Bookmarked Teaching After Twitter (

I am interested here as someone who realizes how much a) community, b) professional learning, and especially c) knowledge production arose from the particular context (including technological, political, personal, epidemiological, generational factors, etc) of 2005 to 2015. And I’m wondering where teachers–especially new teachers–will get that next.

With the changes to Twitter, Dan Meyer wonders where people might go to in order to engage with community now? He suggests that platforms like TikTok do not allow for the same level of engagement. This has me thinking about Dron and Anderson’s Teaching Crowds and Ian Guest’s research into Twitter. For Miguel Guhlin, the answer is Mastodon. He has published a number of posts to help with the transition.
Bookmarked The only question you need to ask about education technology. by Dan Meyer (Mathworlds)

My own rubric for evaluating edtech is very simple. One question tells me most of what I need to know.

What happens to wrong answers?

Dan Meyer discusses his simple rubric for evaluating edtech, “What happens to wrong answers?” He explains that “every wrong answer is a resource and we shouldn’t waste it.” The challenge is to value the student’s answer.

Meyer ends his post with a collection of others useful resources associated with reviewing technology, including a framework for thinking about technology centered in equity and Robert Talbert’s post re-considering points-based scoring.

Bookmarked Why Wordle Works, According to Desmos Lesson Developers by Dan Meyer (Mathworlds)

If you’re someone who designs learning experiences, I hope you’ll take Wordle as a challenge.

  • Can you create a wealth of learning opportunities with only a simple prompt?
  • Can you design the activity and support so that everyone learns as much from failure as success?
  • Can you offer feedback that goes beyond “right” and “wrong,” that helps learners identify everything right about their wrong answers?
  • Can you make room for multiple paths to correctness?
  • Can you offer learners a representation of their learning they can share with other people?
Approaching Wordle from the perspective of learning and teaching, Dan Meyer summarises five ingredients that have helped make it work so well.

  • Failure is expected.
  • Effective feedback.
  • Different routes to the same answer.
  • Your learning results in a product you can share.
  • It’s social

For a different perspective, Daniel Victor provides a profile of Josh Wardle and the meteoric rise of the once-a-day game. While as an alternative, sajadmh has created a version of Wordle in Google Sheets.

Bookmarked The #1 Most Requested Desmos Feature Right Now, and What We Could Do Instead by Dan Meyer (

We also want students to know that there are lots of interesting ways to be right in math class, and that wrong answers are useful for learning. That’s why we ask students to estimate, argue, notice, and wonder. It’s why we have built so many tools for facilitating conversations in math class. It’s also why we don’t generally give students immediate feedback that their answers are “right” or “wrong.” That kind of feedback often ends productive conversations before they begin.

Dan Meyer responds to the request that is often made for automated feedback, suggesting that such feedback is problematic.
Bookmarked “Real-World” Math Is Everywhere or It’s Nowhere by By Dan Meyer (dy/dan)

Amare is looking at these 16 parabolas. Her partner Geoff has chosen one and she has to figure out which one by asking yes-or-no questions. There are lots of details here. She’s trying to foc…

Dan Meyer on differentiating between ‘real’ models versus ‘non-real’ models in Mathematics. The problem with this is that from a process point of view it is all real learning.
Liked That Isn’t a Mistake by Dan Meyer (dy/dan)

It’s a bad mirror, so I call it a mistake. “Mistakes grow your brain,” I say. “We expect them, respect them, inspect them, and correct them here,” I say. And if we have to label student ideas “mistakes,” maybe those are good messages to attach to that label.

But the vast majority of the work we label “mistakes” is students doing exactly what they meant to do.

We just don’t understand what they meant to do.

Hi. I’m Dan Meyer. I taught high school math to students who didn’t like high school math. I have advocated for better math instruction here and on CNN, Good Morning America, Everyday With Rachel Ray, and I earned my doctorate from Stanford University in math education and I’m currently the Chief Academic Officer at Desmos where I explore the future of math, technology, and learning. I have worked with teachers internationally and in all fifty United States. I was named one of Tech & Learning’s 30 Leaders of the Future. I live in Oakland, CA.

I remember being introduced to Meyer’s work a few years ago. He takes problem based learning in Mathematics to a new level.
