This Week in Math Ed: February 17, 2017

Here's yet another abbreviated edition of TWiME.

Math Ed Said

February 10: People were sharing a recent interview with John Urschel from HBO's Real Sports.

Shared by: Andrew Gael, Andrew Stadel, Denise Spangler, Kristin Gray, Janice Novakowski, Sarah Bush, Kimberly Wassmuth, NCTM

February 11: Sometimes mathematicians play football, sometimes they do magic. "Raymond Smullyan, Puzzle-Creating Logician, Dies at 97" wrote the New York Times. Here's a 1982 appearance by Smullyan on The Tonight Show:

February 12: I'll admit, I don't know exactly why people were sharing Sara VanDerWerf's "Secondary Number Talks (I'll convince you with ducks)" post from last year. I can only say it was a good post then, and people obviously think it's still a good post now.

Shared by: rosa, Susan Davidson, Ben Braun, Kate Nowak, Geoff Krall, Lisa Bejarano, Morgan Fierst, Melinda Knapp, Nicole Bridge, Amanda Jansen

February 13: People were sharing the Washington Post story, "Justice Department warned White House that Flynn could be vulnerable to Russian blackmail, officials say."

Shared by: Ilana Horn, Spencer Bagley, John Allen Paulos, Keith Devlin, Mister Ed, Matthew Haden

February 14: Another day, another political story: "Trump Campaign Aides Had Repeated Contacts With Russian Intelligence."

Shared by: Keith Devlin, Paul Morris, Kathy Henderson, Mister Ed, John Allen Paulos, Spencer Bagley, Samuel Otten, Kenneth Tilton, Kay Endriss

Comment: It seems one or two political stories make their way into TWiME each week, which is lower than I'd imagine given how much attention politics is getting on Twitter. I think math still surfaces to the top in TWiME because there are so many political news outlets that the same links aren't shared by everybody.

If you really want something math ed and Russia-related, maybe you should check out the work of Daniil Elkonin (1904-1984) and Vasily Davydov (1930-1998), students of Lev Vygotsky. I don't know all that much about them myself, but the Encyclopedia of Mathematics Education tells me that Elkonin and Davydov an approach to learning math built on two principles: (1) dialectical logic, where general ideas are established before more advanced, specific ideas are developed, and (2) learning from one's own activity and building mathematical ideas from their origin. Like I said, I don't know all that much about Davydov, but I can already tell that I'd need to read a lot more about this before those two principles would make sense to me. But if you wanted something Russian but also math ed, that's what came to mind.

February 15: Robert Kaplinsky warned us to Beware of Fake Math Modeling Problems." Robert finds an example where modeling seems to partly be the "smaller version of" kind of modeling, and then the questions students are expected to answer really aren't there to help them understand what's happening in the thing they're supposed to be modeling.

This Week in Math Ed: February 3, 2017

I haven't had much work time to keep up with the goings-on in the math ed community, and I've been spending more of my evenings and weekends dissertating instead of blogging. (Gotta graduate sometime!) I'm way behind on TWiME, but I have been able to grab the the most-shared posts on my math ed Twitter list each week. I may not be able to make time to dig into all the latest news and research, but I can at least share this.

Math Ed Said

January 27: Jose Vilson talked about writing with the Global Math Department in a session called "Writing: Your Questions Answered."

Shared by: Bridget Dunbar, Sahar Khatri, Heather Kohn, Sharon Vestal, Jose Vilson, Global Math

Shared by: Spencer Bagley, Sahar Khatri, Keith Devlin, Earl Samuelson, Karen King, Zach Cresswell

A creatively-drawn congressional district in California.
January 29: As the saying goes, gerrymandering is when politicians choose their voters instead of voters choosing their politicians. If you're thinking there should be a mathematical solution to this problem, then you're likely to learn about it during a 5-day summer session at Tufts University called Geometry of Redistricting. The session is August 7-11 and applications are open until March 15.

Around the Math Ed Web

Are you a college instructor wanting to know more about inquiry based learning? You might want to check out these IBL summer workshops at DePaul, Cal Poly, and Nazareth College.

I'm not interested in sharing information about every math-related webinar and MOOC, but the set of offerings from the Place @ the Friday Institute has a set of courses designed specifically for math teachers and their courses are beginning now.

I'm having trouble with the Global Math Department conferences on BigMarker right now, but trust me, they're still hammering out the dents in math ed every Tuesday night.

Research Notes

To save myself a little time in the research notes, I may not always list the institution of each author. Some journals make it near-impossible to copy and paste this from the article page — looking at you, Taylor & Francis!

Colorado Academic Standards Review & Revision

The first monthly informational webinar about the review of the Colorado Academic Standards will be Tuesday, February 7, from 3:30 to 4:30. Connection information can be found on the CDE website.

CDE continues to collect standard-specific feedback using an online standards feedback system. This is a unique opportunity for any Coloradan to provide line-by-line recommendations that will be considered by the standards review committees. All forms of feedback are welcome: if you think something should stay as-is, be revised for clarity, moved to another grade, or removed altogether. Do not let this opportunity pass if you have ideas that you think should be considered! The online standards feedback system will be open through Sunday, April 30, 2017. This end date has been extended again because your input is so critical to the review and revision process.

Colorado Revised Teacher Rubric

CDE's Educator Effectiveness unit is collecting public feedback about its teacher rubric. See here for dates and locations of focus groups (must register by 2/24) and an online form to submit specific feedback about the rubric.

Girls Lead the Way

Monday, January 30th is the deadline to register 9th-12th grade girls for the Girls Lead the Way Leadership Conference. The conference is February 11 at the Colorado School of Mines in Golden.

January 16: In a post that's sort of about baking, and sort of about a book, but not really about either, Christopher Danielson gives us "Muffins, math, and the lies we tell about both."

Shared by: John A. Pelesko, Judy Larsen, Sharon Vestal, Justin Lanier, Michelle Naidu, Mathalicious, Ilona Vashchyshyn

January 17: Kristin Gray's post on the Teaching Channel is about "Lesson Study: Choosing a Mathematical Goal and Task." It's the first in a series, so be prepared to read, be given something to think about, and return for the rest of the discussion.

Shared by: Lisa Melton Pizzuto, Rosa Serratore, Julie Kubiak,David Petersen, Illustrative Maths, Andrew Gael, Sadie Estrella, Kristin Gray

Fawn Nguyen at the 2016 NCTM Innov8
January 18: If you're wondering why Fawn Nguyen's "Growth vs. Proficiency" post from last August would suddenly get attention, it all relates to a question asked by Senator Al Franken during Betsy DeVos's confirmation hearing to be Secretary of Education. DeVos didn't appear 100% prepared to answer Franken's question, which sent members of the public to the internet to see if they couldn't figure out what the whole growth vs. proficiency debate was all about.

Shared by: Kevin Lawrence, Jennifer Dao, Patty Stephens, Andrew Gael, Ilana Horn, Casey McCormick, Fawn Nguyen, Earl Samuelson

January 19: Folks were still talking about Fawn's post, but there was also notable sharing of "The Teach to One Math Experiment in Mountain View, CA Is a Trainwreck."
