Explains a method of exploiting recent interest in automobile safety to demonstrate, qualitatively, concepts of momentum and energy. (GS)

Creation of a computer-based interactive television system appears to have strong potential for instruction demanding motion, and for individualized instruction. If upon creation it does prove to have significant effect many questions will be raised, such as: How does effective development occur? What TV production techniques are most effective…

The purpose of this study was to assess Welford's dual controlling factor interpretation of Fitts' Law--describing movement time as being a linear function of movement distance (or amplitude) and the required precision of the movement (or target width). Welford's amplification of the theory postulates that two separate processes ought to be…

Fundamental concepts of motion are presented in this first unit of the Project Physics textbook. Descriptions of motion are made in connection with speeds, accelerations, and their graphical representation. Free-fall bodies are analyzed by using Aristotle's theory and Galileo's work. Dynamics aspects are discussed with a background of mass, force,…

This document is devoted to articles on the Open Corridor program, especially as it concerns parent participation. The first piece, "Letter from the Director," discusses trends in the parent participation aspect of the program, including problems for parents and teachers. It notes that a major problem for parents in the program has been…

This study investigated the progressive development in movement and movement patterns of children ages 2-6. Data were collected over a 3-year period at six-month intervals, based on films of 57 children performing 25 motor tasks. The results are presented along two dimensions: (1) Descriptive analysis of progress of young children in movement with…

The unit presented in this teacher's guide is the first of two developed for the fifth year in the Science Curriculum Improvement Study (SCIS) curriculum. Attention is focused on energy transfers involved in the interaction of matter in solid, liquid, and gaseous forms. The chapters are presented in six parts which include activities for reviewing…

Rudolf Laban has influenced the introduction and development of modern educational dance as well as general education. Much of the available material concerning Laban is arts oriented; it is concerned with dance as an art form and is not focused towards the educational uses of Laban's ideas. This volume attempts to present materials relevant to…

This book was designed to aid in applying the laws of dynamics to the sport of track and field, event by event. It begins by tracing the history of the discoveries of the laws of motion and the principles of dynamics, with explanations of commonly used terms derived from the vocabularies of the physical sciences. The principles and laws of…

The article describes ways in which children can develop perceptual motor coordination while engaging in activities and games wearing halloween masks with taped-over eyes. (CD)

As a continuation of SE 516 125 (The Powered Phase), this report provides a detailed analysis of the coast phase of a model rocket trajectory. (CP)

Explains the mechanism and basic physics that govern the growth of a single raindrop by condensation and droplet capture, and such properties as its falling speed, shape, and stability. (Author/GA)
