Assessment for the Common Core Mathematics Standards

open access: yesJournal of Mathematics Education at Teachers College, 2012
This article makes two simple observations about high-stakes assessments. The first is that, because mathematics is a very technical subject, an assessment item can be mathematically flawed regardless of how elementary it is.

Modeling in the Common Core State Standards

open access: yesJournal of Mathematics Education at Teachers College, 2011
The inclusion of modeling and applications into the mathematics curriculum has proven to be a challenging task over the last fifty years. The Common Core State Standards (CCSS) has made mathematical modeling both one of its Standards for Mathematical ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Is Common Core “Working”? And Where Does Common Core Research Go From Here?

open access: yesAERA Open, 2017
Five years into the Common Core initiative, researchers and the general public are interested to know whether and how the standards are “working.” In this introduction to the special topic, I discuss the state of the literature on these questions and ...

Quantitative Literacy and the Common Core State Standards in Mathematics

open access: yesNumeracy, 2015
How supportive of quantitative literacy (QL) are the Common Core State Standards in Mathematics (CCSSM)? The answer is tentative and conditional. There are some QL-supportive features including a strong probability and statistics strand in grade 6 ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Common to the Core States: How Solid Is the Mathematics Core in Each State? [PDF]

open access: yesNonpartisan Education Review, 2018
The final draft of the Common Core State Standards (CCSS) was released in June 2010 by the National Governors Association (NGA) and the Council of Chief State School Officers (CCSSO).1 The NGA reports that 45 states had adopted the CCSS by June 2012.2 ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
