Kinesthesis in Science:
Where Red Rover Meets Quantum Mechanics
by Steve Dawson, Astronomy
Especially to the uninitiated,
learning science can be daunting. A primary contribution to this problem
is the fact that too often science lectures are overly formal, and they
employ a notation--namely the language of mathwhich ostensibly is
transparent to only an elite few. The belief behind my remedy to this
difficulty is that any physical problem, as well as all of the associated
formalism, can be rendered not only intelligible but even pleasurable
if the student first achieves a gut sense of the physical situation. Put
plainly, all of the math in any science class makes sense if the
student first has an intuitive mental picture of exactly what is going
on. Once this physical picture is in place, it serves as a framework
upon which the formal treatment can hang. And when the formal treatment
flows intelligibly with a student's gut picture of the situation, the
subsequent sense of insight is no less than thrilling.
So how to instill this essential
physical picture? I have found that getting students up out of their chairs
and physically acting out a problem, though it may feel ridiculous, is
an incredibly effective tool for instilling a gut-level physical intuition
about any scientific situation. Need to understand tides? Link hands and
form a circle to represent the Earth's hydrosphere. Pick volunteers for
the sun and the moon. Distort the human hydrosphere appropriately, then
let each student stand in the middle, being the Earth, physically
witnessing the succession of high and low tides. Though it may appear
laughable at first glance, actually acting out a given situation instills
the physical sense of why behind the formalism to come. Once this
instinct is in place, the rest of the discussion is well-motivated, and
the formalism will make sense. Moreover, it is very unlikely that a student
will forget one of these exercises. I have found that retention of material
so introduced is near perfect.
As an ancillary benefit, the
mere fact that the students are out of their seats during these human
models, moving and laughing and bumping into each other, serves extraordinarily
effectively to obliterate the impetus against asking questions in the
classroom. The students have already felt silly and seen their instructor
acting silly. In that respect, everyone is on equal footing, and the classroom
becomes a safe environment for verbalizing concerns. Additionally, the
enhanced physical and verbal interaction involved in kinesthetic modeling
enormously smoothes the implementation of cooperative learning, since
the "ice," so to speak, has long been broken.
To assess the effectiveness
of this technique, I did not need to look further than my students' exam
performance. Indeed, I found that students were distinctly more successful
when the exam material consisted of those areas I had covered with a kinesthetic
exercise. More notably, I was pleased to discover that this improvement
was particularly pronounced for exam questions that required critical,
creative thought as opposed to mere rote reproduction. Beyond this observation,
however, I offer the following anecdote: A student once told me that the
only reason she did not drop introductory astronomy is because we played
Red Rover during the first week's discussion. My goal was merely to break
the ice and to introduce Coulomb barriers; that student is now an astronomy
major. Of course, not every student in my section experienced so profound
an epiphany. Nevertheless, this anecdote is evidence not only of the pedagogical
success of kinesthetic modeling, but of the addictive pleasure which results
when one finds a method by which to truly understand the physical world.
