The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

A principle is presented to show that, if the time of passage of light is expressible as a function of discrete variables, one may dispense with the more general method of the calculus of variations. The calculus of variations and the alternative are described. The phenomenon of mirage is discussed. (Author/KR)

Describes several ways to partially levitate permanent magnets. Computes field line geometries and oscillation frequencies. Provides several diagrams illustrating the mechanism of the oscillation. (YP)

The dynamics of some common sports, such as race walking, running, cycling, jumping, and throwing, are presented. Rough estimates of the relevant physical quantities required for these individual sports are discussed. General mathematical formulas are derived which can be used for judging the performance of any athlete. (Author/KR)

Using a physical picture, an expression for the maximum possible transverse velocity and orientation required for that by a linear emitter in special theory of relativity has been derived. A differential calculus method is also used to derive the expression. (Author/KR)

Applications of physics concepts related to the activities of dinosaurs are presented. Problems of mass, speed and motion, and sound are discussed. Solutions to the problems are shown. (CW)

Presents methods for estimating running speed, length of a broad-jump, height of a pole vault, and time to run up a flight of steps as examples of elementary numerical mechanics. (SL)

Presents a calculator-type computer program, CLICAL, in conjunction with complex number, vector, and other geometric algebra computations. Compares the CLICAL with other symbolic programs for algebra. (Author/YP)

The simple physics behind the mechanism of the toy are explained. Experimental and mathematical steps are given that help in understanding the motion of the doll-pair. The geometry of the setup is described. (KR)

Described is the use of an interactive terminal-oriented computing system that has access to files of thermodynamics data. (Author/SA)

Described is an activity in which students examine data collected from an official report of a train accident to evaluate the conclusions of the official investigation. Quotations from the records and calculations used in this activity are included. (CW)

Presented are problems that teachers can use to stimulate students' thinking about the subject of mathematical scaling. Food and eating examples are used to illustrate this concept. (CW)

Presented is an example of this use of spreadsheet software. The basic case is considered with an extension and suggestions for other applications. Emphasized is the use of this method at the introductory level. (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)

Described is an activity in which groups of students investigate engineering principles by writing a feasibility study to raise the luxury liner, Titanic. The problem statement and directions, and suggestions for problem solutions are included. (CW)
