-
ANANT AGARWAL: I'd like to reimagine education.
-
The last year has seen the invention of a new four letter word.
-
It starts with an "M."
-
MOOC.
-
Massive Open Online Courses.
-
Many organizations are offering these online courses to students
-
all over the world in the millions for free.
-
Anybody who has an internet connection and the will to learn
-
can access these great courses from excellent universities
-
and get a credential at the end of it.
-
Now, in this discussion today, I want to focus on a different aspect of MOOCs.
-
We are taking what we're learning and the technologies
-
we are developing in the large and applying them in the small
-
to create a blended model of education, to really reinvent and reimagine
-
what we do in the classroom.
-
Now, our classrooms could use change.
-
So here's a classroom at this little three letter
-
institute in the Northeast of America, MIT.
-
And this was a classroom 50, 60 years ago, and this is the classroom today.
-
What's changed?
-
The seats are in color.
-
Whoop dee do.
-
Education really hasn't changed in the past 500 years.
-
So the last big innovation in education was
-
the printing press and the textbooks.
-
Everything else has changed around us.
-
From health care to transportation, everything is different.
-
But education hasn't changed.
-
It's also been a real issue in terms of access.
-
So what you see here is not a rock concert.
-
And the person you see at the end of the stage is not Madonna.
-
This is a classroom at the Obafemi Awolowo University in Nigeria.
-
Now, we have all heard of distance education,
-
but the students way in the back, 200 feet away from the instructor,
-
I think they are undergoing long distance education.
-
Now, I really believe that we can transform education
-
both in quality and scale and access through technology.
-
For example, at edX, we're trying to transform education
-
through online technologies.
-
Given education has been calcified for 500 years,
-
we really cannot think about re-engineering it.
-
Micromanaging it.
-
We really have to completely reimagine it.
-
It's like going from ox carts to the airplane.
-
Even the infrastructure has to change.
-
Everything has to change.
-
We need to go from lectures on the blackboard
-
to online exercises, online videos.
-
We have to go to interactive virtual laboratories and gamification.
-
We have to go to completely online grading
-
and peer interaction and discussion boards.
-
Everything really has to change.
-
So at edX and a number of other organizations,
-
we are applying these technologies to education
-
through MOOCs to really increase access to education.
-
And you have heard of this example where,
-
when we launched our very first course-- and this
-
was an MIT-hard circuits and electronics course about a year and a half ago--
-
155,000 students from 162 countries enrolled in this course.
-
And we had no marketing budget.
-
Now, 155,000 is a big number.
-
This number is bigger than the total number
-
of alumni of MIT in it's 150 year history.
-
7,200 students passed the course, and this was a hard course.
-
7,200 is also a big number.
-
If I were to teach at MIT two semesters every year,
-
I would have to teach for 40 years before I
-
could teach this many students.
-
Now, these large numbers are just one part of the story.
-
So, today, I want to discuss a different aspect, the other side of MOOCs,
-
take a different perspective.
-
We are taking what we develop and learn in the large and apply in the small
-
to the classroom to create a blended model of learning.
-
But before I go into that, let me tell you a story.
-
When my daughter turned 13, became a teenager, she stopped speaking English.
-
She began speaking this new language.
-
I call it Teenglish it's a digital language.
-
It's got two sounds, a grunt and a silence.
-
Honey, come over for dinner?
-
Hmm.
-
Did you hear me?
-
Silence.
-
Can you listen to me?
-
Hmm.
-
So we had a real issue with communicating,
-
and we were just not communicating until one day I had this epiphany.
-
I texted her, I got an instant response.
-
I said, no, that must have been by accident.
-
She must have thought some friend of hers calling her.
-
So I texted her again.
-
Boom.
-
Another response.
-
I said, this is great.
-
And since then, my life has changed.
-
I text her.
-
She responds.
-
It's just been absolutely great.
-
[APPLAUSE]
-
So our millennial generation is built differently.
-
Now, I'm older.
-
I mean, my youthful looks might belie that,
-
but I'm not in the millennial generation.
-
But our kids are really different.
-
The millennial generation is completely comfortable with online technology.
-
So why are we fighting it in the classroom?
-
Let's not fight it.
-
Let's embrace it.
-
In fact, I believe-- and I have two fat thumbs.
-
I can't text very well.
-
But I'm willing to bet that, with evolution,
-
our kids and then the grandchildren will develop really,
-
really little, itty bitty thumbs to text much better.
-
Evolution will fix all of that stuff.
-
But so why don't we embrace technology?
-
Embrace the millennial generation's natural predilections
-
and really think about creating these online technologies,
-
blend them into their lives?
-
So here's what we can do.
-
So rather than drive our kids into a classroom,
-
herding them out there at 8 o'clock in the morning.
-
I hated going to class at 8 o'clock in the morning.
-
So why are we forcing our kids to do that?
-
So instead what you do is you have them watch videos
-
and do interactive exercises in the comfort of their dorm rooms,
-
in their bedroom, in the dining room, in the bathroom,
-
wherever they're most creative.
-
Then they come into the classroom for some in person interaction.
-
They can have discussions among themselves.
-
They can solve problems together.
-
They can work with the professor and have
-
the professor answer their questions.
-
In fact, with edX, when we were teaching our first course
-
on circuits and electronics around the world,
-
this was happening unbeknownst to us.
-
Two high school teachers at the Sant High School,
-
in Mongolia, had flipped the classroom, and they were using our video lectures
-
and interactive exercises, where the learners in the high school--
-
15-year-olds, mind you-- would go and do these things in their own homes
-
and they would come into class and, as you see from this image here,
-
they would interact with each other and do some physical laboratory work.
-
And the only way we discovered this was they wrote a blog
-
and we happened to stumble upon that blog.
-
We are also doing other pilots.
-
So we did a pilot, experimental blended course
-
working with San Jose State University in California.
-
Again, with the circuit and electronics course, you'll hear that a lot.
-
That course has become sort of like our Petri dish of learning.
-
So there the students would-- again, the instructors
-
flipped the classroom, blended online and in person,
-
and the results were staggering.
-
Now, don't take these results to the bank just yet.
-
Just wait a little bit longer as we experiment with this some more,
-
but the early results are incredible.
-
So, traditionally, semester upon semester for the past several years,
-
this course, again, a hard course, had a failure rate of about 40% to 41%
-
every semester.
-
With this blended class late last year, the failure rate fell to 9%.
-
So the results can be extremely, extremely good.
-
Now, before we go up too far into this, I'd
-
like to spend some time discussing some key ideas.
-
Some key ideas that make all of this work?
-
One idea is active learning.
-
The idea here is, rather than have students
-
walk into class and watch lectures, replace this with what we call lessons.
-
Lessons are interleaved sequences of videos and interactive exercises.
-
So students might watch a five, seven minute video,
-
and follow that with an interactive exercise.
-
Think of this as the ultimate Socratization of education.
-
You teach by asking questions.
-
And this a form of learning called active learning.
-
And really promoted by a very early paper in 1972 by Craik and Lockhart,
-
where they said and discovered that learning
-
and retention really relate strongly to the depth of mental processing.
-
Students learn much better when they are interacting with the material.
-
The second idea is self pacing.
-
Now when I went to a lecture hall and if you were like me, by the fifth minute,
-
I would lose the professor.
-
I wasn't all that smart.
-
And I would be scrambling taking notes.
-
And then I would lose the lecture for the rest of the hour.
-
Instead, wouldn't it be nice with online technologies,
-
we offer videos and interactive engagements
-
with students-- they can hit the pause button.
-
They can rewind the professor.
-
Heck, they can even mute the professor.
-
So this form of self pacing can be very helpful to learning.
-
The third idea that we have is instant feedback.
-
With instant feedback, the computer grades exercises.
-
How else do you teach 150,000 students?
-
Your computer is reading all the exercises.
-
And people all submitted homeworks, and your grades come back two weeks later,
-
you've forgotten all about it.
-
I don't think I've still received some of my homeworks
-
from my undergraduate days.
-
Someone never graded them.
-
So with instant feedback, students can try to apply answers.
-
If they get it wrong, they can get instant feedback.
-
They can try it again and try it again.
-
And this really becomes much more engaging
-
when they get the instant feedback.
-
And this little green check mark that you see here
-
is becoming somewhat of a cult symbol at edX.
-
Learners are telling us that they go to bed
-
at night dreaming of the green check mark.
-
In fact, one of our learners who took the circuits course early last year,
-
he then went on to take a software course from Berkeley
-
at the end of the year.
-
And this is what the learner had to say on our discussion board
-
when he just started that course about the green check mark.
-
Oh god; have I missing you.
-
When's the last time you have seen students
-
posting comments like this about homework?
-
My colleague Ed Bertschinger, who heads up the physics department at MIT,
-
has this to say about instant feedback.
-
And he indicated that instant feedback turns teaching moments
-
into learning outcomes.
-
The next big idea is gamification.
-
All learners engage really well with interactive videos and so on.
-
They would sit down and shoot alien spaceships all day
-
long until they get it.
-
So we applied these gamification techniques to learning.
-
And we can build these online laboratories.
-
How do you teach creativity?
-
How do you teach design?
-
We can do this through online labs and use computing power
-
to build these online labs.
-
So as this little video shows here, you can engage students much like they
-
designed with LEGOs.
-
So here, the learners are building a circuit with LEGO-like ease.
-
And this can also be graded by the computer.
-
Fifth is peer learning.
-
So here we use discussion forums and discussions and Facebook
-
like interaction not as a distraction but to really help students learn.
-
Let me tell you a story.
-
When we did the circuits course with the 155,000 students,
-
I didn't sleep for three nights leading up to the launch of the course.
-
In fact, one of my TAs, OK.
-
7 by 24.
-
We're going to be up monitoring the forum answering questions.
-
Now, I had answered questions for 100 students.
-
How do you do that for 150,000?
-
So one night, I'm sitting up there 2:00 AM at night.
-
And I think there was this question from a student from Pakistan.
-
And he asked a question.
-
And I said, OK, let me go up type up an answer.
-
I don't type all that fast.
