Ryan gives the best 2 sentence summary of the NCTM's 8 effective teaching practices I've ever seen. drive.google.com/file/d/1SRkb...
Colorado only requires 160 days for districts with 5-day school weeks, but for districts with 4-day weeks (about 133 of our 178 districts), then can have even fewer so long as the instructional hours add up. The last district I taught for only had 144 instructional days. www.cpr.org/2025/03/31/w...
I saw presentations at AERA that did math textbook analysis and it made me wish that we had information that went far beyond what we get from EdReports. Pacing data would be useful, as would percentages of problems rated by cognitive demand and the use of verbal, visual, and contextual features.
I've seen this before and it's still so weird to me that it got published in a Journal of Medicine.
Some good news for this Friday. This astonishing group of people have spun up ERICA, the ERIC archive. www.datarescueproject.org/erica-to-the...

I browsed the #AERA2025 exhibit hall and saw a lot of books that I want. My question becomes: How many more books can I pile on to my shelves before I trigger a structural collapse of the floor? There's a number. I don't know what it is, and I hope it's pretty big, but there's a number.
Anyway, crazy times. The mission of helping people learn math more deeply and powerfully seems, if anything, more important than ever.
Maybe when you're done with the LOC, you can head to Rutgers next to dig into their archives. 😉 archives.libraries.rutgers.edu/repositories...
Just had the prep call for the opening panel (on using math to improve the world) at @JustEquations free, virtual conference, The Mathematics of Opportunity. It's going to be great! Join the fun - ensuring that math education expands opportunity for students.

I think this article might be up your alley. Check out the six RME principles of teaching mathematics by van den Heuvel-Panhuizen and Wijers: drive.google.com/file/d/1h19l...
I occasionally think I want to write a book focused on these things, but for now, Marja's article will have to do.
Also noteworthy: I had four consecutive quarters making satisfactory progress for keeping objects out of my mouth.
Kindergartners have lots of stuff to learn.
A report card with the handwritten comment, "Raymond has good ideas and solutions to problems."
We were talking about our old report cards this morning in the office so I decided to dig mine out. I had one comment from my Kindergarten teacher, Mrs. Reingardt, and honestly it might be all I've ever wanted people to say about me.
"Raymond has good ideas and solutions to problems."
This strikes me as well-said: "Situations that call for immediate response are very frustrating to children who have no thought processes available that permit them to answer in the time allotted."
I like that this isn't about anxiety, which sounds medical. It's about balancing skill vs. time.

Reading Rathmell (1978) with fresh eyes while participating in a book study of Bay-Williams and SanGiovanni's Figuring Out Fluency. I like this advice regarding drill: It's needed to develop immediate recall, but make sure you're drilling _efficient_ strategies, not inefficient ones. #MTBoS #mathed

On Twitter, I had built up a list of almost 5,000 people who posted pretty reliably about #matheducation. Here's my attempt to start the same kind of list here. I believe you can follow it and pin it to the top of your timeline:

This sounds a lot like Sfard (1991) -- if you haven't read it, I think you'll like it.
Sfard, A. (1991). On the dual nature of mathematical conceptions: Reflections on processes and objects as different sides of the same coin. Educational Studies in Mathematics, 22, 1–36. doi.org/10.1007/BF00...
Allow me to paraphrase the quoted statement for the irony:
"I am convinced of what I have learned--not because someone explicitly told me in an article--but because I've been given opportunities to experiment in my own practice, make observations, and synthesize conclusions that make sense to me."
"Knowing from Memory" =/= Memorization.
This is definitely a call-back to Aldous Huxley's "Brave New World' and the introduction of hypnopaedia : ecampusontario.pressbooks.pub/englishliter...

I wish I could be there! I'm sure I've heard parts of it already, but most of those books are new to me and I'm quite interested in what you found in them.
