You’re getting on my last NERV!

We’ve had the opportunity to discuss quite a lot of things in the Math of Sports and Games class.  Right now, they’re working on a project on NERV. 

NERV stands for net expected run value (see here, for more).   It’s a great lesson to talk about that utilizes probability and expected value in a real tangible way.  We’re using math to better create strategies to cause baseball teams to win.  How is that not a cool thing? 

No longer is math a series of steps, but rather a tool that is used to increase success (we’re looking at success on the baseball field, but I think the kids will start to see it as a tool to increase success in other ways too).

First week of school

One week (a partial week) is in the books, and this school year looks to be an interesting one.   I introduced SBG to my Calculus class.  We haven’t yet taken a standards assessment (it will be next Tuesday), so they haven’t made any real judgments on the system.  They seem skeptical, but we’ll see how things go.   I’m not used to giving assessments as often as it will be needed with SBG, so it will be different for me as well.

The Math of Sports and Games class has been pretty fun so far.  On the first day of class, I presented them the classic Monty Hall problem. I asked them what they would do, and I then showed them this video clip from the movie 21 (by the way, that’s the best website for math video clips anywhere, so check it).

They were skeptical even after watching it.  The guy sounded smart, but they weren’t sure what to make of it.  I made no comments on anything at this point in time.

At this point, I WANTED to have the kids use their iPads to perform a simulation of the Monty Hall question (I like to program).  However, they decided not to give iPads to the iPad-centered class, so we couldn’t do it.  Instead, I gave them 3 post-its and a little piece of paper and had them simulate it in a “hands-on” method with another classmate.

They recorded their answers and we pooled the results to discuss.

It went pretty well, but the fact that a fellow classmate was choosing where to put it gave us some skewed results (since it wasn’t truly random).
