Well, this seems to be the fall of hexagons. First Super Hexagon, and now…hexaflexagons!
I’m linking you to the most delightful thing I’ve seen all month: this series of absolutely charming videos about, well, hexaflexagons, these remarkable geometric shapes that pop up when you fold strips of paper in interesting ways. Huge kudos to Vi Hart, the hexaflexobsessive creator of these vids. Make sure you also watch Part 2 and the hilarious “Safety Guide”.
This is a great example of the possibilities YouTube has opened up for education. Characters, personalities, shapes, and properties all come across wonderfully, in beautiful color and at breakneck speed. It’s an extremely compelling introduction to a subject that could have been totally forbidding, and it’s especially well-suited to students with internet sensibilities. Teachers, take note. THIS is what visual aids can do — MUCH more effective than e.g. Powerpoint.
It doesn’t surprise me to learn Vi works for Khan Academy. This is my first personal experience with KA; I’m very curious now to look deeper at their offerings. What with this, Crash Course, and god knows what else — this whole web education thing has been moving FAST. This is exciting 🙂
