t's truly astonishing that the dominant model
for formal learning is still “sit and git.” It's not just astonishing; it's
embarrassing. Why do we persist when the evidence that lecture alone does not
cut it is so strong (Dolcourt, 2000; Slavin, 1994)?
The reason for the dissonance between what we
know and what we do may be traced back a hundred years. For decades, the
educational and scientific communities seemed to believe that thinking was
thinking and movement was movement, and each was as separate as could be.
Maverick scientists envisioned links between thinking and movement, but their
ideas gained little public support. Today we know better. This chapter
discusses the strong connections between physical education, movement, breaks,
recess, energizing activities, and improved cognition. It demonstrates that
movement can be an effective cognitive strategy to (1) strengthen learning, (2)
improve memory and retrieval, and (3) enhance learner motivation and morale.
In times of diminishing financial resources,
educators must make hard choices. Do dance, theater, recess, and physical
education belong in the curriculum? Can we afford to keep them in the budget?
Are they frills or fundamentals? What does brain research tell us about the
relationship between body and mind? If movement and learning are connected, we
should expect evidence to support the idea. In fact, there is plenty of
evidence.
Why is all this important? One of the
fundamental tenets of this book is that we have to teach with the brain in mind. Because movement is a natural
part of the school day, that movement will influence the
brains of students. It is essential that we explore the ways we are shaping
students' brains. To do so, let's look at some anatomical, imaging, cognitive,
and functional studies that suggest we ought to be supporting more movement in
the learning process, not less.
Evidence of Mind-Body Links
The first evidence of a linkage between mind and
body was scattered in various proposals over the past century (Schmahmann,
1997). Today, the evidence has become a groundswell, and most neuroscientists
agree that movement and cognition are powerfully connected.
Anatomical Evidence
The area of the brain most associated with motor
control is the cerebellum. It's located in the back of the brain, just under
the occipital lobe, and is about the size of a small fist. The cerebellum takes
up just one-tenth of the brain by volume, but it contains nearly half of all its neurons (Ivry & Fiez,
2000). This structure, densely packed with neurons, may be the most complex
part of the brain. In fact, it has some 40 million nerve fibers—40 times more
than even the highly complex optical tract. Those fibers feed information from
the cortex to the cerebellum, and they feed data back to the cortex. In fact,
most of the neural circuits from the cerebellum are “outbound,” influencing the
rest of the brain (Middleton & Strick, 1994). Peter Strick at the Veteran
Affairs Medical Center of Syracuse, New York, has documented another link. His
staff has traced a pathway from the cerebellum back to parts of the brain
involved in memory, attention, and spatial perception. Amazingly, the part of
the brain that processes movement is the same part of the brain that processes
learning (see Figure 4.1).
Evidence from Imaging
Techniques
New data, primarily from studies using
functional magnetic resonance imaging (fMRI), have provided support for
parallel roles of cognitive structures and movement structures such as the
cerebellum. We learn to predict (think about) our movements before we execute
them (move) so that we control them better (Flanagan, Vetter, Johansson, &
Wolpert, 2003). This ability suggests that all motor activity is preceded by
quick thought processes that set goals, analyze variables, predict outcomes,
and execute movements. Pulling this off requires widespread connections to all
sensory areas.
Various studies support the relationship between
movement and the visual system (Shulman et al., 1997), movement and the
language systems (Kim, Ugirbil, & Strick, 1994), movement and memory
(Desmond, Gabrielli, Wagner, Ginier, & Glover, 1997), and movement and
attention (Courchesne & Allen, 1997). These studies do not suggest that
there is movement in those functions. But they suggest a relationship with the
cerebellum in such mental processes as predicting, sequencing, ordering,
timing, and practicing or rehearsing a task before carrying it out. The
cerebellum can make predictive and corrective actions regardless of whether
it's dealing with a gross-motor task sequence or a mentally rehearsed task
sequence. In fact, the harder the task you ask of students, the greater the
cerebellar activity (Ivry, 1997). Taken as a whole, a solid body of evidence
shows a strong relationship between motor and cognitive processes.
Cognitive Evidence
Just how important is movement to learning? The
vestibular (inner ear) and cerebellar (motor activity) system is the first
sensory system to mature. In this system, the inner ear's semicircular canals
and the vestibular nuclei are an information-gathering and feedback source for
movements. Impulses travel through nerve tracts back and forth from the
cerebellum to the rest of the brain, including the visual system and the
sensory cortex. The vestibular nuclei are closely modulated by the cerebellum
and also activate the reticular activating system, near the top of the brain
stem. This area is critical to our attentional system, because it regulates
incoming sensory data. This interaction helps us keep our balance, turn
thoughts into actions, and coordinate movements. That's why there's value in
playground activities that stimulate inner-ear motion, like swinging, rolling,
and jumping. A complete routine might include spinning, crawling, rolling,
rocking, tumbling, and pointing. As noted in Chapter 2, Lyelle Palmer of Winona
State University has documented significant gains in attention and reading from
these stimulating activities (Palmer, 2003).
Functional Evidence
Currently, the MEDLINE database shows more than
33,000 scientific articles on the topic of exercise, and the vast majority of
them confirm its value. One study showed that people who exercise have far more
cortical mass than those who don't (Anderson, Eckburg, & Relucio, 2002).
Simple biology supports an obvious link between movement and learning. Oxygen
is essential for brain function, and enhanced blood flow increases the amount
of oxygen transported to the brain. Physical activity is a reliable way to increase
blood flow, and hence oxygen, to the brain.
In William Greenough's experiments at the
University of Illinois, rats that exercised in enriched environments had a
greater number of connections among neurons than those that didn't. They also
had more capillaries around the brain's neurons than sedentary rats (Greenough
& Anderson, 1991). Solid evidence suggests that even going for brisk walks
can elicit this state of arousal—meaning an increase in heart rate, EEG
activity, and more excitatory active brain chemicals (Saklofske & Kelly,
1992). In fact, if you haven't yet taken a break from reading this riveting
chapter, you might stand and stretch for a moment. Why? Standing can raise
heart rate (hence, blood flow) by as much as 5 to 8 percent in just seconds
(Krock & Hartung, 1992). And finally, here's a powerful research finding:
evidence from animal studies indicates that voluntary exercise influences gene
expression to improve learning and memory (Tong, Shen, Perreau, Balazs, &
Cotman, 2001). This improved pattern of gene expression enhances many factors
that support the encoding and transfer of data, synaptic structure, and the
activity and plasticity of neurons. All of these processes facilitate learning.
School Applications
An astonishingly high 68 percent of high school
students in the United States do not participate in a daily physical education
program (Grunbaum et al., 2002). Why should we be concerned? Because in the
same way that exercise shapes up the muscles, heart, lungs, and bones, it also
strengthens the basal ganglia, cerebellum, and corpus callosum—all key areas of
the brain. We know exercise fuels the brain with oxygen, but it also feeds it
neurotropins (high-nutrient chemical “packages”) to increase the number of
connections between neurons. Most astonishingly, exercise is known to increase
the baseline of new neuron growth. Rats grow more brain cells when they
exercise than when they don't exercise (Van Praag et al., 1999). In addition,
studies link this increased neurogenesis to increased cognition, better memory,
and reduced likelihood of depression (Kempermann, 2002).
Imagine that: Exercise may grow a better brain!
It suggests both a huge opportunity and the liability suffered by students who
don't get enough exercise. We may not be overstating the case to say that it's
educational malpractice when only about a third of K–12 students take part in a
daily physical education class.
Support for Recess,
Play, and Physical Education
Researcher Terrence Dwyer is one of many who
have conducted multiple studies suggesting that exercise supports success in
school. His research found that exercise improves classroom behavior and
academic performance (Dwyer, Sallis, Blizzard, Lazarus, & Dean, 2001) and
that even when an experimental group got four times more exercise per week than
a control group of their peers (375 minutes versus 90 minutes), their “loss” in
studying time did not translate into lower academic scores (Dwyer, Blizzard,
& Dean, 1996). His research further revealed that social skills improved in
the groups who exercised more. Other research (Donevan & Andrew, 1986) has
found that students who are engaged in daily physical education programs
consistently show not just superior motor fitness, but better academic
performance and a better attitude toward school than their students who do not
participate in daily P.E.
Human play has been studied quite rigorously.
Some studies suggest that students will boost academic learning from games and
other so-called “play” activities (Silverman, 1993). There are several theories
about why all mammals (including humans) play. But there is no controversy
around the notion that we do play, and that it is generally good for us. Many
early cognitive researchers ignored play, assuming it had nothing to do with
intellectual growth. They were dead wrong. Many play-oriented movements have
the capacity to improve cognition, including the following:
· Exercise play (aerobics, running, chasing, dance
routines).
· Rough-and-tumble play (soccer, football,
wrestling).
· Solitary play (doing puzzles, object
manipulation).
· Outdoor learning activities (digging, observing
insects).
· Stand and stretch activities (tai chi, Simon
Says).
· Group or team competitive games and activities
(relays, cheerleading).
· Constructive play (building with blocks, model
building).
· Exploratory play (hide and seek, scavenger
hunts, make-believe).
· Functional play (purposeful play, such as
practicing a new skill).
· Group noncompetitive games (earth ball).
· Individual competitive games (marbles, track and
field, hopscotch).
· Adventure or confidence play (ropes courses,
trust walks).
· Group noncompetitive activities (dance, drama).
· Walking excursions (outdoors, indoors).
Play, recess, and physical education are
essential for many brain-based (biological) reasons. Here are just some of the
benefits of exercise:
· It allows learners to make mistakes without
“lethal” consequences (with far less embarrassment and more fun than in a
traditional classroom situation).
· It enhances learning (Fordyce & Wehner,
1993).
· It improves the ability to handle stress by
“training” the body to recover faster from the quick surges of adrenaline
associated with demanding physical activity . . . and classroom environments.
· It triggers the release of BDNF, brain-derived
neurotrophic factor (Kesslak, Patrick, So, Cotman, & Gomez-Pinilla, 1998).
This natural substance enhances cognition by boosting the neurons' ability to
communicate with one another.
· It can enhance social skills, emotional
intelligence, and conflict resolution ability.
· Exercise may increase catecholamines (brain
chemicals such as norepinephrine and dopamine), which typically serve to
energize and elevate mood (Chaouloff, 1989).
The case for children doing something physical
every day is growing. Jenny Seham of the National Dance Institute (NDI) in New
York City says she has observed for years the measurable academic and social
results of schoolchildren who study dance. She notes the positive changes in
self-discipline, grades, and sense of purpose in life that her students demonstrate.
She's now in the process of quantifying the results of more than 1,500 kids who
dance weekly at NDI.
Although many educators know about the
connection between learning and movement, nearly as many dismiss the connection
once children get beyond 1st or 2nd grade. Yet the relationship between
movement and learning is so strong that it pervades all of life—and emotions
are intertwined into the mix as well. Educators generally consign movement,
emotion, and thinking to separate “compartments.” Students may feel awkward if
they want to express emotions or move around when teachers want them to be
still and think. Teachers need to realize that what the students are
experiencing is simply a healthy integration of mind and body (see Figure 4.2).

New Understandings of the Mind-Body Relationship
Additional Benefits
for Special-Needs Learners
Many teachers have found that programs that
include movement help learners with special needs. Several hypotheses may
explain this phenomenon. Many special-needs learners are stuck in
counterproductive mental states, and movement is a quick way to change them.
Second, movements, such as those involved in playing active games, will
activate the brain across a wide variety of areas. It may be the stimulation of
those neural networks that helps trigger some learning. For other students, it
may be the rise in energy, the increased blood flow, and the amines that put
them in a better mood to think and recall. Some routines that call for slower
movement can do the reverse, calming down students who are overactive, hence
supporting a state of concentration.
A study by Reynolds and colleagues (2003) found
that children with dyslexia were helped by a movement program. Those in the
intervention group showed significantly greater improvement in dexterity,
reading, verbal fluency, and semantic fluency than did the control group. The
exercising group also made substantial gains on national standardized tests of
reading, writing, and comprehension in comparison with students in the previous
year.
Practical Suggestions
Some of the smartest things teachers can do are
the simplest. When we keep students active, we keep their energy levels up and
provide their brains with the oxygen-rich blood needed for highest performance.
Teachers who insist that students remain seated during the entire class period
are not promoting optimal conditions for learning.
Educators should purposefully integrate movement
activities into everyday learning: not just hands-on classroom activities, but
also daily stretching, walks, dance, drama, seat-changing, energizers, and
physical education. The whole notion of using only logical thinking in, for
example, a mathematics class flies in the face of current brain research. In
fact, Larry Abraham in the Department of Kinesiology at the University of
Texas-Austin says, “Classroom teachers should have kids move for the same
reason that P.E. teachers have had kids count” (personal communication, 1997).
Brain-compatible learning means that educators should
weave math, geography, social skills, role-play, science, and physical
education together, along with movement, drama, and the arts. Don't wait for a
special event. Here are examples of easy-to-use strategies.
Goal setting on the move. Start class with an activity in which
everyone pairs up. Students can mime their goals or convey them by playing
charades with a partner, or the pairs can go for a short walk while setting
goals. Ask students to answer three focusing questions, such as these:
· What are my goals for today and this year?
· What do I need to do today and this week in this
class to reach my goals?
· Why is it important for me to reach my goals
today?
You can invent other questions or ask students to create some
of their own.
Drama and role-plays. Get your class used to daily or at least weekly role-plays.
Have students play charades to review main ideas. Students can do an
extemporaneous pantomime to dramatize a key point. Do one-minute commercials
adapted from television to advertise upcoming content or to review past
content.
Energizers. Energizer activities can (1) raise blood pressure and
epinephrine levels among drowsy learners, (2) reduce restlessness among antsy
learners, and (3) reinforce content. Use the body to measure things around the room
and report the results. For example, “This cabinet is 99 knuckles long.” Play a
Simon Says game with built-in content: “Simon says point to the south. Simon
says point to five different sources of information in this room.” Do team
jigsaw puzzles with huge, poster-sized mind maps. Have young students get up
and move around the room, touching seven colors on seven different objects in a
particular order. Teach a move-around system using memory cue words. For
example, “Stand in the place in the room where we first learned about . . .”
Quick games. Use ball-toss games for review, vocabulary building,
storytelling, or self-disclosure. Have students rewrite lyrics to familiar
songs in pairs or as a team. The new words to the song can provide a content
review. Then have the students perform the song with choreography. Get physical
in other ways, too. Play a tug-of-war game in which everyone chooses a partner
and a topic from a list of topics that every student has been learning about.
Each person forms an opinion about his or her topic. The goal is for each
student to convince a partner in 30 seconds why his or her topic is more
important. After the verbal debate, the pairs form two teams for a giant tug of
war for a physical challenge. All partners are on opposite sides.
Cross-laterals. Learn and use arm and leg crossover activities that can
force both brain hemispheres to “talk” to each other better. “Pat your head and
rub your belly” is an example of a crossover activity. Other examples include
marching in place while patting opposite knees, patting yourself on the
opposite shoulder, and touching opposite elbows or heels. Several books
highlight these activities, including Sensorcises by
Laurie Glazner and Smart Moves and The Dominance Factor by Carla Hannaford.
Stretching. To open class, or anytime that you and your students need
more oxygen, get everyone up to do some slow stretching. Ask students to lead
the whole group, or let teams do their own stretching. Allow learners more
mobility in the classroom during specific times. Give them errands to do, make
a jump rope available, or simply let them walk around the back of the classroom
as long as they do not disturb other students.
Physical education and recess. Budget cuts often target physical education
as “a frill.” That's a shame, because, as we have seen, good evidence indicates
that these activities make school interesting to many students, and they can
help boost academic performance. We're not talking about going overboard with
exercises. Thirty minutes a day, three to five days a week will do the job
(Tomporowski, 2003). Any school that has problems at recess or with physical
education should fix the problems, not throw out an important asset.
Teachers should also ensure that breaks include
some movement—no standing around at recess time! Breaks can include fast
walking, running, or high-energy play (McNaughten & Gabbard, 1993). The
breaks must last for 30 or 40 minutes to maximize the cognitive effects
(Gabbard & Shea, 1979). For breaks of that length, it may make sense to
alternate highly challenging activities with more relaxing ones. A short recess
arouses students and may leave them “hyper” and less able to concentrate. A
longer break engages high energy, but it cannot be sustained. Thus, a more
calm, restful state of relaxation should follow. This pattern allows the
students to focus better on the task at hand. Breaks at midday and early
afternoon provide a greater benefit to the students than an early morning
recess (McNaughten & Gabbard, 1993). Because longer breaks are more
valuable than shorter ones, timing may dictate that the midday break also be
used for lunch.
