Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Provides a simplified, synoptic overview of the area of thermodynamics, enumerating and explaining the four basic laws, and introducing the mathematics involved in a stepwise fashion. Discusses such basic tools of thermodynamics as enthalpy, entropy, Helmholtz free energy, and Gibbs free energy, and their uses in problem solving. (JM)

Discusses simulation program to aid in the design of enzyme kinetic experimentation (includes sample runs). Concentration versus time profiles of any subset or all nine states of reactions can be displayed with/without simulated instrumental noise, allowing the user to estimate the practicality of any proposed experiment given known instrument…

A taxonomy which classifies different types of human movements heirarchically was developed for use in teacher education, curriculum development, and teacher behavior research. The taxonomy is related to M. Mosston's Three-Dimensional Model of Developmental Movement. The instruments permit an expanded and integrated way of categorizing movement…

Describes advances in catalytic determinations and other applications of kinetics in chemical analysis. A section on instrumentation and computers is included. Cites 158 references. (CS)

Described is a Piagetian learning cycle based on Monte Carlo modeling of several simple reaction mechanisms. Included are descriptions of learning cycle phases (exploration, invention, and discovery) and four BASIC-PLUS computer programs to be used in the explanation of chemical reacting systems. (Author/DS)

Describes an exercise involving the use of kinematics to decide if one should stop or try and get through an intersection when the traffic light turns yellow. Gives students' experience in recording data, doing simple calculations and connecting classroom studies to real world experiences. (Author/SK)

Attempts to provide an intuitive understanding of steady state kinetics. Discusses the meaning of steady state and uses free energy profiles to illustrate and follow complex kinetic and thermodynamic relationships. Provides examples with explanations. (MVL)

Explains reasons why students have misconceptions concerning pendulum swings. Presents a series of 10 pendulum task cards to provide middle-school students with a solid mental scaffolding upon which to build their knowledge of kinetic energy and pendulums. (PR)

Discusses the principles of magnetic levitation presented in the physics classroom and applied to transportation systems. Topics discussed include three classroom demonstrations to illustrate magnetic levitation, the concept of eddy currents, lift and drag forces on a moving magnet, magnetic levitation vehicles, levitation with permanent magnets…

Reviews research on student learning about collisions in physics instruction. Focus is placed on the main differences between the spontaneous perspective in describing/interpreting collisions and the disciplinary perspective based upon the energy and linear momentum conservation laws. (PR)

Details how a spreadsheet with graphics capabilities can be used to illustrate enzyme kinetics and explain how computer simulation of a reaction mechanism is accomplished. (DDR)

Describes the use of Calculator-Based Laboratory (CBL) technology and a projectable TI-83 graphing calculator to demonstrate the kinetic behavior of a complex reaction. Explains how the CBL is used to review first-order reactions and the graphing calculator is used to determine the rate constants for a series of consecutive first-order reactions.…

Presents evidence that suggests that upper elementary students can be taught about the particulate nature of matter in a meaningful way. Investigated the effects of lesson sequences on children's ability to apply a particulate understanding to chemical and physical phenomena and found conceptual gains on lesson specific phenomena. (Contains 15…

This book is written for physical educators and others interested in the performance of the human body in motion. It is divided into four major catagories: (1) The discipline of human movement and its applications; (2) human beings and function through movement; (3) human movement; applied; and (4) human movement: generative and integrated. Six…
