July 18: There was a tie between six different posts shared five times each, but the only math-focused on with new content was "10,000 Kicks: Practice in the Mathematics Classroom," an NCTM Mathematics Teacher blog post written by Tim Hickey, a high school math teacher from Virginia. The post struck a nerve with some, as the math community is hardly unified when it comes to the issue of worksheets and practice. NCTM's choice to publish and promote this is an example of the growing pains I think we'll see as they try to give more voice to their members and those members do not all agree.

This Week in Math Ed: July 15, 2016

Math Ed Said

July 8: A New York Times op-ed says we should "Train Teachers Like Doctors." They make an important point: teachers with high-quality resisdency (student teaching) programs tend to stay in the profession longer. With teacher education enrollment currently in decline, it's a high priority to keep the teachers we are producing in the profession longer.

July 9: I'm not exactly sure what triggered the resharing of this 2011 blog post (an Alfie Kohn tweet, possibly?) but it gets at one of my pet peeves about how objectives are presented in the classroom. In "Objectively Speaking," Mike Fishback argues against the posting of learning objectives to begin a lesson, saying it takes away from students' agency as learners. I agree, especially when this happens in the form of, "Okay class, take out your notebooks and write down today's objective." If you can instead get to "Okay class, given what we did the past few days, what do you think we need to figure out next?" and build a common understanding around that, then that's a very different way of establishing the lesson's objective.

July 10: I'll give you two to choose from, each shared by four people:
  1. "To White Teachers Shouting 'Black Lives Matter.'" by Tom Rademacher
  2. "Critical Thinking in Academia and Calling a Spade a Spade" by Rafranz Davis
Shared by: (1) Bryan Meyer, Brian R Lawler, Chris Adams, Martin Joyce; (2) Nancy Terry, Kate Nowak, Ilana Horn, Nolan Doyle

Sumaze!
July 11: People were talking about Sumaze!, a problem-solving app from MEI and Sigma Network. I don't spend enough time testing out math-related apps, but I'm glad I checked out this one. (Opinion: The quality of the math far exceeds the quality of the music. But that's better than many math apps which are the opposite!)

July 12: Suzanne Alejandre announced that there is a Math and Social Justice Q&A now on The Math Forum.

Shared by: Suzanne Alejandre, Max Ray-Riek, Sadie Estrella, Sahar Khatri, Julie Wright

July 13: For this month's #TCMchat, the discussion revolved "13 Rules That Expire", a Teaching Children Mathematics article by Karen Karp, Sarah Bush, and Barbara Dougherty.

Around the Math Ed Web

Math Twitter is abuzz with posts from TMC, being held this year on the campus of Augsburg College in Minneapolis, MN. You can follow the #TMC16 hashtag, and Stacia McFadden created Storify posts for the morning and afternoon of Day 1 and the morning of Day 2 (so far).

Math Ed in the News

It's that time of the summer where some weeks go by without much math education coverage (or good coverage) in the news. So you'll have to seek it out yourself or just wait until next week.

Math Ed in Colorado

I made it through a week with nobody asking me to post a new job opening, so I hope that means positions are filling and teachers are settling in and readying themselves for a new school year. If I hear anything new, I'll post it next week.

This Week in Math Ed: July 8, 2016

Math Ed Said

July 1: Mark Chubb starts us off this week with "Concept vs Procedure: An anecdote about what it means to be good at math." I highly recommend this post, and am reminded that the entirety of the learning experiences and assessment opportunities we design for students matter, not just the formal demonstrations of formalized algorithms.

July 2: This October 2015 article from Eric Westervelt on the KQED Mindshift blog describes "How Adding Math to a Child's Home Routine Can Advance Achievement."

Shared by: Steph Gunning, Karyn Vogel, Alayne Armstrong, Kristin Frang, Gary A. Petko, Julie Wright, Jennifer Bell

July 3: From the Farnam Street blog, people (re)shared "Richard Feynman on Teaching Math to Kids and the Lessons of Knowledge." A post like this makes me glad the standard for mathematical practice is "attend to precision," not "be (a certain kind of) precise." Feynman had some good examples where curriculum materials in math and science stressed certain points or used certain language in the name of precision, but arguably did little to further student understanding.

Fireworks, Desmos style
July 4: It's a holiday in the U.S. You bring the math, and let Desmos set off...Fireworks!

Shared by: Desmos.com, Martin Joyce, Ron King, George Carganilla, Mr. Keller, TODOS

July 5: The title of this post speaks for itself: "Math, Desmos, and Artglass Windows." It's great to see some uses of Desmos beyond the classroom.

July 6: Dan Meyer has a new blog series going, the latest of which is the post "Who Wore It Best: Maximizing Area." Two things I really, really like here: (1) I get to see three math ed technologies used side-by-side, which helps me understand the capabilities of each, and (2) Dan is putting the math first, and letting technology serve the math. That's hard to do with technology, as products are often presented as solutions in search of a problem.

Math Ed in the News

Comment: The last of the above articles, written by Ben Christopher and originally appearing on Priceonomics, is probably the single best take I've seen on the issue of accelerating students through (or past) middle school mathematics classes. In particular, this article makes it clear that 8th grade math, as described by the 8th grade standards, largely is what parents remember as "Algebra 1" from when they were in school. SFUSD's work with the SERP Institute and mathematics course pathways comes through loud and clear here, and I look forward to seeing new data come in as fewer students are skipping through the curriculum on a rush to Algebra 1 and beyond.

This Week in Math Ed: July 1, 2016

Welcome to the 26th TWiME, marking the half-way point of 2016! I'm posting this a week behind my hoped-for schedule, so to catch up I'll abbreviate this TWiME to be just "Math Ed Said." The rest of the usual bits can wait for the next post.

Math Ed Said

June 24: Everyone was talking about Brexit, including math teachers. They shared the Washington Post story, "The British are frantically Googling what the E.U. is, hours after voting to leave it," highlighting some of the post-vote confusion and uncertainty.

Shared by: Robin Mathews, Markus Sgbi, Julie Reulbach, Janice Cotcher, Matt Owen, Keith Devlin

June 25: A number of stories were shared by four people each, but I'll choose @druin's: "Making Thinking Visible - Chapter 1."

Shared by: Druin, Mary Dooms, Bridget Dunbar, Pam J. Wilson

June 26: Four people shared a geometry problem on Solve My Maths involving the fraction of an octagon occupied by a center square.

Shared by: solve my maths, Jamie Duncan, Amie Albrecht, John Golden

June 27: While a number of people were already talking about Tau Day (see June 28th below), Sara VanDerWerf's post, "Secondary Number Talks (I’ll convince you with ducks)" was popular on the 27th. High school teachers are prone to complain about the lack of arithmetic fluency, and Sara suggests we re-evaluate our claims of not having enough time to build that fluency with some strategically placed number talks.

Diane Briars and Matt Larson at NCTM 2016
June 29: People can't seem to resist jumping to conclusions when it comes to international assessments and the data they produce. Recently, an OECD report about the PISA led some to speculate that curriculum should emphasize pure math over applied math. Not so fast, says NCTM president Matt Larson, who urges us to "Read Beyond the Headlines." The 200+ page OECD report mentions a number of strategies to help expand opportunities for all students to learn mathematics, including building upon coherent standards, reducing the impacts of tracking, and learning to teach heterogeneous classes of students.

June 30: "The Problem with Story Problems" by Anita Bright in Rethinking Schools is likely to challenge you with its examples of bias, privilege, normativity we typically see in math word problems. It's easy for me to read something like this and think, "Okay, yes, I agree, go on...now really, you're taking issue with wallpaper?" I have to remind myself that this article isn't about the wallpaper or any other particular example, and I'd be foolish to be derailed by such a detail. Focus on the bigger picture: the worldly contexts in which we mathematize are part of the student experience, and context deserves our scrutiny because it reflects our assumptions and values.

From the better-late-than-never department: It took me parts of four different days to finally put this together, but here's TWiME for the seven days beginning June 17.

Math Ed Said

Matt Larson at the 2016 NCTM Annual Meeting
June 17: NCTM President Matt Larson blogged about his vision for NCTM. As I've said before, I'm pleasantly surprised at how NCTM has moved in the past couple of years to be more open, responsive, and innovative. Matt Larson's vision echoes some thoughts of my own, but as I went to the comment section, my critique now turns to the online math ed community: Three comments? That's it? Two of the comments I'm pretty sure belong to past NCTM presidents Michael Shaughnessy and Johnny Lott, which leaves only one from a teacher. I'm writing this more than 10 days after Larson published the post, and while there was enough Twitter activity to make this the most-shared thing on the 17th, the lack of comments troubles me. And since I'm amongst the non-commenters, I'm as guilty as the rest. I may have to change that. Will you?

June 18: Mike Lawler showed us "A fun way to estimate e with kids." I don't find much of anything with e and natural logs to feel natural at all, so I watched all three videos with interest.

June 19: A nice thing about writing versus talking is that when I want to salute the U.K. for something good, I can just use a word or phrase without attempting the accent. Here's Hannah Fry with a cracking interview in The Guardian, "There's a mathematical angle to almost anything."

June 23: An interesting outcome of the Fordham survey described in Education Week is that, on average, teachers seem to say some things that might seem contradictory. Here, they say there is a higher priority on computation, yet memorization is down. Similarly, when Choppin, Davis, Drake, and McDuffie (2013) surveyed middle school math teachers about Common Core, in which some teachers said Common Core requires them to teach more conceptually and more procedurally. Results like these are a good reminder that survey responses sometimes have to be taken with a grain of salt.

Around the Math Ed Web

You can check out the recording of Sara Van Der Werf's Global Math Department presentation, "The Pursuit of 100% Engagement: Practical ideas to get you closer." It doesn't appear there was a new presentation tonight, and I don't see one for next week, yet, but you can check the GMD website to see when the next one is announced.

Otherwise, the math ed web seems pretty quiet. I think either teachers are taking a well-earned break, or they're too busy at conferences or in PD to be doing as much online.
