DRK-12 Research and Products
Publication | Research on geometric transformations suggests that early learners possess intuitive understandings grounded in motion metaphors, transitioning to mappings. The processes through which students transition between these two conceptions are not…
Publication | Specific to the topic of oxidation–reduction (redox), teachers are obligated by the discipline to prioritise symbolic traditions such as writing equations, documenting oxidation states, and describing changes (e.g., what undergoes oxidation/…
Publication | In many schools across the world, students experience mathematical concepts as ideas empty of wisdom and possibility. In this paper the authors analyze a philosophical conversation in which fifth-grade students were caught up in the animacy of…
Publication | Students need “critical data literacy” skills to help make sense of the multitude of information available to them, especially as it relates to high-stakes issues of social justice. The authors describe two curriculum modules they developed—one…
Publication | Civic Statistics by its nature is highly interdisciplinary. From a cross-curricular perspective, teaching and learning Civic Statistics faces specific challenges related to the preparation of teachers and the design of instruction. This chapter…
Publication | Urban school leaders can support mathematics instruction that acknowledges and sustains students’ racialized and cultured ways of knowing and being. Yet, leadership for racial justice is often discussed separately from instructional improvement…
Legitimation Code Theory as an Analytical Framework for Integrated STEM Curriculum and Its Enactment
Publication | In this paper, we describe Legitimation Code Theory as an analytical framework and provide an analysis of semantic patterns of an integrated STEM unit (written discourse) and a middle school teacher’s enactment of that unit (oral…
Publication | Big ideas in science education are meant to be interpretive frameworks that empower student learning. Unfortunately, outside of the broad conception of scientific evaluation, there are few theoretical explanations of how this might happen.…
Publication | Science learning is an important part of the K-12 educational experience, as well as in the lives of students. This study considered students’ science learning as they engaged in the instruction of scientific issues with social relevance. With…
Publication | We need STEM knowledge programs in formal and informal settings that guide learners in applying STEM learning to the creation of solutions.
Publication | Determining the most appropriate method of scoring an assessment is based on multiple factors, including the intended use of results, the assessment's purpose, and time constraints. Both the dichotomous and partial credit models have their…
Publication | Effective K-12 integrated STEM education should reflect an intentional effort to adequately represent and facilitate each of its component disciplines in a meaningful way. However, most research in this space has been conducted within the…
Mathematics and Science Teacher Educators' Use of Representations of Practice: A Mixed Methods Study
Publication | This study sought to explore math and science teacher educators' use of various media to represent practice within methods courses. There is little understanding of why certain media is used over other representations and the rationale for these…
Publication | Review of the recent literature on integrated STEM curriculum development and implementation. Included are frameworks for integrated STEM curriculum development and research assessments to evaluate curriculum quality. Details and examples from a…
Publication | This article introduces a new framework for articulating how educational assessments can be related to teacher uses in the classroom. It articulates three levels of assessment: macro (use of standardized tests), meso (externally developed items…
Publication | Science teacher leaders have been identified as an important lever for the implementation of science education reform. However, science reform implementation is locally controlled and not uniform across districts; therefore, the work of STLs…
Publication | Adopting a pretest–posttest experimental design with repeated measures, this study examined the effects of three types of game-based learning supports in the form of modeling on knowledge development that contributed to successful math problem…
Publication | In various formats, students at the secondary and postsecondary levels participate in multiweek authentic science research projects. There have been many papers explaining the operations of such programs, but few have provided explicit…
Publication | To best support students in developing competence, assessments that allow students to use knowledge to solve challenging problems and make sense of phenomena are needed. These assessments need to be designed and tested to validly locate students…
Publication | Digital game-based math learning environments (math DGBLE) are promising platforms that provide students with opportunities to master conceptual understanding and cultivate mathematical thinking, on which the contemporary mathematics education…
Publication | The Socioscientific Issues Teaching and Learning (SSI-TL) framework is a guide for developing an instructional approach to learning experiences focused on socioscientific issues (SSI). Despite the potential benefits of SSI learning, teachers…
Publication | It is essential for items in assessments of mathematics’ teacher knowledge to evoke the desired response processes – to be interpreted and responded to by teachers as intended by item developers. In this study, we sought to unpack evidence that…
Secondary Chemistry Teacher Learning: Precursors for and Mechanisms of Pedagogical Conceptual Change
Publication | Despite years of research and practice inspired by chemistry education research, a recent report shows that US secondary instruction is not aligned with current national reform-based efforts. One means to mitigate this discrepancy is focusing on…
Publication | The Delphi method has been adapted to inform item refinements in educational and psychological assessment development. An explanatory sequential mixed methods design using Delphi is a common approach to gain experts' insight into why items might…
Publication | This book is about scientific inquiry. Designed for early and mid-career researchers, it is a practical manual for conducting and communicating high-quality research in (mathematics) education. Based on the authors’ extensive experience as…
