This project builds on prior efforts with learning progressions, and is focused on key carbon-transforming processes in socio-ecological systems at multiple scales, including cellular and organismal metabolism, ecosystem energetics and carbon cycling, carbon sequestration, and combustion of fossil fuels. The primary project outcomes will be coordinated instructional tools that are useful to professionals at all levels in the science education system--classroom teachers, professional developers, and developers of curricula, standards and assessments.

This collaborative project is developing instruments to assess secondary teachers' Mathematical Habits of Mind (MHoM). These habits bring parsimony, focus, and coherence to teachers' mathematical thinking and, in turn, to their work with students. This work fits into a larger research agenda with the ultimate goal of understanding the connections between secondary teachers' mathematical knowledge for teaching and secondary students' mathematical understanding and achievement.

This project is studying measurement practices from pre-K to Grade 8, as a coordination of the STEM disciplines of mathematics and science. This research project tests, revises and extends learning trajectories for children's knowledge of geometric measurement across a ten-year span of human development. The goal will be to validate all components of each learning trajectory, goal, developmental progression, and instruction tasks, as well as revising each LT to reflect the outcomes of the experiments.

This study addresses the question: Does gaining admission to a selective STEM specialty school improve students' academic success on the SAT, SAT II, and Advanced Placement exams? Other portions of the investigation follow additional student outcomes, including: participation and success in STEM competitions; STEM publications; intentions for postsecondary STEM education and STEM careers; and initial postsecondary STEM education. This study seeks to inform considerations of the cost/benefit of directing resources to support such schools.

In this project, investigators are laying the foundation for a rigorous quasi-experiment to test the effects of attending such a school using longitudinal student records, surveys, and interviews. By documenting survey response rates, student location rates, and rates for successful matching of student administrative and survey data, this project is demonstrating that it is possible to collect data that would enable a large-scale study to be launched with the necessary instruments and experience in hand.

The new ViSTA Plus study explores implementation of a program for pre-service/beginning teachers that is fully centered on learning from an analysis-of-practice perspective, addressing the central research question of "What is the value of a videocase-based, analysis-of-practice approach to elementary science teacher preparation?" The project is producing science-specific, analysis-of-practice materials to support the professional development of teacher educators and professional development leaders using the ViSTA Plus program at universities and in district-based induction programs.
