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.


  1. Dodge-ball leads to edu-plunk.
    Teacher with a donut and a cup of coffee = edu-dunk.
    Teaching in a cave = edu-spelunk
    Teacher got back = edu-badunk-a-dunk. (ba-donk?)
    Not so bright teacher = edu-lunk
    Teaching with a grease stain on your shirt = edu-gunk
    Teaching underwater = edu-sunk

    O.k. — I need to stop.

  2. Teacher forgets deodorant: edu-skunk

    OK…my bad. Thanks for providing the nice satire of the overuse of the edu- prefix. Next thing you know they’ll be selling edu-water at edu-stands while you edu-blog from your edu-phone.

    Edu! (Adieu!)

  3. Teacher doesn’t get it. Clueless.

    The teacher’s understanding is absent and attempt to convey is so inaccurate as to be clown-like. Students are provided with an inadequate education by their “professor“.

    That’s so eduflunk.

    “Hardcore” if it occurs under high-stakes testing situations.

  4. Ok, no blackboards, whiteboards, writing utensils…I get the progressively ascetic mystique… but where are your *arms* in this picture? No arms??! I don’t know if I can get on board with that one, frankly.

  5. Strange, I know, but I’ve thought about Peter’s comment here for several days. The good news is that I have a solution for you, Dan, unless the bad news is actually true.

    The solution: Install Scoble’s auto Twitter follow script somewhere, follow everybody that follows you. You look like a nice guy and don’t have to pay attention to anybody’s tweets. You’re a smart coder, you can do it.

    The bad news which may or may not be true: Your inability to follow others on Twitter is probably some strange experiment in egocentricity.

  6. Twitter is my microblogging platform of choice. Do you subscribe to everyone who subscribes to your blog? I mean, would you if you could?

  7. @dan: Fair point, but I imagine that you *do* subscribe to some of the people who read your blog. Or you at least subscribe to a few other blogs. (Unless your sidebar is a lie) you could think about doing something similar with Twitter, subscribing to a *few* of the quality tweeters.

  8. I subscribe but I don’t follow. I’d rather read them in my reader than feel obliged to monitor incoming tweets second-by-second. Again: it’s just microblogging to me.

  9. Arthus,

    Those that actually read others’ work have learned that Twitter is far more than “What are you doing now?”, not just another form of microblogging, and more of social network utilized for interaction than some online form for spewing occasional thoughts.

    Don’t let anybody tell you differently.

    As a side-note, I’m beginning to believe that the bad news I offered before actually is true.

  10. Arthus,

    Don’t let anyone tell you that you must enjoy the Internet exactly as they do.

    Darren, for whatever it’s worth, I realize the average Twit gets a lot more fun out of Twitter than I do, that I’m not taking part in all the social interaction. But I don’t want it. As a level-ten introvert, my social needs are filled and then some by my small crowd of flesh-and-blood friends.

    So egotism? Your call. At a certain point in all this Twitter nonsense I had to shrug and just let the haters hate.

  11. Darren: I know. That’s why I participate pretty actively in Twitter with a decent number of followers/people I follow.

    dan: Isn’t that the beauty of the Internet? You can find what *you* want to do with it, and I can do my own thing.
