New math; old math? I have no children and I am not in frequent contact with any parents of school-age children but with what I’ve seen about so-called Common Core math I see a parallel to Rube Goldberg (1883-1970) who created devices deliberately over-engineered to take 20 or more steps to accomplish a two-step task. Goldberg was an American cartoonist and inventor. His “cartoons” humorously described a complicated series of steps to achieve a very simple result. Just like the “New Math” in which I see no humor.
Enter
William of Ockham, an English friar, philosopher and theologian. Ockham (c.
1287-1347) is credited with developing a problem-solving principle which held,
generally, that when there are multiple hypotheses, the one needing the fewest
assumptions is likely the correct one. The fewer assumptions, the greater the
likelihood of repeating the same result which is related to the empirical
nature of The Scientific Method – testability and repeatability. This is the “Old
Math”.
Educators
tout the value of Common Core as bringing to students a broader exposure,
immediately, to the underlying principles of Mathematics. My bias will show
when I say there’s absolutely nothing wrong with the old way. Even the best Forensic
experts in any field learned their craft by starting with the basics
progressing layer by layer to broader knowledge and understanding.
Writers
are advised to begin their stories in
medias res (in the middle of things). In
medias res is definitely not the best way to teach math. Even Euclid of
Alexandria, the Greek mathematician regarded as the father of geometry, determined
that a straight line is the shortest distance between two points. Start at the
beginning point and progress to the next without swerving. To dapple in
arithmetic, algebra and perhaps calculus, simultaneously, before mastering the
basics seems ludicrous.
I
learned math the old way – arithmetic, geometry, algebra, trigonometry,
logarithms, and calculus. I can solve most math problems easier than I can open
pilfer-proof plastic packaging. I can see the product but I can’t get to it
before employing tools and cutting myself on the sharp plastic edge.
Sometimes
an old dog’s old tricks are more valuable than the new tricks you’re trying to
teach it.
