New Research
Probes Frontiers
Of Tech Learning
By Benjamin Herold
Chicago
Academic researchers have begun
formally examining the latest frontiers
in educational technology use.
Their focus: studying how emerging
technologies that facilitate new types
of hands-on student learning impact
teaching, learning, and classroom
engagement. They're also looking at
tech-enabled instructional practices
that provide new windows in children's
mental problem-solving processes.
"We are exploring new territory," said
Michael Tscholl, a postdoctoral researcher
at the University of Wisconsin-Madison.
He recently helped conduct a study of
MEteor, a "whole-body, mixed-reality
immersive simulation" funded by the
National Science Foundation in the
hope of improving students' grasp of
commonly misunderstood concepts in
planetary physics.
Other research presented recently at
the annual meeting of the American
Educational Research Association, held
here April 16-20, examined "connected
gardening," the use of digital-tablet
screen-casting technology to plumb
students' often-invisible strategies for
solving math problems, and the push to
get children creating their own digital
learning games.
What follows are descriptions of four
different researchers' explorations of
such new uses of ed tech, as presented at
the aera gathering.
A student uses a simulation game called MEteor at a science center in Orlando, Fla. The game uses the principles of "embodied cognition" to teach planetary physics.
Merging Physical Movement and Virtual Understanding
Most students harbor fundamental misA
superior strategy, some researchers beunderstandings
about how forces such as
gravity and acceleration operate in outer
space, said Michael Tscholl, the University
of Wisconsin researcher.
That's because their beliefs about physics
tend to be based on their experiences
in their own bodies, he said. A 7th grader
living on earth, for example, needs energy
and force in order to move. But the opposite
is true for an object in space, which, once
launched, will continue moving forever,
until a countervailing force provides the energy
to stop it.
For decades, Mr. Tscholl said, teachers
have tried to overcome their students' misunderstandings
around such concepts by
having them manipulate symbols on paper,
or on computer screens.
But now, he said, that approach is often
regarded as ineffective.
lieve, would encourage educators to embrace
"embodied cognition," in which students are
provided with opportunities for physical
activities specifically designed to get them
moving in ways that will help them to learn
new ideas-and to unlearn some of what
they already (incorrectly) believe.
For example: MEteor, a room-size "simulation
environment" that calls to mind a
space-age version of the popular arcade
video game Dance Dance Revolution.
In MEteor, planets and other space objects
are projected on the floor and walls. The students
must predict the trajectory of an object
moving through space by physically moving
along the path they think a meteor (projected
on the floor) will travel. Laser-scanning
technology tracks their movements,
offering real-time feedback on whether
their predictions are correct. Based on that
feedback, students adapt their beliefs about
scientific principles, then adjust their movements
to reflect what they are learning.
In an experimental study involving
113 middle schoolers, the students who
used the simulator (as opposed to a desktop-computer
version of the same task)
demonstrated greater gains in their understanding
of physics concepts such as
gravitational acceleration.
They also were significantly more engaged,
concentrated better on the task at
hand, and reported a greater sense of feeling
like a scientist themselves.
And they had more fun.
"What is quite clear is that students are
scared of symbolic representations," Mr.
Tscholl said. "We are trying to achieve
something really big."
The study is currently under review for
publication. n
Designing a Novel Way to Peek Inside
Students' Mathematical Thinking
Many teachers already use screen-casting
technology to capture the work displayed
on digital devices and create lectures and
tutorials for their students.
But researchers at San Diego State University
and the University of California,
Davis, believe formative assessment could
be an even more powerful use of such
technology. One potential use: getting students
to create a multilayered record of
their thinking while attempting to solve
math problems.
Such an approach could help teachers
"go beyond determining whether
students correctly solved the problem,
to understand why students solved the
problem the way they did," wrote Melissa
M. Soto and Rebecca Ambrose in an asyet
unpublished paper, presented at the
research conference.
To test these beliefs, Ms. Soto and Ms.
Ambrose are conducting an ongoing study.
During an early experiment, 10 students in
grades 3-6 in California and Florida were
asked to solve several multiplication, division,
and fraction problems using an app
called Explain Everything. The children
generated screencasts of their problemsolving
processes. They also recorded themselves
as they verbally explained their work.
The researchers observed and interviewed
the students, then analyzed the
resulting data and the student screencasts
using an original rubric. Their focus was
on determining whether the students' verbal
explanations of their thinking reflected
the problem-solving strategies they actually
used, and whether those strategies led
to a correct solution.
Particularly noteworthy, Ms. Soto and
Ms. Ambrose wrote, were those instances
when "students' thinking went astray,
or when their verbalizations and notations
did not align."
Researchers at San Diego
State University and the
University of California,
Davis, are conducting an
ongoing study of how
educators can use
"screen-casting" to capture
multilayered records of
students' thinking while
they are attempting to solve
math problems.
One student, for example, incorrectly
solved a word problem that required division.
By reviewing the screencast of the
student's work in conjunction with her
audio-recorded narration, the researchers
were able to ascertain that the student
had used a sound problem-solving
strategy, but made an arithmetic error
caused in part by her haste to finish
quickly (and thus demonstrate that she
was "good at math").
Without the screencast, the authors
wrote, "it would have been difficult to pinpoint
where exactly the mismatch took
place, and it could have been incorrectly
concluded that [the student] did not understand
the problem from the start."
Expanded use of screen-casting for
formative assessment, Ms. Soto and Ms.
Ambrose concluded, has "the potential
to transform the learning environment
by allowing teachers to gain more insight
into their students' mathematical
thinking."
They hope to submit their study for publication
later this year. n
