Lesson 1 introduced us to the importance
of experience on the development of a healthy brain. I learned several
new concepts and was challenged to think outside of the current educational box
to account for our brain's natural propensity for learning and growth.
According to Children
and Brain Development: What We Know About How Children Learn,
prepared by Judith Graham, heredity (or nature) determines the number of
neurons a child is born with and their basic structure. A majority
of the neurons in a developed brain are actually present at birth, but it is
the number of synaptic connections between these neurons that explode
exponentially during the first 2 years of a child’s life. During
sensitive periods, certain synapses are more likely to be shaped and
developed. Experience serves to strengthen those synapses being more
utilized, or eliminate those synapses that are not being used. It is
important to understand not only these sensitive periods, but how to best
develop these synapses to encourage their becoming part of the permanent
foundation of the brain’s architecture.
Taking what was
learned in the video “The Changing Brain” and relating it to the position taken
by Eric Jensen in “Brain-Based Learning,” it is easy to see how so much of
today’s educational system gets it wrong when it comes to naturally encouraging
the full development of the human brain by maximizing the potential present
during sensitive periods of the brain’s growth. Brain-based learning is
the implementation of strategies and principles in accordance with how the
brain naturally is wired to learn. Unfortunately, educators are too
bogged down by ineffective programs and bureaucracy to effectively implement
these strategies in the classroom.
As
a teacher, I will be more cognizant of the effect experiences have on the
development of my students’ brain architecture and their ability to develop to
their full potential. Knowing that brain development is different for every
student based on his or her experiences during early childhood will enable me
to be more sensitive to the cognitive and behavioral differences among my
students. It will also inspire me to create those types of experiences
that will foster positive growth in the brain and create stronger brain
architecture for future development.Fostering
healthy experiences inside the classroom is only a part of the battle, however.
By being aware of sensitive periods in which my students will have the
maximum ability to create long-lasting brain growth in particular areas, I can
harness their natural potential and help them more fully realize their ultimate
potential. Also, it may be important for me to evaluate the experiences
each student has with other students or adults, experiences on the playground,
and even experiences at home, as well, to ensure that the healthiest
development can occur.
