TED: 怎樣從錯(cuò)誤中學(xué)習(xí)
Diana Laugenberg:How to learn? From mistakes
講者分享了其多年從教中所認(rèn)識(shí)到的一從錯(cuò)誤中學(xué)習(xí)的觀念“允許孩子失敗,把失敗視為學(xué)習(xí)的一部分”,以及從教育實(shí)踐中學(xué)到的三件事:“1.體驗(yàn)學(xué)習(xí)的過(guò)程 2.傾聽學(xué)生的聲音 3.接納錯(cuò)誤的失敗。” TED演講文本:
0:15 I have been teaching for a long time, and in doing so have acquired a body of knowledge aboutkids and learning that I really wish more people would understand about the potential ofstudents.In 1931, my grandmother--bottom left for you guys over here--graduated from theeighth grade.She went to school to get the information because that's where the informationlived.It was in the books;it was inside the teacher's head;and she needed to go there to getthe information, because that's how you learned.Fast-forward a generation: this is the one-roomschoolhouse, Oak Grove, where my father went to a one-room schoolhouse.And he again hadto travel to the school to get the information from the teacher, stored it in the only portablememory he has, which is inside his own head, and take it with him, because that is howinformation was being transported from teacher to student and then used in the world.When Iwas a kid, we had a set of encyclopedias at my house.It was purchased the year I was born,and it was extraordinary, because I did not have to wait to go to the library to get to theinformation.The information was inside my house and it was awesome.This was different thaneither generation had experienced before, and it changed the way I interacted with informationeven at just a small level.But the information was closer to me.I could get access to it.1:34 In the time that passes between when I was a kid in high school and when I started teaching,we really see the advent of the Internet.Right about the time that the Internet gets going as aneducational tool, I take off from Wisconsin and move to Kansas, small town Kansas, where Ihad an opportunity to teach in a lovely, small-town, rural Kansas school district, where I wasteaching my favorite subject, American government.My first year--super gung-ho--going toteach American government, loved the political system.Kids in the 12th grade: not exactly allthat enthusiastic about the American government system.Year two: learned a few things--hadto change my tactic.And I put in front of them an authentic experience that allowed them tolearn for themselves.I didn't tell them what to do or how to do it.I posed a problem in front ofthem, which was to put on an election forum for their own community.2:27 They produced flyers.They called offices.They checked schedules.They were meeting withsecretaries.They produced an election forum booklet for the entire town to learn more abouttheir candidates.They invited everyone into the school for an evening of conversation aboutgovernment and politics and whether or not the streets were done well, and really had thisrobust experiential learning.The older teachers--more experienced--looked at me and went, “Oh, there she is.That's so cute.She's trying to get that done.”(Laughter)“She doesn't knowwhat she's in for.” But I knew that the kids would show up, and I believed it, and I told themevery week what I expected out of them.And that night, all 90 kids--dressed appropriately,doing their job, owning it.I had to just sit and watch.It was theirs.It was experiential.It wasauthentic.It meant something to them.And they will step up.3:17 From Kansas, I moved on to lovely Arizona, where I taught in Flagstaff for a number of years,this time with middle school students.Luckily, I didn't have to teach them American government.Could teach them the more exciting topic of geography.Again, “thrilled” to learn.But what wasinteresting about this position I found myself in in Arizona, was I had this really extraordinarilyeclectic group of kids to work with in a truly public school, and we got to have these momentswhere we would get these opportunities.And one opportunity was we got to go and meet PaulRusesabagina, which is the gentleman that the movie “Hotel Rwanda” is based after.And hewas going to speak at the high school next door to us.We could walk there.We didn't evenhave to pay for the buses.There was no expense cost.Perfect field trip.4:04 The problem then becomes how do you take seventh-and eighth-graders to a talk aboutgenocide and deal with the subject in a way that is responsible and respectful, and they knowwhat to do with it.And so we chose to look at Paul Rusesabagina as an example of a gentlemanwho singularly used his life to do something positive.I then challenged the kids to identifysomeone in their own life, or in their own story, or in their own world, that they could identify thathad done a similar thing.I asked them to produce a little movie about it.It's the first time we'ddone this.Nobody really knew how to make these little movies on the computer, but they wereinto it.And I asked them to put their own voice over it.It was the most awesome moment ofrevelation that when you ask kids to use their own voice and ask them to speak for themselves,what they're willing to share.The last question of the assignment is: how do you plan to useyour life to positively impact other people? The things that kids will say when you ask them andtake the time to listen is extraordinary.5:05 Fast-forward to Pennsylvania, where I find myself today.I teach at the Science LeadershipAcademy, which is a partnership school between the Franklin Institute and the school district ofPhiladelphia.We are a nine through 12 public school, but we do school quite differently.I movedthere primarily to be part of a learning environment that validated the way that I knew that kidslearned, and that really wanted to investigate what was possible when you are willing to let go ofsome of the paradigms of the past, of information scarcity when my grandmother was in schooland when my father was in school and even when I was in school, and to a moment when wehave information surplus.So what do you do when the information is all around you? Why doyou have kids come to school if they no longer have to come there to get the information? 5:51 In Philadelphia we have a one-to-one laptop program, so the kids are bringing in laptops withthem everyday, taking them home, getting access to information.And here's the thing that youneed to get comfortable with when you've given the tool to acquire information to students, isthat you have to be comfortable with this idea of allowing kids to fail as part of the learningprocess.We deal right now in the educational landscape with an infatuation with the culture ofone right answer that can be properly bubbled on the average multiple choice test, and I amhere to share with you: it is not learning.That is the absolute wrong thing to ask, to tell kids tonever be wrong.To ask them to always have the right answer doesn't allow them to learn.Sowe did this project, and this is one of the artifacts of the project.I almost never show them offbecause of the issue of the idea of failure.6:45 My students produced these info-graphics as a result of a unit that we decided to do at the endof the year responding to the oil spill.I asked them to take the examples that we were seeing ofthe info-graphics that existed in a lot of mass media, and take a look at what were theinteresting components of it, and produce one for themselves of a different man-made disasterfrom American history.And they had certain criteria to do it.They were a little uncomfortablewith it, because we'd never done this before, and they didn't know exactly how to do it.Theycan talk--they're very smooth, and they can write very, very well, but asking them tocommunicate ideas in a different way was a little uncomfortable for them.But I gave them theroom to just do the thing.Go create.Go figure it out.Let's see what we can do.And thestudent that persistently turns out the best visual product did not disappoint.This was done inlike two or three days.And this is the work of the student that consistently did it.7:39 And when I sat the students down, I said, “Who's got the best one?” And they immediatelywent, “There it is.” Didn't read anything.“There it is.” And I said, “Well what makes it great?”And they're like, “Oh, the design's good, and he's using good color.And there's some...” Andthey went through all that we processed out loud.And I said, “Go read it.” And they're like, “Oh,that one wasn't so awesome.” And then we went to another one--it didn't have great visuals,but it had great information--and spent an hour talking about the learning process, because itwasn't about whether or not it was perfect, or whether or not it was what I could create.Itasked them to create for themselves, and it allowed them to fail, process, learn from.And whenwe do another round of this in my class this year, they will do better this time, because learninghas to include an amount of failure, because failure is instructional in the process.8:29 There are a million pictures that I could click through here, and had to choose carefully--this isone of my favorites--of students learning, of what learning can look like in a landscape wherewe let go of the idea that kids have to come to school to get the information, but instead, askthem what they can do with it.Ask them really interesting questions.They will not disappoint.Ask them to go to places, to see things for themselves, to actually experience the learning, toplay, to inquire.This is one of my favorite photos, because this was taken on Tuesday, when Iasked the students to go to the polls.This is Robbie, and this was his first day of voting, and hewanted to share that with everybody and do that.But this is learning too, because we askedthem to go out into real spaces.9:20 The main point is that, if we continue to look at education as if it's about coming to school to getthe information and not about experiential learning, empowering student voice and embracingfailure, we're missing the mark.And everything that everybody is talking about today isn'tpossible if we keep having an educational system that does not value these qualities, becausewe won't get there with a standardized test, and we won't get there with a culture of one rightanswer.We know how to do this better, and it's time to do better.0:15
我從事教師工作很長(zhǎng)一段時(shí)間了,而在我教書的過(guò)程當(dāng)中 我學(xué)了很多關(guān)于孩子與學(xué)習(xí)的知識(shí) 我非常希望更多人可以了解 學(xué)生的潛能。1931年,我的祖母 從你們那邊看過(guò)來(lái)左下角那位--從八年級(jí)畢業(yè)。她上學(xué)是去獲取知識(shí) 因?yàn)樵谶^(guò)去,那是知識(shí)存在的地方 知識(shí)在書本里,在老師的腦袋里,而她需要專程到學(xué)校去獲得這些知識(shí),因?yàn)槟鞘钱?dāng)時(shí)學(xué)習(xí)的途徑 快進(jìn)過(guò)一代: 這是個(gè)只有一間教室的學(xué)校,Oak Grove,我父親就是在這間只有一個(gè)教室的學(xué)校就讀。而同樣的,他不得不去上學(xué) 以從老師那兒取得知識(shí),然后將這些知識(shí)儲(chǔ)存在他唯一的移動(dòng)內(nèi)存,那就是他自己的腦袋里,然后將這些隨身攜帶,因?yàn)檫@是過(guò)去知識(shí)被傳遞的方式 從老師傳給學(xué)生,接著在世界上使用。當(dāng)我還小的時(shí)候,我們家里有一套百科全書。從我一出生就買了這套書,而那是非常了不起的事情,因?yàn)槲也恍枰戎D書館取得這些知識(shí),這些信息就在我的屋子里 而那真是太棒了。這是 和過(guò)去相比,是非常不同的 這改變了我和信息互動(dòng)的方式 即便改變的幅度很小。但這些知識(shí)卻離我更近了。我可以隨時(shí)獲取它們。
1:34
在過(guò)去的這幾年間 從我還在念高中 到我開始教書的時(shí)候,我們真的親眼目睹網(wǎng)絡(luò)的發(fā)展。就在網(wǎng)絡(luò)開始 作為教學(xué)用的工具發(fā)展的時(shí)候,我離開威斯康辛州 搬到勘薩斯州,一個(gè)叫勘薩斯的小鎮(zhèn) 在那里我有機(jī)會(huì) 在一個(gè)小而美麗的勘薩斯的鄉(xiāng)村學(xué)區(qū) 教書,教我最喜歡的學(xué)科 “美國(guó)政府” 那是我教書的第一年,充滿熱情,準(zhǔn)備教“美國(guó)政府” 我當(dāng)時(shí)熱愛教政治體系。這些十二年級(jí)的孩子 對(duì)于美國(guó)政府體系 并不完全充滿熱情。開始教書的第二年,我學(xué)到了一些事情,讓我改變了教學(xué)方針。我提供他們一個(gè)真實(shí)體驗(yàn)的機(jī)會(huì) 讓他們可以自主學(xué)習(xí)。我沒(méi)有告訴他們得做什么,或是要怎么做。我只是在他們面前提出一個(gè)問(wèn)題,要他們?cè)谧约旱纳鐓^(qū)設(shè)立一個(gè)選舉論壇。
2:27
他們散布傳單,聯(lián)絡(luò)各個(gè)選舉辦公室,他們和秘書排定行程,他們?cè)O(shè)計(jì)了一本選舉論壇手冊(cè) 提供給全鎮(zhèn)的鎮(zhèn)民讓他們更了解這些候選人。他們邀請(qǐng)所有的人到學(xué)校 參與晚上的座談 談?wù)撜驼?還有鎮(zhèn)里的每條街是不是都修建完善,學(xué)生們真的得到強(qiáng)大的體驗(yàn)式學(xué)習(xí)。學(xué)校里比較資深年長(zhǎng)的老師 看著我說(shuō) “喔,看她,多天真呀,竟想試著這么做。”(大笑)“她不知道她把自己陷入怎么樣的局面” 但我知道孩子們會(huì)出席 而我真的這樣相信。每個(gè)禮拜我都對(duì)他們說(shuō)我是如何期待他們的表現(xiàn)。而那天晚上,全部九十個(gè)孩子 每個(gè)人的穿戴整齊,各司其職,完全掌握論壇 我只需要坐在一旁看著。那是屬于他們的夜晚,那是經(jīng)驗(yàn),那是實(shí)在的經(jīng)驗(yàn)。那對(duì)他們來(lái)說(shuō)具有意義。而他們將會(huì)更加努力。
3:17
離開堪薩斯后,我搬到美麗的亞利桑納州,我在Flagstaff小鎮(zhèn)教了幾年書,這次是教初中的學(xué)生。幸運(yùn)的,我這次不用教美國(guó)政治。這次我教的是更令人興奮的地理。再一次,非常期待的要學(xué)習(xí)。但有趣的是 我發(fā)現(xiàn)在這個(gè)亞歷桑納州的教職 我所面對(duì)的 是一群非常多樣化的,彼此之間差異懸殊的孩子們 在一所真正的公立學(xué)校。在那里,有些時(shí)候,我們會(huì)得到了一些機(jī)會(huì)。其中一個(gè)機(jī)會(huì)是 我們得以和Paul Russabagina見面,這位先生 正是電影“盧安達(dá)飯店”根據(jù)描述的那位主人翁 他當(dāng)時(shí)正要到隔壁的高中演講 我們可以步行到那所學(xué)校,我們甚至不用坐公共汽車 完全不需要額外的支出,非常完美的校外教學(xué)
4:04
然后接著的問(wèn)題是 你要怎么和七八年級(jí)的學(xué)生談?wù)摲N族屠殺 用怎么樣的方式來(lái)處理這個(gè)問(wèn)題 才是一種負(fù)責(zé)任和尊重的方式,讓學(xué)生們知道該怎么面對(duì)這個(gè)問(wèn)題。所以我們決定去觀察PaulRusesabagina是怎么做的 把他當(dāng)作一個(gè)例子 一個(gè)平凡人如何利用自己的生命做些積極的事情的例子。接著,我挑戰(zhàn)這些孩子,要他們?nèi)フ页?在他們的生命里,在他們自己的故事中,或是在他們自己的世界里,找出那些他們認(rèn)為也做過(guò)類似事情的人。我要他們?yōu)檫@些人和事跡制作一部短片。這是我們第一次嘗試制作短片。沒(méi)有人真的知道如何利用電腦制作短片。但他們非常投入,我要他們?cè)谄永镉米约旱穆曇簟D菍?shí)在是最棒的啟發(fā)方式 當(dāng)你要孩子們用他們自己的聲音 當(dāng)你要他們?yōu)樽约赫f(shuō)話,說(shuō)那些他們?cè)敢夥窒淼墓适隆_@項(xiàng)作業(yè)的最后一個(gè)問(wèn)題是 你打算怎么利用你自己的生命 去正面的影響其他人 孩子們說(shuō)出來(lái)的那些話 在你詢問(wèn)他們后并花時(shí)間傾聽那些話后 是非常了不起的。
5:05
快進(jìn)到賓州,我現(xiàn)在住的地方。我在科學(xué)領(lǐng)導(dǎo)學(xué)院教書,它是富蘭克林學(xué)院 和費(fèi)城學(xué)區(qū)協(xié)同的合辦的。我們是一間9年級(jí)到12年級(jí)的公立高中,但我們的教學(xué)方式很不一樣。我起初搬到那里 是為了親身參與一個(gè)教學(xué)環(huán)境 一個(gè)可以證實(shí)我所理解孩子可以有效學(xué)習(xí)方式的方式,一個(gè)愿意探索 所有可能性的教學(xué)環(huán)境 當(dāng)你愿意放棄 一些過(guò)去的標(biāo)準(zhǔn)模式,放棄我祖母和我父親上學(xué)的那個(gè)年代 甚至是我自己念書的那個(gè)年代,因?yàn)樾畔⒌南∪保揭粋€(gè)我們正處于信息過(guò)剩的時(shí)代。所以你該怎么處理那些環(huán)繞在四周的知識(shí)? 你為什么要孩子們來(lái)學(xué)校? 如果他們?cè)僖膊恍枰匾獾綄W(xué)校獲得這些知識(shí)?
5:51
在賓州,我們有一個(gè)人人有筆記本的項(xiàng)目,所以這些孩子每天帶著他們筆記本電腦,帶著電腦回家,隨時(shí)學(xué)習(xí)知識(shí)。有一件事你需要學(xué)著適應(yīng)的是 當(dāng)你給了學(xué)生工具 讓他們可以自主取得知識(shí),你得適應(yīng)一個(gè)想法 那就是允許孩子失敗 把失敗視為學(xué)習(xí)的一部分。我們現(xiàn)在面對(duì)教育大環(huán)境 帶著一種 迷戀單一解答的文化 一種靠選擇題折優(yōu)的文化,而我在這里要告訴你們,這不是學(xué)習(xí)。這絕對(duì)是個(gè)錯(cuò)誤 去要求孩子們永遠(yuǎn)不可以犯錯(cuò)。要求他們永遠(yuǎn)都要有正確的解答 而不允許他們?nèi)W(xué)習(xí)。所以我們實(shí)施了這個(gè)項(xiàng)目,這就是這個(gè)項(xiàng)目中一件作品。我?guī)缀鯊膩?lái)沒(méi)有展示過(guò)這些 因?yàn)槲覀儗?duì)于錯(cuò)誤與失敗的觀念。
6:45
我的學(xué)生們制作了這些信息圖表 結(jié)果是我們決定以這個(gè)匯報(bào)作為我們學(xué)年的總結(jié)報(bào)告 內(nèi)容是回應(yīng)漏油事件。我要求他們拿 他們看過(guò)的資訊圖表當(dāng)做范例 就是在媒體里展示的那些信息圖表,仔細(xì)看看那里頭什么是有趣的,然后自己設(shè)計(jì)一個(gè) 以美國(guó)歷史中其他的人為災(zāi)難為主題。我為這項(xiàng)作業(yè)設(shè)了一些其他的條件 他們覺(jué)得這個(gè)作業(yè)有些困難,因?yàn)槲覀儚膩?lái)沒(méi)有出過(guò)這樣的作業(yè),而他們不完全知道要怎么進(jìn)行。他們可以談?wù)撨@議題,相當(dāng)順暢,他們也能寫得非常非常得好,但當(dāng)被要求要用一種其他的方式來(lái)表達(dá)想法的時(shí)候 他們有點(diǎn)無(wú)所適從。但我給了他們空間去做這個(gè)作業(yè)。去創(chuàng)造,去自己發(fā)現(xiàn)該怎么做。讓我們拭目以待我們可以完成些什么。最后那些總是 呈現(xiàn)最佳視覺(jué)效果作品的學(xué)生,這次也沒(méi)有讓人失望 這個(gè)作品大概花了兩三天的時(shí)間 而這是來(lái)自一個(gè)經(jīng)常很棒得完成作業(yè)的學(xué)生。
7:39
然后當(dāng)我要所有學(xué)生坐下來(lái),我問(wèn)他們“誰(shuí)交出了最好的作品?” 他們立刻指著這個(gè)作品回答“這件” 他們并沒(méi)有細(xì)讀其中的內(nèi)容,就回答了“這件” 然后我說(shuō),“那么,是什么因素讓這個(gè)作品這么好?” 他們回答說(shuō),“喔,設(shè)計(jì)得很好,他用了很好的顏色組合,還有一些...” 他們分別說(shuō)了想法,我們一起討論了之后 我說(shuō),“現(xiàn)在去讀讀內(nèi)容” 接著他們說(shuō)“喔,現(xiàn)在看起來(lái)好像其實(shí)沒(méi)有那么好” 后來(lái)我們談到另外一個(gè)作業(yè)--那個(gè)作品沒(méi)有很好的視覺(jué)設(shè)計(jì),但是有非常好的資訊內(nèi)容--我們接著花了大概一個(gè)小時(shí)來(lái)討論這個(gè)學(xué)習(xí)過(guò)程,因?yàn)槟遣⒉皇顷P(guān)于哪個(gè)作品比較完美,或是我能或不能創(chuàng)造出這樣的東西; 這作業(yè)是要他們?yōu)樽约簞?chuàng)作。這作業(yè)也讓他們有失敗的可能,消化思考之后,從失敗中學(xué)習(xí)。今年,當(dāng)我們又再一次嘗試類似的作業(yè),他們都將會(huì)比去年做的更好。因?yàn)閷W(xué)習(xí)必須包含一定程度的失敗,因?yàn)槭【哂薪虒W(xué)意義 在學(xué)習(xí)的過(guò)程中。
8:29
我有上百萬(wàn)個(gè)照片 可以展示,可我得小心的選擇--好,這是我最喜歡的一張--學(xué)生正在學(xué)習(xí)的照片,學(xué)習(xí)可以是什么樣子 在一個(gè)我們放棄傳統(tǒng)觀念的環(huán)境中 學(xué)生非得來(lái)學(xué)校以獲得知識(shí)這樣的想法,取而代之,問(wèn)他們,他們可以利用這些知識(shí)來(lái)做些什么? 問(wèn)他們真正有趣的問(wèn)題。他們不會(huì)讓人失望。要求他們?nèi)ゲ煌牡胤剑ビH眼見識(shí)不同的事情,去真正的體驗(yàn)學(xué)習(xí),去玩,去查詢。這是我最喜歡的照片之一 因?yàn)檫@是一張星期二照的照片,當(dāng)我要求學(xué)生們?nèi)ネ镀薄_@是Robbie,這是他第一次投票,而他想要和大家分享這個(gè)投票的經(jīng)歷。但這也是學(xué)習(xí),因?yàn)槲覀円麄兊酵忸^真實(shí)的世界去。
9:20
重點(diǎn)是 如果我們繼續(xù)把教育 當(dāng)作是要來(lái)學(xué)校 取得知識(shí) 而不是體驗(yàn)學(xué)習(xí)的過(guò)程,傾聽學(xué)生的聲音,接納錯(cuò)誤和失敗,我們將會(huì)誤解上學(xué)的意義。而今天每個(gè)人在談?wù)摰拿考虑?都將不可能達(dá)成,如果我們繼續(xù)這樣的教育系統(tǒng) 而不重視這些價(jià)值,因?yàn)槲覀兪遣豢赡芤揽繕?biāo)準(zhǔn)化測(cè)試,一種只有一個(gè)標(biāo)準(zhǔn)答案的文化是沒(méi)有辦法引領(lǐng)我們達(dá)到目標(biāo)的。我們知道怎么樣可以做得更好,而現(xiàn)在,需要做得更好的時(shí)刻到了。
第二篇:TED 演講稿 怎樣從錯(cuò)誤中學(xué)習(xí)
I have been teaching for a long time, and in doing so have acquired a body of knowledge about kids and learning that I really wish more people would understand about the potential of students.In 1931, my grandmother--bottom left for you guys over here--graduated from the eighth grade.She went to school to get the information because that's where the information lived.It was in the books;it was inside the teacher's head;and she needed to go there to get the information, because that's how you learned.Fast-forward a generation: this is the one-room schoolhouse, Oak Grove, where my father went to a one-room schoolhouse.And he again had to travel to the school to get the information from the teacher, stored it in the only portable memory he has, which is inside his own head, and take it with him, because that is how information was being transported from teacher to student and then used in the world.When I was a kid, we had a set of encyclopedias at my house.It was purchased the year I was born, and it was extraordinary, because I did not have to wait to go to the library to get to the information.The information was inside my house and it was awesome.This was differentthan either generation had experienced before, and it changed the way I interacted with information even at just a small level.But the information was closer to me.I could get access to it.In the time that passes between when I was a kid in high school and when I started teaching,we really see the advent of the Internet.Right about the time that the Internet gets going as an educational tool, I take off from Wisconsin and move to Kansas, small town Kansas, where I had an opportunity to teach in a lovely, small-town, rural Kansas school district, where I was teaching my favorite subject, American government.My first year--super gung-ho--going to teach American government, loved the political system.Kids in the 12th grade: not exactly all that enthusiastic about the American government system.Year two: learned a few things--had to change my tactic.And I put in front of them an authentic experience that allowed them to learn for themselves.I didn't tell them what to do or how to do it.I posed a problem in front of them, which was to put on an election forum for their own community.They produced fliers.They called offices.They checked schedules.They were meeting with secretaries.They produced an election forum booklet for the entire town to learn more about their candidates.They invited everyone into the school for an evening of conversation about government and politics and whether or not the streets were done well, and really had this robust experiential learning.The older teachers--more experienced--looked at me and went, “Oh, there she is.That's so cute.She's trying to get that done.”(Laughter)“She doesn't know what she's in for.” But I knew that the kids would show up, and I believed it, and I told them every week what I expected out of them.And that night, all 90 kids--dressed appropriately, doing their job, owning it.I had to just sit and watch.It was theirs.It was experiential.It was authentic.It meant something to them.And they will step up.From Kansas, I moved on to lovely Arizona, where I taught in Flagstaff for a number of years,this time with middle school students.Luckily, I didn't have to teach them American government.Could teach them the more exciting topic of geography.Again, “thrilled” to learn.But what was interesting about this position I found myself in in Arizona, was I had this reallyextraordinarily eclectic group of kids to work with in a truly public school, and we got to have these moments where we would get these opportunities.And one opportunity was we got to go and meet Paul Rusesabagina, which is the gentleman that the movie “Hotel Rwanda” is based after.And he was going to speak at the high school next door to us.We could walk there.We didn't even have to pay for the buses.There was no expense cost.Perfect field trip.The problem then becomes how do you take seventh-and eighth-graders to a talk about genocide and deal with the subject in a way that is responsible and respectful, and they know what to do with it.And so we chose to look at Paul Rusesabagina as an example of a gentleman who singularly used his life to do something positive.I then challenged the kids to identify someone in their own life, or in their own story, or in their own world, that they could identify that had done a similar thing.I asked them to produce a little movie about it.It's the first time we'd done this.Nobody really knew how to make these little movies on the computer, but they were into it.And I asked them to put their own voice over it.It was the most awesome moment of revelation that when you ask kids to use their own voice and ask them to speak for themselves, what they're willing to share.The last question of the assignment is: how do you plan to use your life to positively impact other people? The things that kids will say when you ask them and take the time to listen is extraordinary.Fast-forward to Pennsylvania, where I find myself today.I teach at the Science Leadership Academy, which is a partnership school between the Franklin Institute and the school district of Philadelphia.We are a nine through 12 public school, but we do school quite differently.I moved there primarily to be part of a learning environment that validated the way that I knew that kids learned, and that really wanted to investigate what was possible when you are willing to let go of some of the paradigms of the past, of information scarcity when my grandmother was in school and when my father was in school and even when I was in school,and to a moment when we have information surplus.So what do you do when the information is all around you? Why do you have kids come to school if they no longer have to come there to get the information? In Philadelphia we have a one-to-one laptop program, so the kids are bringing in laptops with them everyday, taking them home, getting access to information.And here's the thing that you need to get comfortable with when you've given the tool to acquire information to students, is that you have to be comfortable with this idea of allowing kids to fail as part of the learning process.We deal right now in the educational landscape with an infatuation with the culture of one right answer that can be properly bubbled on the average multiple choice test, and I am here to share with you: it is not learning.That is the absolute wrong thing to ask, to tell kids to never be wrong.To ask them to always have the right answer doesn't allow them to learn.So we did this project, and this is one of the artifacts of the project.I almost never show them off because of the issue of the idea of failure.My students produced these info-graphics as a result of a unit that we decided to do at the end of the year responding to the oil spill.I asked them to take the examples that we were seeing of the info-graphics that existed in a lot of mass media, and take a look at what were the interesting components of it, and produce one for themselves of a different man-made disaster from American history.And they had certain criteria to do it.They were a little uncomfortable with it, because we'd never done this before, and they didn't know exactly how to do it.They can talk--they're very smooth, and they can write very, very well, but asking them to communicate ideas in a different way was a little uncomfortable for them.But I gave them the room to just do the thing.Go create.Go figure it out.Let's see what we can do.And the student that persistently turns out the best visual product did not disappoint.This was done in like two or three days.And this is the work of the student that consistently did it.And when I sat the students down, I said, “Who's got the best one?” And they immediately went, “There it is.” Didn't read anything.“There it is.” And I said, “Well what makes it great?”And they're like, “Oh, the design's good, and he's using good color.And there's some...” And they went through all that we processed out loud.And I said, “Go read it.” And they're like, “Oh, that one wasn't so awesome.” And then we went to another one--it didn't have great visuals, but it had great information--and spent an hour talking about the learning process,because it wasn't about whether or not it was perfect, or whether or not it was what I could create.It asked them to create for themselves, and it allowed them to fail, process, learn from.And when we do another round of this in my class this year, they will do better this time,because learning has to include an amount of failure, because failure is instructional in the process.There are a million pictures that I could click through here, and had to choose carefully--this is one of my favorites--of students learning, of what learning can look like in a landscape where we let go of the idea that kids have to come to school to get the information, but instead, ask them what they can do with it.Ask them really interesting questions.They will not disappoint.Ask them to go to places, to see things for themselves, to actually experience the learning, to play, to inquire.This is one of my favorite photos, because this was taken on Tuesday, when I asked the students to go to the polls.This is Robbie, and this was his first day of voting, and he wanted to share that with everybody and do that.But this is learning too, because we asked them to go out into real spaces.The main point is that, if we continue to look at education as if it's about coming to school to get the information and not about experiential learning, empowering student voice and embracing failure, we're missing the mark.And everything that everybody is talking about today isn't possible if we keep having an educational system that does not value these qualities, because we won't get there with a standardized test, and we won't get there with a culture of one right answer.We know how to do this better, and it's time to do better.

https://kouyumao.com 從TED演講中學(xué)習(xí)技巧,商務(wù)人士用得著!
觀看TED演講成了許多人學(xué)習(xí)、娛樂(lè)的一部分生活日常,當(dāng)然大量的TED演講視頻也是英語(yǔ)學(xué)習(xí)者可以好好利用的資源之一。其實(shí),它的作用深挖掘遠(yuǎn)不止于此。TED作為一種受眾眾多、全球流行的想法分享展示平臺(tái)與講演形式,其經(jīng)過(guò)排練達(dá)到的高水準(zhǔn)演講水平、3-18分鐘內(nèi)用最動(dòng)人的方式傳達(dá)內(nèi)容的精華濃縮、全舞臺(tái)式的演講呈現(xiàn)與觀眾注意,都使之值得每一位演講者借鑒。以下TED演講技巧,送給那些需要公開場(chǎng)合陳述、向受眾展示內(nèi)容方案以及與人日常交流推銷的商務(wù)人士。
1.用故事或個(gè)人感受/經(jīng)歷開頭。這樣的開頭陳述方式貼合生活實(shí)際,能很好地吸引觀眾的注意力與興趣點(diǎn),并且可以使演講者在一開始就達(dá)到自信控場(chǎng)的效果。相比于枯燥的一上來(lái)就開始陳述,這樣的開頭方式能讓在場(chǎng)所有人精神為之一振、專注聆聽你接下來(lái)的話。
2.通過(guò)個(gè)人感受或者故事,設(shè)定一個(gè)疑問(wèn)。這個(gè)疑問(wèn)必須針對(duì)你講話的主題主旨。比如說(shuō),介紹推銷一款產(chǎn)品,就問(wèn)某個(gè)痛點(diǎn)怎么樣解決?呈現(xiàn)一個(gè)策劃方案,就問(wèn)為什么消費(fèi)者(自己)
口語(yǔ)貓英語(yǔ) · 在家上外教課
https://kouyumao.com 沒(méi)有被吸引?講到這里,觀眾已經(jīng)被帶入到他提前設(shè)定好的一個(gè)
疑問(wèn)中,相信很多人都想知道,Why?接下環(huán)節(jié)的觀點(diǎn)陳述或者介紹,講我們的產(chǎn)品特性是如何滿足用戶需要的;這個(gè)策劃方案的優(yōu)勢(shì)在哪里。觀眾一定認(rèn)真接受并思考,從而使你的話給受眾留下深刻印象。
3.話語(yǔ)簡(jiǎn)潔精煉,并在事前模擬排練。啰嗦的長(zhǎng)篇大論會(huì)造成表達(dá)不清晰、觀眾也排斥。為了達(dá)到簡(jiǎn)潔表達(dá)的效果,最好事先打好腹稿,去掉不必要的重復(fù)的話。如果可以的話,進(jìn)行事前的模擬排練,不僅可以更好地掌控邏輯和時(shí)間節(jié)奏,還能增加呈現(xiàn)時(shí)的自信優(yōu)秀感,給人留下良好印象。
職場(chǎng)少不了溝通表達(dá),以上TED演講技巧,你學(xué)到了嗎?不妨下次嘗試一下!

第五篇:Ted演講
Ralph Langner談21世紀(jì)電子武器Stuxnet揭密
關(guān)于這場(chǎng)演講
Stuxnet計(jì)算機(jī)蠕蟲于2010年首次被發(fā)現(xiàn),帶來(lái)了令人費(fèi)解的謎團(tuán)。除了它不尋常且高度復(fù)雜的編碼以外,還隱藏著一個(gè)更令人不安的謎團(tuán):它的攻擊目標(biāo)。Ralph Langner及其團(tuán)隊(duì)協(xié)助破解Stuxnet編碼,找出這個(gè)數(shù)字彈頭的最終攻擊目標(biāo)-以及其幕后源頭。經(jīng)使用計(jì)算機(jī)數(shù)字鑒識(shí)方法深入檢視后,他解釋了其運(yùn)作原理。
關(guān)于Ralph Langner
Ralph Langner是德國(guó)控制系統(tǒng)的安全顧問(wèn)。他對(duì)Stuxnet惡意軟件的分析受到全球矚目。
為什么要聽他演講
Ralph Langner為獨(dú)立網(wǎng)絡(luò)安全公司Langner的領(lǐng)導(dǎo)者,專營(yíng)控制系統(tǒng)-監(jiān)控和調(diào)控其它設(shè)備的電子裝置,如生產(chǎn)設(shè)備。這些裝置與運(yùn)作我們城市和國(guó)家的基礎(chǔ)設(shè)施有密切關(guān)系,這使它們逐漸成為一場(chǎng)新興且具高度復(fù)雜型態(tài)的電子戰(zhàn)爭(zhēng)攻擊目標(biāo)。自2010年起,當(dāng)Stuxnet計(jì)算機(jī)蠕蟲首次現(xiàn)身時(shí),Langner堅(jiān)決地投身于這個(gè)戰(zhàn)場(chǎng)。
身為致力于譯碼這個(gè)神秘程序的一份子,Langner和他的團(tuán)隊(duì)分析Stuxnet的數(shù)據(jù)結(jié)構(gòu),并找出他認(rèn)為其最終的攻擊目標(biāo):運(yùn)行于核工廠離心機(jī)的控制系統(tǒng)軟件-特別是伊朗的核工廠。Langner進(jìn)一步分析,發(fā)現(xiàn)Stuxnet可能的幕后源頭,并于TED2011演講中透露這個(gè)秘密。

已有中譯字幕的TED影片目錄(繁體)(簡(jiǎn)體)。請(qǐng)注意繁簡(jiǎn)目錄是不一樣的。
Ralph Langner談21世紀(jì)電子武器Stuxnet揭密
Stuxnet計(jì)算機(jī)蠕蟲背后的想法其實(shí)很簡(jiǎn)單,我們不希望伊朗造出原子彈,他們發(fā)展核武器的主要資產(chǎn)是納坦茲的濃縮鈾工廠,你們看到的灰色方塊是實(shí)時(shí)控制系統(tǒng),現(xiàn)在,如果我們?cè)O(shè)法破壞控制速度和閥門的驅(qū)動(dòng)系統(tǒng),我們事實(shí)上可以使離心機(jī)產(chǎn)生很多問(wèn)題。這些灰色方塊無(wú)法執(zhí)行Windows軟件,兩者是完全不同的技術(shù),但如果我們?cè)O(shè)法將一個(gè)有效的Windows病毒放進(jìn)一臺(tái)筆記本電腦里,由一位機(jī)械工程師操作,設(shè)定這個(gè)灰色方塊,那么我們就可以著手進(jìn)行了,這就是Stuxnet大致背景。
因此,我們從Windows釋放程序開始,讓病毒載體進(jìn)入灰色方塊中,破壞離心機(jī),延遲伊朗的核計(jì)劃,任務(wù)完成,很簡(jiǎn)單,對(duì)吧?我想說(shuō)明我們是如何發(fā)現(xiàn)這個(gè)的,當(dāng)我們?cè)诎肽昵伴_始研究Stuxnet時(shí),對(duì)這個(gè)東西的攻擊目標(biāo)一無(wú)所知,唯一了解的是它在Windows的部份非常、非常復(fù)雜,釋放程序部份使用多個(gè)零日漏洞,它似乎想要做些什么,用這些灰色方塊,這些實(shí)時(shí)控制系統(tǒng),因此,這引起我們的注意,我們開始了一個(gè)實(shí)驗(yàn)計(jì)劃,我們用Stuxnet感染我們的系統(tǒng)并審視結(jié)果,然后一些非常有趣的事發(fā)生了。Stuxnet表現(xiàn)得像只白老鼠,不喜歡我們的奶酪,聞一聞,但不想吃。這根本沒(méi)道里。之后,我們用不同口味的奶酪進(jìn)行實(shí)驗(yàn),我意識(shí)到,哦,這是一個(gè)直接攻擊,完全直接的。釋放程序在這些灰
色方塊中有效的潛伏著,如果它發(fā)現(xiàn)了一個(gè)特定程序組態(tài),甚至是它正試圖感染的程序,它都會(huì)確實(shí)針對(duì)這個(gè)目標(biāo)執(zhí)行,如果沒(méi)發(fā)現(xiàn),Stuxnet就不起作用。
所以這真的引起了我的注意,我們開始進(jìn)行這方面的工作,幾乎日以繼夜,因?yàn)槲蚁耄冒桑覀儾恢浪哪繕?biāo)是什么,很可能的,比方說(shuō)美國(guó)的發(fā)電廠,或德國(guó)的化工廠,所以我們最好盡快找出目標(biāo)。因此,我們抽出攻擊代碼并進(jìn)行反編譯,我們發(fā)現(xiàn)它的結(jié)構(gòu)由兩個(gè)數(shù)字炸彈組成,一個(gè)較小、一個(gè)較大。我們也看到,這是非常專業(yè)的設(shè)計(jì),由顯然知道所有內(nèi)幕信息的人編寫,他們知道所有必需攻擊的位和字節(jié),搞不好他們還知道控制員的鞋子尺寸,因此他們什么都知道。
如果你曾聽過(guò)Stuxnet的釋放程序,是復(fù)雜、高科技的,讓我跟你們說(shuō)明一下。病毒本身是很高科技沒(méi)錯(cuò),比我們?cè)娺^(guò)的任何編碼都高深,這是這個(gè)實(shí)際攻擊代碼的樣本,我們談?wù)摰氖谴蟾?5,000行的代碼,看起來(lái)很像舊式的匯編語(yǔ)言。我想告訴你們的是,我們?nèi)绾文軌蚶斫膺@段代碼,所以,我們首先要尋找的是系統(tǒng)的函數(shù)調(diào)用,因?yàn)槲覀冎浪鼈兊淖饔檬鞘裁础?/p>
然后,我們尋找時(shí)間控制器和數(shù)據(jù)結(jié)構(gòu),試圖將其與真實(shí)世界連結(jié)起來(lái),尋找現(xiàn)實(shí)世界中的潛在目標(biāo),因此我們必需進(jìn)行目標(biāo)推測(cè),以便確認(rèn)或排除。為了找到推測(cè)目標(biāo),我們想到,它必定具有絕對(duì)破壞性,必定是一個(gè)高價(jià)值目標(biāo),最可能設(shè)置在伊朗,因?yàn)檫@是大部份感染發(fā)生的地點(diǎn)。在這區(qū)域內(nèi)你不會(huì)找到幾千個(gè)目標(biāo),基本上范圍可以縮小為布什爾核電廠及納坦茲濃縮鈾工廠。
所以我告訴我的助手,“列出我們客戶中所有離心機(jī)和核電廠專家的名單”,我打電話給他們,聽取他們的意見,努力用我們?cè)诖a和數(shù)據(jù)中的發(fā)現(xiàn)與他們的專業(yè)知識(shí)做對(duì)照。這很有效,因此,我們找出了這個(gè)小數(shù)字彈頭與轉(zhuǎn)子控制的關(guān)聯(lián),轉(zhuǎn)子是離心機(jī)內(nèi)部的運(yùn)轉(zhuǎn)零件,就是你們看到的這個(gè)黑色物體,如果控制這個(gè)轉(zhuǎn)子的速度,事實(shí)上你就能使轉(zhuǎn)子損壞,甚至最后使離心機(jī)爆炸。我們也看到了這次攻擊的目標(biāo),實(shí)際上進(jìn)行的相當(dāng)緩慢、低調(diào),顯然為了達(dá)成目標(biāo),快把維修工程師逼瘋了,因?yàn)樗麄儫o(wú)法迅速找出答案。
這個(gè)大數(shù)字彈頭-我們做過(guò)嘗試,非常仔細(xì)檢查數(shù)據(jù)和數(shù)據(jù)結(jié)構(gòu),因此,例如數(shù)字164在這些代碼中確實(shí)很突出,你不能忽視它。我開始研究科學(xué)文獻(xiàn),這些離心機(jī)如何在納坦茲組建,并找出它們的結(jié)構(gòu),就是所謂的層級(jí)。每個(gè)層級(jí)由164臺(tái)離心機(jī)組成,這就說(shuō)的通了,與我們的結(jié)果匹配。
而它甚至更有幫助。這些在伊朗的離心機(jī)細(xì)分為15種所謂的等級(jí),你猜我們?cè)诠舸a中發(fā)現(xiàn)什么?一個(gè)幾乎相同的結(jié)構(gòu)。所以,同樣的,這與結(jié)果完美匹配,就我們所尋找的東西來(lái)說(shuō),這給了我們相當(dāng)大的信心。別誤解我的意思,不是像這樣彈指之間,為了獲致這些成果,歷經(jīng)幾星期相當(dāng)艱苦的奮斗,我們常常走進(jìn)死胡同,必需重新來(lái)過(guò)。
總之,我們找到了這兩個(gè)數(shù)字彈頭,實(shí)際上是針對(duì)同一個(gè)目標(biāo),但從不同角度。小彈頭對(duì)準(zhǔn)一個(gè)層級(jí),讓轉(zhuǎn)子加速旋轉(zhuǎn)然后急遽減速,而大彈頭影響六個(gè)層級(jí)并操縱閥門,總之,我們非常有信心,我們已經(jīng)確認(rèn)目標(biāo)是什么,是納坦茲,就只有納坦茲。因此,我們不必?fù)?dān)心其它目標(biāo)可能被Stuxnet攻擊。
我們看到一些非常酷的東西,真的讓我印象深刻。下方是灰色方塊,頂端你們看到的是離心機(jī),這些東西所做的是攔截來(lái)自傳感器的輸入值,例如,來(lái)自壓力傳感器和振動(dòng)傳感器的,它提供正常代碼,在攻擊中依然執(zhí)行,用的是假的輸入數(shù)
據(jù)。事實(shí)上,這個(gè)假的輸入數(shù)據(jù)是Stuxnet事先錄制的,因此,這就像來(lái)自好萊塢電影的搶劫過(guò)程中,監(jiān)視器被放入預(yù)錄的影片,酷吧?
這里的想法顯然不僅是愚弄控制室中的操作者,實(shí)際上更加危險(xiǎn)且更具攻擊性,這個(gè)想法是規(guī)避數(shù)字安全系統(tǒng)。我們需要數(shù)字安全系統(tǒng),當(dāng)一位人類操作員的行動(dòng)不夠快時(shí),因此,例如在一座核電廠中,當(dāng)一臺(tái)大蒸汽渦輪機(jī)嚴(yán)重超速時(shí),你必須在一毫秒內(nèi)打開泄壓閥。顯然,一位人類操作員辦不到,因此,這就是我們需要使用數(shù)字安全系統(tǒng)之處。當(dāng)它們被破壞,真正糟糕的事就會(huì)發(fā)生了,你的工廠會(huì)爆炸,無(wú)論你的操作員或安全系統(tǒng)都無(wú)法注意到這一點(diǎn),這很可怕。
但還會(huì)更糟。我要說(shuō)的這些相當(dāng)重要,想想看,這種攻擊是一般性的,它沒(méi)什么特定性,對(duì)離心機(jī)來(lái)說(shuō),還有濃縮鈾,因此,它也會(huì)作用于,例如一座核電廠或一座汽車工廠,它是通用的,你不需要-身為攻擊者,你不需要藉由USB裝置傳遞這個(gè)病毒載體,如我們?cè)赟tuxnet例子中看到的,你也可以使用傳統(tǒng)的蠕蟲病毒技術(shù)的來(lái)散播,盡可能傳播四方。如果你這么做,最終它會(huì)變成具大規(guī)模破壞性的網(wǎng)絡(luò)武器,這是我們必然會(huì)面臨的后果。所以,不幸的是,這種攻擊最大量的目標(biāo)并不是在中東,而是在美國(guó)、歐洲和日本。因此,所有這些綠色區(qū)域就是遭受最多攻擊的目標(biāo),我們必須面對(duì)這個(gè)后果,我們最好現(xiàn)在開始做準(zhǔn)備。
謝謝。
(掌聲)
Chris Anderson:我有個(gè)問(wèn)題,Ralph,這件事已廣為人知,人們認(rèn)為摩薩德(以色列情報(bào)機(jī)構(gòu))是幕后的主要推手,你也這么認(rèn)為嗎?
Ralph Langner:好,你真的想知道嗎?
Chris Anderson:是啊!
Ralph Langner:好,我的看法是,摩薩德有參與,但以色列并非領(lǐng)導(dǎo)勢(shì)力。因此,背后的主導(dǎo)力量是網(wǎng)絡(luò)超級(jí)大國(guó),只有一個(gè),就是美國(guó)。幸好、幸好,因?yàn)槿绻皇沁@樣,我們的問(wèn)題可能更大。
CA:謝謝你嚇壞了美國(guó)人,謝謝Ralph。
