Why massive open online courses (still) matter

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