DRK-12 Research and Products
Publication | This study explores the effects of geographic information systems (GIS) curriculum on fifth-grade students' spatial ability and map-analysis skills.
Publication | In this article, we explore how students attempt to bridge from their whole number reasoning to integer reasoning as they solve subtraction problems involving negative numbers.
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 | 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…
Product for Educators | Three middle school science curricular units on the topics of genetics, ocean biodiversity & discourse, and solar ovens & design critiques.
Publication | This study investigated relationships between changes in certain types of coaching knowledge and practices among mathematics classroom coaches and how these explain changes in the attitudes, knowledge, and practice of the teachers they coach.…
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 paper describes model construction practices used by scientifically trained experts.
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…
Tool | The Practicum Academy to Improve Science Education (PRACTISE) is a professional learning program to support scientific argumentation in grades 3-5. This handbook provides detailed information on how to conduct a series of research-based professional…
Publication | The results from these analyses are intended to guide researchers in making more-informed decisions about the tradeoffs and considerations involved in selecting study designs for assessing the impacts of professional development programs.
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 | In this study we articulate a multi-level scientific Modeling Practices Framework derived from expert studies on model based teaching strategies in classrooms and examine its usefulness in an actual classroom context.
Publication | A first-year algebra student’s curiosity about factorials of negative numbers became a starting point for an extended discovery lesson into territory not usually explored in secondary school mathematics.
Publication | To understand the mathematics writing of students, we conducted a synthesis to evaluate empirical research about mathematics writing. We identified 29 studies that included a mathematics-writing assessment, intervention, or survey for students…
Publication | This article explores the ways in which a teacher educator uses digital technology to create a virtual field placement to blur the boundaries between a university methods course and teacher candidates' field placements.
Publication | In this conference paper, authors discuss affordances and liabilities of using a storyboard to depict a written case of a teacher’s dilemma that involves race, opportunity to learn, and student community.
Publication | In this study, we surveyed 42 middle school science teachers and conducted follow-up interviews with 25 to investigate the factors that teachers believe impact their argumentation instruction.
Publication | In this study we investigated eighth grade students’ informal justification for the circle area formula to expand accounts of the measurement knowledge for middle-school age students.
Product for Educators | The Journey to El Yunque curriculum introduces students to disturbance ecology, with a focus on both ecosystem resilience and ecosystem change. Each page is beautifully illustrated by Puerto Rican artist Robert Casilla to connect…
Publication | The purpose of this study was to compare the ability of different instruments, independently developed and traditionally used for measuring science teachers’ beliefs in short-term interventions, to longitudinally measure teachers’ changing…
Publication | How can research-based findings and advances help society to re-envision STEM learning and education? This report captures key takeaways, strategies, and challenges identified during the November 2015 workshop, including: research-based advances…
Publication | This paper describes a strategic process for using formative assessment probes to gather and interpret evidence of student mathematics understandings and misconceptions and then targeting instruction to address identified needs.
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.
