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 | Design Patterns for Assessing Model-Based Reasoning (Large-Scale Assessment Technical Report 6)
Understanding, exploring, and interacting with the world through models characterizes science in all its branches and at all levels of education. Model-based reasoning is central to science education and thus science assessment. Building on research in assessment, science education, and learning sciences, this report provides a set of desgin patterns to help assessment designers,…

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…

Resource | Conceptual Framework for Analyzing and Designing Illustrations in Science Assessment: Development and Use in the Testing of Linguistically and Culturally Diverse Populations
We present a conceptual framework for designing and analyzing illustrations used in science assessment. This conceptual framework is intended to help test developers to systematically create and examine illustrations used in science test items. Unlike previous approaches to examining illustrations, which rely on the use of vague or polysemic termsto describe illustrations (e.g., graph, diagram),…

Resource | Common Misconceptions about Heat and Insulation
The concepts of energy and heat are challenging for elementary students. Because young students are not ready to delve into kinetic theory and molecular motion, much of the explanation of heat and energy transfer is inaccessible to them. In addition, the use of the word "energy" in popular culture may interfere with the development of scientific understanding. Nevertheless, elementary students…

Resource | Change Thinking for Global Science: Fostering and Evaluating Inquiry Thinking About the Ecological Impacts of Climate Change
Project Summary During the lifetimes of our current middle and high school students, it is likely that our planet will undergo more anthropogenic change than it has during all of human history to date. The project is utilizing a learning progression approach for the systematic design of coordinated curriculum, tool, and assessment products focused on climate change biology. This work will provide…

Resource | Appraising lexical bundles in mathematics classroom discourse: Obligation and choice
Working from a large corpus of transcripts from secondary mathematics classrooms, we identify patterns of speech that encode interpersonal positioning. We extend our analysis from a previous article (Herbel-Eisenmann, Wagner & Cortes, Educ Stud Math, 2010, in press), in which we introduced a concept from corpus linguistics—a “lexical bundle,” which has been defined as a group of three or more…

Resource | Analyzing Educational Policies as Designs for Supporting Learning
Submitted to The Journal of the Learning Sciences In this article, we describe and illustrate an analytical perspective in which educational policies are viewed as designs for supporting learning. This learning design perspective is useful when designing policies, when adapting policies to particular school and district settings during implementation, and when revising policies after…
