Story problem time!

image028Have a math problem:

A boat travels 60 kilometers upstream against the current in 5 hours.  The boat travels the same distance downstream in 3 hours.  What is the rate of the boat in still water?  What is the rate of the current?

If you are a reasonably educated person, you should be able to make headway with this fairly quickly:  the boat travels 12 km/h upstream (60/5) and 20 km/h downstream (60/3), which means that the boat’s speed in still water is the average of the upstream/downstream speeds, (20 + 12)/2 km/h, or 16 kilometers per hour, and the current is 4 km/h, which is the difference between either of the measured speeds and the average.

I spent about half an hour last night texting back and forth with a former student trying to work her through this problem and becoming more and more bewildered about what it was she didn’t get about it as the conversation went on.  She got the math– the math isn’t really that complicated, right?  Just division and an average.

What she didn’t get?  Rivers.  As it turns out, “downstream” and “upstream” are not terribly salient terms to kids who have lived in cities all their lives– and while, granted, the town I currently live in is actually called South Bend because the river bends south while wending through it, the terms “downstream” and “upstream” hadn’t managed to really ensconce themselves in her vocabulary as of yet.

This young lady is generally one of my brightest kids, mind you.  I’m not mocking her at all here, although maybe she deserves it a little bit– but the entire conversation got me thinking about how incredibly easy it is to write standardized test questions that you think are questions about math but turn out to hinge on some other kind of non-mathematical knowledge.  She could not wrap her head around the idea that the boat wasn’t going at its full speed “downstream” and that the current wasn’t slowing it down by (20-12) 8 km/h going upstream.  Which, of course, was one of the answers, because whenever anyone with half an ounce of sense writes a multiple choice test, one of the horrible tricks you do is thinking “Now, how might the students screw this up?” and then writing answers that match what they might have gotten if they did something predictable wrong.

The math?  She’s got it.  The geography lesson that the writer of the question no doubt didn’t realize was embedded into being able to get the question right?  Not so much.

I’ll talk more about this later; just wanted to get the thought down before it fell out of my head.  This is part of the longer series of posts I alluded to the other day before hell fell on my face and knocked me out for a couple of days, I think; I’ll get back to it soon.

In which I slowly go blind

imagesI’m spending the entire day crunching ISTEP scores and growth numbers and all sorts of other stuff, and alternately cursing myself, the Indiana State Board of Education, my boss, Microsoft Excel, human biology and math itself for the various frauds and iniquities being perpetrated on myself/my school/the state of education in general as I try and track down enough information to make what I’m doing useful to anybody.

I have discovered that the Windows version of Excel does not actually allow you to open two Excel documents in multiple windows.  For system software that is actually called Windows this seems like somewhat of a curious oversight.  Flipping back and forth is vastly annoying and I don’t like it one bit.  I’d prefer to not have to wait until I get home to do this on my Mac– there’s a reason I’m doing it at OtherJob– but it looks as if I might have to, because it’ll take a third of the time if I can just have everything open at once on my wonderful home setup, which features two monitors, one of which is a 27-incher, and not this teensy laptop screen.

Further aggravating me is the fact that the state appears to have made slightly different decisions about who counts and who doesn’t than I did when I put my initial numbers for my own students together back when I actually got the ISTEP data in the first place.  The low-growth kid who came in halfway through the year?  For some reason, counts.  The high-growth kid who I had for all but the first six days of the school year?  Didn’t.  Which shifts my overall numbers in a way I don’t like.

This don’ make no sense, and I’m wondering how exactly they decided who counts and who doesn’t, because length of enrollment doesn’t seem to be it.  Which is a whole ‘nother column I need to worry about if I’m going to keep track of it– and right now I don’t want to.

On the plus side, most of my grading is done.  I’m gonna take a break and read for at least an hour or so to let my eyes recover (from backlit tiny type to tiny type on paper, which… well, hopefully that’s a meaningful difference) and then I’ll see what else I can get done today.

What do people who don’t work two jobs on Saturday do on Saturday?

In which see if you can make me

whuteverFirst things first, because this post is going to be a bit of a downer and you deserve something at least a little funny:  I somehow managed to make it through the entire day with a massive hole in the crotch of my pants that I didn’t notice until I went to the bathroom during my last-hour prep period.  I assume no one else noticed it; I can’t imagine a universe in which I don’t get the hell mocked out of me for it if they did.

I did something I’ve never done today:  got pissed off and stormed out of a faculty meeting.

(Second disclaimer, and lemme put this right up at the top of this post so I’m not misunderstood:  I am manifestly not blaming the people who brought me the information that caused me to storm out of the faculty meeting today; I am not shooting the messengers and they were just doing their jobs.  Nor am I pissed at my boss.  The fact that at least two of the people involved may well read this is in no way related to the early disclaimer.  🙂  )

I’ll try and nutshell the background for those of you who aren’t teachers:  Every three weeks our students get a math test and a language arts test.  The tests are the same across grade levels– in other words, every seventh grader takes the same math test– and are supposed to be the same across the corporation as a whole, although I’ll admit right here and now that the math team at my school has altered individual questions that we thought were unfair or poorly written in some way and we didn’t bother getting permission for it.  We’re required to display the results of these tests on what are called data walls, because us educators like having complicated names for things.  I generated an Excel document for everyone that takes the test results and spits them out into pie charts that are broken down for the test as a whole and each individual math objective (generally, three) that is being tested.  The data is genuinely useful; I can keep track of where my kids are at relative to each other, to the grade as a whole, and I can see where my instruction doesn’t seem to be working– if my kids bomb one objective that the other teachers did well on, that may be an indication that I’m doing something wrong.

The data, again, is displayed on a class level in the classroom.  No individual scores, no names.  Just how each whole class did.

Apparently some lord high muckety-muck downtown has decided that that’s not good enough.  We’re now required to do “student-centered” data walls; the charts aren’t enough.

A “student-centered” data wall is one where the kids are posting their results on the wall– supposedly thinly veiled by using student numbers instead of names or some such shit like that.  The idea is that the kids are “aware of” and “own” their results, which somehow isn’t the case when I give them their tests, discuss them, and then discuss the class results with them, which I do every time I give a test.  We’re supposed to create some sort of bulletin board somewhere in the room where we can have the kids put their little name-tag thing up in the band (red, yellow, green) where their score landed.  In case it’s not obvious, green kids did great, yellow kids passed, red kids… didn’t.

I’ve talked about him before but I can’t find the post: my freshman year Algebra teacher was the worst goddamn teacher I’ve ever had in my entire life, and a large part of what made me hate him as much as I did was his practice of rearranging the seats after each test– by test score.  The kids who did the worst would be in the front row, all the way back to the kids with the highest scores, who ended up in the back.  The very worst score in the room would end up right in front of his desk.  And you’d stay there until the next test, when, more than likely (because he was a shit teacher) you’d get planted back in the front row again.

I spent a lot of time in the front row my freshman year of high school, and over twenty years later I can still feel the humiliation.  Note that I teach freshman algebra now, so this clearly wasn’t a result of my poor math abilities.  I literally teach the same class I flunked when this asshole taught it.  And I do it better than he did.

Anyway.

Here’s what this means:  you fail a math test in my class, not only do you fail a math test in my class, but you are supposed to get up and move a doohickey (that is supposedly, but not really, safely anonymized) so that not only do you get to be reminded that you failed every fucking time you walk in the room but everybody else gets to know about it too.  If you’re the only kid in a class who failed?  You get to be down there in the red zone all by yourgoddamnself and if the class doesn’t already know who the one kid who failed was they’re sure as hell going to do their best to find the fuck out.

I’m not doing this.

No.

Fuck you.  And fuck that.

I put my hand up and said, out loud where everybody could hear me, that I don’t like this goddamn job enough that I’m going to humiliate kids in order to keep it.  And then I left the meeting.

I don’t know what happened after I left; I don’t know if there were further riots or not.  But I’m putting my foot down on this one:  I will not do this.  Not under any fucking circumstances, period.  And if they don’t like it they can fire my two-time Teacher of the Year ass and I’ll go to a district that isn’t fucked in the fucking head.  Or just get the hell out of this demeaning fucking career altogether and leave the public school system to fucking rot like the Indiana public clearly wants it to anyway.  Fuck it.  My job isn’t worth this.  No.

In case you can’t tell, it was a long fucking day.
