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 the results of introducing cooperative learning tutorials into large first-year physics classes at the University of Sydney. Finds that students attending more than half the total number of tutorials scored significantly better than those attending less than half. Student reaction to the tutorials was generally positive. Contains 31…

Describes an experience using a computer simulation on air resistance. There appeared to be differences in how students approach learning in interactive physics learning environments with and without the simulation. (Contains over 20 references.) (Author/WRM)

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…

This instructional design looks at momentum in physics through railroading, to assist students in developing appropriate mental models that will enable them to solve problems relevant to the process or principle being taught. A PEAnet (process, entity, activity network) relationship enables an instructional visualization (simulation) in which…

Explains how students can perform a refutation of the ether theory using information from the Global Positioning System (GPS). Discusses the functioning of the GPS, qualitatively describes how position determination would be affected by an ether wind, and illustrates the pertinent ideas with a simple quantitative model. (WRM)

This article describes a lesson in which students construct Bohr's planetary model of the atom. Niels Bohr's atomic model provides a framework for discussing with middle and high school students the historical development of our understanding of the structure of the atom. The model constructed in this activity will enable students to visualize the…

Research on conceptual change is still a powerful framework for empirical investigations on students' learning of science. During recent years, an increasing body of research has explored students' concepts prior and subsequent to instruction, leading to an extensive documentation of students' concepts including the difficulties and opportunities…

This paper focuses on the cognitive processes that occur while students are exploring motion graphs. In a classroom experiment, we examine how high-school students (aged 17), with backgrounds in calculus and physics, interpret the graphs they create through drawing the path of the movement of their hand with a computer mouse. Based on recent, and…

The following article presents a proposal for the redesign of a traditional course in Differential Equations at Middle Georgia College. The redesign of the course involves a new approach to teaching traditional concepts: one where the understanding of the physical aspects of each problem takes precedence over the actual mechanics of solving the…

Introduction: This research addresses preschoolers' intuitive understanding of rectilinear movement and some variables which affect it, and the type of arguments used when related knowledge states are justified. A first working hypothesis is that the resolution of practical, functional situations would be based on self-regulation processes. A…

The introduction of the Force Concept Inventory (FCI) by David Hestenes and colleagues in 1992 produced a remarkable impact within the community of physics teachers. An instrument to measure student comprehension of the Newtonian concept of force, the FCI demonstrates that active learning leads to far superior student conceptual learning than…

In the literature, learners' cognitive development is mainly discussed with respect to changes in learners' content-dependent knowledge (conceptual change or growth). Additional dimensions of time and complexity may also be taken into account to describe cognitive processes in at least three dimensions. We discuss these three dimensions of…

The current paradigm in science education calls for greater emphasis on guiding students in active and extended scientific inquiry. This is supported by research suggesting that using a hands-on approach to learning fosters ownership in the learning process and allows students to gain greater appreciation for the design and implementation of…

This article describes an exploratory case study of secondary school physics teachers' conceptions of scientific evidence. The nature of teachers' conceptions of evidence was derived from an analysis of data collected from 1 preservice and 2 in-service teachers. Each teacher responded to a series of research prompts in multiple interviews and…
