Will
Artificial Intelligence Save, Replace or even Affect Education Practices?
(a
venture capitalist’s view)
AI, a.k.a.
artificial intelligence, is a highly efficient artificial pattern recognition system (for recognizing patterns with a finite
number of variations).
HI, a.k.a. human
intelligence, is a highly efficient natural system for creating solutions to problems which have never been solved before;
the central ability of the host of HI is an ability to create a solution to a
new problem (this is
what I teach my students, no matter what specific subject I teach at the time: http://www.GoMars.xyz/vvli.html; www.GoMars.xyz/vv.htm).
In
short:
1.
Various advances in AI are becoming a common place (the latest example is AlphaGo Zero: https://www.nature.com/articles/nature24270).
2.
Professionals know that there is still a huge distance between AI and HI.
However, for general public, a competition between various versions of AI
(produced be different companies: https://www.forbes.com/sites/quora/2017/02/24/what-companies-are-winning-the-race-for-artificial-intelligence/#ffe12f0f5cd8)
is seen as a competition between different sport teams: for example,
self-driving cars = “race cars”; Chess, Go, Jeopardy winners = “sport
champions”.
3.
From the point of view of attracting public attention, i.e. marketing, the most
promising actions should be based on more and more complicated competitions between
AI and HI. Personally, I would like to see a human and an AI taking the same standard (commercially
available) IQ tests (https://www.mensa.lu/en/mensa/online-iq-test.html).
4.
Games like Chess and Go are not considered as popular as TV shows, but various
competitions, like science subject Olympiads, may resonate with general public.
That is why the next battle between AI and HI, which may attract wide attention
of general public, should happen at the next Physics Olympiad (so far,
excluding the practical/experimental part, and competing only in the
theoretical part, solving problems similar to “F=ma” test; https://www.aapt.org/physicsteam/2016/exams.cfm).
AI would be reading the same problems and solving them in real time. If AI will
win the competition, that will be a clear proof of its actual power. That
company which AI will do it first will win the marketing battle (at least for
awhile).
Currently,
no company can present AI which could solve physics problems, or math word
problems, just by reading from a textbook. This is why so far rumors about AI
replacing school teachers exaggerate the actual case.
As
an expert in HI, I know that no AI can
ever learn on its own (like AlphaGo Zero learned how to play Go) how to solve physics problems, or
math word problems randomly taken from standard textbooks.
This skill requires a high-level training which can be achieved only as the result of effective
interaction with a good teacher. That
automatically means that no AI can ever learn on its own how to be become a good
teacher (i.e. a teacher who can teach beyond memorizing and repeating
various – even very complicated – patterns (that is essentially no different
from training animals doing tricks); a teacher who can teach how to create a solution to a brand new problem:
http://teachology.xyz/general_algorithm.htm;
http://teachology.xyz/sp.htm;
http://teachology.xyz/mocc.htm;
http://teachology.xyz/la.htm).
However, I know for sure, that some of the top AI
developers disagree with the statement I just made.
Some time ago I had a meeting with
one of the high-level executives and a businessman at one of large tech
companies located in Cambridge, MA.
The
mere fact that we met was already extraordinary for me; it was the first time I
talked to such a person (BTW; I asked for a meeting three more companies, but
only one decided to take a risk).
Even
more impressive was the fact that we spent talking for more than an hour.
That
conversation helped me to take a look into a mind of a person responsible for
guiding multimillion projects.
Of
course, we talked about education.
It
did not surprise me that people like my opponent formed their view on education
via reading or watching science fiction.
In
their view, in the future a student will be interacting with AI via screens,
speech, gestures, like a student does today when interacting with a teacher.
AI
will tutor students, and will do it better than today an average teacher does.
Out
conversation has clearly shown two facts: (a) business and tech leaders have a
very overestimated view of the role AI will play in 10 to 20 years; (b)
business and tech leaders have a very trivial (if not primitive) view on
education.
Regarding
the first fact I have been writing in the past, for example: http://www.GoMars.xyz/AI.htm.
In
part, I wrote: “People working on AI believe that they can make an “artificial
brain”. This type of belief is nothing new. For thousands of years, people have
been dreaming about flying like a bird. And finally, Wright brothers invented
an airplane. At last, men can fly! Yes. But NOT like a bird! What we – humans –
created is a device which replicates one
function of a bird, i.e. flying above the ground, but to this day there is no device replicating an actual bird. The field of AI is NO
different.”
The
second fact, that business and tech leaders have a very trivial (simplistic)
view of education, is no surprise at all. They have grown up within the same
cultural framework as all regular folks have, with only one difference; since
they have achieved staggering success in life, they have even less doubts in
their abilities to make right decisions than regular folks have.
Let
us ask a question, who is smarter, Albert Einstein or Steve Jobs; Elon Musk or
Stephen Hawking? Who is smarter, the guy who was smart enough to write the
first version of what had become MS-DOS (Tim Paterson? Gary Kildall?),
or Bill Gates who was smart enough to buy it from Tim Paterson for $50,000 and
make billions of it? Is IBM’s Watson really smarter than Garry Kasparov?
Different
people may approach this question differently.
One
may say that we would need to give all those people to solve some abstract (not
based on a specific content) problems and see how would they do.
Another
approach would be saying that this question does not make any sense, because
there are multiple types of “smartness” (in the same sense Dr. Howard Gardner
talks about multiple intelligences);
i.e. there is “programming smartness”, “business smartness”, etc.
Both these approaches fit the field
of cognitive psychology.
Many people, however, do not bother
with coming up with a psychological definition of “smartness”; they just equate
“making big money” with “being smart” (folk question “if you are so smart, why ain’t you rich?” is an indication of this attitude). And
people who made big money in tech especially susceptible to this sentiment.
Self-made tech millionaires and
people who made it in the tech world from the bottom to the top believe in
paradigm: “If I made big money, that means I’m smart.”
And that might be even true.
But even the smartest person in the
world cannot know everything. When a car, or a refrigerator breaks, even the
smartest people call a professional.
“We have talked to many teachers”, I
was told during our conversation.
“How do you select who to talk to?”
“What is the chance that those
people are not as good as they present themselves?”
“How do you assess if those people
are as good as they present themselves?”
“You told me that at least two
thirds of school teachers are not good at teaching. How do you know that? How
do you know who is good and who is not? How do you know that people you talk to
are from another third?”
“What is the chance that you are so
visionary and charismatic person that when you tell people your vision they
accept it without giving to it any critical thoughts (the “Halo effect”)?”
“What is the chance that people are
much smarter and cynical than you think, and just tell you everything you like
to hear, as long as they keep getting from you free stuff (money, books,
tablets, computers, etc.)?”
“What is your personal description,
definition, of “good teaching”? How does the structure of good teaching look
for you? What is the most important result of teaching – for you – and how do
you know it was achieved?”
That type of questions I would like
to ask my conversation opponent, but I could not fit it in our hour.
If
I had more time, I also would ask the same questions about “experts” who are
usually hired to support the ideas of the influential “non-experts”. Speaking
about experts, there is one question to which I never could get a clear answer:
“How did it happen that $200,000,000
spent in Newark, NJ with the help of many experts on “improving education”,
didn’t really lead to improvement in education of Newark children?” The
fascinating story of Newark can be found in book “The Prize: Who's in Charge of
America's Schools?” by Dale Russakoff (https://www.amazon.com/The-Prize-Charge-Americas-Schools-ebook/dp/B00AXS6BIE).
A similar question I asked in my open letter to Mss. Laurene Powell Jobs, but, also, without an answer (http://www.teachology.xyz/xq.htm).
At some point in our conversation, I
was presented with a vision that in the future, when a student is struggling
with a homework, AI would recognize the struggle, and would offer a hint, like
“click on this link and watch a movie”, or something else, exactly like a human
tutor.
I mentioned that there are already
various tutoring systems on the market, and many students just hate them.
Of course, this company has
extensively studied those systems and knows how to develop AI tutor which will
be much better than the existing ones.
In case it was not very clear, the
last sentence was sarcasm.
As a person with an extensive
tutoring experience, I know that a human tutor does much more than just
offering guiding questions, or hints (http://www.GoMars.xyz/vv.htm). As an example, I used an episode
from movie “Sully”. In the episode, test pilots used a simulator to demonstrate
that the airplane did not have to land on water, that it could have been
brought back to an airport. And Capt. Chesley
"Sully" Sullenberger said to the
commission: “You do not take into account the human factor” (one of my
favorites moments in this great movie). When I was listening to my opponent, I
said exactly same words: “You do not take into account the human factor”; in
short, learning and teaching is simply much more than maintaining the flow of
information, or the sequence of physical actions – that would have been just
training (https://www.animaltrainingacademy.com/how-to-animal-training/).
I also used an example from a
science fiction story. Long time ago a red a short story about the future. At
the age of 16 all children would be assessed with the use of a “mental machine”
which would prescribe for each child his or her profession for the rest of
their life. Then each child would put a helpmeet, and a technician would charge
the machine with a tape holding all professional knowledge needed for the
child, and in a minute everyone would learn everything he or she would need to
do the work. Except some guys, who could not learn anything from the machine,
because their brain was special. Turned out those guys would be going to a
regular school to learn how to program those machines and to develop those
tapes.
The vision of education presented to
me by my opponent was of sort similar to the one described on the science
fiction story.
Instead of machines with tapes –
computers with AI.
For masses, teaching essentially
would be no different from training animals to do tricks.
I admit, that many students – those
who today do not have a good teacher – would be getting better knowledge from
AI tutor than from a human teacher.
However, parents with resources
would be lining up into elite schools where human teachers good at teaching
would be teaching their children (of course, with the help from AI).
To answering my title question, AI will affect education, and it will
affect it greatly.
Mass education will become less
dependent on the quality of teaching cadre. Knowledge and skills of an average
student will increase. Businesses will have better prepared workforce for doing
more complicated but still mostly routine work. Teachers will not disappear.
Most of them will be working in public schools using all technologies offered
by AI (in a way, this will be similar to construction workers who replaced a
simple shovel with an automatic trench digger).
The best teachers will be
concentrating in elite schools where students will learn more than just a very
specific set of skills. The will also learn how to use those skills to create
knew knowledge.
At some point in our conversation I
was told: “My child complains that it is hard to write with a pen on paper. But
using a stylus and writing on a screen is easier!”
I said: “Easier does not mean
better.”
My phrase resulted in a long pause.
For me, who has been teaching
physics and math for many years to all types of students, it was obvious that
in education “easier” does not always mean “better for students”. On the
contrary, true learning happens via overcoming obstacles and difficulties we
call “mistakes”. Another known fact is that learning how to manipulate with
fingers (including writing) helps children’s brain development.
Overcoming mistakes is the essence
of learning. Guiding through this process is coaching (training, instructing).
Teaching includes instructing but also has more (https://www.smashwords.com/books/view/665204).
But for my opponent, and many
others, “easier”, “funnier”, “down to earth” automatically means “better
teaching”.
Based on their view of education,
they only support ventures which fit their view.
I was asked “Is the project method
of teaching better than a traditional teaching?”
I said: “No”, and I was met with a
bewildered glance, and an “attack”: “But when students do projects, it is fun,
they are active”.
“OK”, I said, “I take my answer
back. I change it to – there is no evidence for either to be better”.
That is exactly the situation.
I know that many so called “project
based” approaches make it look like students learn more (students definitely look happier, though). But I also know that if the same students would be taught by a really good teacher who
would use “traditional” approach, those students would learn even more. But I
could never prove it; as well as no one can prove the opposite.
Today
there is no scientific evidence that “project based teaching” is better than
“traditional teaching”,
or the opposite (http://www.GoMars.xyz/msm.html).
First, there is no commonly accepted
definition of either type of teaching.
Second, there is no commonly
accepted measuring procedures which would allow to compare the learning
outcomes of students.
Third, there is even no commonly
accepted list of the learning outcomes expected from students at the end of a
school, or a given grade.
Today, measuring students’ learning
outcomes is like measuring temperature using different devices and scales
without any conversion factors.
The majority of the papers describe
teaching “experiments” like – paraphrasing –
1)
“We want our students to do better. For that we plan on trying this.” – if the
project mostly involves faculty or teachers who directly teach students.
or
2)
“We want our school teachers to teach better. For that we plan on trying this.”
– if the project mostly involves faculty from a school of education.
Which leads us to a simple
conclusion: nowadays, every single statement about how good or bad some form of
teaching is, represents no more than a personal opinion and can be challenged
by the opposite statement, and there is no scientific data to support either.
That
means that today there is no such thing as science of education (the scientific field does exist,
but there is no yet science).
Here we finally have come to the
goal of my visit – to discuss the state of the science of education.
Only after the meeting, reflecting
on our conversation, I realized that for more than an hour we talked about two
different things (“apples and oranges”). I was talking about science of education. My opponent was
talking about education. No wonder,
we did not understand each other (which is completely my fault – I was not
clear enough).
Before the meeting, I sent a letter,
which had this part:
“This
book (“The Structure of Scientific Revolutions” by Thomas Kuhn) is a very
famous book. First time I read it about 20 years ago. It was a Russian
translation. At the time, it was just one of many books I read on the history
and philosophy of science. But recently I decided to read it again because I
started seeing symptoms described in this book. Symptoms of a paradigm change
in a specific area; in the field of education. The crisis is not here yet, but
close, and the new paradigm has not been yet formulated, but it's in the air.
The old paradigm, which is still the current one, is very simple. It says that
learning is basically a process of imprinting the previously collected
knowledge into student’s mind, and a teacher is a person who knows what
students need and don't need to know.
There
is however a feeling that the old
paradigm might be outdated. More and more people write that students need to
learn how to think critically. However, there is no common view on what
critical thinking is, what is its structure, and more importantly how to teach
it, especially on the massive scale. Different groups offer different
approaches. And we can see the pockets
of studies which, from my point of view, will lead to a formulation of a new
paradigm. Right now we are in the transition from the old paradigm to a new
paradigm, which has not been yet presented. We are in the pre-paradigm stage”.
My intention was to attract
attention to the project which would help to advance science of education to a
true science (http://www.teachology.xyz/chs.htm).
Only after the meeting I realized
that my expectation was premature. I should have not expected from people of
such status to think about science: “Hmm, what could we do to change things in
science of education?”
I do not think this type of a
question has ever popped up in the mind of my opponent before our meeting; due to a simple reason – those people do not think about advancing science, because they do
not consider themselves scientists (http://www.GoMars.xyz/30uS.html). And also, because for many people
any kind of a search is already seen as a scientific research; which is not
actually a case.
In hindsight, I should not have been
expecting from my opponent any attention to science
of education. Unfortunately, many scientists in the field of education are not
involved into scientific projects, too. Even a top-level official at a large
research university told me once, that science of education is not possible.
Even more, there is no need for science of education at all, because education
is more like a craft; we just need more good “craftsmen”. And that was a person
who ran at some point a teacher preparation institutional entity. Finally I
understood, why my appeal to business leaders (http://www.teachology.xyz/MO.html) and my GoFundMe campaign (https://www.gofundme.com/teachology) were bound to fail.
In this paper, http://www.GoMars.xyz/nsf.html, I have shown that more than 90 %
of NSF funded projects are not scientific, but social by their nature. For
those projects, their primary goal is not producing new knowledge, but helping
teachers teach better (http://www.GoMars.xyz/3pc.htm).
Almost all “experiments” funded by
the NSF, or described in various magazines, fit the clear and universal law:
“if we take two large groups of fairly similar students, and students in the
first group will have a more extensive or
diverse learning experience (for example, more contact hours with an
instructor, or more time used for guided discussions, or more time spent on
certain exercises, or training through more and/or different exercises, etc.
than students in the second group), students from the first group, on average, will demonstrate better learning outcomes
than the students in the second group” (the 1st Law of Teachology: http://www.GoMars.xyz/6lt.html).
In teaching, this law has the same
explanatory and guiding power as the Newton’s Second Law has in physics. There
is no need for trying to prove it again and again; it should be used for
designing new teaching practices.
I have no doubts that the use of
various technologies, including AI, will lead to better education – as a human
practice.
To advance science of education someone would need to adopt a “Manhattan
Project”, or “An Apollo Program” type approach (http://www.GoMars.xyz/30uS.html).
My hope was to find a tech business
leader who would be interested in advancing science of education.
My search is still open (http://www.GoMars.xyz/YP.html).
Although, I doubt that
this particular company will invite me back again; my talking stile is too
"confrontational". However, if for some people the tone of the conversation matters
more than its substance, maybe those people should take a look in a mirror? (https://teachologyforall.blogspot.com/2017/04/polite.html).
And speaking
again about how self-made tech millionaires see education - most probably, most
of them just have not had a good teacher in their life (they may have had
friends, advisers, professional role models, but not good teachers). That is
why they do not know what a good teaching is, and how big if a difference between
a teacher and a good teacher. And when a person has not met a good teacher,
that person just cannot resonate with anything you would try to tell him or her
about good teaching. It is like trying to describe the taste of chocolate to
someone who has never tasted any sweets; or trying to describe hiking to a
person who has never left a room.
In the minds
of self-made millionaires, being self-made may equate with being self-taught,
and lead to being self-sufficient, or even arrogant. Unfortunately, even the
smartest people in the world can let their arrogance to blind them. One of the
saddest cases of arrogance is the death of Steve Jobs. When he learned he had
cancer he did not immediately take care of it using a traditional medical
approach, even though the cancer was treatable. But Steve so strongly believed
in his own power that he refused to follow doctors' advice. When he finally
gave up and turned to traditional medicine, it was too late. No doubt Steve
Jobs was not just smart, he was a genius. And he knew it. But he took it too
far.
