Can Computers Replace Teachers?
- Steve Jobs didn’t think that technology alone could fix what ails
American education. It’s worth remembering that in the wake of last
week’s breathless coverage of Apple’s new iBooks platform, which the
company promises will radically change how students use and experience
textbooks. Under Apple’s plan, companies and individuals will be able
to self-publish textbooks, ideally creating a wider array of content.
Students will be able to download and use these books on their iPad
much like they would use a regular textbook — including highlighting
passages, making notes and pulling out passages or chapters that are
especially important to them. Apple says it also plans to cap the price
of textbooks available through iBooks at $14.99, a significant
departure from the price of many textbooks now.
- Critics were quick to pounce that Apple wasn’t being revolutionary
enough. Former school superintendent and current ed-tech investor Tom
Vander Ark chided Apple for not thinking past textbooks, which he
considers hopelessly 20th century. Others worried that Apple’s real
goal wasn’t to open up the textbook industry but to control it and
profit from it through restrictive licensing agreements and a platform
that dominates the market. I’m sure the for-profit company’s
shareholders will be horrified at that news.
- Let’s slow down. Textbooks or tools that look a lot like textbooks
aren’t going anywhere anytime soon. And since high quality educational
material isn’t cheap to generate, simply tearing down distribution
barriers will only go so far in reducing the costs of producing good
content. Lost in the heated claims, however, is a more fundamental
question: what have educational technology efforts accomplished to date
and what should we expect?
- As a field, education is easily seduced by technological promises.
Textbooks? Thomas Edison saw movies as way to replace them. In a
prelude to today’s debates, the phonograph and film strip were lauded
as technologies that could replace live teaching. These days,
conservatives are in love with the idea that technology will not only
shrink the number of in-classroom teachers but render the teachers’
unions obsolete.
- The experience to date is less grandiose and more worrisome
considering the billions that have been spent on technology in schools
in the past few decades. Interactive whiteboards have been around since
the early 1990s and done little to transform how teachers teach, and
computers are often unaligned with classroom instruction, even though
90% of classrooms around the country have them. Still, according to
Department of Education data from 2009, just 61% of students use
computers to prepare texts “sometimes or often” and just 45% do more
complicated tasks, for instance to “solve problems, analyze data, or
perform calculations” on a regular basis.
- Usage aside, there is scant evidence that technology is improving
learning — even the cheerleaders are reduced to arguing that various
education technology tools are obvious rather than supported by much
evidence. And when you watch, say, high school students use the
Internet to prepare research papers, it’s questionable whether
technology — especially when coupled with poorly trained teachers —
isn’t doing more to enable the superficial rather than open up richer
veins of information for students.
- The reasons for the slow pace of change are as obvious as they are
stubborn. Altering classroom and school practice in our wildly
decentralized education system is always a slow process. Many teachers
are not familiar with technology or how to use it in the classroom, and
high-quality training programs — either in schools of education or as
part of a teachers’ ongoing professional development — are rare. As
always, there are few guides for educators to determine which products
are any good.
- There is, of course, still promise in education technology. When
Dreambox Learning, an online math program for elementary-aged students,
offered me a free trial to check it out, I did what I usually do with
new educational tools — I put it to the ultimate panel of critics: my
kids. Dreambox, which just this week announced a new series of lessons
aligned to the nascent Common Core standards and free licenses for
every school in the country, combines real content with an interactive
format so kids are learning even when they think they’re just playing
games. I’ve looked at a variety of products, and it’s one of the best
in terms of powerful instruction. In a short time, it substantially
boosted my kids’ math achievement. (They have a great teacher, too.) As
for engagement? Maybe too much. One of my daughters woke me up at 5 am
the other day because she wanted to do math.
- Yet even a top-shelf product can only augment live teaching. Despite
Dreambox’s overall good functionality, there are places where students
can become frustrated — not because they don’t know how to do the
underlying math, but because the directions for the online activity are
confusing. Likewise, technology is bringing back in vogue the idea of
the “flipped classroom” with the teacher acting as a “guide on the
side” rather than the primary source of instruction. I say back in
vogue because, ironically, talk of devaluing the teacher as content
provider has been a fixture of progressive education thought for a
century. Another variation of the flipped-classroom idea is to use
technology to explain concepts at home and use classroom time
differently. Again, a lot of potential, but only with keen attention to
instructional quality. Much of the online content available today
merely replicates the lame instruction already available in too many of
our nation’s schools.
- As a parent and an analyst, I want technology that includes rich
content or enables students to access it. And I want technologies that
are engaging for students but actually teach them something. Plenty of
applications err on one side or the other. And as with lots of offline
schoolwork, there are time wasters that aren’t helping anyone learn
much of anything. If anyone tells you an ed tech tool has “gaming
elements,” make sure it’s not just a game.
- American education desperately needs an overhaul that goes far
beyond upgrading computers in the classroom. It’s the last major
American field relatively untouched by technology. But Jobs was right:
technology by itself won’t fix what ails our schools. He saw teachers’
unions and archaic practices as the big barriers. Perhaps, but I’d
argue they are symptoms of our larger inattention to instructional
quality. The bells and whistles of technology, for all its promise, are
distracting us from this mundane but essential reality.
