This study investigates whether Virtual Manipulatives (VM) within a Physical Manipulatives (PM)-oriented curriculum affect conceptual understanding of electric circuits and related experimentation processes. A pre-post comparison study randomly assigned 194 undergraduates in an introductory physics course to one of five conditions: three…

This article aims to account for students' assessments of the plausibility and applicability of analogical explanations, and individual differences in these assessments, by analyzing properties of students' underlying knowledge systems. We developed a model of explanation and change in explanation focusing on knowledge elements that provide a…

This article identifies aspects of argumentation in scientific practice that are key for scientific sense-making and articulates how engagement in these aspects happens both inter-mentally (between people) and intra-mentally (an individual's reasoning). Institutionally, peer review exerts critique on new knowledge claims in science and is…

The concept of framing from anthropology and sociolinguistics is useful for understanding student reasoning. For example, a student may frame a learning activity as an opportunity for sensemaking or as an assignment to fill out a worksheet. The student's framing affects what she notices, what knowledge she accesses, and how she thinks to act. We…

This study demonstrates an existence proof for "productive failure": engaging students in solving complex, ill-structured problems without the provision of support structures can be a productive exercise in failure. In a computer-supported collaborative learning setting, eleventh-grade science students were randomly assigned to one of two…

Chi (2005) proposed that students experience difficulty in learning about physics concepts such as light, heat, or electric current because they attribute to these concepts an inappropriate ontological status of material substances rather than the more veridical status of emergent processes. Conceptual change could thus be facilitated by training…

We argue that learning about the nature and utility of scientific models and engaging in the process of creating and testing models should be a central focus of science education. To realize this vision, we created and evaluated the Model-Enhanced ThinkerTools (METT) Curriculum, which is an inquiry-oriented physics curriculum for middle school…

Compared tutoring episodes where tutoring did and did not cause learning in university physics students to inform design of intelligent tutoring systems. Found that when students were not at an impasse, learning was uncommon regardless of the tutorial explanations employed. When students were at an impasse, tutorial explanations were sometimes…

Analyzed a corpus of videotapes in which university students solved physics problems to determine how students learn to understand a physics equation. Found that students learn to understand physics equations in terms of a vocabulary of elements called symbolic forms, each associating a simple conceptual schema with a pattern of symbols. Findings…

Develops a multidimensional framework for analyzing an extended physics classroom interaction to understand the resources participants use, alignments they form, and meanings and context they construct. Considers how participants negotiate their positions, focusing on one resistant student and why she remains unconvinced by others' arguments and…

Presents an account of a week of learning and instruction from a high school physics course to provide a context for discussion of the role and demands of teacher inquiry. Argues coordination of student inquiry and traditional content is a matter of discerning and responding to students' particular strengths and needs. (Author/KB)

Used computerized simulation models of qualitative, conceptual problem solving and quantitative problem solving to examine qualitative physics knowledge acquisition during textbook-based physics training. Found that qualitative knowledge was acquired on the basis of explicit textbook information, but there were also cases of qualitative learning…

Compared Introductory Physical Science (IPS) and Modified approaches to teaching physics concepts. Found that students' preinstruction ideas of matter and density were organized in commonsense theories that constrained understanding of density. Both curricula promoted quantitative understanding of mass, volume, and density, but the Modified…

A comparison of the physics concepts explanations of ninth graders and of physics graduates and graduate students found that physics novices were strongly inclined to conceptualize physics concepts as material substances, whereas experts' protocols revealed distinctly nonmaterialistic representations.

Analyzes a short excerpt from a high school physics class discussion to consider the value of the students' work as inquiry and to illustrate a teacher's negotiation of the tension between inquiry and traditional content-oriented concerns. (MDM)
