Provides an overview of the programing language PROLOG and highlights its educational uses. Explains how PROLOG serves as a model of representing commonsense understandings of motion. Identifies problem areas and proposes future tasks with the program. (ML)

Describes the "Master Classes in Physics for Young People" Saturday program offered for students in schools in Sussex, England. Explains the program format, topics addressed, and level of student involvement. (ML)

Reports on a study of position descriptions in the field of hydrogeology appearing in want ads, published studies describing the working professional, and published descriptions of hydrogeology programs. Results indicate an increase in positions of ten times that of five years ago. Suggests basic training requirements for beginning…

Provides instructions on conducting four demonstrations for the chemistry classroom. Outlines procedures for demonstrations dealing with coupled oscillations, the evaporation of liquids, thioxanthone sulfone radical anion, and the control of variables and conservation of matter. (TW)

Discusses the benefits of thermochromic transformations for studying thermodynamic properties. Describes an experiment that uses a commercially available dye, attains equilibrium rapidly, employs a simple, single-beam spectrophotometer, and is suitable for both physical chemistry and introductory chemistry laboratories. (TW)

Describes how a Polaroid camera can be modified for spectroscopic experiments. Reviews experimental procedures and discusses results that students can obtain within one normal laboratory period. Suggests additional experiments for investigating emission from other sources. (ML)

Reports on a study into the relationship between a student's ability to solve problems in chemistry and his/her understanding of molecular concepts. Argues that teaching students to solve problems about chemistry is not equivalent to teaching about the nature of matter. (TW)

Suggests chemistry should be better taught to undergraduates with more emphasis on lifelong learning experience. Emphasizes the collaboration needed between chemistry disciplines. Lists suggestions for curriculum change in chemistry. (ML)

Surveys the types of computers being used in high school and university chemistry courses. Identifies types of hardware found on Apple and MS-DOS computers. Makes recommendations for the upgrading of current equipment. (ML)

Described are the energetics involved in the formation of molecular hydrogen using concepts that should be familiar to students beginning the study of molecular orbital theory. Emphasized are experimental data on ionization energies. Included are two-electron atomic and molecular systems. (CW)

Discusses how to interpret nuclear magnetic resonance (NMR) spectra and how to use them to determine molecular structures. This discussion is limited to spectra that are a result of observation of only the protons in a molecule. This type is called proton magnetic resonance (PMR) spectra. (CW)

Details two demonstrations for use with an overhead projector in a chemistry lecture. Includes "A Very Rapidly Growing Silicate Crystal" and "A Colorful Demonstration to Simulate Orbital Hybridization." The materials and directions for each demonstration are included as well as a brief explanation of the essential learning involved. (CW)

Describes a one-semester course designed to teach first year graduate students how to extract, interpret, evaluate, and use the information provided by an X-ray crystallographic crystal structure determination. Presents a course outline and discusses the treatment of crystal composition, crystallographic parameters, molecular geometry and…

Explores how an existing program can be adapted for remote control. Compares the output on the screen of an Apple II computer with its equivalent on the braille display of the VersaBraille. Points out some of the advantages of using a data base as a customized information center. (CW)

In this article, part I of a series, the forensic methods used in "typing" human blood, which as physical evidence is often found in the dried state, are outlined. Background information about individualization, antibody typing, fresh blood, dried blood, and additional systems is provided. (CW)
