Discussed is wavelet theory, which provides ways to rearrange data to reveal features of a physical or mathematical system which might otherwise be hidden. This theory is compared to fourier analysis and the advantages of wavelet theory are stressed. Applications of this technique are suggested. (CW)

Described are features of a theoretical model for fluid pressure. Analyzes six introductory physics textbooks based on an introduction and meaning of the pressure concept; characteristics of pressure; and liquid as a pressure transmitter. Presents three models of pupils' conceptions. (YP)

Introduces a computer solution of the oscillation of a mass suspended by a spring in a viscous liquid. Describes the equations of motion, spreadsheet solution, copying the formulas, plotting the results, and extending the applications. Presents spreadsheet and physics formulas for the step-by-step solution and spreadsheet solution. (YP)

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

Evaluates five courseware packages covering the topics of Newton's laws and seven courseware packages for work, energy, momentum, and conservation laws. Discusses the price, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each courseware. Selects some packages based on the criteria. (YP)

Answers a student's question about the emission of a positron from a nucleus. Discusses the problem from the aspects of the uncertainty principle, beta decay, the Fermi Theory, and modern physics. (YP)

Describes classroom activities and models for migration, mutation, and isolation; a diffusion model; Bernoulli's principle; sound in a vacuum; time regression mystery of DNA; seating chart lesson plan; algae mystery laboratory; water as mass; science fair; flipped book; making a cloud; wet mount slide; timer adaptation; thread slide model; and…

Describes an experiment that uses the Tain Electronics TCS2 interface to investigate the relationship between force, mass, and acceleration. Discusses the following topics: assembling the system, forces in the system, software, and data analysis. (JRH)

Describes a method for determining the distance to the horizon which leads to determining the radius of the Earth. The article answers two interesting science questions: (1) Can you see the state of Kansas from Pike's Peak in Colorado? and (2) Can you see two sunsets in one day on the Keys of Florida? (MVL)

Describes some inexpensive activities and demonstrations that illustrate basic concepts that are often overlooked, as a low-cost means to foster student participation in physics classes. Activities described deal with acceleration and forces, freefall, conservation of energy and momentum, conservation of angular momentum, and resonance. (JRH)

Describes a set of displays on the theme of coupled mechanical oscillators. Displays encompass three common demonstrations: (1) a coupled pair of identical pendulums; (2) a multiple-pendulum resonance demonstration; and (3) a Wilberforce coupled oscillator. (MDH)

Discusses solutions to the problem of maximizing the range of a projectile. Presents three references that solve the problem with and without the use of calculus. Offers a fourth solution suitable for introductory physics courses that relies more on trigonometry and the geometry of the problem. (MDH)

Discussed are teaching methods that can be used in association with amusement park rides. The basic principles behind the effects of several rides are reviewed and illustrated. (CW)

Ten demonstrations of a variety of physics concepts are presented. Included are procedures and explanations of the effects illustrated. (CW)

Analyzing the paradigmatic shift from Peripatetic to Galilean physics can help to understand students' difficulties in learning Newtonian mechanics. Promotes the use of historical texts in physics teaching as a means to support students in becoming aware of the structural differences between everyday life and scientific views of the world.
