Resource | Evaluating and Improving a Learning Trajectory for Linear Measurement in Elementary Grades 2 and 3: A Longitudinal Study
We examined children’s development of strategic and conceptual knowledge for linear measurement. We conducted teaching experiments with eight students in grades 2 and 3, based on our hypothetical learning trajectory for length to check its coherence and to strengthen the domain-specific model for learning and teaching.We checked the hierarchical structure of the trajectory by generating formative…

Resource | Education R&D Partnership Tool
Education research and development (R&D) partnerships have the potential to develop knowledge and resources that contribute to improved student learning. Often districts and schools are asked to participate in R&D projects, and yet, there is little guidance in the field of education R&D regarding strategies to make project partnerships effective and mutually beneficial. Based on the…

Resource | DR K-12 Science Curriculum SIG Synthesis
The mission of the DR K-12 Science Curriculum Special Interest Group (SIG) was to further explore the types of science curricula being developed by DR K-12 grantees and to better understand the types of technologies being employed. To assist the SIG with their work, EDC and Abt Associates gathered information from various sources to provide insight into the DR K-12 science portfolio. …

Resource | District Development as a Means of Improving Mathematics Teaching and Learning at Scale
This chapter focuses on research that can inform the improvement of mathematics teaching and learning at scale. In educational contexts, improvement at scale refers to the process of taking an instructional innovation that has proved effective in supporting students’ learning in a small number of classrooms and reproducing that success in a large number of classrooms. We first argue that such…

Resource | Development of Illustrations as Image Supports for English Language Learners in Large-Scale Testing: A Report on the Procedure for Designing Vignette Illustrations
This paper presents a framework and a procedure for developing vignette illustrations as a form of testing accommodation for English language learners (ELLs). Vignette illustrations are defined as illustrations added to test items originally created without illustrations, with the intent to provide a visual support for ELLs that increases their chances of accessing the content of those test items…

Resource | Developing symbol sense for the minus sign
Research on how students make sense of and use the minus sign indicates that students struggle to understand the multiple meanings of the minus sign. Teachers can support students in developing robust understanding of each interpretation of the minus sign, and associated symbol sense, so that they can move among the meanings and can recognize and use each meaning seamlessly.

Resource | Designing Digital Experiences for Positive Youth Development: From Playpen to Playground
With the advent of the digital age, research on the psychological impact of youth engagement with technology has surged. New technologies have often taken the blame for promoting negative (and potentially dangerous) youth experiences, such as cyber-bullying, sexual predation, privacy invasion, addiction to videogames, and exposure to violence. For many children and adolescents, however, digital…

Resource | Defining Visions of High-Quality Mathematics Instruction
By synthesizing what has been learned with regard to critical dimensions of mathematics classroom teaching and learning, and investigating the ways teachers and other school personnel characterize high-quality mathematics instruction, this study defines the notion of ‘instructional vision’ and provides an initial categorization scheme. Motivating this work is the need to reliably document change…
