Resource | Professional Noticing of Children’s Mathematical Thinking
The construct professional noticing of children’s mathematical thinking is introduced as a way to begin to unpack the in-the-moment decision making that is foundational to the complex view of teaching endorsed in national reform documents. We define this expertise as a set of interrelated skills including (a) attending to children’s strategies, (b) interpreting children’s understandings, and (c)…

Resource | Preparation and Characterization of a Monolithic Column for use in HPLC: An Undergraduate Laboratory Experiment
The high-performance liquid chromatography (HPLC) experiment, most often done in the undergraduate analytical instrumentation laboratory course, generally illustrates reversed-phase chromatography using a commercial C18 silica column. To avoid the expense of periodic column replacement and introduce a choice of columns with different stationary phases, we have developed an experiment in which…

Resource | Networks and Social Media for STEM Educators, Policymakers, and Researchers
In this pdf are STEM education networks and social media sources that may be of interest to DR-K12 grantees for the purposes of (1) disseminating knowledge and products and (2) developing partnerships with stakeholders and end users. These networks and social media were chosen because they provide researchers and developers with an opportunity to present their work to individuals that could use,…

Resource | Negotiating Identities for Mathematics Teaching in the Context of Professional Development
In this article, we present an analytical approach for documenting the identities for teaching that mathematics teachers negotiate as they participate in two or more communities that define high-quality teaching differently. Drawing on data from the first two years of a collaboration with a group of middle-school mathematics teachers, we focus on a critical initial condition for teachers to…
