I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.

DFW, one

Josh Dean, NYT editor, explaining DFW’s particular literary gift:

But the thing that always struck me was that he could sizzle your synapses with intelligence and insight and literary pyrotechnics, but you didn’t need to read his sentences twice. They were brilliant and also colloquial. How he pulled that off is a literary voodoo I might never understand.

Kathleen Fitzpatrick, DFW’s Pomona College colleague, letting me pimp my favorite author and my favorite tv show all in the same post:

He was, in fact, extremely fond of The Wire — he stopped me in the hall one day last year and said, look, I really want to sit down and pick your brain about this, because I’m really developing the conviction that the best writing being done in America today is being done for The Wire. Am I crazy to think that?

David Foster Wallace, himself, explaining his respect for and the essence of good teaching:

It might be that one of the really significant problems of today’s culture involves finding ways for educated people to talk meaningfully with one another across the divides of radical specialization. That sounds a bit gooey, but I think there’s some truth to it. And it’s not just the polymer chemist talking to the semiotician, but people with special expertise acquiring the ability to talk meaningfully to us, meaning ordinary schmoes. Practical examples: Think of the thrill of finding a smart, competent IT technician who can also explain what she’s doing in such a way that you feel like you understand what went wrong with your computer and how you might even fix the problem yourself if it comes up again. Or an oncologist who can communicate clearly and humanly with you and your wife about what the available treatments for her stage-two neoplasm are, and about how the different treatments actually work, and exactly what the plusses and minuses of each one are. If you’re like me, you practically drop and hug the ankles of technical specialists like this, when you find them. As of now, of course, they’re rare. What they have is a particular kind of genius that’s not really part of their specific area of expertise as such areas are usually defined and taught. There’s not really even a good univocal word for this kind of genius–which might be significant. Maybe there should be a word; maybe being able to communicate with people outside one’s area of expertise should be taught, and talked about, and considered as a requirement for genuine expertise.

Sorry if this place gets a little funereal or mushy as I push through a lot of interviews, a lot of eulogies, and his entire published body of work. You should start with Shipping Out: On the (nearly lethal) comforts of a luxury cruise, recently made available free online by Harper’s Magazine.

Math Basketball

I was digging through the dy/dan mailbag today and found a note asking me to explain what I have often referenced on this blog but never clarified. I swear, there isn’t any activity my kids enjoy more than basketball review. Here’s how it works:

Instructions

  1. You bring in a set of questions related to the previous two week’s instruction.
  2. You put up a question.
  3. A kid stands up with an answer, either correct or incorrect:
    • If it’s incorrect, the student sits down, reworks the problem, and you wait for another student to stand.
    • If it’s correct, the student takes two shots with a miniature basketball into a lined trashcan. You award points according to a) the student’s distance from the trash can, and b) the competitive mode you’ve selected below.
  4. Repeat.

Competitive Modes

I have used four, each with their own recommendations. Listed in descending order of popularity:

  1. Class v. Teacher. The students take two shots for every right answer. The teacher takes one shot for every wrong answer. Highest point total wins either extra credit (for the class) or bragging rights (for the teacher).
  2. Class v. Class. One side of the class versus the other. Seed them by mathematical and athletic ability. Highest point total wins extra credit for their team.
  3. Free Market Capitalism. Everyone for him- or herself. Good for the final minutes of class. A student receives as many extra credit points (or pieces of candy) as he or she can score.
  4. Class v. Arbitrary Point Total. If you’re averse to classroom competition, let the class play as one, studying and shooting to pass an arbitrary point total.

Other Release Notes

  • Have the students turn in a paper with all their work on it. I make a big deal about this so everyone works the math through even if they don’t all shoot. Toss these papers after the last student leaves.
  • Encourage shy students to answer math questions and pass off the ball to another student if they don’t want to shoot.
  • Once a student successfully answers a question, she can’t answer again until the rest of her team answers, though she must still work through the problems.
  • Student conference is way out of bounds. If the idea is that everyone works hard on the math, allowing one student to source all the answers would be counter-productive. If I catch anybody whispering answers, I give the other team a shot.
  • Introduce an extraordinarily difficult and extraordinarily valuable shot halfway through the term, a 20-point shot through an open window, for instance.
  • In between the math review, toss in some extraneous nonsense. Name that flag, for instance.

    You can find these slides anywhere “basketball” is listed in my Geometry supplement.

Best Post Of The North American School Year To Date

I subscribe to eighty-something education blogs which push me several dozen posts per day and yet my reader goes these through long, arid stretches – nothing but conference session recaps, pie-in-the-sky tech idealism, policy wonks talking over each other, endless unedited malformations from people (teachers) who probably oughtta know better – where nothing manages to connect even loosely to my practice, where nothing manages to connect even loosely to my experience as a teacher.

Todd Seal’s post, No Idea, cut through all that blogospheric flotsam tonight like an arc torch and left me nodding my head, mumbling “yeah, uh huh, yeah,” at my iPhone as I waited in line for my wife to make a return at Urban Outfitters. Wherever you can find it, right?

Todd:

When I close that door, I’m on my own. I’ve got fifty-three minutes with a group of thirty kids who want entertainment if they want anything. I need to take those kids wherever they are and help them improve by the time they walk out the door. I need to give them at least one new idea today and one reason to come back tomorrow.

I have no idea what I’m doing.

The stuff that makes you believe in blogs again.
