For this
assignment, I had to take something I use often but apply a consciousness to
the process that I don’t usually have.
Although Powerpoint is a common tool in my high school mathematics
classroom, I have to stop and pay attention to the elements of design that have
been articulated in Clark and Meyer. I
chose to use Powerpoint first (and then convert to Google slide) because the broadband internet at my
school becomes shaky during the day and having a Powerpoint is always a great idea.
They are working to expand, as we get more active educational technology
in the school, but having a Powerpoint is a “safer” choice in terms of ensuring
that you can use it in any given period, even if history classes are streaming
information on their classroom sets of iPads.
I struggle
with the “cognitive load reduction techniques” (Clark and Meyer, pg. 39). In
Powerpoints, for example, I like to put cute little cartoons or too many
concepts on one slide. This assignment made
me conscious of what students could process and my need to remain focused in
order to allow them to really understand the Pythagorean Theorem. I kept the visuals simple, but also wanted
the visual learners to be able to see the elements of triangle geometry
essential to the concepts.
I used
smaller chunks of information, looking to activate previous knowledge for my
students before proceeding to the new concepts.
This Powerpoint would be used after they have learned the concept of
area with a focus on practicality (such as finding the area of a room so that
they could price new flooring. For the
practice problem, which I used as a formative assessment, I wanted them to
understand the concept in a similar practical application. This also embeds the
“job specific context” (Clark and Meyer, pg .43) in this lesson, in order to
reduce the class math problem where formulas become randomly memorized. Students have a tendency to spit back
formulas but not understand why or how they work. For math understanding to be a life-long
problem solving skill, students must understand the how and why of formulas,
even something as basic as the Pythagorean Theorem.
