DRK-12 Research and Products
Product for Educators | The Flipped Mathematics Study offers advice on how to use video to teach math remotely.
Presentation | This NCTM 100 Days of Professional Learning webinar explores the cycle of inquiry and justification, conceptual obstacles, and strategies for overcoming these obstacles.
Publication | The purpose of this study was to investigate how teachers understand one specific aspect of proportional reasoning - the extent to which practicing teachers were able to make sense of reasoning that involved the fixed number of variable-sized…
Publication | Students’ difficulties with argumentation, proving, and the role of counterexamples in proving are well documented. Students in this study experienced an intervention for improving their argumentation and proving practices. The…
Publication | In this study, authors examined middle-school students’ naturally occurring design conversations in small design teams and their learning of science as a result of engaging in an engineering and science unit.
Publication | Science teachers must sometimes teach outside of their expertise, and this type of teaching assignment is referred to as being out-of-field. Among newly hired teachers, this type of assignment may have a detrimental impact in the development of…
Publication | Research has provided evidence of the value of producing multiple representationsof content for learners (e.g., verbal, visual, etc.). However, much of the research has acknowledged changes in visual technologies while not recognizing or…
Publication | We draw on our experiences researching teachers’ use of student thinking to theoretically unpack the work of attending to student contributions in order to articulate the student mathematics (SM) of those contribution.
Publication | This study is a case of using second-order models of students’ mathematical thinking to differentiate instruction, and it reveals that inquiring into research-based knowledge and inquiring responsively into students’ thinking are at the heart of…
Publication | This research focuses on ways in which balance scales mediate students’ relational understandings of the equal sign.
Publication | Several recent studies have focused on helping students understand the limitations of empirical arguments (e.g., Stylianides, G. J. & Stylianides, A. J., 2009, Brown, 2014). One view is that students use empirical argumentation because they…
Product for Educators | A digital tool that offers compelling student middle grades math problems and provides students with assessment tools and a dynamic learning map.
Publication | In this chapter, authors use the Framework for Teaching Practice (Grossman, et al., 2009) as a conceptual tool for analzying the design of professional development.
Publication | In this chapter, the authors present the design rationale for and empirical results from a predominantly synchronous three-part online model for the professional development of mathematics teachers in rural contexts.
Publication | Ambiguity is a natural part of communication in a mathematics classroom. In this paper, a particular subset of ambiguity is characterized as clarifiable. Clarifiable ambiguity in classroom mathematics discourse is common, frequently goes…
Publication | In this paper, authors offer a framework for teacher monitoring routines—a consequential yet understudied aspect of instruction when teachers oversee students’ working together.
Tool | What kinds of questions should guide investigations of matter? The Questions to Investigate task is intended to elicit preservice teachers’ content knowledge for teaching (CKT) related to asking questions to frame investigations of changes in matter.…
Publication | This Research in Science Education article focuses on characterizing classroom discourse in science.
Publication | This book aims to advance ongoing debates in the field of mathematics and mathematics education regarding conceptions of argumentation, justification, and proof and the consequences for research and practice when applying particular conceptions…
Product for Educators | Transforming Engineering Education for Middle Schools (TEEMS) is a free engineering curriculum for gr. 6-8 learners with units on the engineering design process and materials and tools that connect engineering to NGSS science topics of…
Decomposing Practice in Teacher Professional Development: Examining Sequences of Learning Activities
Publication | In this paper, authors analyze a PD design, examining its activities and the sequencing of professional learning tasks.
Publication | From a network perspective, self-regulated learning (SRL) can be conceptualized as networks of mutually interacting self-regulatory learning behaviors. Nevertheless, the research on how SRL behaviors dynamically interact over time in a network…
Publication | This article investigates whether teachers’ subject matter knowledge (SMK) and knowledge of students’ misconceptions (KOSM) in high school life science are associated with students’ posttest performance on multiple-choice test items designed to…
Tool | How can we align activities with instructional goals to support student understanding of matter and materials? The Building a Tower Task is intended to elicit preservice teachers’ CKT about descriptions and appropriate uses of materials based on their…
Publication | This article examines the teacher learning that results from participating in a two-year professional development intervention that combined lesson study, video clubs, and animation discussions.
