# The Lesson and the Meta-lesson

I remember my first big Aha! moment. After many frustrating hours cramming for a math final, a visual analogy for several formulas hit me. The mess of symbols became a description, painting a scene in my mind.

"Argh, why couldn't they have explained it like this the first time?"

The difference between a semester of pain and instant understanding was one stupid, missing analogy. It still riles me up thinking about how close I came to missing the key concept (and disliking math).

In class there's the lesson about a specific formula, sure, but the meta-lesson is how well the experience went.

What worked? What didn't? How can we get more of the first and less of the second?

Over time, I realized individual topics were chances to explore what truly worked when learning. Not what a learning theorist or book said (Flashcards! Mnemonics! Just study harder!), but what actually worked for you.

A few of my scattered meta-lessons:

• Analogies, while imperfect, are a huge jump start. It's motivating to get the ball rolling and course correct along the way, vs. waiting to line things up perfectly.
• Nearly every explanation is improved with a visual or diagram.
• Humor and empathy put the reader at ease so they can tell you when they're actually confused (vs. mindless head nodding).
• Share the gotchas. The Wise Teacher hiding the 14 mistakes he made when learning the topic does students a disservice.

Every lesson is a chance to silently wonder "How well did that work?".

These days, I use ADEPT as a running checklist for how I get things to click:

This was pulled from actual frustrations (Why can't they share a plain-English version first? A diagram?) and I'm sure you'll have modifications of your own.

Don't just take a single lesson away from a lecture, article, or video. Think How well did that work for me? and build your learning approach around the best parts.

Happy math.
