On Teaching Mathematics
Some thoughts on why we teach math the way we do, and why we probably shouldn't.
I've been teaching mathematics for over a decade now, and if there's one thing I've learned, it's that we're doing it all wrong. Not entirely wrong, mind you - we do manage to produce mathematicians, engineers, and scientists. But for every student who emerges with an appreciation for the subject, there are dozens who leave with nothing but trauma and a vague sense that they're “not a math person.”
The Problem with Procedure
Consider how we typically teach something like solving quadratic equations. We present the quadratic formula:
Students memorize it, plug in numbers, and get answers. They pass the test. Success? Not really. Ask them whythis formula works, or what it represents geometrically, and you'll get blank stares. We've taught them to follow a procedure without understanding - which is to say, we've taught them nothing of lasting value.
What We Should Do Instead
Mathematics is fundamentally about patterns, structures, and reasoning. When we reduce it to memorization and computation, we strip away everything that makes it beautiful and useful. Here's what I try to do instead:
- Start with problems, not solutions. Let students struggle with a question before giving them tools to answer it.
- Emphasize understanding over procedure.It's better to deeply understand one method than to memorize ten.
- Connect to intuition.Mathematics didn't fall from the sky; it was created by humans trying to understand the world.
- Embrace confusion.Being stuck is not failure - it's the beginning of learning.
A Closing Thought
The goal of mathematics education shouldn't be to produce human calculators. We have actual calculators for that. The goal should be to develop mathematical thinking: the ability to see patterns, construct arguments, and reason about abstract structures.
Until we change how we teach, we'll keep producing generations of students who can solve for but have no idea what actually represents.
