ID104: Objective Stacked Bars

I tried to impress on them the need to make this a bit more scientific. How would we make a stacked bar from hard data? After some consultation with colossal T.A. Katy I figured the best scientific analog to my deeply-unscientific, pretty-circle shtick was Gardner’s Multiple Intelligences Test.

I printed out copies. It’s short. We all took ’em. We talked about what the intelligences meant. (No one knew what “intrapersonal” meant, just for example.) Whenever possible, ask them what they scored on something or what they think about something. That frictional release is 90% of my class management right there.For those still keeping track, my class management breaks down 90% standing at the door and 90% call-and-response. Yes, I teach your children math.

I showed them how to turn their scores — let’s say a student’s kinesthetic score was 8/26 — into fractions. My patter would almost always run like this: “If the bar was broken into 26 pieces, this’d be easy. You’d just shade eight of them. But it isn’t. It’s in a package of 100 pieces.” Then I’d show ’em how to set up the proportion.

Stacked Bar Template II (this one has 100 tic marks)It seems almost insane to me now that I didn’t include them at first. My first class, I had them measuring the height of the bar (13 cm.) and figuring that into the proportion. Utterly insane. Painful. It was a fun trip, though, after I re-printed the stacked bars with 100 tic marks.
