著聽課老師的熱烈掌聲,在正反方四辯熱情洋溢、簡潔明瞭的總結陳詞中結束了這場精彩紛呈的辯課環節。
本次五段式互動培訓點評階段。童海雲老師對本次研討課、培訓模式和承辦學校給予了高度的讚揚,同時給科學老師的教育教學作了專業的指導。童老師說到,評價是一件非常複雜的事,它體現了教師的價值取向,從今天的課堂上給我們一個很大的啟示,那就是要瞭解我們的學生就要給他表達的機會,這是評價的起點和基準。學生表達機會不僅體現為課堂上的發言,更重要的是書面表達,參與書面表達學生更多,更能反映學生對探究問題的思維加工過程,更能真實反映學生的現有狀態。比如在今天的課堂上,高老師要求學生制定探究電磁鐵南北極的實驗方案,然後智慧地選擇典型的方案,引導學科形成好的實驗方案的評價標準。童老師還提到作為科學老師,要抓住一個根本,學科學關健的不僅做實驗,也不僅討論,更重要的要引導學生不斷的協調自我觀點和實驗證據之間的關係;他還強調,我們的課堂要促進集體反思,要營造一種讓學生通過做實驗取證,通過動手實驗明白很多東西的氛圍。
本次培訓的一大亮點就是全場充滿了參與的精神,多功能廳右前方的電子螢幕上不停的滾動著聽課老師互動的心聲,他們積極參與了每一環節,他們或認同讚揚或提出不同的看法,充分體現了五段互動式的精髓——求真求實,全員參與。雖然小學科學是第一次五段式培訓,但是由於組織者科學嚴謹的工作態度,使得五段式培訓的優勢得到了淋漓盡致的發揮。
