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, promote, or improve the work.

Chapter in Mathematics Teachers at Work: Connecting Curriculum Materials and Classroom Instruction.

This book compiles and synthesizes existing research on teachers’ use of mathematics curriculum materials and the impact of curriculum materials on teaching and teachers, with a particular emphasis on – but not restricted to – those materials developed in the 1990s in response to the NCTM’s Principles and Standards for School Mathematics.

To investigate the contribution of the DR K‐12 portfolio to the knowledge base on math and sciencelearning among ELLs, CADRE designed a study to explore the ELL work that is being conducted in theDR K‐12 projects. This paper summarizes the work of this study. It begins with a description of themethodology employed, followed by a presentation of the findings, and finally a discussion of theconclusions drawn from this work.

Heat transfer is widely taught in secondary Earth science and physics. Researchers have identified many misconceptions related to heat and temperature. These misconceptions primarily stem from hunches developed in everyday life (though the confusions in terminology often worsen them). Interactive computer simulations that visualize thermal energy, temperature distribution, and heat transfer may provide a straightforward method for teaching and learning these concepts.

This paper reports preliminary results from an investigation, still in progress, on the use of verbal protocols among native Spanish-speaking, English language learners (ELLs) of various proficiency levels and background characteristics. We focus on language use among ELLs during various stages of a cognitive interview designed to probe whether and how students
