@stanyoshinobu Second, in this series, we take a close look at the work involved in "weeding out." I think these pieces can help us complicate the narrative that changing "weed out culture" is simply a technocratic fix.

@stanyoshinobu Thank you for this thread and resources! May I humbly add a couple more?
First, this one is *hot off the press,* (even though I've been working on it for years...)
"Towards anti-deficit education in undergraduate mathematics education"

@riehlt Congratulations Tony! This is bittersweet. Your impact in MT is massive, we have #thinkingclassrooms across the state. My classes look very different thanks to you and your colleagues’ efforts. The important question is, will you still be hosting @MCTMmath trivia nights?
@pwharris Partitive interpretation: It took me 4.1 minutes to walk 1/5 of a mile. What is my average rate, in minutes per mile?
I can answer this by fining how long it would take to walk 1 mile (at this rate)
I have 1/5 of a mile so I need to multiply by 5.
4.1 x 5 = 20.5
I appreciate the commercials, the yelling, and other noisy ways of recognizing the dignity of blue collar work (our heroes!). The recognition is long overdue. Now let’s insist that these jobs have benefits and compensation that reflect the dignity of the work.
Kudos to the #UMassEDUC faculty members selected as @AERA_EdResearch Outstanding Reviewers for 2019: @SciEdHenry for the American Educational Research Journal, and Scott Monroe for the Journal of Educational & Behavioral Statistics. Read more here: https://t.co/IO4KbeRiRc
"Can the global economy survive without non-stop production and non-stop consumption? It seems the flora and fauna can. Perhaps we can too, and emerge out of this crisis of planetary proportions as a better more humane species."

@pwharris If we count in tenths, we have:
216*9
=216*(10-1)
=2160 - 216
=1944
Now, the units are tenths*tenths = hundredths
So: 1944 hundredths.
(Or 19.44 in decimal notation)
@EulersNephew @MathTechCoach @abel_jennifer@alittlestats Ditto. I love this book.
FYI, Eric Stade at @CUBoulder has a revised version of the book, which he produced for his course, “calculus, systems, and modeling” (now called calc for life sciences).

@pwharris@KarenCampe@adinam225@ctfosnot Cool! The problem strings are one at a time, with conversation in between. In general for a problem string it wouldn’t be on paper at all, but in this case the physical layout and room to write is important, as we described in the paper.
@KarenCampe@adinam225@pwharris@ctfosnot You bet! I hope it's helpful. The relationship between fractions and division underlies so much of how fractions are used in algebra.The activity sequence sets the stage for understanding the "division step" in an equation, and for understanding slope as a rate of change.
@KarenCampe@adinam225@pwharris@ctfosnot We did a study on teaching fracts & ÷ meaningfully to high school students (who generally only knew this as a rule), using the sub sand problem. We developed an activity seq. based on the study.

@pwharris The answer is 504/24, a perfectly good number in fraction form.
To write it in decimal notation, my strategy is to decompose 504 into chunks that are divisible by 24. The most obvious chuck is 240, so I'll start with that...
504/24 = (240 + 240 + 24) / 24 = 10 + 10 + 1 = 21
@MandyMathEd@Dawilli6@megawicks1 The goal is not just to produce better mathematics, but also to produce a common world, and to take up space in that world with courage, humility, and empathy.
