Summarizes research into how children perceive three-dimensional objects. Focuses on the difficulty that students have in appreciating how the orientation of the semicircular canals affects balance and space perception. (DDR)

Describes a procedure developed by students that measures the mass concentration of particles in a polluted urban atmosphere. Uses a portable fan and filters of various materials. Compares students' data with official data. (DDR)

Reports on research that aimed to establish whether patterns of students' reactions to and achievement on physics assessment tasks were associated with the format of the task and the absence or presence of real-world contexts in the tasks. Contains 21 references. (DDR)

The Hands-On and Far-Out Physics project is part of the Center for Technology, Environment, and Communication (C-TEC), a project-based learning community at Piner High School in Santa Rosa (California). This article introduces the project team, discusses member activities, presents a walking-speed experiment, and describes a Mars Colony course…

Describes procedures for a demonstration that features an exploding can. This demonstration prompts students to critically analyze the release of energy in an exothermic reaction, the work done in such a reaction, and the enthalpy. (DDR)

Examines the attitudes of physics instructors on how and when students should be allowed access to textbook problem solutions. Presents a detailed analysis of 249 survey responses from U.S. and Canadian universities which conveyed a wide range of opinions and comments. Discusses the need to rethink strategies regarding access to solutions. (AIM)

Compares the Japanese educational system with that in England. Discusses the structure of school levels and examinations, the curriculum, and informal educational practices and cultural expectations. Notes the place of science study in the Japanese system. (Author/WRM)

Discusses the Advanced Placement (AP) Physics program in the U.S. in terms of which of its aspects may be applied to education in the United Kingdom. Suggests that a British AP scheme giving access to introductory-level college physics for the brightest students may be needed in light of proposed A-level curriculum changes in the U.K. (Author/WRM)

Reports on a study of a physics class in which few interactions occur among students. Concludes, through observations and interviews. that students describe both the social and physical world in different ways. Contains 33 references. (DDR)

Features an assignment involving average monthly temperatures that can serve as an example of curve-fitting for a periodic function. (WRM)

An American Institute of Physics survey was modified to determine major physics topics emphasized in small Missouri high schools and teachers' perceived adequacy to teach them. Data tables show the emphasis that 103 Missouri teachers placed on 38 physics topics, compared to national counterparts, as well as teachers' perceptions of their knowledge…

Presents an analysis of an astrophysics institute designed for high school students. Investigates how students respond cognitively in an active science-learning environment in which they serve as apprentices to university astrophysics professors. (Author/CCM)

Describes the organization and completion of a scientific field trip for a group of high school physics students that was organized primarily around a study of the Manhattan Project. The group visited the Trinity site, Los Alamos, several museums, and the National Radio Astronomy Observatory Very Large Array. Contact information for the various…
