在線教學(xué)掀起教育革命風(fēng)暴

在線課程掀起高等教育革命

LORD knows there’s a lot of bad news in the world today to get you down, but there is one big thing happening that leaves me incredibly hopeful about the future, and that is the budding revolution in global online higher education. Nothing has more potential to lift more people out of poverty — by providing them an affordable education to get a job or improve in the job they have. Nothing has more potential to unlock a billion more brains to solve the world’s biggest problems. And nothing has more potential to enable us to reimagine higher education than the massive open online course, or MOOC, platforms that are being developed by the likes of Stanford and the Massachusetts Institute of Technology and companies like Coursera and Udacity.

上帝知道，在今日的世界，有多少壞消息讓人沮喪，不過(guò)，有一件正在發(fā)生的大事讓我對(duì)未來(lái)滿懷希望，那就是在全球范圍內(nèi)正蓬勃興起的網(wǎng)絡(luò)高等教育革 命。沒(méi)有哪樣事物有這么大的潛力，能去消滅貧困，方法就是通過(guò)給窮人提供負(fù)擔(dān)得起的教育來(lái)讓他們獲得一份工作、或改善他們現(xiàn)有的工作。沒(méi)有哪樣事物有這么 大的潛力，能解放十多億的頭腦來(lái)解決世界上最艱巨的問(wèn)題。沒(méi)有哪樣事物有這么大的潛力，能讓我們重新構(gòu)想高等教育，而我說(shuō)的就是大型公開在線課程 (massive open online course，簡(jiǎn)稱MOOC)，這類高等教育平臺(tái)正在由斯坦福大學(xué)(Stanford)、麻省理工學(xué)院(Massachusetts Institute of Technology)等大學(xué)和Coursera以及Udacity等公司進(jìn)行開發(fā)。

Last May I wrote about Coursera — co-founded by the Stanford computer scientists Daphne Koller and Andrew Ng — just after it opened. Two weeks ago, I went back out to Palo Alto to check in on them. When I visited last May, about 300,000 people were taking 38 courses taught by Stanford professors and a few other elite universities. Today, they have 2.4 million students, taking 214 courses from 33 universities, including eight international ones.

去年5月，我在Coursera剛剛上線時(shí)寫了一篇關(guān)于它的文章。Coursera是由斯坦福計(jì)算機(jī)學(xué)家達(dá)夫妮·科勒(Daphne Koller)和吳恩達(dá)(Andrew Ng)共同創(chuàng)建的。兩周之前，我返回帕洛阿爾托去再次拜訪這些網(wǎng)站。當(dāng)我去年5月造訪該網(wǎng)站時(shí)，約有30萬(wàn)人正在攻讀由斯坦福大學(xué)的教授和其他幾個(gè)高等學(xué) 府開設(shè)的38門課程。今天，這個(gè)網(wǎng)站擁有240萬(wàn)學(xué)生，他們?cè)趯W(xué)習(xí)包括八所國(guó)際性大學(xué)在內(nèi)的33所大學(xué)開辦的214門課程，

Anant Agarwal, the former director of M.I.T.’s artificial intelligence lab, is now president of edX, a nonprofit MOOC that M.I.T. and Harvard are jointly building. Agarwal told me that since May, some 155,000 students from around the world have taken edX’s first course: an M.I.T. intro class on circuits. “That is greater than the total number of M.I.T. alumni in its 150-year history,” he said.

阿南特·阿加瓦爾(Anant Agarwal)曾任麻省理工學(xué)院人工智能實(shí)驗(yàn)室主任，他現(xiàn)在是麻省理工學(xué)院和哈佛大學(xué)(Harvard)聯(lián)手打造的非營(yíng)利MOOC項(xiàng)目——edX的總 裁。阿加瓦爾對(duì)我說(shuō)，自去年5月以來(lái)，全球已有15.5萬(wàn)名學(xué)生參加了edX的第一門課程：由麻省理工學(xué)院開設(shè)的電路學(xué)初級(jí)課程。他說(shuō)，“參加這門課的學(xué) 生人數(shù)比麻省理工學(xué)院150年歷史中所有校友的人數(shù)還要高。”

Yes, only a small percentage complete all the work, and even they still tend to be from the middle and upper classes of their societies, but I am convinced that within five years these platforms will reach a much broader demographic. Imagine how this might change U.S. foreign aid. For relatively little money, the U.S. could rent space in an Egyptian village, install two dozen computers and high-speed satellite Internet access, hire a local teacher as a facilitator, and invite in any Egyptian who wanted to take online courses with the best professors in the world, subtitled in Arabic.

的確，只有一小部分的學(xué)生完成了所有的功課，即便是他們，往往也來(lái)自其所在社會(huì)的中上層階級(jí)，不過(guò)我確信，在五年之內(nèi)，這些平臺(tái)將能觸及更廣大范圍 內(nèi)的民眾。想象一下它可能如何改變美國(guó)的對(duì)外援助。美國(guó)可以用相對(duì)微不足道的資金，在埃及的村子里租賃個(gè)空間，安裝20幾臺(tái)電腦和高速衛(wèi)星上網(wǎng)設(shè)施，雇傭 一名當(dāng)?shù)氐睦蠋焷?lái)進(jìn)行服務(wù)，再邀請(qǐng)任何想要學(xué)習(xí)在線課程的埃及人聆聽全球最棒的教授們的課程，這些課程還可提供阿拉伯文字幕。

YOU just have to hear the stories told by the pioneers in this industry to appreciate its revolutionary potential. One of Koller’s favorites is about “Daniel,” a 17-year-old with autism who communicates mainly by computer. He took an online modern poetry class from Penn. He and his parents wrote that the combination of rigorous academic curriculum, which requires Daniel to stay on task, and the online learning system that does not strain his social skills, attention deficits or force him to look anyone in the eye, enable him to better manage his autism. Koller shared a letter from Daniel, in which he wrote: “Please tell Coursera and Penn my story. I am a 17-year-old boy emerging from autism. I can’t yet sit still in a classroom so [your course] was my first real course ever. During the course, I had to keep pace with the class, which is unheard-of in special ed. Now I know I can benefit from having to work hard and enjoy being in sync with the world.”

你一定要聽聽這個(gè)行業(yè)的先行者們所說(shuō)的故事，才能真正理解MOOC的那種革命性潛能?？评兆钕矚g的一個(gè)故事是關(guān)于“丹尼爾”(Daniel)的。丹 尼爾是一名17歲的自閉癥患者，他主要依靠計(jì)算機(jī)和別人交流。他參加了賓夕法尼亞大學(xué)(University of Pennsylvania)開辦的一門網(wǎng)絡(luò)現(xiàn)代詩(shī)課程。他和父母寫道，嚴(yán)格的學(xué)術(shù)課程迫使丹尼爾專注于手里的任務(wù)，而在線學(xué)習(xí)系統(tǒng)不會(huì)受限于他在社交能力 方面的不足和他的注意力缺失癥，或逼迫他與人對(duì)視，這些因素組合在一起，讓他能夠更好地控制自己的自閉癥。科勒分享了來(lái)自丹尼爾的一封信，后者在信中寫 道：“請(qǐng)把我的故事告訴Coursera和賓夕法尼亞大學(xué)。我是一名正在走出自閉癥的17歲男孩。目前我還無(wú)法坐在一間教室里，所以(你們的課)是我所上 過(guò)的第一個(gè)真正的課程。上課過(guò)程中，我必須要跟上班里的進(jìn)度，這在特殊教育當(dāng)中前所未聞。現(xiàn)在，我知道自己必須努力學(xué)習(xí)，之后我就能從中獲益，我喜歡這種 與世界同步的感覺(jué)。”

One member of the Coursera team who recently took a Coursera course on sustainability told me that it was so much more interesting than a similar course he had taken as an undergrad. The online course included students from all over the world, from different climates, incomes levels and geographies, and, as a result, “the discussions that happened in that course were so much more valuable and interesting than with people of similar geography and income level” in a typical American college.

Coursera團(tuán)隊(duì)的一名成員最近參加了一門可持續(xù)發(fā)展課程，他對(duì)我說(shuō)，這門課程比他上大學(xué)時(shí)所學(xué)的類似課程有趣很多。這門網(wǎng)絡(luò)課程包括來(lái)自世界 各地的學(xué)生，他們來(lái)自氣候不同的地域、收入水平和所在地的地理情況也不同，結(jié)果就是，與在美國(guó)一所典型大學(xué)里“和來(lái)自類似地理環(huán)境及收入水平的群體進(jìn)行的 討論相比，這門課程里的討論更有價(jià)值、也有趣得多。”

Mitch Duneier, a Princeton sociology professor, wrote an essay in The Chronicle of Higher Education in the fall about his experience teaching a class through Coursera: “A few months ago, just as the campus of Princeton University had grown nearly silent after commencement, 40,000 students from 113 countries arrived here via the Internet to take a free course in introductory sociology. ... My opening discussion of C. Wright Mills’s classic 1959 book, ‘The Sociological Imagination,’ was a close reading of the text, in which I reviewed a key chapter line by line. I asked students to follow along in their own copies, as I do in the lecture hall. When I give this lecture on the Princeton campus, I usually receive a few penetrating questions. In this case, however, within a few hours of posting the online version, the course forums came alive with hundreds of comments and questions. Several days later there were thousands. ... Within three weeks I had received more feedback on my sociological ideas than I had in a career of teaching, which significantly influenced each of my subsequent lectures and seminars.”

去年秋天，普林斯頓大學(xué)(Princeton University)社會(huì)學(xué)教授米切爾·鄧奈爾(Mitch Duneier)為《高等教育紀(jì)事報(bào)》(Chronicle of Higher Education)撰寫了一篇文章，文中講述了他通過(guò)Coursera平臺(tái)教授一門課的經(jīng)歷：“幾個(gè)月前，就在畢業(yè)典禮之后，普林斯頓大學(xué)校園變得幾乎 沉寂的時(shí)候，來(lái)自全球113個(gè)國(guó)家的4萬(wàn)名學(xué)生通過(guò)互聯(lián)網(wǎng)來(lái)到這里，參加了一門免費(fèi)的社會(huì)學(xué)初級(jí)課程......作為開課后的首次公開討論的一部分，我對(duì) C·懷特·米爾斯(C. Wright Mills)1959年的經(jīng)典之作《社會(huì)學(xué)的想象》(The Sociological Imagination)進(jìn)行了一次精讀，對(duì)其中的一篇核心章節(jié)進(jìn)行了逐字逐句的研讀。我讓學(xué)生們對(duì)照自己手中的書，跟著我閱讀，就像我在校園課堂上所做 的那樣。當(dāng)我在普林斯頓大學(xué)校園做講座時(shí)，我通常只能收到幾條鞭辟入里的問(wèn)題。然而這一次，類似的討論被貼上線才幾個(gè)小時(shí)，在線課堂論壇就涌現(xiàn)了數(shù)百條評(píng) 論和問(wèn)題。數(shù)日之后，評(píng)論和問(wèn)題的數(shù)量達(dá)到了數(shù)千條......三周之內(nèi)，我收到的與自己的社會(huì)學(xué)見解有關(guān)的反饋比我整個(gè)教學(xué)生涯中收到的還要多，它們極 大地影響了我之后的每次大課和討論課。

Agarwal of edX tells of a student in Cairo who was taking the circuits course and was having difficulty. In the class’s online forum, where students help each other with homework, he posted that he was dropping out. In response, other students in Cairo in the same class invited him to meet at a teahouse, where they offered to help him stay in the course. A 15-year-old student in Mongolia, who took the same class as part of a blended course and received a perfect score on the final exam, added Agarwal, is now applying to M.I.T. and the University of California, Berkeley.

edX的阿加瓦爾講述了一名開羅學(xué)生的故事，他參加了電路學(xué)課程的學(xué)習(xí)，并遇到了困難。在該課程的在線論壇里，學(xué)生們彼此互助，來(lái)完成作業(yè)。他在論 壇里發(fā)帖說(shuō)，他正準(zhǔn)備退課。其他參加了同一項(xiàng)課程的開羅學(xué)生做出回應(yīng)，邀請(qǐng)他在一家茶館見面。他們?cè)谀抢锾岢鰩退险n程進(jìn)度。阿加瓦爾補(bǔ)充道，作為所修 的混合式課程的一部分，一名15歲的蒙古學(xué)生也參加了這個(gè)課程，他在期末考試時(shí)獲得了優(yōu)異的成績(jī)，現(xiàn)在正在申請(qǐng)到麻省理工學(xué)院和加州大學(xué)伯克利分校 (University of California, Berkeley)就學(xué)。

As we look to the future of higher education, said the M.I.T. president, L. Rafael Reif, something that we now call a “degree” will be a concept “connected with bricks and mortar” — and traditional on-campus experiences that will increasingly leverage technology and the Internet to enhance classroom and laboratory work. Alongside that, though, said Reif, many universities will offer online courses to students anywhere in the world, in which they will earn “credentials” — certificates that testify that they have done the work and passed all the exams. The process of developing credible credentials that verify that the student has adequately mastered the subject — and did not cheat — and can be counted on by employers is still being perfected by all the MOOCs. But once it is, this phenomenon will really scale.

麻省理工學(xué)院校長(zhǎng)L·拉斐爾·賴夫(L. Rafael Reif)說(shuō)，當(dāng)我們把目光投向高等教育的未來(lái)時(shí)，現(xiàn)在被我們稱作“學(xué)位”的東西將成為一個(gè)與傳統(tǒng)的校內(nèi)學(xué)習(xí)經(jīng)歷相關(guān)聯(lián)的概念，而這種學(xué)習(xí)經(jīng)歷也將越來(lái)越 多地利用科技和網(wǎng)絡(luò)，來(lái)強(qiáng)化在教室和實(shí)驗(yàn)室進(jìn)行的教學(xué)活動(dòng)。與此同時(shí)，許多大學(xué)會(huì)給世界各地的學(xué)生提供在線課程，他們可以通過(guò)這些課程獲得“資格證書”， 這些證書可以證明他們已經(jīng)完成了學(xué)業(yè)、通過(guò)了所有考試，賴夫表示。所有MOOC項(xiàng)目依然在完善一套流程，即開發(fā)可靠的資格證書評(píng)審系統(tǒng)，以確認(rèn)一名學(xué)生已 經(jīng)充分地掌握了課程內(nèi)容、沒(méi)有作弊、而且能夠達(dá)到雇主的要求。一旦成功，MOOC將出現(xiàn)巨大增長(zhǎng)。
