Presents an existence proof of how preservice science teachers used analogies embedded in their course materials, Physics by Inquiry. Reports three distinct roles of analogies: a) cognitive process skills; b) scientific conceptual understanding; and c) social contexts for problem solving. Agrees on the importance of collaborative problem solving…

Explains that thinking like a physicist involves an understanding of the scientific methods of inquiry and the ability to use these methods in investigations. Describes two simple experiments in which high school and college students measure physical constants and make an easy analysis of their experimental data by applying the tools offered by…

Introduces an alternative method to determine the mechanics of a moving object that uses computer vision algorithms with a charge-coupled device (CCD) camera as a recording device. Presents two experiments, pendulum motion and terminal velocity, to compare results of the alternative and conventional methods. (YDS)

Describes the implementation of a new laboratory-based, interdisciplinary undergraduate course on linear dynamical systems. Focuses on geometrical methods and data visualization techniques. (Contains 20 references.) (Author/YDS)

Analyzes a simple boom structure and assesses its reliability using elementary engineering mechanics. Demonstrates the power and utility of Monte-Carlo simulation by showing that such a simulation can be implemented more readily with results that compare favorably to the theoretical calculations. (Author/MM)

Presents part of a project that introduces a sufficient, simple, and relevant teaching approach to quantum mechanics into in-/pre-service teacher education and provides teachers with the indispensable scientific knowledge and epistemological base needed for reform in science education. (Contains 54 references.) (Author/YDS)

Presented are directions for making a flexible lens that can be used by students to show the bending of light rays. Diagrams are included for supplementing the activities. (KR)

Discussed is a common error made by students in judging the distribution of the magnetic field of a circular loop along its diameter. Qualitative and quantitative explanations of the magnetic field distribution are presented. (CW)

Described is a demonstration which uses two electrodes attached to a piezoelectric buzzer that operates when inserted into a lemon. The calculation of cell potentials and the effects demonstrated are discussed. (CW)

The concept of displacement center for teaching the virtual work method in statistics is described. An analytical treatment of the displacement center is presented. An example which illustrates the essential elements of this concept is provided. (CW)

Presented is an experiment which provides a study both of the end correction involved with open pipes and also of the effect that varying the size of the tone hole in the pipe has on its fundamental frequency. Discussed are equipment, formulas, background, and methods. (CW)

Applications of this model to problems associated with basic phenomena in radioactivity, heat transfer, neutron chain reactions, RC circuits and vacuum pumping are presented. Example computations for each situation are included. (CW)

An outdoor activity that demonstrates the Doppler effect is described. Class predictions are verified by actual involvement in collecting data. Presented is a method of analyzing data. Safety concerns are discussed. (KR)

Student perceptions of the behavior of physics teachers in relation to selected variables in the classroom setting were investigated. High correlations between student perceptions of teacher behavior and affective outcomes are reported. (CW)

Reports on a survey which was undertaken to provide an overview of the biology content of a selection of General Certificate of Secondary Education science syllabuses. Lists syllabuses examined and the four themes in terms of which they were analyzed. Concludes that each contained a substantial biology component. (RT)
