Describes an approach to the teaching of electricity that uses box and AVOW diagrams, novel representations of the properties of the electric circuit that portray current, voltage, resistance, and power. The diagrams were developed as aids in learning, understanding, and problem solving and to promote conceptual change by challenging a number of…

Examines the effects of using a conflict map on 8th grade students' conceptual change and ideational networks about simple series electric circuits. Analyzes student interview data through a flow map method. Shows that the use of conflict maps could help students construct greater, richer, and more integrated ideational networks about electric…

Presents a lesson involving the measurement of wood beams and the prediction and testing of their stress limits. Provides an example of a problem with multiple solutions, each with different consequences. (KHR)

Students (n=128) enrolled in 8 summer intensive physics courses for academically gifted students participated in a study to assess the effectiveness of such courses compared to ordinary year-long high school physics courses. Average gains achieved by students were comparable to those achieved by students in the ordinary-length courses. (Contains…

Presents two real world applications that use derivatives and are related to computing the distance required to stop an airplane. Examines the curve-fitting techniques used to develop an equation for braking force and develops equations for the deceleration and speed. (DDR)

Discusses the implications of withdrawing support for programs that bring amateur and professional astronomers into the schools. Provides insight into the perspectives of the scientists who are involved with schools as well as the perspective of the National Aeronautics and Space Administration (NASA). (DDR)

Highlights students' ideas about the particle model of matter and its use. Discusses the atomic model in teaching and the rules of the particle modeling game. Demonstrates how a complete understanding of the rules of the model construction yields guidelines for didactic practice. Focuses on problems connected with visual communication through…

A study of the processes by which 24 grade-12 Australian physics students brought order to their observations and practices shows that the phenomena students construct from their laboratory work (not always accurate) develop from connections among the embodied practices of language and physical action, their world, and social relations. (SLD)

A study of four seventh-graders using an open-ended learning environment (OELE) on mechanical physics combining computer-generated graphics, computer simulations, video, and print-based materials indicated that while learners built and formalized scientific theories, in some cases, they assimilated new data into existing theories, ignored…

Examines the differences in paper-based and web-based administrations of a commonly used assessment instrument, the Force Concept Inventory (FCI). Results demonstrated no appreciable difference on FCI scores or FCI items based on the type of administration. Concludes that the web-based administration of the FCI appears to be as efficacious as the…

Focuses on the role of Thought Experiments (TEs) in ongoing processes of conceptual refinement for physicists and physics learners. Analyze TEs related to stellar evolution and general relativity. Identifies the stages at which crucial errors are made in these TEs and the cognitive processes which lead to these errors. Discusses implications for…

Analyzes Korean 8th grade students' achievement in physics-related areas of the Third International Mathematics and Science Study-Repeat (TIMSS-R) and investigates the implications for revising the physics-related areas in the national curriculum. (Contains 44 references.) (Author/YDS)

Introduces a new way of evaluating instructional strategies using computers. Discusses two basic theories, instructivism and constructivism, in terms of their effectiveness in conceptual learning. Outlines the radical forms of constructivism. Introduces and evaluates two versions of a multimedia physics software based on the inventive model and…

Explores self-reflection skills and views in the context of an introductory physics course for first-year engineering honors students. Measures students' conceptual learning gains using standard survey instruments. Finds that students with high conceptual gains tend to show reflection on learning that is more articulate and epistemologically…

Explains how physics teaching can be more relevant for elementary and secondary students by integrating physics and earth science content that students can relate to and understand. Identifies and explains Earth contexts that can be appropriately implemented into the physics curriculum such as waves, magnetism, and electricity. (Author/YDS)
