In this address, Dorothy H. Cohen admonishes teachers to remain aware that in the classroom they are both teachers and observers trying to find clues to understanding and interaction. Because teachers are human beings with attitudes and beliefs of their own, it is difficult to be objective in making observations of children. An open mind ready to…

This document is a description of Project HOPE (Health and Optimum Physical Education) directed at teachers. The ultimate goals of this project are that: (a) every child will be taught to move within his own capability and will never be embarrassed because he is not as good as somebody else; (b) every child will feel good about himself because he…

The self-instructional booklet is designed to teach basic concepts of graphical kinematics if a step-by-step procedure is followed through the various frames. Each frame is composed of three main parts: (1) a statement of information, (2) a problem to be solved or a statement to be answered, and (3) the correct response. The answer sheet form and…

The author presents a practical, workable framework for teaching dance in the classroom. This book, essentially designed for the nonspecialist teacher, is a compilation of ideas and materials that have evolved over twenty years of teaching music and movement to children in nursery and elementary schools and of introducing concepts of dance to…

Children seem to learn language more quickly when movement precedes language use. (JH)

The conceptual steps that first led Galileo toward his principle are reconstructed showing that his thoughts on the subject of motions that are neither natural nor forced were of fundamental importance. (MP)

An analysis of the minimum stopping distance problem is presented taking into account the effect of weight transfer on nonskidding vehicles and front- or rear-wheels-skidding vehicles. Expressions for the minimum stopping distances are given in terms of vehicle geometry and the coefficients of friction. (Author/BB)

Comments on a news item on rail traffic that is meant to promote conservation of energy. (GA)

Reviews Galileo's experiments with falling bodies conducted at the Tower of Pisa. Results indicate it is doubtful that he could have obtained the results claimed in the legend. (SL)

Discusses the difficulty of predicting wave structure of two phase gas-liquid flow in pipes. (SL)

Because previous studies had suggestd that Down Syndrome subjects did not respond to changes in directional probability within a complex motor task as did other retarded subjects, 14 Down Syndrome 18-year-olds were given training relative to the directional probability component of the task. Performance was improved but primarily in terms of…

As devices for measuring physical activity become more accurate and economical, researchers use them to study topics ranging from the aerobic capacity of children to the job performance of military aircrews. This article discusses various activity monitoring devices and their application. (Author/JL)

Describes the design and use of a projectile motion apparatus to illustrate a variety of projective motion results typically discussed in an introductory course. They include independence of horizontal (constant speed) and vertical (constant acceleration) motions, parabolic path shape, and other types of motion. (JN)

Describes an experiment in which the final speed of a toy car is predicted by measuring the elastic potential energy stored in its spring at the start and the energy lost to friction during the run. Conservation of energy is discussed and the necessary mathematical formulas are presented. (BC)

Epicycloids are formed by tracing the path of a fixed point on a circle as it rolls aroung the outside of a larger circle. Examines several possibilities related to epicycloids (and hypocycloids), presenting more mathematical patterns and artistic shapes that result from using several computer programs. Program listings are included. (JN)
