At 16, Albert Einstein wrote his first scientific
paper titled “The Investigation of the State of Aether in Magnetic
Fields.” This was the result of his famous gedanken experiment
in which he visually imagined chasing after a light beam. The insights he
gained from this thought experiment led to the development of his theory of
special relativity.
At 5,
Nikola Tesla informed his father that he would harness the
power of water. What resulted was his creation of a
water-powered egg beater. Tesla, who invented the basis of alternating current
(AC) power systems,
had the unusual talent to imagine his inventions entirely in his mind before
building them. He was apparently able to visualize and operate an entire engine
in his mind, testing each part to see which one would break first.
Thomas
Edison—famous for developing the light
bulb and more than 1,000 patents—was fascinated with mechanical
objects at an early age. He once said: “To invent, you need a good
imagination and a pile of junk.” He wasn’t joking. In his lab he wanted to have on hand “a
stock of almost every conceivable material.” According to an 1887 news
article, his lab was stocked with chemicals, screws, needles, cords, wires,
hair, silk, cocoons, hoofs, shark’s teeth, deer horns, cork, resin, varnish and
oil, ostrich feathers, amber, rubber, ores, minerals, and numerous other
things.
Einstein
imagined with his mind. Tesla imagined with his mind and built with his hands.
Edison imagined with both. They all had extraordinary spatial
talent—“the ability to generate, retain, retrieve, and transform
well-structured visual images.”
Spatial
thinking “finds meaning in the shape, size, orientation, location,
direction or trajectory, of objects,” and their relative positions, and “uses
the properties of space as a vehicle for structuring problems, for finding
answers, and for expressing solutions.” Spatial skill can be measured through
reliable and valid paper-and-pencil tests—primarily ones that assess three
dimensional mental visualization and rotation. Read more about examples of
items that measure spatial skill here.
But
despite the value of these kinds of skills, spatially talented students are, by and large, neglected.
Nearly a century ago, a talent search conducted by Lewis Terman used the highly
verbal Stanford-Binet in an attempt to discover the brightest kids in
California. This test identified a boy named Richard Nixon who would eventually
become the U.S. president, but two others would miss the cut likely because the
Stanford-Binet did not include a spatial test: William Shockley and Luis
Alvarez, who would go on to become famous physicists and win the Nobel Prize.
Today
talent searches often use the SAT and ACT which include math, verbal, and
writing sections, but do not include a spatial measure. All of the physicists
described above (and Tesla who could do integral calculus in his head) would
likely qualify today at least on the math section, and Edison would likely have
qualified on the verbal section due to his early love of reading. However,
there are many students who have high spatial talent but relatively lower math
and verbal talent who are likely missed by modern talent searches and therefore
fail to have their talent developed to the extent it could. Also, because
colleges use the SAT and ACT for selecting students, many high spatial students
likely do not make
it onto college campuses.
Nearly
every standardized test given to students today is heavily verbal and
mathematical. Students who have the high spatial and lower math/verbal
profile are therefore missed in nearly every school test and their talent
likely goes missed, and thus under-developed. What’s more, spatially
talented people are often less verbally fluent, and unlikely to be
very vocal. Finally, teachers are unlikely to
have a high spatial profile themselves (and typically have the
inverted profile of high verbal and lower math/spatial), and although they probably
do not intend to, they’re more likely to miss seeing talent in students who are
not very much like themselves.
So
what does the research tell us? In a study published in
the Journal of Educational Psychology, my colleagues and I
used longitudinal data from multiple data sets across 50 years to show that
spatial talent (in addition to math and verbal talent) is important for success
in STEM domains. The data came from the Study of Mathematically Precocious
Youth (SMPY), Project Talent, and the GRE. Of those students in the top 1
percent of spatial talent, roughly 70 percent were not in the top 1 percent in
either math or verbal talent—showing a large fraction of students having the
high spatial but lower math/verbal profile.
Now a
new study by Harrison Kell, David Lubinski, Camilla Benbow, and James Steiger
published in Psychological Science has made the connection
between early spatial talent and creativity in adult life even
stronger. The study, based on SMPY data, showed that spatial skill had an
increment of prediction over and above math and verbal skills (assessed at age
13) when looking at scholarly publications and patents—even those in STEM.
Can
We Enhance Spatial Skill?
So,
can enhancing
spatial thinking improve outcomes in STEM? A new study by
David Uttal, David Miller, and Nora Newcombe published in Current
Directions in Psychological Science notes that “a recent
quantitative synthesis of 206 spatial training studies found an average
training improvement of 0.47 standard deviations.” The authors suggest
that including spatial thinking in STEM curricula would “enhance the number of
Americans with the requisite cognitive skills to enter STEM careers.”
The
research is clear that spatial skill is important for STEM careers, and perhaps
we can even enhance spatial skill to help more people join the STEM fields.
What we need is research directed at understanding the best ways to develop the
talent of students who are high spatial, but relatively lower math/verbal.
Perhaps spatial video games and online learning coupled with hands on
interventions might help these students.
This
is what’s so great about the Maker
Movement and “Why Kids
Need to Tinker to Learn”: It will help encourage all students to
tinker, invent, and to use their hands to make things again. Certainly the
skills encouraged by the makers might be helpful to students who go on to
pursue STEM careers. But the movement probably will be most effective for
spatially talented students who have been neglected in our school systems.
One
student who felt neglected in the school system was researcher Matthew
Peterson. As a child, Peterson felt that he was drowning in words and numbers.
And in many ways he was, as he was identified as dyslexic—similar to Einstein
and Edison. This bothered him so much that today he has developed a way to teach math in
an entirely visual manner called ST Math.
Ultimately
we need to have the individual skill profile of each student matched to
individualized instruction tailored to them. We need to experiment in the
laboratory and classroom and conduct rigorous evaluations to find out what
actually works.
Redefining
and Valuing a Different Kind of Creativity
Today
we idolize creative actors, dancers, artists, musicians, and writers. But when
was the last time someone raved to you about a creative engineer or
mathematician? Why isn’t STEM considered creative or cool? Longitudinal
research has made a solid link between early spatial
talent and later creativity. Yet for whatever reason, we don’t
appreciate the highly creative nature of science, technology, engineering, and
mathematics.
It would seem impossible to argue that the theory of
relativity, alternating current, or the light bulb were not creative
innovations. And yet it is easy to forget that these advances fall squarely
in the STEM disciplines. Consider the device you are reading this article
from right now. Spatially talented people imagined it in their minds eye
and then they built it. Not everyone is going to be an Einstein, Tesla,
or Edison, but if we identify the many spatially talented students who have
been neglected in our school systems we might discover many brilliant kids who
are just waiting to develop their creative potential. We need to help them. After
all, we will ultimately depend on their visions to help create our future.
