BRAIN-BASED
LEARNING
|
There
are some principles that drive learning. Every human being is
driven to search for meaning. We all create patterns from our
environment, and we all learn to some extent through interaction
with others. Because ours is a social brain, it's important to
build authentic relationships in the classroom and beyond. Complex
learning is enhanced by challenge and inhibited by threat. We
want to deeply engage learners with their purposes, values, and
interests (Caine in D'Arcangelo, 1998, pp. 23-24).

The
brain is the center for learning. Everyone knows that. The brain is
also very social. It wants to (typically) interact with other brains.
It is important, therefore, that educators understand the way the brain
functions as a brain and the manner in which the brain accesses and
uses the diverse bits and pieces of information that it encounters.
The
brain is always active. It is constantly accessing information and interpreting
its environment. The brain is continuously interacting with its surroundings
to "learn" how to function appropriately in the environment
in which it finds itself. The brain takes in information through the
senses (sight, smell, touch, taste, sound) and translates that information
into a response. Sometimes the response is appropriate; sometimes the
response is inappropriate.
The
brain never sleeps, but it needs rest. It rests, but does not "sleep;"
although at times, it goes into deep rest (or sleep).
There
are three main parts to the brain (the cerebrum, the cerebellum and
the brain stem) which are divided into two hemispheres connected by
a bridge called the corpus callosum. The cerebrum is the cognitive brain.
The cerebellum is the emotional brain. The cerebrum is where thinking
and learning take place. The cerebellum (in the amgydala and hippocampus)
is where memory (long term and short term) is stored and from which
our emotional responses (anger, fear, sorrow, love) come. The brain
stem provides an automatic "housekeeping" function. The brain
stem keeps the heart beating, tells the body to breathe, regulates cold
and warm, controls voice.
The cerebral hemisphere is
divided into the right hemisphere and the left hemisphere. The left
hemisphere helps us remember facts; the right hemisphere puts meaning
to those facts. The left hemisphere is analytical and logical. It likes
to deal with abstract information. The right hemisphere is random and
global. It likes information to be specific.
| Basically,
the brain is an oblong organ that weighs about three pounds. It
has an obvious fissure down the center that spearates it into two
hemispheres. Its covering, a wrinkled, one-quarter-inch-thick blanket
of cells, is called the cerebral cortex, and it is divided into
lobes, each of which performs many different functions. In the back
of the brain, the occipital lobes process visual stimuli. On the
sides near the ears, the temporal lobes process auditory stimuli.
Up a little higher and toward the back of the brain are the parietal
lobes where interpretation and integration of sensory stimuli occur.
Just behind your forehead are the frontal lobes where higher-level
thinking, problem solving, and planning for the futrue occur. Somewhere
in this entire cerebral cortex lies your ability to be consciously
aware of what you're thinking and doing. Researchers don't yet know
what consciousness is; it's a current focus of memory research (Wolfe
in D'Arcangelo, 1998, p. 21. |
A
key to remember when thinking about the brain is that each brain is
unique. Because of that uniqueness it processes information in ways
that makes sense to itself. What makes sense to one brain, may not make
sense to another brain, at least not in the same way.
The brain's uniqueness is
central to understanding brain-based learning. Each brain takes in the
same information and then processes that information randomly, i.e.,
in a way that makes sense to that brain, and only that brain. Each brain
constructs information that it takes in from its environment
in a way that makes sense to that brain only. The curriculum of a "brain-based"
classroom, then, should be thematic and integrated with a great deal
of interaction with others.
There is much written about
the brain and how it functions. Some of the foremost writers are Richard
Restak, Leslie Hart, Geoffrey and Renate Caine, Howard Gardner, Eric
Jensen, Robert Sylwester, Paul MacLean, Pat Wolfe, Marian Diamond. Articles
and books by these writers can be found in the resources folder. Also,
the following web sites are excellent resources about the brain:
