Sure, I can do that

Spent the last half hour talking a high school sophomore off the ledge, which is what you expect to happen when you teach 8th grade. She’s in Algebra 2 right now, which technically I’m legally allowed to teach, and I can absolutely handle both the mathematics behind and the explanation of that second inequality up there, but she swears up and down they haven’t been working with quadratics at all. That’s the second question of the two she asked me about, and the first of the other pair of inequalities looks like this:

…which is a reasonably tricky PEMDAS problem (a parenthetical with an exponent and a multiplier on it is the stuff of 10,000-comment internet videos) even before you get to graphing quadratics by hand, which I’m capable of with intense concentration but may not be great about explaining very well at the moment. Both pairs of inequalities have a simple linear inequality and a quadrilateral, and long story short, I’m not convinced her teacher gave her the assignment that he meant to. On an e-learning day, no less? You serious, man?

This isn’t a kid who’s going to forget that they just spent a month on quadratics or something like that, by the way. She’s bright. And she took a picture of one of her assignments from last week, which was graphing absolute values. The leap in difficulty from graphing absolute values on a number line to graphing systems of inequalities where one inequality is linear and the other is a PEMDAS nightmare that turns into a quadratic is … stark. There’s gotta be something else going on here.

Anyway, we’ve got the day off tomorrow again, which was the right decision. It’s been 20 below or worse all day, and it’s supposed to warm up significantly tomorrow, but at 8:00 in the morning it’s still going to be 20 below, and even after a two-hour delay it’s still going to be fifteen below– the temperature isn’t going to be conducive to human life until after noon, and you don’t make kids walk to school in subzero wind chills, especially when a lot of them don’t have coats. We will not lose Thursday or Friday, as it will be regular Midwest January cold and not the kind that has you cursing God.

The kids will, of course, find a way to make Thursday and Friday feel like a long week.

Well, crap

I can’t get WordPress to load from my desktop for some reason, but it’s working for my phone, so … yeah. God forbid I not post something.

(Site loads on computer)

I’m gonna take another practice test tomorrow. If I had gotten everything right that I either already knew or feel like I nailed down today, I’d have gotten a 55/66, which is a clean and easy pass. The other 11 are calculus problems and hopefully guessing will get me two or three of them. If I do well tomorrow, I’m definitely taking this for real next week.

In which it looks like I can do this

I ended up having some spare time this afternoon, and I found a free practice test online through the same people that sold me my study guide (so I figure it’s at least reasonably reputable) so I went ahead and took it, and if I’m understanding the scoring methodology correctly … it looks like I passed, although not exactly with flying colors– I got 42/66 questions right, or 63.34%, for a final score of 163, and a 159 is a pass in Indiana. I could have gotten a 39 and still passed, so I had a three-question cushion on my first try.

Now, granted, no one is ever going to look at my Praxis score again after I’ve passed the thing, so it really doesn’t matter if I pass it by the skin of my teeth or by flying colors, but I want a little bit more of a cushion than that. I was able to go through the practice test after taking it, and I printed out two categories of questions: questions I had gotten wrong, and questions that I got right but I know good and well that I got right by being lucky. That gave me about 27-30 questions to study tomorrow; in there are a handful that I absolutely shouldn’t have gotten wrong, including one thing I’ve taught fairly recently (!!!) and one where I just flat-out calculated something incorrectly and didn’t notice it, but I figure being fully confident of over half the test is better than I expected going in. I missed nearly all of the calculus questions, of course, but I got a couple of the trigonometry ones right without guessing and there were one or two of the harder ones where I was guessing between, say, two answers instead of all four and managed to get the right one. I figure I’m going to do this twice more– I’ll study my wrong answers tomorrow and see which ones I can get comfortable with (some are a matter of just not understanding certain kinds of notation, so those will be easy points) and do another practice test on Thursday, then maybe one more over the weekend, and if my numbers move in the right direction I don’t see why I can’t move ahead with the real thing next week sometime. Which, on one hand, will wipe out one of my big plans for June, but on the other hand will let me focus more on Arabic, curricular stuff, and Spanish.

The other thing I need to make sure I understand is the actual rules for taking a Praxis from home. I know they have a proctor monitoring you but I’m not sure what the tech rules are and I suspect on at least two questions I may have broken a rule, depending on how picky they are. This organization has made me incandescently angry with them on multiple occasions so I need to make sure I’m prepared for literally anything. Hopefully things go smoothly, but I need to prepare for them not to.

Some bits and bobs

My head’s all over the place right now, so let’s do a bullet list.

  • Indiana voted on Tuesday. The Previous Occupant managed 79% of the Republican primary vote against an opponent who dropped out two months ago. I remind you that I Know Nothing About Politics before saying this, but it’s amazing how the polls say one thing and literally every other thing about this election says another.
  • Meanwhile, I was assuming my choice for Senate would lose because Indiana would choose the white guy, and they didn’t! Not only did Valerie McCray win, she won solidly, getting about 2/3 of the vote.
  • The sex pest won his primary too, unfortunately. I am probably just going to leave State Senate blank in November. Surprisingly, there is no Republican candidate, but there is a Libertarian running, and not only is he a Libertarian, he’s an engineer, which means he’s a jackass. It is possible to be either and not be a jackass but it is not possible to be both.
  • Today was a better day at school, not least because all of my knuckleheads from yesterday were excluded from class today. Today was the Math NWEA test, too, and for all indications it looks like it … went well? Possibly quite well? I won’t know for sure until tomorrow morning because it takes 24 hours for results to be fully available to teachers but damn near every kid I talked to showed growth.
  • Meanwhile, I’m definitely taking the high school Mathematics Praxis test this summer. My boss hinted that we might have enough 8th graders taking Geometry next year to be able to make a class section out of it, and I will fight anyone who tries to take that class away from me. That means I need to get licensed to teach it, though, so there’s a test to pass and some paperwork to get done. I can take the damn thing from my house, though, which is spectacularly good news.
  • I have chosen violence, and will be wearing a shirt that just says KENDRICK to work tomorrow. I’m expecting fireworks. It’ll be fun.
  • The final meeting of my little club of gay weirdos at school was today. We had a pizza party. I thought I had ordered far too much food. They each turned out to be a million locusts wearing skin suits, and everything I ordered was gone in seconds. I’m really going to miss these kids.
  • We had a fight in the hallway toward the end of the day, and I raised my voice to such a level clearing the hallway that I was hoarse for all of fifth and sixth hour. I’m hoping I can talk tomorrow.

Okay. That sounds good. I’m gonna go read now.
