"Oh my god, I love you! Thank you so much!!!!"

I'm the recipient of a lot of comments like that; they're just not meant for me.

I posted a few math videos casually created by a talented teacher two years ago - just as samples for a concept demo for personalized education. So by accident of mistaken identity, I've vicariously watched a stream of "thank you" comments from appreciative students.

It's inspiring to see the multiplier on this teacher's impact. Her 9-minute instruction on dividing polynomials would have previously benefited the 30 kids in her class that day. Now, she's helping more than 30 each day - for a cool 36,500% increase in the reach of her talent. And that doesn't even include the viewership of the same video subsequently posted on her own YouTube account. Amazing.

Plus, the video "Hot Spots" seem like a really helpful feedback loop. Where did I engage them? Where did I lose them? What topics were most helpful? The loss of that pedagogical feedback loop typical in two-way classroom exchanges with 30 kids must be at least partially mitigated by the much larger sampling of attention among thousands of kids.

Maybe soon those same kids will benefit from a new kind of final exam review - where they tune into an automatically generated compendium of Hot Spots on any subject from the best teachers in the world. Anyone in Education working on that?

p.s. - if anyone knows how to merge a YouTube video in one account with a copy of the same video in another account, please let me know. I'd like to reunite the recording with the artist without losing any fans.
