This Week in Math Ed: March 11, 2016

Math Ed Said

March 4: Graham Fletcher is back with another video in his Making Sense Series, "The Progression of Addition and Subtraction." Perhaps my favorite thing about these videos is that my perspective of standards more easily shifts to a multi-year span of time, instead of a deadline when those standards appear for a particular grade. Learning takes time, y'all.

March 5: Corey Drake's article, "The fantastic new ways to teach math that most schools aren’t even using," was the most-shared link on March 3rd and it topped the chart again on the 5th.

This is my one picture of Dan Meyer, and it's lousy. It's him, trust me.
March 6: Dan Meyer's advice to his younger self and other teachers is to "Ignore The Adjectives. Watch The Verbs.." I hadn't quite thought of this the same way, but I've come to cringe when I hear "hands-on" and "real-world," as both terms have been overused and abused of their meaning. Instead, I find myself asking, "What are students mathematizing?" This is where it's particularly helpful for me to think about Adrian Treffer's classic Three Dimensions, in which he describes horizontal mathematization is described as starting from a realistic context and organizing it mathematically with increasingly sophisticated models, while vertical mathematization is described as a process of reorganizing within the mathematics itself.

March 7: Ilana Horn wrote "Professional Development is Broken, but Be Careful How We Fix It." Not only is the post great, but the comment section is equally great! Posts like this really hit home for me, as I'm now in a position where I'm tasked with bringing outside expertise to a group of teachers. My years in academia have sensitized me to labels, definitions, and frameworks, and there's a challenge to interpret people's discourse and ideas with each new group I meet with.

March 8: A post on the Achieve the Core website, "Mathematical Knowledge for Teaching," highlights the special kind of knowledge math teachers need for choosing problems and methods that best set the conditions for student learning. This math teacher knowledge is often called "Mathematical Knowledge for Teaching," which may be best known for being described in Ball, Thames, and Phelps (2008).

March 9: NCTM and Teaching Children Mathematics (TCM) held another #TCMchat, this time around Chepina Rumsey's article, "Promoting Mathematical Argumentation."

March 10: Robert Kaplinsky asks a question near and dear to me, "Why Are You Using That Problem?" I don't think I would have answered the same way Robert has, but I appreciate efforts to articulate the criteria with which problems/tasks/activities are chosen.

Around the Math Ed Web

NCTM had a March 1 deadline for APME chapters (and as of this writing this page still says March 1), but according to a tweet, it appears the deadline has been extended to March 21.

I haven't been saying enough about the Principles to Actions book chat (#nctmp2a), which continues on across a series of tweets and blog posts. I see so much good stuff in Principles to Actions and have sometimes wondered if there shouldn't be some kind of 8-year PD plan for the 8 teaching practices it describes. I think you could dig deep that entire time and still not max out your teaching abilities.

"Using Peer Feedback to Increase Student Understanding" was the topic at this week's meeting of the Global Math Department, and next week's presentation is slated to be "Bringing the World Outside School Into Your Math Classroom."

Research Notes

Another article has been added to the June 2016 issue of The Journal of Mathematical Behavior:
And that's it. Maybe this will give me a chance to catch up with last week's giant list of new research articles.
