[Help Wanted] Can I Get Your Feedback On

MathRecap is a project in modernizing and increasing access to math education conferences. I and my fellow recappers concluded our coverage of CMC-North last week. How did we do?

On the one hand, our most trafficked recap, Lisa Nussdorfer’s iPad session, received 538 unique pageviews, which means many more people had access to her talk than just the thirty of us in the classroom where she was scheduled. That’s great.

On the other hand, traffic wasn’t so explosive that I’m convinced this kind of site is as useful as it can be. So I’m inviting your commentary: What would make a conference recapping site most useful for you? If it isn’t something you find useful, why not?

NCTM is in four months. That’s a pricey ticket and many of you aren’t attending. So what can a site like MathRecap do for you?

Featured Comments

David Wees is the first to say that MathRecap wasn’t well publicized:

This is the first I’ve heard of the site, so I missed the announcement somehow, so maybe people just don’t know about it? I’ve added it to my feed though, and included it in my list of mathematics education blogs.

Jason Dyer:

I had no idea how what was being discussed translated into classroom practice, what “culturally relevant pedagogy” looks like past one ambiguously phrased word problem, and how the standards of mathematical practice are linked.

Michael Pershan:

Blog posts are good. Presentations are good. But what is each format particularly suited to do? In particular, what gets lost when you try to translate a presentation to a blog post?

[Help Wanted] Does The Medium Matter?

2011 June 13: No more help needed on this one. Thanks for piloting this study for me, team.

If you’re still in school, if you still have students around, I’d be thrilled if you’d help me answer a question that’s nagging me.

If you pose this question to a student:

It took Michael Benson six minutes to run one mile in a timed trial at his school – his fastest time ever. How long would it take him to run a 26-mile marathon?

Does the student multiply six by 26 getting 156 minutes? Or, more sensibly, does the student multiply six by 26 getting 156 minutes and then add some time to compensate for the fact that Benson isn’t going to be able to maintain his fastest time for one mile over 25 more of them?

My speculation is that math class pretty effectively conditions that sensibility out of a student by the fourth or fifth grade. It’s very difficult to succeed at math class if you don’t train yourself to ignore entropy, gravity, friction, and a million other factors mitigating these tidy word problems.

But does the medium matter? If you present those two sentences in black and white on paper, are the results worse than if you present them in a medium that’s more befitting the context? Like a video? Or a newspaper clipping?

How You Can Help Me

  1. Print out equal numbers of these four pages. They’re four different versions of the same question.
  2. Shuffle the four versions and pass them out randomly, in equal numbers, to your students. (Doesn’t matter to me if this is calculus or sixth-grade math. The more classes the better.)
  3. Tell them you can’t answer any questions about the problem. They should write those questions down. Let’s leave calculators off the table. Ask them to do their best and to be sure to write down their reasoning.
  4. Give your students as much time as they need to do this one problem.
  5. Collect the papers.
  6. Get the papers back to me:
    • via email:
    • via fax: 831.325.0095
    • via mail: PO Box 429, Mountain View, CA 94040

I’ll need to know the letter grade of each student, too. And the course they’re taking. Can I get any volunteers to raise a hand in the comments? I’m not going to pretend this isn’t a huge favor. You can consider me in your debt.

2011 June 7. To clarify, would you be sure to send the forms back without the student names. Feel free to just attach numbers to the top. (“Student #1,” “Student #2,” etc.) Or anonymize them in some other way. I only need some way to link the student’s response to her overall class performance.

[Help Wanted] Seattle Qwest Stadium Beer Cups

Are any of my readers headed to Seattle’s Qwest Stadium anytime soon? If you are, see if you can score a small and a tall beer cup and take them home. If you’re game, I need three photos:

  1. the menu with beer prices visible.
  2. both cups side-by-side on a counter.
  3. both cups side-by-side on a counter with a centimeter ruler in the same visual plane.

And, yeah, my request ticket has everything to do with this fantastic clip:

[BTW: Bummer. Qwest has already pulled my math unit. Gotta admire their spin, though. “We weren’t ripping off the tall-cup customers. We were giving the short-cup customers a bonus!”]
