Increases can increase! We created "filling area" animations, in which students could explore changes in length and area. How students conceived of the "things" that were changing linked to their notions of increasing increases. https://t.co/vWPfkQBpo9 #op
Graphs and charts are everywhere these days. How can students make sense of "increasing increases"? Re-sharing an article we wrote in 2018. https://t.co/vWPfkQBpo9 #openaccess #mathed #MTBoS
@KentHaines @mpershan You might have to refine how you look. Local theories can build on grand theories, such as Piaget's constructivist theory. You won't find Piaget if you search our #openaccess article, but Thompson's theory builds from it. https://t.co
It matters who our research participants are. Our students are experts in their math reasoning. As researchers, we learn from them. https://t.co/vWPfkQBpo9 #openaccess #MathEd cc @bzahnersdsu

Submitted earlier versions of this paper to present at conferences. Rejected. Twice. First version of this paper got a "Reject, with encouragement to resubmit" Now it's published in one of the best journals in the field. https://t.co/MGMzNq9p8s #AcWri #Aca
@siwelwerd My favorite publications are ones that have been through the fieriest flames. This new one that just came out received a "Reject and Resubmit" in the first round. https://t.co/Gli7Yrpbuv
Want to help students reason about "slow" or "fast" growth? We have research based recommendations in our new article- https://t.co/XS1BgDtYyA #MTBoS #iteachmath https://t.co/GpKLAy8c89
We have a new article, @DavidKButlerUoA We discuss conditions fostering students' discernment of variation in change that occurs in a single direction. Or - how can middle school Ss come to think of an "increase" or "decrease" as something that can vary?
Wonder how to help middle school students make sense of statements like the one below? Check out our new article. https://t.co/8paENOr5Sb #openaccess #MTBoS https://t.co/tWwk5w4sk5
In our new article, we share recommendations for designing tasks to provide students opportunities to make sense of variation in change. https://t.co/r4rjqXlskq cc @davidwees #openaccess #maths #mathed
