This Week in Math Ed: June 17, 2016

Math Ed Said

June 10: With one of the most purely geeky things to appear in TWiME, a number of people shared "41 triple pendulums with very slightly different initial conditions." In animated GIF form, no less.

June 14: The first mention of Hacker's Math Myth was on February 7 and I've lost track of how many times this topic has resurfaced in TWiME. This time, it's A.K. Whitney's "Why Andrew Hacker Is Wrong About 'The Math Myth'" in The Atlantic. Whitney concludes by saying, "I fear this debate will just rage for another 100 years," which is what I'm feeling, too.

June 15: "Numbers are just empty vessels into which we pour our meanings, and they always overflow," says Ben Orlin in "50 Killed, or 49?."

Shared by: Ilona Vashchyshyn, Meg Craig, Ben Orlin, James Cleveland, Anne Schwartz, Andy Shores, Jonathan Edmonds

June 16: Dan Meyer wrote "Your GPS Is Making You Dumber, and What That Means for Teaching," which spurred resharing on Twitter and a lot of comments on the post itself. My amazement: All this talk of two approaches to learning math and a navigation metaphor and not a mention of Skemp's analogy to be found.

It turns out there wasn't a Global Math Department talk last week, but Sara Van Der Werf is scheduled to talk about "The Pursuit of 100% Engagement: Practical ideas to get you closer" on Tuesday the 21st.

We're still waiting to hear about NCTM Research Conference proposals, but you can submit for RUME until August 19 (or December 2 for posters).

Research Notes

It was an unusually slow week on the research front, but here's an article about Common Core and developing instructional capacity that just appeared in AERA Open:

June 3: The Math Munch for June 2, "SET, Ptolemy, and Malin Christersson," was the most-shared item on the 3rd.

Shared by: Justin Lanier, Ilona Vashchyshyn, Jeremiah Ruesch, Anna Weltman, Denise Gaskins, Julie Wright

June 4: Ryan Dent shared "Teachers understanding progressions...and kids that are "behind" in what appears to be his first blog post (at least at this site). This post reminds me of a recent university seminar presented by a math educator to non-math educators. When the math educator described having teachers engage in math tasks for professional learning, a non-math educator remarked, "I'm really surprised that you'd have them do that. I assumed math teachers know their content and there'd be nothing to discuss."

Shared by: Laura Wagenman, Ryan Dent, Jamie Duncan, Levi Patrick, Mike Anderson, Lindel

June 5: Terence Tao mixed politics and logic in his post, "It ought to be common knowledge that Donald Trump is not fit for the presidency of the United States of America."

Shared by: Ken W. Smith, Justin Lanier, Tom Henderson, Spencer Bagley, Evelyn Lamb, Egan Chernoff

June 6: A short interview with Matt Larson appeared on the Curriculum Matters blog at Ed Week: "New NCTM President: Math Is About More Than College and Career Readiness." In the interview, Larson emphasizes math as a path to democratic citizenship and making NCTM more responsive to its members.

Shared by: Jon Wray, Glenn Waddell, Jr., Denise Spangler, NCTM, Greg George, Farshid Safi, Melissa Haun

June 7: Chris Lusto spurred a lot of great conversation last week with his post, "Lessons for Other People." As someone who likes to think about and build infrastructures for curriculum materials, and who researches curriculum adaptation, I'm very interested in how to make lesson repositories more useful, and how to make the materials they contain high quality without losing their perceived malleability. That's not an easy balance to achieve. I'm also in a position where I'm not thinking about a lesson written or adapted by one teacher for one classroom. I'm more likely to ask the question, "How can we capture this teacher's adaptations of their lesson so they might benefit a different teacher using the lesson five years from now?" None of these have easy answers, but you'll want to check out Dan Meyer's response as well as one from Max Ray-Riek.

AMTE President Christine Thomas wrote about a possible reforming of the Mathematical Sciences Education Board, which has been dormant at the National Academies of Sciences, Engineering, and Medicine for a decade. AMTE also released survey results about enrollment in mathematics teacher preparation programs.

At the Global Math Department this week you can listen to teachers share their favorite strategies for handling the end of the school year. If you missed it, last week's talk by Roni Ellington about a discourse framework for access, equity, and understanding has been posted to the site.

June 2: In another Desmos story, Ontario has approved the use of Desmos for a standardized math exam. Previously used in Texas, this enables an exam mode in Desmos that constrains use of the app in ways that allow it to replace a traditional graphing calculator in a testing environment. I thought TI might do this themselves with their own software, but thankfully Desmos is providing some needed competition in the calculator market.

May 25: Jamie Duncan wrote "First Grade Fraction Talks... What?." I wondered how she did this without straying too far from the Grade 1 standards, but I think she did so rather nicely — there's no use of fraction notation, and students reasoned their way by focusing on the number and relative sizes of shapes.

I'm keeping this very short and very simple this week: Last week's Global Math Department talk is here (on interleaved problems), this week's is here (on the math behind game shows), and be aware that due to technical difficulties, NCSM has extended their proposal deadline for next year's annual conference to June 3rd.

Research Notes

The first few articles have been added to the September 2016 volume of The Journal of Mathematical Behavior:
In what's being called "Volume 2, Issue 2 Supplement" for July 2016 (rather than Issue 6, I guess, which would have been next), here's more from the International Journal of Science and Mathematics Education:
Here's something mathy and new from Teaching and Teacher Education:
The University of Exeter reorganized their website and wiped out Paul Ernest's archives of the Philosophy of Mathematics Education Journal. I found Ernest's new faculty page and hope an updated link appears there soon.

May 13: The first time I saw "WODB" (Which One Doesn't Belong?) mentioned on Twitter, I wasn't quite sure what to make of it. But when you see it in action, skillfully facilitated, you get it. Tracy Zager shared with us "Straight but Wiggled," in which a bunch of first graders make sense of ideas like "diamond," "straight," and "vertiwiggle." If you're familiar with Paul Cobb et al.'s work on the emergence of sociomathematical norms in classroom group activity, it makes it extra interesting to see what happens here.

May 16: Jon Orr describes "Double Clothesline – Solving Equations," a very nice approach to understanding solving equations. Instead of a balance or algebra tiles, this uses double number lines in a way that gives more focus to the quantitites, rather than choosing or performing operations.

Dan Meyer
May 17: Dan Meyer is thinking about the informal that supports the formal understanding, which he illustrates in the post "Blue Point Rule." This is familiar territory for those of us who study Realistic Mathematics Education and its approach of progressive formalization. RME uses the terms "informal," "preformal," and "formal," and what Dan's wrestling with is what I'd call the "preformal" in RME. It's important that we call it out because it's really tough to make that last transition from a preformal model or conception to the use of a formal equation or rule. Dan's collecting "Before I ask for (Formal X), I ask for (Informal Y)" statements, some of which hint at common models used in RME.

May 18: There were 14 more shares of Dan's "Blue Point Rule" post, but I didn't want that post to completely overshadow this post by Matt Larson, which also got (re)tweeted a lot on the 17th and 18th. "NCTM Is Its Members" talks about NCTM understanding the needs of its members and what they're doing to meet them. I'm pretty excited about some of the directions NCTM is going, and they're moving a bit faster than I expected when I was thinking about these issues a while back. If you have feedback and ideas for Matt and NCTM, be sure to go to the post and leave them. You can see what other people have said and Matt's replies, and it looks like a pretty good discussion so far.

A few more links popped up this week that I think are too good to pass up:
I'm eager to listen to Sam Otten's podcast with Thomas Carpenter. The episode is 28 minutes long and if I had 28 minutes to talk with Tom Carpenter, I probably wouldn't get past 1970. I'm guessing Sam did better than that.



In the Global Math Department last week, Tracy Zager gave a talk called, "How Do They Relate? Teaching Students to Make Mathematical Connections." Next week, Yana Weinstein and Cindy Wooldridge will talk about "Improving Math Education with Interleaved Problems by Global Math Department."

Deadlines: NCSM Annual on June 1 and RUME on August 19th and December 2nd (for posters).

Math Ed in the News

Do you remember that thing I put in last week's news section? No, you didn't, because there wasn't a news section! Somehow it slipped by unnoticed. But here's some news for you this week:

Math Ed in Colorado

The highlight of my week was attending the Colorado Mathematics Awards at the Grant-Humphreys Mansion in Denver. Organized by Richard Gibbs, David Carlson, and the CMA steering committee, this event recognizes students for outstanding performance in MATHCOUNTS, the American Mathematics Contents 8, 10, and 12, Moody's Mega Math Challenge, the USA Mathematics Olympiads, the American Regions Mathematics League, the William Lowell Putnam Mathematical Competition, the International Contest in Modeling, the Interdisciplinary Contest in Modeling, and some teaching awards. Whew, did I remember them all? It was great to see students ages middle school through college all being recognized for their outstanding work, and the fact that Colorado has a special event that brings all these people together is really something to be proud of.

The packed house at the Grant-Humphreys Mansion for the 2016 Colorado Mathematics Awards

While it was great to join everyone in this event in its 21st year, I think a big challenge going forward is to make sure opportunities to participate on math teams and in math competitions gets spread across all of Colorado. As a former MATHCOUNTS kid from a 5200-person rural town in Iowa, I noticed that most of the awardees were students from large, high-SES schools on the Front Range. I realize I only saw the winners, not all the participants, but the small-towner in me would love to see some students there representing places like Gunnison, Ordway, and Walden. Geographic diversity is one of a number of struggles concerning math competitions, so if you'd like to expand the opportunity to participate in math competitions at your school, let me know and I'll see if I can get you connected to people who can help.
