Sounds like an
abomination—“teaching what you don’t know.” However, standing in front of a classroom
of 30-or-more students as an “authority” in a course entitled “Biology” lends
itself to this abomination. Studying the Mississippi state framework for my
subject (biology II), I was flabbergasted by the notion that the state thought
the in a lifetime let alone a semester I could cover an objective as broad and
as vague as: “Relate gene expression
(e.g., replication, transcription, translation) to protein structure and
function. (DOK 2)” (MS Framework 3c). My first response to such an objective
was, “people spend lifetimes studying just transcription, and the state expects
me to teach this to a group of teenagers in the space of a semester and still
wants me to cover other topics.” Little did I know that this was the smallest obstacle
I would overcome in attempting to construct a curriculum based on the state
framework.
My fear in teaching
gene expression was based on my broad knowledge base in the material; I was
afraid that I would have too much
material for my students to digest and process in the allotted time. Pruning
and prioritizing solved that problem. However, my unfounded fear in teaching
topics like transcription paled in comparison to the sheer horror I experienced
after I realized that the state expected me
to teach nine broadly based objectives on natural
selection. I don’t know the first thing about NATURAL SELECTION! There’s
Darwin then… I can talk day-and-night about transcription, translation, and
replication; but natural selection—let’s just say my content knowledge has room
for improvement. What am I going to do?
First,
save it for last! I am definitely not advocating this approach, but I waited
until the very last minute to teach natural selection. I hoped above hope that
we would not have time for it. The state does not test my course, so what is
the harm in skipping a competency? I plowed through every other competency. I
did not look at the state framework on natural selection until the last month
of the semester. It was a now-or-never moment. Teaching on a four-by-four
block, time goes quickly in a semester long course. I had to decide NOW if I
was going to cover natural selection. I decided to take to the challenge.
Second,
open the textbook. I barely use my course textbook, because—it’s terrible! My
students struggle reading a two-page article in the New York Times. The majority
of them read significantly below grade level.Taking this into consideration, why would my school district select a book
written on a college reading level? More than just the reading level the book’s
content is convoluted and boring. Thus far in the semester, I have only used
the textbook once in class. I usually consult the state framework to get an
idea of what my students are expected to learn, read the chapter(s) in the
assigned textbook on the topic, study other biology textbooks,
search the Internet for more resources on the topic, and lean heavily on my
previous knowledge. After this sometimes long and arduous process, I splice
together these resources to make my lesson plans and construct my own handouts
and guided notes sheets on the topic. However, this time my content background,
which is usually my strongest resource, is the weakest link. So, I turned to
the textbook. Although the content was dense and hard to comprehend; luckily,
my textbook had great figures, tables, and images on Darwin and natural
selection for my use.
Third,
scour the Internet. In my adventure in teaching, I have found some immensely
beneficial Internet resources for lesson plans, laboratory exercises, and
handouts.
However, my never-fail resources failed me this time. I could not find a
resource that could supplement my lack of subject knowledge. Then, a miracle—I
found a great National Geographic’s special about Darwin and natural selection
on YouTube conveniently broken up into 10-minute episodes.The special covered background on Darwin, information on his voyage on the
H.M.S. Beagle, Darwin’s specimens, fossil evidence, homologous structures,
population change, evolutionary trends, contributing scientists (such as Lyell
and Malthus), and more! That is when it all came together. I found a web hint
that allowed me to download YouTube clips on my computer, and, therefore,
circumvent my school’s block on YouTube.
Fourth,
pull it together. I watched the National Geographic’s special. I read the
chapters in the text. I dissected each subsection on natural selection covered
in the textbook, parsing out the key terms and concepts. I watched the special over-and-over
again until I picked it clean of concept connection questions that overlapped
with the subsections in the textbook. Subsequently, I crafted guided handout
sheets with critical diagrams accompanied by question on the clips. Now, I had
a plan! I taught a subsection each day followed by the accompanying clip. I
discovered a hands-on group activity that covered an additional section on
natural selection. This ensemble of resources helped differentiate instruction
based on learning styles, covering auditory (lecture), visual (clips), and
kinesthetic (activity) learners. In addition, each subsection had built in
remediation because the students heard the same or similar information covered
by the clips, the activity, and me.
Finally,
teach! The first Monday of my new unit, I jumped in headfirst. I knew I planned
as thoroughly as possible. I put the bell work up, wrote out the daily
objective, scribbled down the day’s schedule, and began. Students poured in and
the day went like every other day. Success! Hearing myself talk during the
lesson and reflecting on the day, I was even convinced that I knew what I was
talking about because miraculously I did! Did it all go exactly as planned? No,
but it never does. Did my students learn something they did not know before?
Yes.
I recognized
most of the angst that rose in my throat about teaching natural selection from
similar insecurities that I felt when I had to teach my first lesson this
summer. As a new teacher, fresh from undergraduate studies, I was emerging from
my role as a student, a novice to the daunting position as a teacher, an authority.
As an undergrad, yes, I was expected to have prior knowledge on the subject
matter, but my place in the classroom was based on the fact that I did not know
everything about the subject. I assumed a teacher’s sole purpose in the
classroom is to know everything. However, I have altered this standpoint drastically
in the few months that have been teaching.
Currently,
I understand that the learning never stops. There will always be a question
that a student poses that stumps me or a subject I do not yet fully understand.
My role in the classroom is to be a learning facilitator. The onus is not on me
to know everything and simply disclose my knowledge, but to work with my
students to play with and mold the subject matter to best suit them. With this
new outlook in mind, I now realize that I have to be my first student. I have
to re-teach/teach topics I am familiar with and topics I am less comfortable
with to myself, so I can try to anticipate my students’ needs and questions.
Although
preparing to teach natural selection was my biggest struggle, teaching natural
selection was my biggest success. My discomfort with the subject matter forced
me to find resources that captivated me and therefore were more likely to
captivate my students. I wrote plans with more details because I knew I had
very little background to fall back on. All in all, I think natural selection
was my best unit. If I could change anything about the planning process, I
would have made sure to consult with other teachers in my department. While I
am the only one currently teaching my subject, some collaboration with more
seasoned teachers in the department might have provided an additional resource.
I think some of my hesitation in asking my coworkers for help stemmed from the
fear I previously discussed. However, this is just another step in my learning
process.
