Early science, technology, engineering, and mathematics (STEM) education sets the stage for future STEM learning. The purpose of this synthesis is to understand the findings from investments to improve prekindergarten (preK) and elementary science teaching from projects funded by the National Science Foundation’s Discovery Research PreK-12 (DRK-12) program. In the 5 years spanning 2011–15, the DRK-12 program funded or cofunded 25 projects, totaling more than $60 million, related to improving preK and elementary science teaching. Our review identified 25 DRK-12 projects related to improving preK and elementary science teaching funded in 2011–15. We synthesized findings from 25 of those projects that produced products (e.g., peer-reviewed journal articles, conference papers) that described the project and outcomes. We synthesized the empirical findings from interventions in four common areas of investment: (a) preservice preK and elementary preparation programs, (b) in-service teacher professional development (PD), (c) instructional materials for preK and elementary teachers, and (d) strategies for diverse learners.

The report summarizes the results from recent research and development projects that focused on modeling and simulations in science education. The Discovery Research PreK-12 (DRK-12) program of the National Science Foundation funded these projects as part of its mission to support the teaching and learning of science, technology, engineering, and mathematics (STEM) in grades PreK12 through innovative educational approaches.1 This report synthesizes findings from 33 articles produced by 18 DRK-12 grants awarded from 2011 to 2015, all of which funded development of resources or instructional practices to support student modeling in PreK-12 science education. This synthesis had two broad purposes: to describe 18 modeling-focused DRK-12 projects with respect to the resources they studied and the methods they used, and to summarize the new knowledge these projects produced related to modeling instruction.

Argumentation is a core disciplinary practice in mathematics and science that is important for both content understanding and everyday reasoning. In this report, we investigate how the National Science Foundation’s (NSF’s) recent research investments have advanced understanding and supported the development of interventions that improve the teaching and learning of argumentation in mathematics and science education. In the 5 years spanning 2011 to 2015, NSF’s Discovery Research PreK–12 (DRK-12) program funded or cofunded 23 projects relating to argumentation, with more than $40 million awarded. These 23 DRK-12 projects primarily focused on argumentation in high school and middle school and applied correlational/observational and longitudinal methods (rather than quasiexperimental or experimental methods), often reporting on the design and implementation of technological supports for the teaching and learning of argumentation. Our synthesis of empirical findings focused on how these projects studied both teacher- and student-facing interventions that improved the teaching and learning of argumentation, as well as naturalistic observations of argumentation in classroom settings that helped inform the design and development of future argumentation interventions.

Teachers’ pedagogical content knowledge (PCK) is a complex, multifaceted construct that is widely seen as foundational to the act of teaching. In this synthesis, we investigated how the National Science Foundation’s (NSF’s) recent research investments have advanced understanding and supported the development of teachers’ PCK in PK–12 mathematics and science education. In the 5 years from 2011 to 2015, NSF’s Discovery Research PK–12 program (DRK-12) funded or cofunded 27 projects relating to PCK, totaling $62 million awarded. These 27 DRK-12 projects primarily applied correlational/observational and longitudinal methods (rather than quasi-experimental or experimental methods), often targeting teaching in the middle school grades. Our synthesis of empirical findings focused on how these projects studied PCK, including its measurement, development, and relationship to teaching and student learning.
