This Week in Math Ed: January 12, 2018

I don't think I'll need or be able to scour 35+ research journals every week for new articles, so maybe I'll try to do that every other week, or maybe once a month. In any case, here's some of what was popular in the world of math education for the week of January 5th to January 11th, 2018.

Math Ed Said

January 5: This article appeared once here last week, and now it appears twice this week: Sunil Singh's "Six Questions That Math Educators Need To Answer Honestly." My short answer to Question 1, "What is mathematics?": Mathematics is the human activity of reasoning with number and shape. A slightly longer answer would explain that this reasoning produces the artifacts that we associate with mathematics, but particularly as an educator I keep the definition focused on math as a human activity, as Freudenthal did.

January 7: Heidi Fessenden wrote "Counting Collections: One Nearly-Perfect Answer to Inclusion," a reporting of what's happening with her students when children with and without autism pair up to count collections of objects. Heidi is a thorough storyteller and it's a story I needed to hear, as I've been helping write a state policy document for students with disabilities and stories like this keep my head rooted in practice.

Is your district making segregation worse?
January 8: Want to get lost in some policy, maps, and data? Spend your time on this feature from Vox: "Mapping the imaginary lines we use to segregate our schools." Based heavily on some new work by Berkeley PhD candidate Tomas Monarrez, you can use this tool to explore segregation patterns in districts across the country and understand the policies and historical reasons that shaped them.

January 9: If you missed it on the 8th, here it is again on the 9th: "Mapping the imaginary lines we use to segregate our schools."

Shared by: Morgan Fierst, Kara Imm, Dylan Kane, Elizabeth Self, Samantha Marshall, Karen King, Theodore Chao, Thad Domina, Tyrone Martinez-Black, Heidi Fessenden

January 10: After spending all that time looking at segregation patterns, give yourself a chance to chuckle with Ben Orlin's "Compass Constructions Made Easy."

Shared by: Anna Blinstein, Nathaniel Highstein, Chris Burke, Jo Morgan, Ilona Vashchyshyn, Denise Gaskins, Ryan R Ruff, Jennifer White, Jennifer Lawler, Jen Silverman, Ben Orlin, Michael P Goldenberg

January 11: There's probably a context to this I missed, or maybe this is a new feature: A Desmos graph where the Desmos logo spins around.

This Week in Math Ed: January 5, 2018

My blogging dropped off in 2017 at the end of April, which coincided with the ramping-up of Colorado's review and revision of our academic standards. I kept telling myself, "If I just get a little more organized and motivated, I'll get back to blogging," but the reality was that my priorities just didn't (couldn't?) have blogging near the top. We're still in the process of reviewing and revising standards, but with a new year I decided it was time to renew my blogging efforts. Here are the highlights of the mathematics education world for the week of Friday, December 29, 2017, through Thursday, January 4, 2018.

Math Ed Said

December 29: Caitlin Tucker wrote "Battling Against Traditional Perceptions of Teaching and Learning," where she addresses the challenges of facilitating a student-centered classroom with students who either expect or prefer that activity is focused on the teacher.

Commentary: I experienced these struggles teaching a college intro to stats class, and some of my students were experienced teachers themselves in a master's program! When one of my students, who is a teacher, called me over during group work to tell me, "I know how to teach math, and you're doing it wrong. You need to be working examples at the board and giving us sets of similar problems to practice," I couldn't help but feel that our expectations were so far apart as to be unbridgeable, and that's a horrible feeling for a teacher to have.

December 30: Steve Wyborney shared "Cube Conversations," a large set of activities for students that give them practice visualizing, reasoning with, and discussing three-dimensional constructions of unit cubes.

Shared by: Rene Grimes, Kit, Lindel, Kat Hendry, Kit, Jon Orr, Richelle Marynowski, Robbyn Glinsmann, John Faig, Kyle Pearce, Steve Wyborney

December 31: Hmmm. Chalkbeat is holding a live event at SXSW EDU called "The Great American Teach-Off," where two pairs of elementary math teachers will execute some sort of teaching challenge on stage for a panel of judges. The organizers wish to highlight in public more of the work of teaching. If you wish to give it a go, the instructions for applying are at the link.

RYSK: Gutiérrez's Political Conocimiento for Teaching Mathematics: Why Teachers Need It and How to Develop It (2018)

Rochelle Gutiérrez keynoting the 2016 CCTM Conference
I haven't used the "RYSK" tag for a blog post in almost four years, but only because I've taken to summarizing research over on the MathEd.net Wiki. That wiki turns five years old this month while this blog turns eight! I think my best strategy is to summarize on the wiki and editorialize here on the blog, and the events of this week demanded that I break my blogging silence and deal with an issue of the moment.

Last Monday I was riding the bus home when Google stuck an article from an anti-liberal education site called Campus Reform into my news feed. It was about a math education professor and white privilege, so I checked it out (in incognito mode — I try not to give Google the wrong ideas about the sites I want more news from). The article was about Rochelle Gutiérrez and honestly, it didn't say all that much except to highlight connections Rochelle was making between math and white privilege. The comments below the article were...what you'd probably expect. I closed the story and didn't think much about it, other than, "I wonder if this story will go anywhere?"

Go somewhere, it did. On Wednesday Google showed me that Fox News had picked up the story. Predictably in this era of internet news, it wasn't original reporting on the content of Rochelle's work. It was just a rehash of the Campus Reform article and it was getting a lot of comments. Judging by what I was seeing, the Fox News patrons didn't seem to have read Rochelle's work either. I searched Twitter for use of Rochelle's handle and saw she was getting a lot of negative comments with some blatant harassment thrown in (I reported one person whose account was subsequently found in violation of Twitter's rules). Those people didn't appear to have read Rochelle's chapter, either. (A notable exception: Jason Miller's post and conversation on Google+, which took the rational approach of asking "Does anyone know more about this?" and got replies like, "Here's more info, but not enough to draw conclusions." Score +1 for Google+.)

If I've learned anything in 2017, it's that I need to be upset/outraged on my own schedule and on my own terms. That usually means doing more listening and learning and not jumping into a soon-forgotten online fray. So I ordered the book Building Support for Scholarly Practices in Mathematics Methods, in which Rochelle's chapter appears, and waited a few days for it to arrive so I could actually read it before commenting.

I've now read and summarized the chapter on the MathEd.net Wiki. Did Rochelle link the privilege of mathematics to the privilege of being White? Did she say we perpetuate that privilege when we focus on Greek mathematical history and not that of other peoples? Did she say we should see mathematical knowledge is relational, and not objective? Yes, she did say all those things, and in that way the original Campus Reform article was mostly accurate. Where it wasn't accurate — and led many other sites and their audiences astray — was representing Rochelle's chapter as mostly about those things. Rochelle made most of those statements in a page or two, then spent the rest of her 27 pages laying out a framework of teacher knowledge meant to help prospective teachers deal with the political realities that affect their work.

What strikes me after reading the chapter is that Rochelle names many political influences on teaching and education that are also common targets of the right: Common Core, Pearson, big philanthropic foundations, bureaucratic inefficiency and misdirection, and control of schools that doesn't reflect local needs. There is plenty of common ground to be explored in the chapter if people choose to look for it and discuss it. The news sites could have done that, but they didn't. It wouldn't be sensational enough to generate traffic and ad revenue, and their typical narrative doesn't leave room for discussing the development of political knowledge meant to benefit traditionally underserved students.

Now that things have (probably) quieted down, we can look at Rochelle's chapter for the reasons she wrote it: to inform math teacher educators who want to help prospective teachers deal with the political pressures and distractions that can interfere with giving students the help they need. If you are a math teacher educator, this looks like a book you should have. I've put the table of contents on the wiki along with the summary of Rochelle's chapter.
