Why massive open online courses (still) matter
-
0:00 - 0:04I'd like to reimagine education.
-
0:04 - 0:05The last year
-
0:05 - 0:08has seen the invention of a new four-letter word.
-
0:08 - 0:10It starts with an M.
-
0:10 - 0:14MOOC: massive open online courses.
-
0:14 - 0:16Many organizations
-
0:16 - 0:19are offering these online courses
-
0:19 - 0:23to students all over the world, in the millions, for free.
-
0:23 - 0:24Anybody who has an Internet connection
-
0:24 - 0:27and the will to learn can access these great courses
-
0:27 - 0:29from excellent universities
-
0:29 - 0:32and get a credential at the end of it.
-
0:32 - 0:35Now, in this discussion today,
-
0:35 - 0:36I'm going to focus
-
0:36 - 0:39on a different aspect of MOOCs.
-
0:39 - 0:42We are taking what we are learning
-
0:42 - 0:44and the technologies we are developing in the large
-
0:44 - 0:46and applying them in the small
-
0:46 - 0:49to create a blended model of education
-
0:49 - 0:51to really reinvent and reimagine
-
0:51 - 0:53what we do in the classroom.
-
0:53 - 0:56Now, our classrooms could use change.
-
0:56 - 0:58So, here's a classroom
-
0:58 - 1:00at this little three-letter institute
-
1:00 - 1:03in the Northeast of America, MIT.
-
1:03 - 1:06And this was a classroom about 50 or 60 years ago,
-
1:06 - 1:09and this is a classroom today.
-
1:09 - 1:12What's changed?
-
1:12 - 1:15The seats are in color.
-
1:15 - 1:18Whoop-de-do.
-
1:18 - 1:21Education really hasn't changed
-
1:21 - 1:22in the past 500 years.
-
1:22 - 1:25The last big innovation in education
-
1:25 - 1:28was the printing press and the textbooks.
-
1:28 - 1:29Everything else has changed around us.
-
1:29 - 1:31You know, from healthcare to transportation,
-
1:31 - 1:36everything is different,
but education hasn't changed. -
1:36 - 1:38It's also been a real issue in terms of access.
-
1:38 - 1:40So what you see here
-
1:40 - 1:43is not a rock concert.
-
1:43 - 1:45And the person you see at the end of the stage
-
1:45 - 1:47is not Madonna.
-
1:47 - 1:49This is a classroom
-
1:49 - 1:53at the Obafemi Awolowo University in Nigeria.
-
1:53 - 1:57Now, we've all heard of distance education,
-
1:57 - 1:58but the students way in the back,
-
1:58 - 2:01200 feet away from the instructor,
-
2:01 - 2:06I think they are undergoing long-distance education.
-
2:06 - 2:07Now, I really believe
-
2:07 - 2:09that we can transform education,
-
2:09 - 2:12both in quality and scale and access,
-
2:12 - 2:15through technology.
-
2:15 - 2:18For example, at edX,
-
2:18 - 2:20we are trying to transform education
-
2:20 - 2:24through online technologies.
-
2:24 - 2:27Given education has been calcified for 500 years,
-
2:27 - 2:29we really cannot think about reengineering it,
-
2:29 - 2:30micromanaging it.
-
2:30 - 2:33We really have to completely reimagine it.
-
2:33 - 2:37It's like going from ox carts to the airplane.
-
2:37 - 2:38Even the infrastructure has to change.
-
2:38 - 2:40Everything has to change.
-
2:40 - 2:43We need to go from lectures on the blackboard
-
2:43 - 2:46to online exercises, online videos.
-
2:46 - 2:48We have to go to interactive virtual laboratories
-
2:48 - 2:50and gamification.
-
2:50 - 2:52We have to go to completely online grading
-
2:52 - 2:55and peer interaction and discussion boards.
-
2:55 - 2:57Everything really has to change.
-
2:57 - 2:59So at edX and a number of other organizations,
-
2:59 - 3:01we are applying these technologies to education
-
3:01 - 3:05through MOOCs to really
increase access to education. -
3:05 - 3:06And you heard of this example,
-
3:06 - 3:09where, when we launched our very first course --
-
3:09 - 3:11and this was an MIT-hard
-
3:11 - 3:12circuits and electronics course --
-
3:12 - 3:15about a year and a half ago,
-
3:15 - 3:20155,000 students from 162 countries
-
3:20 - 3:22enrolled in this course.
-
3:22 - 3:25And we had no marketing budget.
-
3:25 - 3:28Now, 155,000 is a big number.
-
3:28 - 3:30This number is bigger
-
3:30 - 3:33than the total number of alumni of MIT
-
3:33 - 3:36in its 150-year history.
-
3:36 - 3:397,200 students passed the course,
-
3:39 - 3:41and this was a hard course.
-
3:41 - 3:447,200 is also a big number.
-
3:44 - 3:48If I were to teach at MIT two semesters every year,
-
3:48 - 3:51I would have to teach for 40 years
-
3:51 - 3:53before I could teach this many students.
-
3:53 - 3:55Now these large numbers
-
3:55 - 3:57are just one part of the story.
-
3:57 - 4:00So today, I want to discuss a different aspect,
-
4:00 - 4:01the other side of MOOCs,
-
4:01 - 4:03take a different perspective.
-
4:03 - 4:06We are taking what we develop
and learn in the large -
4:06 - 4:08and applying it in the small
-
4:08 - 4:12to the classroom, to create
a blended model of learning. -
4:12 - 4:16But before I go into that, let me tell you a story.
-
4:16 - 4:20When my daughter turned 13, became a teenager,
-
4:20 - 4:24she stopped speaking English,
-
4:24 - 4:27and she began speaking this new language.
-
4:27 - 4:30I call it teen-lish.
-
4:30 - 4:32It's a digital language.
-
4:32 - 4:39It's got two sounds: a grunt and a silence.
-
4:39 - 4:42"Honey, come over for dinner."
-
4:42 - 4:43"Hmm."
-
4:43 - 4:46"Did you hear me?"
-
4:46 - 4:48Silence. (Laughter)
-
4:48 - 4:49"Can you listen to me?"
-
4:49 - 4:51"Hmm."
-
4:51 - 4:53So we had a real issue with communicating,
-
4:53 - 4:55and we were just not communicating,
-
4:55 - 4:58until one day I had this epiphany.
-
4:58 - 5:01I texted her. (Laughter)
-
5:01 - 5:03I got an instant response.
-
5:03 - 5:05I said, no, that must have been by accident.
-
5:05 - 5:06She must have thought, you know,
-
5:06 - 5:08some friend of hers was calling her.
-
5:08 - 5:11So I texted her again. Boom, another response.
-
5:11 - 5:13I said, this is great.
-
5:13 - 5:15And so since then, our life has changed.
-
5:15 - 5:16I text her, she responds.
-
5:16 - 5:19It's just been absolutely great.
-
5:19 - 5:25(Applause)
-
5:25 - 5:27So our millennial generation
-
5:27 - 5:28is built differently.
-
5:28 - 5:31Now, I'm older, and my
youthful looks might belie that, -
5:31 - 5:35but I'm not in the millennial generation.
-
5:35 - 5:36But our kids are really different.
-
5:36 - 5:38The millennial generation is completely comfortable
-
5:38 - 5:39with online technology.
-
5:39 - 5:41So why are we fighting it in the classroom?
-
5:41 - 5:43Let's not fight it. Let's embrace it.
-
5:43 - 5:45In fact, I believe -- and I have two fat thumbs,
-
5:45 - 5:46I can't text very well --
-
5:46 - 5:49but I'm willing to bet that with evolution,
-
5:49 - 5:51our kids and their grandchildren
-
5:51 - 5:53will develop really, really little, itty-bitty thumbs
-
5:53 - 5:54to text much better,
-
5:54 - 5:57that evolution will fix all of that stuff.
-
5:57 - 5:59But what if we embraced technology,
-
5:59 - 6:01embraced the millennial generation's
-
6:01 - 6:03natural predilections,
-
6:03 - 6:06and really think about creating
these online technologies, -
6:06 - 6:07blend them into their lives.
-
6:07 - 6:09So here's what we can do.
-
6:09 - 6:11So rather than driving our kids into a classroom,
-
6:11 - 6:14herding them out there at 8 o'clock in the morning --
-
6:14 - 6:17I hated going to class at 8 o'clock in the morning,
-
6:17 - 6:19so why are we forcing our kids to do that?
-
6:19 - 6:20So instead what you do
-
6:20 - 6:22is you have them watch videos
-
6:22 - 6:24and do interactive exercises
-
6:24 - 6:26in the comfort of their dorm rooms, in their bedroom,
-
6:26 - 6:28in the dining room, in the bathroom,
-
6:28 - 6:31wherever they're most creative.
-
6:31 - 6:33Then they come into the classroom
-
6:33 - 6:36for some in-person interaction.
-
6:36 - 6:38They can have discussions amongst themselves.
-
6:38 - 6:40They can solve problems together.
-
6:40 - 6:41They can work with the professor
-
6:41 - 6:44and have the professor answer their questions.
-
6:44 - 6:48In fact, with edX, when we
were teaching our first course -
6:48 - 6:50on circuits and electronics around the world,
-
6:50 - 6:53this was happening unbeknownst to us.
-
6:53 - 6:54Two high school teachers
-
6:54 - 6:58at the Sant High School in Mongolia
-
6:58 - 7:00had flipped their classroom,
-
7:00 - 7:02and they were using our video lectures
-
7:02 - 7:04and interactive exercises,
-
7:04 - 7:06where the learners in the high school,
-
7:06 - 7:0715-year-olds, mind you,
-
7:07 - 7:09would go and do these things in their own homes
-
7:09 - 7:10and they would come into class,
-
7:10 - 7:12and as you see from this image here,
-
7:12 - 7:13they would interact with each other
-
7:13 - 7:16and do some physical laboratory work.
-
7:16 - 7:17And the only way we discovered this
-
7:17 - 7:19was they wrote a blog
-
7:19 - 7:23and we happened to stumble upon that blog.
-
7:23 - 7:25We were also doing other pilots.
-
7:25 - 7:27So we did a pilot experimental blended courses,
-
7:27 - 7:30working with San Jose State University in California,
-
7:30 - 7:32again, with the circuits and electronics course.
-
7:32 - 7:34You'll hear that a lot. That course has become
-
7:34 - 7:38sort of like our petri dish of learning.
-
7:38 - 7:40So there, the students would, again,
-
7:40 - 7:43the instructors flipped the classroom,
-
7:43 - 7:45blended online and in person,
-
7:45 - 7:47and the results were staggering.
-
7:47 - 7:50Now don't take these results to the bank just yet.
-
7:50 - 7:52Just wait a little bit longer as we
experiment with this some more, -
7:52 - 7:54but the early results are incredible.
-
7:54 - 7:57So traditionally, semester upon semester,
-
7:57 - 7:59for the past several years, this course,
-
7:59 - 8:01again, a hard course,
-
8:01 - 8:04had a failure rate of about 40 to 41 percent
-
8:04 - 8:05every semester.
-
8:05 - 8:08With this blended class late last year,
-
8:08 - 8:12the failure rate fell to nine percent.
-
8:12 - 8:16So the results can be extremely, extremely good.
-
8:16 - 8:19Now before we go too far into this,
-
8:19 - 8:22I'd like to spend some time discussing
-
8:22 - 8:23some key ideas.
-
8:23 - 8:24What are some key ideas
-
8:24 - 8:27that makes all of this work?
-
8:27 - 8:29One idea is active learning.
-
8:29 - 8:32The idea here is, rather than have students
-
8:32 - 8:34walk into class and watch lectures,
-
8:34 - 8:37we replace this with what we call lessons.
-
8:37 - 8:39Lessons are interleaved sequences
-
8:39 - 8:42of videos and interactive exercises.
-
8:42 - 8:45So a student might watch a five-, seven-minute video
-
8:45 - 8:48and follow that with an interactive exercise.
-
8:48 - 8:51Think of this as the ultimate
Socratization of education. -
8:51 - 8:53You teach by asking questions.
-
8:53 - 8:55And this is a form of learning
-
8:55 - 8:56called active learning,
-
8:56 - 8:59and really promoted by a very early paper, in 1972,
-
8:59 - 9:01by Craik and Lockhart,
-
9:01 - 9:02where they said and discovered
-
9:02 - 9:04that learning and retention really relates strongly
-
9:04 - 9:06to the depth of mental processing.
-
9:06 - 9:08Students learn much better
-
9:08 - 9:11when they are interacting with the material.
-
9:11 - 9:14The second idea is self-pacing.
-
9:14 - 9:15Now, when I went to a lecture hall,
-
9:15 - 9:17and if you were like me,
-
9:17 - 9:19by the fifth minute I would lose the professor.
-
9:19 - 9:22I wasn't all that smart, and I would
be scrambling, taking notes, -
9:22 - 9:25and then I would lose the lecture
for the rest of the hour. -
9:25 - 9:28Instead, wouldn't it be nice with online technologies,
-
9:28 - 9:32we offer videos and interactive
engagements to students? -
9:32 - 9:33They can hit the pause button.
-
9:33 - 9:36They can rewind the professor.
-
9:36 - 9:39Heck, they can even mute the professor.
-
9:39 - 9:41So this form of self-pacing
-
9:41 - 9:44can be very helpful to learning.
-
9:44 - 9:47The third idea that we have is instant feedback.
-
9:47 - 9:49With instant feedback,
-
9:49 - 9:50the computer grades exercises.
-
9:50 - 9:53I mean, how else do you teach 150,000 students?
-
9:53 - 9:55Your computer is grading all the exercises.
-
9:55 - 9:57And we've all submitted homeworks,
-
9:57 - 9:59and your grades come back two weeks later,
-
9:59 - 10:00you've forgotten all about it.
-
10:00 - 10:02I don't think I've still received
some of my homeworks -
10:02 - 10:04from my undergraduate days.
-
10:04 - 10:05Some are never graded.
-
10:05 - 10:07So with instant feedback,
-
10:07 - 10:08students can try to apply answers.
-
10:08 - 10:10If they get it wrong, they can get instant feedback.
-
10:10 - 10:12They can try it again and try it again,
-
10:12 - 10:14and this really becomes much more engaging.
-
10:14 - 10:16They get the instant feedback,
-
10:16 - 10:19and this little green check mark that you see here
-
10:19 - 10:22is becoming somewhat of a cult symbol at edX.
-
10:22 - 10:25Learners are telling us that they go to bed at night
-
10:25 - 10:28dreaming of the green check mark.
-
10:28 - 10:30In fact, one of our learners
-
10:30 - 10:33who took the circuits course early last year,
-
10:33 - 10:35he then went on to take a software course
-
10:35 - 10:37from Berkeley at the end of the year,
-
10:37 - 10:39and this is what the learner had to say
-
10:39 - 10:41on our discussion board
-
10:41 - 10:42when he just started that course
-
10:42 - 10:45about the green check mark:
-
10:45 - 10:47"Oh god; have I missed you."
-
10:47 - 10:50When's the last time you've seen students
-
10:50 - 10:54posting comments like this about homework?
-
10:54 - 10:56My colleague Ed Bertschinger,
-
10:56 - 10:59who heads up the physics department at MIT,
-
10:59 - 11:01has this to say about instant feedback:
-
11:01 - 11:04He indicated that instant feedback
-
11:04 - 11:10turns teaching moments into learning outcomes.
-
11:10 - 11:12The next big idea is gamification.
-
11:12 - 11:14You know, all learners engage really well
-
11:14 - 11:16with interactive videos and so on.
-
11:16 - 11:17You know, they would sit down and shoot
-
11:17 - 11:19alien spaceships all day long until they get it.
-
11:19 - 11:22So we applied these gamification
techniques to learning, -
11:22 - 11:24and we can build these online laboratories.
-
11:24 - 11:27How do you teach creativity?
How do you teach design? -
11:27 - 11:28We can do this through online labs
-
11:28 - 11:30and use computing power
-
11:30 - 11:31to build these online labs.
-
11:31 - 11:34So as this little video shows here,
-
11:34 - 11:35you can engage students
-
11:35 - 11:37much like they design with Legos.
-
11:37 - 11:39So here, the learners are building a circuit
-
11:39 - 11:41with Lego-like ease.
-
11:41 - 11:45And this can also be graded by the computer.
-
11:45 - 11:48Fifth is peer learning.
-
11:48 - 11:50So here, we use discussion forums and discussions
-
11:50 - 11:53and Facebook-like interaction
-
11:53 - 11:54not as a distraction,
-
11:54 - 11:57but to really help students learn.
-
11:57 - 11:59Let me tell you a story.
-
11:59 - 12:02When we did our circuits course
-
12:02 - 12:04for the 155,000 students,
-
12:04 - 12:06I didn't sleep for three nights
-
12:06 - 12:08leading up to the launch of the course.
-
12:08 - 12:10I told my TAs, okay, 24/7,
-
12:10 - 12:11we're going to be up
-
12:11 - 12:13monitoring the forum, answering questions.
-
12:13 - 12:15They had answered questions for 100 students.
-
12:15 - 12:18How do you do that for 150,000?
-
12:18 - 12:20So one night I'm sitting up there, at 2 a.m. at night,
-
12:20 - 12:22and I think there's this question
-
12:22 - 12:24from a student from Pakistan,
-
12:24 - 12:25and he asked a question, and I said,
-
12:25 - 12:26okay, let me go and type up an answer,
-
12:26 - 12:28I don't type all that fast,
-
12:28 - 12:30and I begin typing up the answer,
-
12:30 - 12:31and before I can finish,
-
12:31 - 12:34another student from Egypt
popped in with an answer, -
12:34 - 12:36not quite right, so I'm fixing the answer,
-
12:36 - 12:38and before I can finish, a student from the U.S.
-
12:38 - 12:39had popped in with a different answer.
-
12:39 - 12:42And then I sat back, fascinated.
-
12:42 - 12:44Boom, boom, boom, boom, the students were
-
12:44 - 12:46discussing and interacting with each other,
-
12:46 - 12:49and by 4 a.m. that night, I'm totally fascinated,
-
12:49 - 12:50having this epiphany,
-
12:50 - 12:51and by 4 a.m. in the morning,
-
12:51 - 12:53they had discovered the right answer.
-
12:53 - 12:55And all I had to do was go and bless it,
-
12:55 - 12:57"Good answer."
-
12:57 - 12:59So this is absolutely amazing,
-
12:59 - 13:01where students are learning from each other,
-
13:01 - 13:04and they're telling us that they are learning
-
13:04 - 13:06by teaching.
-
13:06 - 13:08Now this is all not just in the future.
-
13:08 - 13:10This is happening today.
-
13:10 - 13:12So we are applying these blended learning pilots
-
13:12 - 13:15in a number of universities and
high schools around the world, -
13:15 - 13:17from Tsinghua in China
-
13:17 - 13:19to the National University of Mongolia in Mongolia
-
13:19 - 13:21to Berkeley in California --
-
13:21 - 13:22all over the world.
-
13:22 - 13:24And these kinds of technologies really help,
-
13:24 - 13:26the blended model can really help
-
13:26 - 13:28revolutionize education.
-
13:28 - 13:31It can also solve a practical problem of MOOCs,
-
13:31 - 13:33the business aspect.
-
13:33 - 13:35We can also license these MOOC courses
-
13:35 - 13:37to other universities,
-
13:37 - 13:39and therein lies a revenue model for MOOCs,
-
13:39 - 13:42where the university that
licenses it with the professor -
13:42 - 13:44can use these online courses
-
13:44 - 13:46like the next-generation textbook.
-
13:46 - 13:48They can use as much or as little as they like,
-
13:48 - 13:54and it becomes a tool in the teacher's arsenal.
-
13:54 - 13:56Finally, I would like to have you
-
13:56 - 13:59dream with me for a little bit.
-
13:59 - 14:03I would like us to really reimagine education.
-
14:03 - 14:07We will have to move from lecture halls to e-spaces.
-
14:07 - 14:10We have to move from books to tablets
-
14:10 - 14:12like the Aakash in India
-
14:12 - 14:14or the Raspberry Pi, 20 dollars.
-
14:14 - 14:16The Aakash is 40 dollars.
-
14:16 - 14:19We have to move from
bricks-and-mortar school buildings -
14:19 - 14:21to digital dormitories.
-
14:21 - 14:23But I think at the end of the day,
-
14:23 - 14:25I think we will still need one lecture hall
-
14:25 - 14:28in our universities.
-
14:28 - 14:31Otherwise, how else do we tell our grandchildren
-
14:31 - 14:34that your grandparents sat in that room
-
14:34 - 14:37in neat little rows like cornstalks
-
14:37 - 14:40and watched this professor at the end
-
14:40 - 14:42talk about content and, you know,
-
14:42 - 14:45you didn't even have a rewind button?
-
14:45 - 14:47Thank you.
-
14:47 - 14:49(Applause)
-
14:49 - 14:56Thank you. Thank you. (Applause)
- Title:
- Why massive open online courses (still) matter
- Speaker:
- Anant Agarwal
- Description:
-
2013 was a year of hype for MOOCs (massive open online courses). Great big numbers and great big hopes were followed by some disappointing first results. But the head of edX, Anant Agarwal, makes the case that MOOCs still matter -- as a way to share high-level learning widely and supplement (but perhaps not replace) traditional classrooms. Agarwal shares his vision of blended learning, where teachers create the ideal learning experience for 21st century students.
