DRK-12 Research and Products
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 | This paper describes a guided-inquiry activity designed for the first week of a first-year high school chemistry course.
Publication | In this article, we describe the experiences of three Elementary Mathematics Specialists (EMS) who were part of a larger project investigating the impact of EMS certification and assignment (self-contained or “departmentalized”) on teaching…
Publication | This study investigates the models of elementary content specialization (ECS) in elementary mathematics and science and the affordances and constraints related to ECS—both generally and in relation to specific models.
Publication | In this paper, we present a description of the EarSketch environment and curriculum. We also present an overview of the classroom environments in which EarSketch has been implemented to date, including professional development feedback, student…
Publication | This article considers a role for live coding that does not focus on live performance but rather on educational contexts.
Publication | This article presents EarSketch, a learning environment that combines computer programming with sample-based music production to create a computational remixing environment for learning introductory computing concepts.
Publication | In this study we explored the scientific argumentation beliefs of teachers in low, mid, and high SES schools.
Publication | This case study uses the conceptual framework of communities of practice to investigate the relationship between English-learning students' argumentation and their middle school sheltered English immersion (SEI) science classroom 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 | This study raises questions and makes suggestions for future educative curriculum development and teacher preparation.
Publication | From a social semiotic perspective, students’ use of language is fundamental to mathematical meaning making. We applied thematic analysis to examine students’ use of geometric and contextual ideas while solving a geometry problem that required…
Publication | This study investigates facilitation of professional development to promote teacher learning when using animations and videos in a study group with five teachers.
Publication | This exploratory study examines how a foundational scheme of unit fractions (1/n) may evolve through the mathematical activity of two fifth grade girls.
Publication | This paper traces the research-design-develop-test cycle of a haptically-enhanced science simulation designed to teach upper-elementary students core ideas about matter, phase change, and the role of intermolecular forces.
Publication | This white paper clarifies different purposes elementary students might write in math class and presents four types of mathematical writing. We define "mathematical writing" as writing that encourages students to engage in mathematical reasoning…
Presentation | In this November 29th webinar, NSF Program Officer David Campbell introduced DR K-12 awardees to the ins and outs of NSF DR K-12 project management.
Publication | Many teachers use online professional development websites, but little is known about what teachers actually learn from them. This study explored teacher use of an online video-based learning website with over 37,000 members.
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 | Does the promise of competency-based PD outweigh the challenges to implementing it? Do we really want competency-based PD or just more effective, sustained, job-embedded PD like instructional coaching, lesson study, and the like. Read this blog…
Presentation | Variations of this slide deck were used in 3 different presentations this summer about the Teachers with Guts project.
Publication | This appendix of the California Science Framework focuses on Computer Science in Science.
