ETC: Anime North 2013: II


Continuing here off my previous post, rambling about Anime North 2013. Notably my seventeenth Anime North, of seventeen, and I still have all the badges. More on that later.

4) A CERTAIN HAPHAZARDNESS


At 4pm on Saturday, went to check out the Steins;Gate video, because time travel. But they were having video problems. After about 20 minutes, I went to "A Certain Magical Index", another series I've been meaning to check out. My wife came to find me 5 minutes later, as they'd fixed the video, so I got one ep of Steins;Gate and then an ep of "Magical Index" which was still going afterwards.

At that point I popped off to the Dealer's Room for an hour, to give it a scan. Saw a couple cosplaying Nanoha and Fate, so OMG, totally worth the trip for that alone. They had rather intricate Raising Heart and Bardiche. In fact, I only really browsed the merchandise room for Nanoha (with the 2nd movie having come out last summer), and got a small Chrono for my troubles.

Returned for "A Certain Scientific Railgun", but the room was packed. That series has been on my mind ever since my episode with Hyper, as one I keep wanting to watch beyond episode 1, yet never managing it. So I switched hotels to the manga library, and checked out the "Railgun" manga to read. (Ha!) Met back up with my wife at 7:30pm for an actual meal of some sort.

5) HIGHLIGHTING


Went to check out the Filk/Geek concert after dinner; by this time it was after 9pm, so I'd missed half of it. Though since I might not have even gone if it weren't for the earlier panel, I think I come out ahead. Was there for Kari's entire ukulele set, including the song "Being Watson" which was my favourite. I then bought a Debs & Errol CD (signed!), and probably should have considered more, but still wasn't sure what I was getting into.

Concert was followed by "Songwriting Contest", which was mostly a sharing of geek/filk/neat music and such. Listened to a couple. Then I sang. One of my math songs.

Yes, really, that happened.

I'd been tempted by the openness of it, but less sure about my limited use of parody. Ultimately, when there was a lull, I figured heck with it. One guy even found a karaoke version of the music to play as a background - it was "Mean" by Taylor Swift, except the version with median and mode. (Still in my memory, as the last one I wrote.)

The bit that floored me though was at the very end... when Debs said she'd be inclined to hear another math song. I didn't actually have any other lyrics on hand though, so declined. But this was the first time I had anyone outside my profession or circle of friends say "hey, that was so neat I want more!". So... maybe there's something to this.

I need to look into more of this "filk".

Anyway, at 11pm things gravitated to an Open Filk, and I bowed out. Partly because I did still want to see some of the Anime Music Videos from the MVC. There were a number of fun videos, with the last one actually kind of thought provoking. It got at the implications of fanservicing characters, and how that sort of thing would have implications in the real world. Hm.

From there, a quick spin around the video rooms again just to see what was playing, whereby I ran into Karl Z for a brief chat. By now it's after 1am, so back to hotel.


BOW TO THE CHIBI-TANGENT!
BY HELEN TRANCY
SUNDAY

Sunday started with me posting my web serial, then meeting with my parents for breakfast. Didn't get back to the Convention at the TCC until about 10:30, at which point I went around to pick up my art commissions from the previous day. They are all AMAZING, and I may soon be using them on serial publishing days if I don't get the chance to actually refill my buffer. Here's one to tide you through.


6) ANIME OR MAY NOT


Just after 11am, went to see "Time Jam", which my wife had heard about at the "French Connection" the previous day. Basically, a guy from 2417 picks up a girl from France in 912, and they end up in a bizarre alternate future. Reasonably entertaining, and curiously based "on the comic books", so I'm wondering what those were now. It was a France-Japan collaboration.

I then swung by the Con Office, because a person at TCC Con Aid had suggested that I'd be of interest to Eileen, who does memorabilia, given how I had all the badges from previous Anime Norths. She was indeed, particularly in 1999, which they didn't have a graphic for. So they scanned a couple badges in, and gave me one of the more rare pins (of 2004?) for my trouble (though it was really no trouble).

I then went to "Horrible Anime Music", but the panel had already filled and closed, so I wandered video rooms instead. Bit of "Doki Doki Precure" and "X Men", then wandered back to the Manga Library and AMV Room. Oh, yeah, there's an "X Men" anime featuring some girl named Hisako alongside the regulars. Okay then.

Planned to go to the panel "Your Art Doesn't Suck" at 3pm, and got there about five minutes early. After about ten minutes of standing in line, and more people queueing up, and wondering why the previous one was going over... a volunteer checked, and said the panel had started early, and was already full. Well THAT would be useful information to put on a door or something!!

So I went to check out "A Certain Scientific Railgun" playing in the dub room, and got to see the second episode, which I guess is something. From there to the 404s performance. They were celebrating 10 years, and took a picture with the audience. Watched about half the performance (World's Worst Gundam Pilot... guy starts dancing like Psy, heh), then took a quick spin back to the Dealer's Room, as I figured I'd buy a couple other items if they were still there at the end.

There were some Nanoha figurines left, and the person was nice enough to exchange when I got two of the same. (They were in mystery boxes.) So I have a Yuuno, Arf, and Fate to go with Chrono. Also "Weirs Schwarz" had some Nanoha 2nd Movie card packs; this seems intelligent, as I don't know the game, but bought some cards.

Ended up leaving at 5pm, even as I realized that was really stupid as EVERYONE was leaving then. But someone said there was a detour exit out the back of the TCC, so I was on the road by 5:30pm and back home for about 11pm. Yay!

FINAL THOUGHTS


Anime North has become more of a tradition than anything else for me. There's certain people I only tend to run into there, and it's one of the few remaining ways I keep in the anime loop. But this year was a bit more key for two reasons.

First, the art commissions. Given I'll be missing ConBravo for TMC13 (see previous post there), this was the best opportunity for them, and also marks the first year I think I spent more on art than in the Dealer's Room. I like supporting art, to the tune of I forget how much the commissions actually were.

Second, the filk. I don't know why I've been oblivious to it until now, but I've started following Debs & Errol on Twitter, and will be trying to keep an eye out for more of this aspect of "geek culture". If you know of any extra tips for me, let me know!

Not sure if I'll be able to go next year. Time will tell. In the meantime though, I now have a tiny Fate to watch over my desk at work.

ETC: Anime North 2013: I


There is some writing stuff in this post, but it's mostly a recap of Anime North 2013. Why? For the purposes of my memory, and to see if you spot anything else of use. (Hopefully you'll tell me if so...?)

FRIDAY

Friday doesn't happen for me any more. From experience, the earliest I can get to Toronto (after a day of teaching) is 8:30pm. While registration is still open then, the last few years they've started closing the line at 8pm. So since there's no chance, I don't rush. Got into town about 11pm, went to bed.

SATURDAY

Woke up before 7am, breakfast, got to TCC registration line just after 8am. Marked papers for an hour until registration opened. Moved through line fairly quickly, from there to the AMV room, no point lining up again in the line longer than ours.

1) DRAWINGS


Para Bola. STILL AWESOME.
STILL BY MICHELLE SIMPSON
Returned to TCC after 11am. Not for the dealers room - I wanted to commission art of my mathematical characters. (Still really like the Para from Con Bravo last year, pictured on the right.) So I actually looked though ALL artist booths in the alley for the first time since... well, since it just got far too big for me.

Many who listed commissions said they needed "a reference", so immediately I'm thinking wow, you need to phone one of my friends? To make sure I'm good for the money? Then I realized they meant a drawing reference. Which is fine, I'd brought some of my sketches.

Over an hour later, I had 5 artists who would individually sketch Linear (coptic), Tangent (chibi), Para (line art), Root (ditto) and the Trig Twins. Some borrowed my sketch, others just took a photo and let me keep it. That seemed smart.

2) WRITING


At 1pm was the panel "Fic Fic Boom", by the usual suspects: Chaos, Steve Savage, Nightbreak, and Sean Gaffney.


This tends to be a riff on bad fanfiction, but Steve basically started by saying Amazon was going to be publishing fanfiction, so given "50 Shades of D-Grey Man" would soon be legit, "There's nothing to joke about anymore". (He goes into more details of the Amazon deal in this post at FanToPro.)

A few takeaways:
-The recent shift is away from Reality Shows and towards Fairy Tales (as no rights needed).
-Everything's going anthropomorphic (ha, I have a leg up there) along with fanfiction of real people (like the panelists).
-People need to stop using Dr. Who as the little black dress of fandom, even if it does go with everything.
-"Pandering" to fans in writing usually results in problematic plots.
-And finally, someone needs to write the existential book "Why is Waldo?"

After that was a panel on "Getting Published". I don't have specific aspirations, but info is good. Plus Derwin Mak was on the panel, along with Karen Dales. A few takeaways:
-You don't need an agent for short stories. George RR Martin ("Game of Thrones" guy) got his start with short stories.
-"Story" definitions can vary; short story word counts (5,000-9,000) versus novels (40,000-120,000) are North American, UK novel limit is higher.
-There's a difference between self publishing and vanity publishing.
-Harlequin stories are extremely formulaic because the publisher made the rules (eg. "By page 30, your protagonist will have...")
-"Finding a job is easier than finding a publisher."

3) SONGWRITING


At 3pm, I was torn between "Create that Anime", an AN staple with Steve Savage and "Songwriting/Parody Songs", given my recent inclinations. I went with the latter, and WOW am I glad I did. I got introduced to the world of "filk", with a panel including Leslie Hudson, Devon, Kari, Errol and Debs. Those last have a daily comic, go check that out.

More takeaways:
-February is Album Writing Month (FAWM). 14 songs in 28 days. There's a month for everything.
-Stay creative. If you're stuck on a rhyme, put in filler lyrics, keep going, fix it later. If a lame idea keeps asserting itself, get it out on paper so you can move on to fresh territory.
-More ideas: Put a song to another tune. Vary things up, grab a random chord from a jazz song, or a musical; Disney songs and Christmas songs have some crazy chord progressions.
-Rap lyrics is all about cadence, and word stress. (I think this is why I find that so hard to parody... and write...)
-As soon as you've recorded your song, that is a standing copyright.

They also mentioned the "Filk/Geek Music Concert" later that evening. In retrospect, the past 5 hours were probably the best ones of the whole weekend. I actually wouldn't get into any other panels, because there were lineups and cutoffs based on room occupancies, which I failed to account for. On Saturday morning I saw a sign like the one I'm holding here (memories of ConBravo), but not after, and it all seemed to be rather haphazard.
NO LINE DANCING ALLOWED

The highlight is yet to come though. I'll continue in a subsequent post.

Still, it's occurred to me to simply present the data, and then see if anyone else has thoughts. That way when I finally analyze (who knows when), I can actually address particular points people would like to hear about. Assuming there are any.

TCH: Two Teachers Per Class


The more I think about it, the more it makes sense. Have two teachers for one class of students. And I'm not talking about one teacher (or educational assistant) who deals with those two "difficult" students in the corner, while the other teaches, I'm talking about having two teachers. Hear me out.

ORIGIN OF THE IDEA


I've been tweeting hours worked for the last month or so. I plan to have a roundup post on that at some point, but one thing I'm starting to realize is that the job is potentially doable in a regular 8 hour day. Assuming you don't do any marking, or extra curricular activities. (Effectively filing off the worst and best aspects of the job.) If you must do those things, well, sacrifice sleep.


Today in particular, as I marked, I wished I had a day just to do only marking. (Which is what the weekend is for. Yet I blog. Yeah, I'm stupid like that.) I also listened to the latest "Infinite Tangents" podcast, where there was mention of "laying out a class" based on overall curriculum expectations - hopefully collaboratively. Thus with help. Okay, so what if I had a FEW days to mark student work, because we'd arranged that someone ELSE was currently teaching the next unit? I'm not saying I'm hiding out, I'm still helping the classroom during the day, but when I'm not there I'm MARKING rather than PREPPING.

This means I can focus more on the problems with the last unit, even having time to make changes so it's better for next time, rather than trying to figure out what I have to be teaching tomorrow. Our next unit, the two teachers switch it up, so that it's not one person tasked with all the marking all the time. Notice I also flagged this post as "teaching" not "math", because I think it's workable in other subject areas too.

I hear your objections. But bear with me as I work through this.

COMPARISON


Advantages to Two Teachers Per Class:
1) Teachers don't get to observe enough teaching. Boom. Fixed.
2) We emphasize group work, yet we teach in solitary. Why?
3) It's a chance to share (equitably) what always feels like an impossible workload.
4) A second set of eyes in the class can more easily pick up on problems students are having. Also allows for constructive feedback to colleagues.
5) Pretty sure this would reduce teacher burnout and increase retention rates.
6) This might even allow for better flipped classrooms, as it generates time for teachers to create flipped content. Or just any content.
7) Creates jobs, which is good for the politicians and prospective teachers out there. Alternatively, may mean the bureaucracy can increase class sizes, but as long as they're not doubling, we'd be looking at less than what we have now.

Disadvantages to Two Teachers Per Class:
1) Seems to require units. I'll deal with that below.
2) Personality conflicts. Two teachers with different styles may not mesh well, or issues may erupt if students seem to "prefer" one teacher to the other.
3) Continuity. Students may have difficulty handling a different teacher for different topics, and teachers may have difficulty picking up where someone else left off.
4) Coordination. Two teachers now have to assign one mark per student.

IT'S ALL ABOUT PROS AND CONS

ABOUT DISADVANTAGES


It doesn't require units. It might make more sense to have units, where Teacher A takes 1, 3 and 5 while Teacher B instructs 2, 4 and 6, but not necessarily. Picture a classroom where all the topics are laid out within the first two weeks. Teacher A can then do an activity on trig (perhaps even based on current events), have an evaluation of some sort at the end, and while they're correcting that, Teacher B does a few lectures about solving equations. Then Teacher A is on again, and they could do something on quadratics - or, y'know, even FOLLOW UP on their activity from two weeks ago. (Seeing it again before the final exam? Madness!)


I can't immediately see why this can't apply to other subjects too. Teacher A instructs on World War I, Teacher B on World War II. Teacher A does chemistry, Teacher B jumps in with some physics. Teacher A does the poetry unit, Teacher B gets ye olde Shakespeare. Teacher A does perspective drawing then Teacher B moves into watercolours. I suppose you could argue we may get too specialized, but is that a bad thing?

Personality conflicts is a bit harder to reconcile. This whole idea would need to be a collaborative exercise, not a competition, yet there's always people out there who have a personality type that leans to the latter, or who might take things too personally. (I may even be one of them.) Students would not help matters, tending to be judgmental, or simply wanting to see what happens when you pit two teachers against each other.

But on the other hand, there are some really good teachers in my department doing some great things with group work and... that isn't me.

I'm an introvert, who is bad at judging personalities and gathering anecdotal evidence. So I don't do a lot of it. But if I was paired with someone who WAS good at it, not only would the students benefit, I might get BETTER at it. Meanwhile, that teacher... would get to see me sing about Trigonometry. Um. So they might feel they're getting a raw deal, but they could be paired with someone else next semester. My point is, play to individual strengths and evolve as a teacher, rather than get stuck in a rut.

As far as continuity goes, most times students get different teachers from year to year anyway, so it shouldn't be all that confusing. And as to continuity with teachers - again, it's not that you vanish for a week, you're IN THE CLASS, observing what is being taught, it's just you can deal with marking and self improvement rather than all the prep work. Because of that, I can't think there would be huge disputes about mark assignment either.

Heck, in terms of implementation, this could even translate to just having a couple "floating" guys in the department. They teach collaboratively with Teacher A for one term, then Teacher B during the next term. You know, kind of like student teaching, except with pay. So this might be particularly beneficial to young teachers, as they build confidence and find their place.

THAT SAID


The major disadvantage, of course, is that this has to be sold to the public. I say "public" not "politicians", for two reasons:
1) Despite the politician's apparent penchant for doing whatever, then selling it as "the right thing", surely there are some times they have to bend to the will of the public. Like, election years.
2) The public thinks teachers "have it easy", hahahaha, kill me now. They're the ones to convince of the benefits of such a system, and why more money would be needed for education to implement it. (Maybe if we take some of that tech money, eh? Then again, my ten year old computer says new tech would be helpful.)


Well, I'm not a salesman. Nor am I sure how I'd advocate for this. (Nor am I even positive it's a good idea.) That said, is this NOT what they do at the post-secondary level?? Hiring teaching assistants to mark papers and answer questions, so that professors can focus on research? My system improves on that, as I'm not passing the drudge work on to someone else, but making it more equitable, distributing the workload fairly between two professionals. Doesn't this make sense?

I feel like it makes sense. In the comments, someone please tell me why we're not doing this.

MAT: OAME 2013 Day 3 - Laments


Thursday was OAME Day 1. Friday was OAME Day 2. This post is about the half day Saturday, now that I've made it back home. At least one person has told me (in person) they liked reading about a session they didn't get to, so hey, here we go again.


BOB POINTS OUT HE'S LEFT HANDED, RIGHT BRAINED

1) Keynote: Bob McDonald

Topic: Vacations in Space

This would indeed be the host of CBC radio's "Quirks and Quarks". He spoke of how they measured the Earth in 220 BC ("stadia" used to be a unit of measure), the shuttle that allows one to experience weightlessness (G-Force 1), and moving out into the universe. Notably how people will pay large sums of money to be rocketed up there. Solar sails may be big in future too (ooh shiny!) and I liked the idea of a "weigh" station in orbit that has different gravity in different areas, to adjust to the gravity of your destination.

Takeaways:
-"Our ignorance is greater than our knowledge." We still don't know where a large part of the universe's mass is, nor how to turn off gravity. If you drop something, inertia says it should STAY there, in the air... unless you're close to a large mass...
-"We are the centre of our own personal universe." We see things from our present frame of reference, which can get interesting if someone jumps into a swimming pool that's actually a rotating ring keeping the water in place. Or when you're not sure where a student is going when tackling a problem.

2) Session

Topic: Free Falling - Letting Go of Textbooks, Worksheets and Units

Bruce McLaurin talks about risk, and working without a net. Not necessarily just a flipped class (though it came up) but a class where you introduce all topics at the beginning, then can cycle through the curriculum, without chapters, without units. One day, ask "what's the difference between (x+1)^2 and x^2+2x+1"? Another day, incorporate actual news items into the classroom, like sinkholes, the russian meteorite, or Felix Baumgartner's free fall from space.

Bruce posed six questions over the course of the talk:
1. Do you ever allow students to explore problems that you don't know the answer to? (Is it a problem if you already have the answer?)
2. What's wrong with textbooks? (Participant answers included generic, structured, language used, contrived...)
3. What are the advantages of working without units?
4. What's with the flipped classroom? (Setting aside watching videos, it shifts the responsibility. Students aren't used to LEARNING, they're used to BEING TAUGHT.)
5. What is the problem with worksheets?
6. Does "free falling" take a certain personality type, or does it take the confidence that comes with experience? (Both?)


OR YOU'D BE ON IT, GOING NOWHERE

The article 'Right now, we build minds the same way we build cars' came up, and the fact that it can be scary for us to give control to the students... in part because many come up with lame questions on their own! But they also see stuff we don't. "The Mathematician's Lament" was mentioned. Also, a possible summative task: "Design an experiment to demonstrate at least 2 functions of the course (3M) using a string, a weight, and a monkey." Consider visiting Bruce's Blog, he started it last month.

Takeaways:
-"When standing on the brink, don't look down. Look forwards, and have faith."
-"If they don't hear it in your classroom, when are they going to hear it?"


3) Session

Topic: Mathematical Ethics

Douglas Henrich also mentioned "The Mathematician's Lament" (it seems to come up every year, I should get a copy...). Though key to the session was how mathematics also has a social dimension. There were two main aspects that I took away with me:


ALSO, ONE POUND
IS NOT 500 GRAMS!
1. Ethics can be seen as Consistency. This is what we strive for (in notation, etc), yet we're not great at it. For instance, when you draw two triangles with equal sides, we say they are "congruent". Why not "equal"? Well, is there anything physical that is truly identical the way an equation is? Is our use of the word "equal" consistent? Alternatively, in Grade 9, "zero" isn't "nothing", particularly with regards to slope, or zero pair algebra tiles. So if "zero" and "nothing" were equated before, that's not consistent. There are social inconsistencies in math... times when we "cheat", and/or teach abridged versions, which might encourage students to do the same, or tune us out.

2. Ethics can (should?) be a component of a mathematical answer. The example given was: "XYZ Corp are making a product in demand, but contaminants are adversely affecting a population of dove-tailed turtles. The higher the turtle mortality percentage, the less items are bought, and the lower the profits. Given the following equation, find the optimal dove tail turtle mortality rate that will maximize revenue."

There's an element of social responsibility being lost to the hard numbers. Follow up question: "As the mathematical consultant to XYZ Corp., are there any ethical considerations you would bring to your client's attention?" For instance, the problem of cumulative effects, or multibillion dollar lawsuits down the road, that would offset these short term profits. To me, this seems especially pertinent of late, given all the recent news about labour conditions in other countries.

Douglas did point out that such questions are not simple to come up with. He also runs a senior computer science course where the summative is to hack into a particular computer on the network (subject to some constraints, like no physical damage). There, the learning comes from the experience, not success.

Takeaways:
-"Can we do this in math? I don't know, which is partly why I do these talks." (Linking back to the prior session - asking questions that we don't know the answers to.)
-"Do we want students to use math to READ the world, or to TRANSFORM the world?" (Effectively an individual context versus a social one.)

Miscellaneous

At the end, I went back to the larger 'featured speaker' room; I didn't sign in for any today partly because my Thursday was ALL features, but that doesn't mean I wasn't curious. A colleague coming out said a statistic from the "Dyscalculia" session is that for every 14 studies on Dyslexia, there's only one on Dyscalculia. Huh. Also ran into Kate Mackrell and Jimmy Pai again before I left.

So there you have it. I hope you were able to find something useful within my posts of the last few days.

Friday 3 May 2013

MIX: OAME 2013 Day 2 - Write Stuff


MAT: Mathematics + WRI: Writing

My first mix tag since I started the new blogging system. (How's that working out for you, readers?) It's pretty much due to Ron Lancaster. We'll get there. If you missed it, yesterday was Day 1 of OAME 2013. This is day 2.

WRITING FEATURES MOSTLY IN PARTS 2 & 4

1) Keynote: Annie Kidder

Topic: Defining and Measuring Educational Success in 21st Century

Annie (also on Twitter) is from the "People For Education" group, who are meant to provide an objective viewpoint on public education, with supporting evidence. Basically, moving away from opinion pieces on such a polarizing issue, going for statistics. Such as: only 10% of students take ONLY applied math; 62% have three or more applied math courses.

(Aside: For those not familiar with Ontario's education system... there are effectively two streams in Grade 9, the 'applied' and the 'academic'. If you enter at the applied level, you need two Grade 11 math to lead to University Calculus, as opposed to just one; both can lead to College.)

There is, it seems, a strong correlation between average family income for a school, and the percentage of students taking applied courses. That is, lower income area means higher percentage of "applied". So just because you have rich parents, you're better at math? There is also a correlation between family income and being a member of a band or a choir. See NY Times article No Rich Child Left Behind.

We're blaming failing schools for trends that are more the result of the behaviour of the rich.

Takeaways:
-When you make a narrow definition, it defines where you focus your efforts. We need more USEFUL measures, not more JUDGING measures.
-How do we define SUCCESS? Then how do we MEASURE it, because it's not enough now to say "just trust us", society needs to see numbers. Related, why do we equate PROSPERITY with "Money! Jobs! Economy!" instead of "Equity! Joy! Citizenship!".
-There are problems with the system. (Chief among them, why do people say, "I know all about education, because I went to school!" more so than "I know all about surgery, because I had an operation!")


2) Session

Topic: Powers of 2 and Exponents

My first Ron Lancaster session begins: Some numbers can be written as the sum of consecutive numbers. For instance, 5=2+3; 6=1+2+3; 7=3+4. These are known as polite numbers. What numbers do NOT have this property?

All the powers of 2. And only the powers of 2. And, I'm hooked.

We need to balance curriculum with the curiosity of the subject. In particular, just because something doesn't have an immediate "real life application" doesn't mean it won't DECADES LATER. For a simple example, RSA and prime numbers.

Writers! Have you tried Constricted Writing?

THERE'S YOUR WORD OF THE DAY

How many different combinations of vowels are there? For instance, 'a', 'e', 'i', 'o', 'u', 'ae', 'ai', 'ao'... and so on to 'aeiou'. (That's the math bit.) Now, can you produce a work using ONLY that type of vowel, or vowel combination? Canadian Poet, JonArno Lawson, did just that with "The Voweller's Bestiary". From aardvark to guineafowl. For instance, in the poem called 'Raccoons', he used only a's and o's.

Wow, I can't even. That's a lovely little challenge. Don't like that? How about every other sentence you write excludes a particular vowel. Or write a sentence where the word lengths constantly increase by one letter. (To a point and then decrease back, perhaps?) Will this necessarily be something you'll publish? No. Will it improve your skills and your vocabulary? Very possibly.

Back to the maths (more writing later!), here's an interesting pattern if you have a set of numbered cards. Starting with 1, you deal, then skip, then deal, then skip... then go back and deal the skipped cards the same way... until you're only left with one card. You might be fooled into thinking the pattern between total initial cards and value you end with is linear. It's not.

By the way, any readers from New York out there? Check out Math Trails.

Takeaways:
-The best stuff sneaks up on you. Perhaps don't say 'prove this is always true', say, 'how might you convince someone that you aren't missing any case where this is false?'
-A reason teachers can improve over time is that students (and educators) can show new approaches, which you can then use again in later years.


3) Session

Topic: Mathematics in Gaming and Architecture

Speaker (Jelena) who moved from high school to college teaching remarks that students don't know proportions, among other things. A student once said to her "I thought architecture was just about drawing" - without thought to, say, building code violations. How can we strengthen connections?

Interesting personal note: when she said "separate into small groups for open discussion", I inwardly cringed. I think this is part of why I don't do a lot of group work, it's really not my milieu. Of course, in the end it was fine. The few tasks provided to us as starting points also reminded me of others out there where students have to decide on what's important.

Notably, in a particular game, two line equations are given for a ball and a player. Now, is the slope merely the TRAJECTORY, or is the the RATE OF CHANGE (the speed) of the player? (If they run faster, does their slope increase?) Because, yeah. Definition shift between Grades? Also, leaving out units can be a key point of inquiry. Even in the United States where they're already in imperial (BECAUSE THEY'RE ANNOYING), they'll still need metric if they're going to buy anything from IKEA. (Ha!)

A possible summative task for Grade 10 Academic? You have two circles, moving on lines, getting closer together. How do you know when they touch/intersect? (Boom, circles, distance formula, triangles from start point to intersection... though I don't teach Grade 10, so maybe not?)

Takeaways:
-"You can make things as complicated or simple as you want." A task is what you make of it. Measurements based on student SELF is also a way to lead to different answers, all correct.
-A continuum is nice; perhaps a Grade 10 task can be redone in Calculus, by adding a third dimension, or speed/related rates. ("This looks familiar.")


4) Featured Speaker: Ron Lancaster

Topic: Using Fiction and Film to Teach Mathematics

The main topic was "The Housekeeper and The Professor", a book written by Yoko Ogawa and translated into English from the Japanese. In brief, a housekeeper goes to work for a math professor, who has suffered a brain injury and only has an 80 minute memory. She has a ten year old son that the Professor nicknames Root, due to his hairdo.

And, I'm hooked again.

Yoko Ogawa has actually won awards in Japan. The book bridges subject areas and a colleague in Ottawa has read it to her Grade 7 class. It starts off right away with the date February 20th. 220. A friendly number (with 284). A hallmark of the friendship that begins between the housekeeper and professor. Yes, english math themes. It goes on... did you know all even perfect numbers must end in 6 or 8?

Ron supplemented his talk with pictures and a brilliant offhand remark... incorporate a photography component into an assignment. Why should a teacher have to hunt down a picture of a parabolic bridge when it's so easy to snap a photo with your phone these days? Even actually TEST whether it's a parabola or just something close?

The sum of any two consecutive triangular numbers is a square number. Proofs without words. Could you prove something to a classmate using only pictures and gestures?

Writers! Hope you read that bit. Here's your other hook: There are stories behind every picture. Ron told us some as he was showing them, about where he took them, what led up to them, like 'the missing bell'. Reality is stranger than fiction, but the next time you look at a picture - write a story about it. Or if you're blocked in your writing, do a random search, and write something based on the 3rd image hit.

WHY DO YOU THINK I TOOK THIS PICTURE?
WHAT WAS HE SAYING JUST BEFORE THIS?

The real kicker: the book was adapted into a live action movie in 2006. The book takes place from the Housekeeper's perspective. The movie takes place as a HISTORICAL RECOLLECTION from the perspective of ROOT, who is now a high school math teacher. It's called "Hakase no Aishita Sushiki", or "The Professor and his Beloved Equation". OMFG.

I now have a copy of the movie. This is going to rival "Nanoha The Movie 2nd" for my attention once I have spare time again... though I'm a bit worried that I'd spoil the book by watching it first.

Takeaways:
-Why should it be so unusual for a math teacher to go to the school library to request a book? "Math on Trial" just recently came out; why aren't math educators more aware of fiction/non-fiction in their subject area?
-Followup to earlier: Don't say 'prove this identity is true', say, 'this is true... HOW ELSE could you write this?'
-Like the Professor, remember to thank students when they answer your questions; don't just charge on with the remainder of the problem.


5) OAME Meeting and Banquet

I like going to Meetings when given the chance, partly because I want to know how the process works. I don't often go to Banquets, but decided since I wasn't paying for the conference (as I presented), I'd go for it. Learned the attendance at OAME2013 was about 1800 people.

Meeting takeaways:
-For only the second time, we had a triumvirate of women heading OAME, as the president-elect, president, and past-president were all female.
-Just because you've always done something one way, doesn't mean it's the only way to do it.

AT THE BANQUET, BY CHANCE, I PARKED BY RON'S CAR

The banquet itself reinforced a couple of things: 1) My belief that every picture tells a story. (If you saw the license plate MAD4MATH, what would you think? Now, what if you knew it belonged to Madeleine?) 2) My belief in myself; someone said they were inspired by my talk, and were going to try to have some music in their math class. So, blushing.

Ron Lancaster also designed place mats with math puzzles on them, to work on while we waited to be called for the buffet. We were called by table, and there was a free drink in it for anyone who could identify the random sequence in which tables were called: 7, 3, 2, 4, 6, 8, 1, 9, 5.

No one got it. In retrospect, it recalls a conversation I had Wednesday night with Mike Campbell related to Data Management.

The answer: It was a random number sequence. The committee chair sat in the hall at some point during the conference, and asked passers-by to give him a random number from 1 to 9. (The first three numbers he got were ALL 7.) Numberphile actually did a video related to this.

Quick, think of a random number from 1 to 4!

You picked 3. Humans are very bad at random numbers.


Miscellaneous

Again, had lunch before the last featured speaker. Though also visited exhibitors before that. Apparently Brock University is starting up an online math contest for senior grades. I need to go back to check that out. Also, when I checked in with textbook distributors, they're moving texts to electronic versions... except, you know, Data Management. It's low priority, because the text is about 10 years old (from before the latest curriculum revision), and the course doesn't run with nearly the volume that calculus does.

You have no idea how backwards that seems to me. I was sitting with Tess Miller at the banquet, and she postulated that there wasn't the money in it, despite Data Management being of more use to, you know, everyone. (She also said that in PEI teachers won't go to any PD after the end of the school day. Different culture!) Also ran into Kate Mackrell, whom I know from QueensU and prior conferences, met Dan Allen through some tweets, and encountered Patti Walker, who knew ME through tweets, so, nice.

I WAS REALLY THERE! SEE?

Anyway. This took two hours to write and assemble. It's now after 1:30am. I should sleep, tomorrow I've got three more sessions, then a five hour drive back home.

Thursday 2 May 2013

MAT: OAME 2013 Day 1 - Key Notes


As I said recently, I want to record more Professional Development. That entry was meant to be a warm up for OAME 2013, the Ontario Association for Mathematics Education's Annual Conference, now taking place in Toronto, Ontario. It's the 40th anniversary. So this post tracks my lineup of sessions.


LOOK, I'M A FOOTNOTE!


1) Keynote: Stephen Lewis


Topic: Education: The World's Greatest Force for Good

Essentially talking about Math and Social Justice. Not hugely mathematical, but definitely relevant for EQUALITY. Just when you think we've come a long way, you hear about what's happening to women and children elsewhere in the world... or even close to home. (I still do not understand what's with all the rape cases making the media lately for the wrong reasons.)

Also, it's terrible how money tends to be the bottom line for anything. Particularly education, as strings get attached to loans, and what once was free is no more... is it any wonder Massive Open Online Courses (MOOCs) are seeing an upswell, given the cost of education in the world?

Takeaways:
-Education grips young children. Particularly those who haven't been able to experience it.
-There's enough injustice in this world already without creating more injustice.


2) My Session


Topic: Musical Mathematics

I actually missed a bit of the keynote making sure I was in a position to be able to present. ^_^ Had about two dozen people. Felt like my pacing was a bit off and I say "Uh" too much, but got a number of laughs, and the comments ranged from "Thanks" to "Outstanding", so I did something right. Good point raised as to how much the singing in class actually helps/correlates with results on quizzes and the like. Need to figure out how to gather that sort of data.

Takeaways:
-Someone out there is doing a music based math summative. I gave her my card, I hope she contacts me.
-My TMC13 presentation probably won't suck.


3) Featured Speaker: Dan Meyer


Topic: Making Math More Like Things Students Like: Video Games

The room had two screens, and they weren't synchronized, so Dan had to ask the audience for a second Mac projector adapter and coordinate two clickers. He started with some Angry Bird statistics, the answer to "How long will a student spend on a homework question until they know it's impossible" (12 minutes), and took a dig at Justin Bieber. (Meyer's more of a Ryan Gosling fan.)

Some key ideas (paraphrased):
"Make math more gamelike, not games more mathlike."
"Teachers risk not developing questions enough. We find the answers too exciting." (I am SO guilty of this at times.)
"A benefit of an open middle is that my way to solve [from beginning to end] may not be your way." (I love when a student does something different.)
"Adding a timed element only makes something more challenging, not more interesting." (I hate timed games. I don't play Set.)


IT'S DAN MEYER.   #DANMEYERFACTS #TWITTER

The six key video game elements to incorporate in math class:
1. Get to the point (as fast as possible).
2. Real world, bah (real is relative).
3. Have an open middle (self determination).
4. Grow more interesting as you grow more challenging.
5. Instruction is visual, only as needed, embedded in practice.
6. Reduce the cost of failure (don't lock in tests).


4) Featured Speaker: Jason Brown


Topic: The Connections Between Mathematics and Music

Pure tones are sine curves. Why are so many of our trig applications about angles, and repeated phenomena, and oscillating objects - and not music? Even the scale is taking a continuous blend of tones and making them discrete... based on ratios. In the equal temperament scale, that ratio is 2^(1/12), or the twelfth root of 2. (12 tones in a chromatic scale.) And why does the diatonic scale use the sequence 2212221 (TTSTTTS)? Due to network graphs that seek a "maximally even" orientation.

Some of that theory may have passed you by, so again, key ideas:
"Hearing 'beats' between two similar notes comes from a trig identity." (sin A+sin B=...)
HE WAS THERE WITH A WHOLE BAND

"Transformation is used all the time in music: move the motif up or down, reverse it, invert it, speed it up." ...Then show function notation? (Rap music generally only uses repetition, this may be why I personally find it less compelling.)
"Beatles tune 'I Wanna Hold Your Hand' uses f(x)=x-3; they don't start on the downbeat. You don't realize until they start the vocals, and your brain is fooled every time you hear the song, even if you know about it." (A constantly rising chromatic scale was also a brain teaser.)
"A 3 pattern versus 4 is a popular trick." (eg. Emphasize every 3rd note while bars are 4 beats. Resynchs every 3 bars.)

I actually got Brown's book as a gift for being a presenter (it was one of a few book choices), and he signed it for me. I bought his CD too: "Songs in the Key of Pi".


Miscellaneous


There was lunch there between the two featured speakers, after which I checked out some of the exhibitors. Renewed my OAME membership. Cube for Teachers is an online resource that tracks lesson items by Ontario Curriculum. Talked to the University of Guelph guy about a wallet card for Statistics. (And, I fear, stumped him when I asked how he would personify a Normal Distribution versus a Binomial Distribution.)

I was the guy at the start of the day who got the people in the Presenters room to post up the code for opening the MagLocked tech desks. Then at the end, I went to the Wine and Cheese and ended up talking more musical math. Now looking forward to tomorrow!
