Post by Joe Buck: Joe is in his 31st year of teaching
Mathematics at Bettendorf High School.
He still owns his now yellowing copies of the Core Standards for
Mathematics Content and Core Standards for Mathematical Practices that were
developed by a large group of college and high school teachers, textbook and
standardized test writers, and members of the mathematics, business and
scientific communities. You can follow him on twitter @josfbuck
Back in the Spring of 1985, our students voted on a slate of
superlatives. Best this - Most likely
that. They included some teacher
superlatives, too, one of which was “Most likely to be teaching at
Bettendorf High School in the year 2050”.
I was doubly amused by the two teachers who ended up tied for the “award”. One was a fixture, who at an age approaching
seventy was not going to be there by the Fall of 1985, let alone
2050. The other was me. As a first year teacher, there was at least a
chance that I would live until 2050, but I was quite certain that I
would soon be teaching at the college level and be a distant memory around this
place.
Now I will most certainly not be at BHS in 2050. But what happened to that college goal? Turns out I loved teaching high school
mathematics. And, by the way, I still
do! I love the beauty of introducing
kids to something as simple as Euler’s Formula (shown above) which can be
understood best after mastering Taylor Series at the end of Calculus. Or the infinite complexity and
self-similarity of the Mandelbrot Set (seen below). I love when something complicated looking can
be understood as simple. “Oh,
you mean you just… ?” I also love when something that looked
simple turns out to be so much more interesting.
Just like my “favorite tie”
is the one I am wearing today, so my favorite time to be teaching is
right now. People often assume that my
field has been set for thousands of years and is fixed and unchanging. Yet the first crude pictures of that
Mandelbrot Set were only developed a few years before the first year of my
career. When I was in high school, I was
taught about logarithms and my teacher showed us how we could use them to
understand how to work with a slide rule to “easily”
make arithmetic calculations. Of
course, calculators were already pretty widely available, so he didn’t
actually make us learn how to use those slide rules. That would have been the traditional
course at the time, but it would have also been silly. Technology advances continue to make a
difference in what is most important for everyone to know from those centuries
of mathematics. There is so much math happening fresh every day. Much of it is completely understandable by
teenagers. And even when the math is
Algebra and Geometry, where most of the specific things we decide are important
(or Core, if I can use that word without it being a political statement) have
been around for centuries, we learn more and more each year about how the brain
works and how learning happens, making right now the best time to be
teaching. (And next year it will be
then, we will have learned so much more about what is most effective.)
I have a student teacher this year. He is enthusiastic, energetic, and excited
about helping kids learn mathematics. I
hope for him that thirty years from now, the rush of helping kids see something
today that they did not know yesterday, then understand it tomorrow, and master
it by next week will still be just as exciting as it is right now, and as it
was thirty years ago.
