DRK-12 Research and Products
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.
Prompting meaningful analysis from pre-service teachers using elementary mathematics video vignettes
Publication | By altering the framing conditions that accompany video clips posted to the Everyday Mathematics Virtual Learning Community, this study examined whether more deeply analytical comments could be elicited from pre-service teachers.
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 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.…
Product for Educators | Three middle school science curricular units on the topics of genetics, ocean biodiversity & discourse, and solar ovens & design critiques.
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 | 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 | 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 | This paper describes model construction practices used by scientifically trained experts.
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 | 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…
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 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 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.
Product for Educators | DiALoG stands for Diagnosing the Argumentation Levels of Groups. It is designed for teachers to formatively assess the quality of evidence-based arguments and to guide the selection of instructional responses designed to Improve the…
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 | 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 | A Pleasure to Measure will enable you to select activities quickly, easily, and confidently to target the content that your students are ready to learn. You’ll find everything that you need in the six E’s that the authors detail for each…
Publication | This article explores middle school girls' reflections about the difficulties they faced while using computational algorithmic thinking capabilities as they engaged in collaborative game design for social change. Authors focus on how these…
Publication | In this paper, authors explore collaborative music live coding (CMLC) using the live coding environment and pedagogical tool EarSketch. In particular, we examine the use of turn-taking and a customized chat window inspired by the practice of…
Publication | This study investigates strategies teachers use to support mental imagery during model-based science class discussions.
Publication | In this study, we challenge the deficit perspective on mathematical knowing and learning for children labeled as LD, focusing on their struggles not as a within student attribute, but rather as within teacher-learner interactions. We present two…
Publication | This guide delivers all the tools you need to get serious about mathematical argumentation and bring well-planned, well-constructed mathematical discourse to life in your classroom.
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.
