How Can We Break This?

I like this. The iPhone application RulerPhone will measure anything, in any photo, so long as the photo includes a credit card. It’s a great use of proportional reasoning, which, if pressed to name one, would be The Mathematical Skill I’d Most Like My Students To Retain After High School.

I added it to the What Can You Do With This? segment featuring The Bone Collector, which seemed like an obvious pair to me. In trying to find the best classroom entry point for this program, I can only think of the question, “How can we break this thing – trick it into giving an incorrect measurement?” I imagine someone can do better.

Shout Out To Sharers

I haven’t taught the second semester of Algebra 1 in three years, which means, right now, I wish my browser could search both Nick Hershman and Dan Greene’s sites at onceI mean, if I can trawl two hundred BitTorrent engines for Knight Rider re-runs in one keystroke …. Those guys do what I once did but now only talk about.

Did You Know?

Mark Zuckerberg:

If Facebook were a country, it would be the eighth most populated in the world, just ahead of Japan, Russia and Nigeria.

Marco Arment:

Right, except its demographics would be a bit skewed.

There would be no children and no elderly.

Half of the population would be dead, flopped over in their houses, with nobody noticing or caring. But they’re still counted in the census!

A quarter of the population would be marketing consultants yelling advertisements at everyone. They’re counted, too.

And nobody, including the government, would be making any money or producing much of lasting value.

Touche

Jeff Catania:

By the way, I don’t think you don’t have to *teach* conceptual curiosity as the human brain is naturally curious if we let it make connections between ideas to build concepts (constructivism) naturally. We only *think* we have to teach curiosity because student brains have been so dulled by procedures that they merely memorize without stimulating existing neural pathways.

Incidentally, I am in the middle of a post which may never see the light of blog, one which attempts to answer the question, “How should we capture and present digital media for classroom use?” and sets a personal record for most uses of the phrase “for lack of a better word.” The post has tangled around so many media, including but not limited to The Shield, The Wire, No Country For Old Men, Off-Road Algebra, Discovery Education streaming, Caché, David Mamet’s On Directing Film, What Can You Do With This?, Problem Pictures, Graphing Stories, and Dogme 95’s Vow of Chastity. This is fun and maddening, all at once.
