This paper describes the use of interactive, Physlet[R]-based curricular material designed to help students learn concepts of thermodynamics with a particular focus on the use of kinetic theory models. These exercises help students visualize ideal gas particle dynamics and engine cycles, make concrete connections between mechanics and…

The current review focuses on the construct of psychopathy, conceptualized as a clinical entity that is fundamentally distinct from a heterogeneous collection of syndromes encompassed by the term "conduct disorder". We will provide an account of the development of psychopathy at multiple levels: ultimate causal (the genetic or social primary…

This article presents an overview of some methods and results from our continuing studies of genetic and environmental influences on dyslexia, and on individual differences across the normal range that have been conducted over the past 25 years in the Colorado Learning Disabilities Research Center (CLDRC) and in related projects. CLDRC…

Describes the use of disc or ring magnets magetized axially and iron discs, in conjunction with an overhead projector, as a model of nuclear structure and of complete molecules. (GS)

Describes how to use the distinctive properties of osazone formation in conjunction with molecular model construction to demonstrate the relationship between the three-dimensional structures of simple sugars and the shapes of crystals they form. (BR)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Describes an experiment designed for second-level summer school chemistry students enrolled in Great Britain's Open University. (GS)

Describes a dry-lab experiment in which the student is provided with a set of fluorescence spectra of quinine for study and interpretation. (MLH)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

A number of phase transfer catalysis reactions are illustrated. (CP)

Proposes use of the Hammett relationship in the framework of a frontier orbital method for explanation of chemical reactivity. (CP)

Introduces a simple one-dimensional model of a diatomic molecule that can explain all the essential features of a real two particle quantum mechanical system and gives quantitative results in fair agreement with those of a hydrogen molecule. (GA)

Described is the use of molecular model kits in high school biology class and gives a laboratory unit for studying molecular structures of fats, proteins, and carbohydrates. (BB)
