I was doing a bit of random lunch-hour web-surfing, and came across a blog post by a swimming instructor. It starts with the eye-catching line “before you can teach something, you have to realize it’s hard”
The blogger writes about their insights into how (and how not) to teach swimming, and then wonders “how much this applies to other areas (teaching math in elementary school, for example?)” Having read the post, I’d say an awful lot does. Here’s my take on it.
