Come hang out with me at California Math Council’s North and South conferences in November and December.

CMC-South. Palm Springs, CA. November 15-16. I’m going to describe how “rich tasks” and “bland tasks” both fail our students. And I’m going to do it with 15 students on a stage in a live lesson demonstration. Let’s gooo! [register]

CMC-North. Pacific Grove, CA. December 6-8. I’ll share some of the ways my colleagues and I at Desmos are designing for belonging in math class, specifically how we try to expand the list of who counts as a mathematician and what counts as mathematics. [register]

It’s my annual tradition to scrape all the handouts and slides from the NCTM annual conference website and put them in a more usable form and location, including a single, massive download link [2.8 GB].

But this year I also found recordings from every session.

Not video, nope.

Twitter!

People were recording the sessions on Twitter. People were in sessions the entire conference tweeting key findings, memorable phrases, and impactful slides.

Those tweets were enjoyed in the moment by people who were near their computer during the session. But every session’s tweets were mixed up with every other session’s tweets from that same time period. Then they were lost immediately afterwards to a timeline that doesn’t stop moving.

So I re-captured those tweets and attached them to every talk.

I wrote a script that copied every speaker’s Twitter handle and the time of their session from the program book. Then the script searched Twitter for their handle and “#NCTMSD2019” and — here’s the thing! — captured the results only from the time period of their session. Not during their flight to NCTM. Not during the fantastic happy hour after their session either.

So at this site you’ll see the usual listing of speakers and sessions — but you’ll also see columns that let you know a) how many attachments those speakers made available and b) how much Twitter coverage their sessions received.

Here’s why this is a blast. Lauren Baucom gave a dynamite talk describing her work supporting the de-tracking of her high school. No handouts or video, but here are 34 tweets to help you connect with her ideas. The same is true for loads of other presenters.

I think a lot about Jere Confrey’s statement that “students are the most underutilized resource in our schools.” Students bring value to our classes — their identities, their aspirations, their early and developing understandings of mathematical ideas — that too often goes uncelebrated, unexplored, and underutilized.

Similarly, thousands of teachers traveled at great length and great expense to San Diego last week. Thousands of brains, bodies, and souls all together in community. What did we make of that experience? What do we have to show for it? Here’s one thing and I’d like to know more.

I’m on a shortened schedule at NCTM this year but I’m making the most of it. Here’s where you’ll find me.

Thursday

How to Present at NCTM

Robert Kaplinsky and I would like to help you propose a session and and present it at NCTM. Robert has served on the NCTM program committee and will help you understand how proposals are evaluated. I’ve presented professionally for nearly a decade and will offer my own playbook for designing and delivering presentations. Our motives are selfish. So many of you have stories to tell and insights to offer. Our profession needs them out of your head and into all of ours.

The Desmos Booth

Stop by the exhibit hall and say hi sometime between 3PM – 4PM. Tell me what you’re working on.

ShadowCon v3.0

For the last two years, ShadowCon has functioned as a sort of research and development arm of NCTM’s program committee. Zak Champagne, Mike Flynn, and I study an idea on a small scale (filming every presentation, for example, or giving every presenter a webpage for follow-up discussion) and NCTM uses our data to decide if they should expand the idea to more presenters. This year, we have four exceptional presenters — Cathy Yenca, Anurupa Ganguly, Kassia Omohundro Wedekind, Geoff Krall — offering provocative ideas and we’ll study a new template for conference follow-up.

Friday

Desmos Happy Hour

Even before I worked at Desmos, this was my favorite happy hour. Great energy. Great people from all across NCTM’s membership. Come for a free drink. Stay for the math trivia. Doors open at 7PM. Trivia starts at 8PM.

Saturday

Math is Power, not Punishment

This is the last time I’ll give this talk, the accumulation of a lot of thinking and designing around Guershon Harel’s concept of “intellectual need.” I’ll start by pointing out that the software engineers at Desmos and the summer school Algebra II students I worked with in Berkeley had very different answers to the question, “What would your life be like without variables?” Then we’ll figure out how to bridge those answers.

There is a 95% chance that each of my sessions will be filmed. I mention that in case you can’t make the trip to San Antonio and also because, even if you can make the trip, there are lots of amazing sessions in each time slot.

In the comments, let us know what you’re excited to do and see at NCTM.

BTW. If you’re feeling even a little bit intimidated by the deluge of people and ideas at conferences like NCTM, I recommend you read Nic Petty’s 10 hints to make the most of teaching and academic conferences.

Bonus. In an example of the creative forces that can flow through tweeting and blogging communities of practice like this one, Meredith Thompson commented on my last post that:

… looking at climate change over a short period of time gives one picture, but enlarging the frame to geological scale shows great fluctuations in temperature. This argument becomes “fuel” for people who claim that global warming is not a problem — yet the current dramatic increase (sometimes called the hockey stick) convinces many people (myself included) that action is needed.

This seemed like a job for a Desmos activity. Here is one where students crop climate data in two different ways, using those selections to make two opposite claims about the data, experiencing firsthand how easy it is to distort data.

Disclaimer

I doubt I’m NCTM’s median or ideal member. Accommodating all my wishes below might be a great way to doom the organization. That said, my wishes are the only ones I have. So make yours known too.

The Promise

NCTM membership promises lots of benefits, but chief among them in my mind are advocacy, professional development, and community. Here are some thoughts about NCTM’s present work in each of those three categories and some hopes for its future.

Advocacy

In the era of the Common Core State Standards, math education is a matter of national and local interest. Nationally, witness Andrew Hacker’s op eds in the New York Times. Locally, witness your Facebook timeline and all the parents complaining about lousy “Common Core” worksheets. (“What do you mean the Common Core didn’t make this worksheet? It says it’s theirs right in the link!“)

At a time when everybody seems to have an opinion or a comment, it’s really hard for me to locate NCTM’s opinion or comment.

There were three years between the release of the final Common Core State Standards and NCTM’s statement announcing its support. Borrowing from Twain, lies about the array model can travel halfway around the world when NCTM takes three years to put on its shoes.

Or try to find NCTM’s advocacy more recently. By my count, The Atlantic has published six articles about math education since December. NCTM is quoted in none of them. Am I expecting too much? Do these reporters even have NCTM’s number in Reston, VA? I throw my dues into the collection plate so that, collectively, math teachers can have a louder megaphone than any one of us would have individually.

Professional Development

I experience NCTM’s professional development efforts through its journals and its conferences. Let’s talk about each.

I’ve had the latest issue of Mathematics Teacher in my backpack for the last three weeks. I’m trying to figure out why it doesn’t seem like urgent reading to me whereas there are about twenty math education bloggers in my feed whose posts will not wait and must be read immediately. I’m also wondering why I give JRME, NCTM’s academic journal, a lot more scrutiny relative to the teaching journals.

Here’s my idea. The teaching journals lack the kinetic energy of JRME and they lack the potential energy of blogs.

By “energy” I mean that the energy of a piece of writing is partly kinetic — what the author actually wrote — but also potential. Given the right forum, readers will come alongside those words, offer their own, and co-construct incredible kinetic energy out of that potential.

JRME articles have low potential energy but incredible kinetic energy. Responses to articles are only published after months or years but the articles themselves and their ideas are often very well-researched and very well-written. Articles in the teaching journals have lower kinetic energy than JRME articles (because it’s much harder to publish in JRME) and their potential energy is … also pretty low. For example, Albert Goetz’s response to my modeling article appeared 11 months after the original publication. That latency won’t allow us to convert the potential energy of my article into anything kinetic.

So the teaching journals are stuck somewhere in the middle. I don’t know if this is cause or effect, but no one has tweeted out a link to any article from any of the teaching journals. None of them. Ever. [2016 Apr 27. This is too strong. Here’s a tweet. I’m not clear why it isn’t returned in Twitter’s search results. I think my general point about the low potential energy of the teaching journals holds.]

Short of taking down the paywalls, I don’t have a great idea for increasing the potential energy of the teaching journals. My colleagues Zak Champagne, Mike Flynn, and I have put in a great deal of thought trying to increase the potential energy of the conferences, though. For two years now, NCTM’s leadership has given us some room to play around with the very simple idea of giving every speaker a webpage for their conference session and then getting out of their way. Relative to dropping the paywall on the teaching journals, this is a very cheap idea.

And it seems successful also. They gave a small handful of speakers webpages this year. A week after NCTM’s annual meeting, there are 135 comments, all turning potential energy into kinetic energy without any marginal effort from NCTM. (Check out the energy at Kaneka Turner’s page for example. We haven’t even released video of her talk yet!) That system will scale. NCTM needs to make that system available to every speaker and they need to add the question to their speaker application form, “How will you help your attendees convert your ideas from potential energy to kinetic energy?” (Or something more appropriate for people who haven’t read this post. “How will you support your participants’ work after the conference?” maybe.)

Community

Here is an area where my intuition totally failed me. My assumption was that math teachers who have found community online for free are less interested in paying money to find community in some distant city at an annual or regional meeting.

I was way wrong.

Feel free to scroll through the comments and read person after person describing how much more interested they are in attending a national conference knowing their online community will be there also.

NCTM needs to do everything they can to import and export that community.

They can import that community by making sure we’re all aware who the first time presenters are so veterans can attend their talks, support them, and also benefit from their perspectives. They can import that community by helping these unwashed bloggers and tweeps find their way to longstanding NCTM functions and events. And vice versa, by exporting themselves to blogging and tweeting events like ShadowCon, the Desmos Happy Hour, and Math Game Night. (Matt Larson checked me for not passing him an invite to the Desmos Happy Hour. That’s fair. This obligation goes both ways.)

NCTM can support these blogging and tweeting attendees after the conferences by giving them lots to blog and tweet about. Feed the community. It seems no one is tweeting about the teaching journals. But lots of people are tweeting about the release of the videos from the Ignite and ShadowCon talks. Jo Boaler’s talk was at capacity with a thousand people locked outside. You wouldn’t know from her conference listing that someone captured video of that talk. No one knows where to find it so no one is talking about it.

Fix that! Give every speaker a webpage. Help them understand how to turn its potential energy into kinetic energy, how to turn isolation into community.

Spoiled

Again, I imagine my needs are pretty idiosyncratic. I’ve been spoiled by blogging and tweeting and by the teaching community that lives on my phone and travels with me in my pocket wherever I go. So what are your professional needs? How well has NCTM been servicing them? What hopes do you have for its future?

Featured Comments

Please read NCTM President Matt Larson’s response to my post. His description of NCTM’s advocacy efforts was particularly useful.

Also read NCTM Past President Linda Gojak’s comment.

Kim Morrow-Leong:

Is the role of NCTM to be the leader of the frenetic #MTBoS blogosphere? Or is it to be the slow, more “craft beer” or “fine wine” place for ideas to ferment? What is the in between? Make your suggestions known because it is hard to be both.

Zak Champagne:

The editorial board of TCM (full disclosure — which includes me) is working hard to create some kinetic energy around the journal. We are hold a #TCMChat each month on twitter around the free preview manuscript (Which coincidentally means we tweet the heck out of link to the free preview every month).

Megan Schmidt:

Early Friday morning of NCTM, I attended a focus group to discuss the future of NCTM and more specifically, their partnership with the Math Forum. Many issues were discussed including the ones you bring up here. But one that seemed to resonate with everyone in attendance was the people who work for the Math Forum. Joining the Math Forum and NCTM has given NCTM a face and a personality exemplified through the wonderful people that make up the Math Forum. They have helped bridge the divide, physically and metaphorically, between NCTM and the greater Math Twitter Blogosphere and have been a catalyst for the continuing conversation between these groups.

Sam Otten:

I have (what I think is) a really great linear systems lesson that I developed with my brother. It’s been accepted for publication in MT but it’s going to be about a two year gap between submission and publication.

Sam Shah posts his internal monolog every time he imagines inviting a teacher to submit an article to the teaching journals versus posting it on a blog. He closes with:

But for me as a part of a community which already shares ideas freely, comments on them, improves them… I don’t see how an NCTM journal can compare. Immediacy, feedback, and encouragement make blogging the choice for me.

Mary calls out her interest in extending the conversation in several sessions she attended. NCTM can support this.

There were several K-2 talks I attended at NTCM that I would love “to continue the conversation.” I tried Twitter, but the sessions had low turnout so there was no interaction. One was ELD and math, giving students position and power. They used Go Pros to observe from a child’s perspective and introduce change to their teaching. It was awesome; every k-2 teacher should have been there and needs to think about how we are giving voice and power to our students.

Norma:

In regard to Advocacy, it isn’t all invisible. Check out http://www.nctm.org/news/ for NCTM press releases as well links to press coverage (with quotes from NCTM Presidents).
