Graphing Stories In Illinois

Most fun I’ve had all weekend is reading Jackie’s write-up of her class’ experience with that Graphing Stories unit I put together last school year.

We haven’t formally talked about slope yet, as for right now, we’re going for a more intuitive approach. I want them to understand slope as a rate of change, as opposed to thinking about slope as “m”.

It seemed only natural to toss in Dan Meyer’s Graphing Stories, so I brought it up during PLC time a few weeks ago. The other teachers loved it. Thus, Dan made an appearance in each of our classrooms this week. One teacher passed him off as her husband – she told her students they spend their weekends making math movies.

She shows me up, though, drawing a lot more discussion out of it than I did with my own lesson. (Heh … whoops.) She showed the one where I walk down the stairs …

… and had kids come up and draw the answer on the whiteboard. The first student didn’t account for the time my elevation was constant.

At that point, I jumped back in to help direct the conversation (some of them still try to get their points across by TALKING LOUDER). After a few minutes of discussing the first answer, we watched it a couple of more times. Then someone else volunteered to put up another.

Kids arguing over math. Man … I remember that. Can’t wait for that unit now. It’s gonna come earlier this year since this year I won’t spend three weeks getting knocked around trying to introduce it traditionally.

Jonathan, from Admin v. Doctorate:

Why can’t you manage your effort/energy better? It’s a little problem.

Two text-heavy slides from last year:

The same two slides, revised and expanded this year:

I can’t settle on what I know to be inferior.

I reckon we agree that some people shouldn’t teach. Maybe, like me, you think that’s pretty obvious.

What is less obvious to me, but what is also, honestly, no lie, probably true, is that I am one of them. I imagine this seems like a bit of pointless self-deprecation to most, but it’s an idea that’s made a lot of sense of a lot of frustration these last few weeks.

Like with those two slidedecks up there, I can’t settle on what I know to be inferior, no matter how much time it costs me. This is an attribute which, in my life, has always lived on the line between vice and virtue.

Once teaching and I met, however, it became fully vice. Teaching, like no other job I’ve worked, is greedy for that work ethic. It takes and doesn’t stop taking.

I used to think that relentlessness made me great for this job but now I’m not sure.

Assessment Part Deux Redux

The blogosphere’s been buzzin’ about assessment. (Not the NCLB kind.)

First, Marie, Rich, and Jackie have been asking some sharp questions on math assessment over in an earlier post.

Second, the Teacher Leaders Network blog is picking through the question, “How do you handle a student with an A on tests and an F on homework?”

My answer there, without even a little equivocation, is to pass her and then figure out why your homework is so totally inessential to class success. If you’re gutsy, you give her an A, but regardless you evaluate what it means to pass a student. Does it mean she did her homework, attended, participated in class discussion, raised her hand x times, wasn’t a discipline issue, brought baked goods on her assigned day, etc. etc., getting increasingly petty here. Basically, which of those behaviors is worth sandbagging a kid for a semester who knows the material, knows how to compute fractions, write persuasive essays, identify continents?

Third, Todd wrote an extraordinary post awhile back called “The Shrinking Educational Middle Class” which I’ve been meaning to pick up.

Todd sez, back in the day, you’d have histograms like this, with a bell-shaped distribution of grades (the graphics are his):

But that nowadays, the middle class is shrinking: the good grades get better, the bad grades get worse.

He’s right on; it’s a phenomenon that seems particularly exaggerated in low-performing populations. I’m going to proceed totally anecdotally here.
