DRK-12 Research and Products
Publication | Quality early science education is important for addressing the low science achievement, compared to international peers, of elementary students in the United States. Teachers’ beliefs about their skills in a content area, that is, their content…
Publication | This tool is designed for early career STEM education researchers to offer tips for building professional networks. The advice largely comes from National Science Foundation-funded awardees and early career researchers and developers who have…
Publication | Three 18-session design experiments were conducted, each with 6–9 7th and 8th grade students, to investigate relationships between students’ rational number knowledge and algebraic reasoning. Implications for teaching are explored in this…
Publication | This study explores the effects of geographic information systems (GIS) curriculum on fifth-grade students' spatial ability and map-analysis skills.
Publication | This monograph is a report on a four-year-long multisite longitudinal study that studied children’s thinking and learning about geometric measurement (i.e., length, area, and volume).
Publication | Noticing students' mathematical thinking is a key element of effective instruction, but novice teachers do not naturally engage in this practice. Prospective secondary school mathematics teachers were engaged in an intervention grounded in…
Publication | To make sense of the Common Core State Standards mathematical practice (MP) 8, this article illustrates what “repeated reasoning” means, why looking for and expressing regularity in it is such a valuable mathematical habit of mind, and how that…
Product for Educators | Three middle school science curricular units on the topics of genetics, ocean biodiversity & discourse, and solar ovens & design critiques.
Publication | This book examines the extent to which study quality, assessment type, and scaffolding characteristics (strategy, intended outcome, fading schedule, scaffolding intervention, and paired intervention) influence cognitive student outcomes.
Publication | This book focuses on the preparation of secondary science teachers to teach science to English Learners (EL) and is based on the SSTELLA (Secondary Science Education with English Language and Literacy Acquisition) project that has been…
Publication | The state of Florida has taken an unprecedented approach to teacher professional development in its Race to the Top
(RTTT) Program application by proposing to promote an international innovation that originates in Japan, “lesson study,” as
a…
Publication | The importance of valuing student ideas in science education stands on firm empirical, theoretical, and moral grounds. However, the reasons for which one might value student ideas are often not explicitly distinguished, even if implicit…
Publication | This study tests that logic model by comparing the high school experiences and achievement of students in ISHSs and comparison schools in North Carolina.
Publication | Current intervention research in special education focuses on children's responsiveness to teacher modeled strategies and not conceptual development within children's thinking. As a result, there is a need for research that provides a…
Publication | This study presents empirical estimates of average program change in MKT and its variation with the goal of supporting the design of experimental trials that are adequately powered to detect a specified program effect.
Publication | This study raises questions and makes suggestions for future educative curriculum development and teacher preparation.
Publication | We analyzed 37 PSTs’ written solutions to four figural pattern generalization tasks, video recordings of class discussions, and audio-recordings of problem-based interviews during which the PSTs were asked to solve one pattern generalization…
Publication | This report summarizes the 2013, 2014, and 2015 findings from a longitudinal survey of district professional development coordinators across the state of Florida. The results are presented with six sections: 1) District policy and practice, 2)…
Publication | This report describes how particulate diagrams were incorporated in a high school chemistry course, provides a rubric developed for assessing students’ particulate drawings, and summarizes the impact of particulate-level instruction on student…
Publication | The logic underlying inclusive STEM high schools (ISHSs) posits that requiring all students to take advanced college preparatory STEM courses while providing student-centered, reform-oriented instruction, ample student supports, and real-world…
Publication | This article describes the use of RD design to evaluate the impact of a supplemental algebra-readiness curriculum, Transition to Algebra, on students’ mathematics outcomes.
Publication | This article provides a framework for making sense of common online teacher learning opportunities. It also suggests situations where online professional development may be most useful and presents a challenge for educators to consider when…
Publication | This article presents a framework for calculating statistical power for moderator effects at all levels for two- and three-level CRTs.
Publication | This article describes the process of developing and validating a Science Instructional Practices survey instrument that is appropriate for NGSS and other related science standards.
