After the last dance. Starting over. Year 9. Maroon.

Codes

Although students will walk back into my class on Tuesday, we won’t actually start the second semester “for real” until Wednesday.1 This is because three years ago, I started the practice of putting my B-day classes in front of my A-day classes for the entire second semester in AP Stat.2 The following is some background as to why I started doing this.


Each year at the start of the first major exam3 in AP Statistics, I put a brief “honor statement” at the top of the first page for students to sign.4
Just below is a shot of said honor statement:

Here’s the crucial text (in case you’re on a small screen):

HONOR STATEMENT: I understand that Mr. Youn expects that I will never discuss (nor have I discussed) the contents of any quiz or test with anybody else until we review it together as a class. This gives all of my classmates a fair chance at taking this test. I will respect my classmates by following these expectations at all times.

Please sign if you agree: _______________

I’m not naïve — there is no way to completely eliminate cheating.5 However, there are, quite honestly, a large number of students who don’t even realize that the behavior described in this paragraph is considered an act of scholastic dishonesty. The purpose of this exercise is merely to communicate our expectations to them. 6


Back when I was a senior in high school, our teachers would explain to us that we — meaning students — were competing with one another for spots in college, and thus, it ought to make sense for us to NOT want to discuss contents of an exam that we had just taken with friends of ours who were taking the same class in a later period that day.

But even in the “dark-age” absence of cellphones and social media,7 we had trouble keeping secrets. 8

These days, kids at my school are on an A/B block schedule, in which we have 8 total class periods, but only four 90-minute classes each day — so it takes a cycle of two days to get through all 8 classes. This, in theory, allows students to disseminate contents of, oh say, that day’s evil exam in AP Stat in between days.9 Oh, and not to mention, kids these days have incredibly sharp camera phones, and social media, and messaging apps galore.10

In theory, this gives a perpetual advantage to the kids who have classes on “B” days, as their classes — and thus, exams — are systematically a day later than for students who have the same classes on “A” days. 11

And this is one of the main reasons that I started teaching my classes B-day first for the entire second semester — it gives the B-day students a chance to be at the front of the line, and to make it through a semester sans the luxury of hearing about the next day’s class from their A-day friends.12


But the much bigger reason I choose to start with my B-day classes every January?

The following is a charming16 xkcd that touches on the universe of pain in which we’ll be living for much the duration of the second semester: Inference.17

xkcd #882: "Significant"
xkcd #882: “Significant”
  1. Tuesday will end up being some sort of review and/or data collection activity. Nothing that is overly “processor-intensive”. []
  2. I have also done this in Pre-AP Algebra II a couple of times, but more for reasons related to bad-weather days or other disruptions in the calendar. []
  3. Incidentally, the first major exam of the year has been falling on — or very close to — September 11 []
  4. and hopefully, read []
  5. A law-school friend of mine once pointed me to a study that indicates that institutions of higher education that make students aware of an honor code actually have higher incidences of scholastic dishonesty than schools that don’t… but I have to think that has more to do with the competitiveness of the students that attend such institutions, rather than the presence of an honor code itself. []
  6. Oh, it also provides excellent fodder for the “sensitive questions” activity that I pull on them much later in the year, after the last major class exam. []
  7. And I don’t even mean SMARTphones. Cellular phones didn’t become ubiquitous among consumers until I was midway through college. Like I said. Dark ages. []
  8. This perhaps begs the question of which code teenagers respect more: the code of honor or the code of friends? I’m sure there’s a lesson on game theory in there somewhere… []
  9. not to mention in between class periods []
  10. Oh, how I cannot wait for communicating during exams via smart watch starts to become a thing… </sarcasm> []
  11. When you teach the kids at the higher ranks, this kind of stuff is not insignificant. Last year — Season 7 — I taught the entire senior class top 10… that was an interesting dynamic at times. []
  12. Not that this approach solves everything — with this regard, kids with class later in the day will always have an advantage over kids who are in the morning periods, etc. But it does mix things up a little, at least. []
  13. And oh boy, after a grueling stretch run to close the first semester, this Winter Break was closer to hibernation than any Winter Break I’ve had since college… []
  14. and in the second semester of any math class, the first lesson is never light-weight []
  15. That’s the code I prefer to go by: the code of mental self-preservation. []
  16. well, *I* think it’s charming []
  17. After “Inception” and “Interstellar”, I’d like to a Christopher Nolan flick about “Inference”. Like his other stuff, you’d have to be genius to understand it… []

“y” equals a million over three

N.Y. Times: ‘The Interview’ Brings in $15 Million on Web

The following excerpt elicited a sharp “sigh” and a “c’mon man” from yours truly:

Sony did not say how much of that total represented $6 digital rentals versus $15 sales. The studio said there were about two million transactions over all.

As a former Algebra II teacher1 I couldn’t help but groan.

But it’s not because I think that we’re getting stupider and stupider.2

It’s because the type of stuff — such as this, be it on rare occasion3 — that might actually be useful in real life is the type of stuff that we don’t bother teaching enough of in the classroom. 4

In any case:
Let “x” represent number of online rentals, and “y” represent number of online sales.

x + y = 2 million
6x + 15y = 15 million

(I know a handful of Algebra teachers that’ll be available for before or after-school tutorials next week if you need help finishing the rest…)

  1. I have fond memories of teaching Algebra II. []
  2. Which is not to say that I don’t, but that’s another story for another day… []
  3. A “hacking” incident which “forces” Sony to test the waters of releasing a major motion picture online is rare by my book. []
  4. I know exactly in which unit we would teach how to set up this very type of word problem in Pre-AP Algebra II. I also know that we never taught it in on-level Algebra II, which is what I consider the real ill omen. There’s so much I could go on about the “standards” and about how educational “experts” are convinced that constantly redefining said “standards” is some magical shortcut to improving results — here’s a hint: there are no shortcuts — are moving us in all of the wrong directions… but… that’s another story for another day.

Movies I saw in 2014

I like going out to the movies.1 Lately it has become my panacea of choice after a long week of teaching2.

Just for fun, I recently went through my email confirmations and made a list of the movies I’d seen this past year. (You’ll think I’m either really awesome or really crazy. Either way, I definitely need more of a life.)

Here it is, in roughly reverse chronological order:

  1. Especially in the city of Alamo Drafthouse []
  2. and grading papers and other stuff []
  3. These are the ones I watched in theaters that came out during 2014 — with the possible exception of “Begin Again” which has an official release date of 2013. I also saw the “South Park” movie and “Stand By Me” for the first time this past year. []
  4. Curious about my favorites? I’ll only say that “Guardians of the Galaxy”, “The Drop”, and “Boyhood” are in my top 5. “Imitation Game” might be, once I have more time to process it. I still haven’t decided how I feel about “Interstellar”. “John Wick” and “The Equalizer” were surprisingly good. The “Hobbit” finale isn’t in my top 10. []

“Show me your ears.”

Because some of this stuff, you could not make up if you tried.

Context: It is week #13.1 We have two days to go until our first-ever week-long Thanksgiving Break.2

A brief conversation from class this morning as we were about to start our lesson:

Student #1: If we win state,3 will you get a mohawk?4
Me: Uh… no. Pretty sure that wouldn’t look good on me.
Student #2: [Gasp!] You should tie it back in ponytail!5
Me: [Rolls eyes in silence and trying not to smile so as to encourage them…]
Student #3: ooOOooo! You could do a ponytail that goes straight up!!6 And then get your ears pierced!!!
Me: Uh…
Student #4 (who is a football player): Show me your ears.7
Me: WHAT?!?
Student #4: We’ve never actually seen your ears before.8 C’mon, just whip ’em out!9


Somehow I managed a silky-smooth transition from that into a lesson about using the Normal model with combinations of random variables. Don’t ask me how. It just happened.

Turkey week break, please come hither.

  1. Frighteningly, we are about at the halfway mark of the course in AP Stat. It’s darn near impossible for me to believe that even as I type it now. We’re halfway there…. []
  2. So everyone is getting kinda delirious. []
  3. our football team is in the playoffs []
  4. On a side-note, it has apparently become a popular pastime as of late for students to bugger me about getting my hair cut. []
  5. This is another equally foolish notion that seems to be gaining a cult-like following. []
  6. This was from a normally quiet kid who sits in front and doesn’t usually say much, to boot. []
  7. Yes, that sounded as awkward in person as it reads on screen. []
  8. Which is a total lie. My hair was short enough to see my ears as recently as September… []
  9. Yes, again… just as awk-sounding in person as in print. []

What. a. week.

At one point this week, I had one of those rare “there is no more ‘nice’ left in me” moments. It was one of those weeks.

This is pretty much how I felt by the end of the week...
Courtesy of 7th period. This is pretty much how I felt by the end of the week…

Today is… a number of things.

Today is the thirteen years to the day that Magic Johnson announced his retirement from the Lakers due to HIV.1 I still remember that Thursday afternoon like it was yesterday.

Today is also the official opening of Christopher Nolan’s “Interstellar”.2

And today was finally the end of the second six weeks3 which means that Season 8 is a third of the way through.4 Time keeps flapping its wings faster and faster, indeed.

  1. which the Lakers unbelievably trotted as “a severe case of the flu” for a couple of weeks []
  2. Can’t wait to see that thing in 70mm IMAX! []
  3. which was technically only 5 weeks but felt like fifteen… still not as bad as the 3rd, which is only 4 but will feel like forty. []
  4. Yikes!!! []

Guess My Age, redux

Some of the funniest moments of the year happen when we do “Guess My Age”.

For contrast, when we got to Leonardo DiCaprio…

Last year:1

Girl: Wait, he’s HOW old?!?

This year:2

Girl: I don’t care. If he’s 62, I’m 61.

Also, I decided to keep former Texas coach Mack Brown on the list. When I told them:

I considered kicking him off, but I didn’t have the heart…

…a young man in class today retorted with:

“UT did.”3
