Background: In the context of recent research in science education and continued struggles to understand how best to support science teachers, epistemological frames, made up of sets of epistemological resources teachers activate, have emerged as an important focus of research. However, at the time of this writing no research was available to…

Background: Efforts to promote reform-based instruction have overlooked the import of affect in teacher learning. Drawing on prior work, I argue that teachers' affective experiences in the discipline are integral to their learning how to teach the discipline. Moreover, I suggest that both affective and epistemological aspects of teachers'…

Taking place within the Science Through Technology-Enhanced Play (STEP) design-based research project, this paper describes how first- and second-grade students use their bodies to imaginatively become microscopic particles inside of a collaborative simulation of state change (e.g., liquid to gas) and within two distinct play spaces: a…

Learning scientists often use Donald Stokes's influential characterization of the relation between basic and applied research in his book "Pasteur's Quadrant" to suggest that most of the work in the learning sciences lies, or should lie, at the intersection of both types of research, that is, in the cell that is epitomized by Pasteur's…

As secondary students' interest in science is decreasing, schools are faced with the challenging task of providing adequate instruction to engage students--and more particularly the disadvantaged students--to learn science and improve their science inquiry skills. In this respect, the integration of Web-based collaborative inquiry can be seen as a…

Field trips to science museums can provide students with educational experiences, particularly when museum programs emphasize scientific inquiry skill building over content knowledge acquisition. We describe the creation and study of 2 programs designed to significantly enhance students' inquiry skills at any interactive science museum exhibit…

Research and practice has placed an increasing emphasis on aligning classroom practices with scientific practices such as scientific argumentation. In this paper, I explore 1 challenge associated with this goal by examining how existing classroom practices influence students' engagement in the practice of scientific argumentation. To do so, I…

Participants in 2 experiments interacted with computer simulations designed to foster understanding of scientific principles governing complex adaptive systems. The quality of participants' transportable understanding was measured by the amount of transfer between 2 simulations governed by the same principle. The perceptual concreteness of the…

Explores connections between naive epistemology and everyday instructional practice. Reviews examples of naive epistemologies as made up of fine-grained, context-sensitive resources. Presents strategies designed to help students tap those resources for learning introductory physics. Reflects on this work as an example of interplay between two…

Investigates ways of prompting middle school science students to reflection. Contrasts two types of reflection prompts, generic prompts and directed prompts. Discusses the relationship between reflection types and student understanding of a science project. Describes the role of reflection in prompting multiple, complementary knowledge integration…

Describes five significant challenges to implementing inquiry-based learning. Presents strategies for addressing them through the design of technology and curriculum. (Author/CCM)

Explores student ability to differentiate and make mappings between quantities in different domains before and after a relevant curricular experience. Contends that conceptual bootstrapping involves a multistepped mapping process that is facilitated through classroom dialog, problem solving, and instruction. (Author/DKM)

Argues that role-playing activities can be a powerful tool in mathematics and science education, particularly in the new sciences of complexity (i.e., the study of complex systems). Two role-playing activities are described, each designed to help students develop better intuitions on how complex phenomena can arise from simple interactions, and…

Compares and contrasts two summer camps, Future Camp 97 based on assumptions consistent with constructionism, and Scientists Apprentice Camp 97 which is consistent with legitimate peripheral participation. Explores the nuances of learning environments based on different theoretical assumptions. (Contains 57 references.) (Author/YDS)

The notion of scaffolding learners to help them succeed in solving problems otherwise too difficult for them is an important idea that has extended into the design of scaffolded software tools for learners. However, although there is a growing body of work on scaffolded tools, scaffold design, and the impact of scaffolding, the field has not yet…
