Reviews software packages by providing extensive descriptions and discussions of their strengths and weaknesses. Software reviewed include (1) "VISIFROG: Vertebrate Anatomy" (grade seven-adult); (2) "Fraction Bars Computer Program" (grades three to six) and (3) four telecommunications utilities. (JN)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

Challenges language educators to use the computer wisely, as a tool for more effective learning of language, which is so crucial to the building of world-wide bridges of understanding in this age of economic interdependence and nuclear threat. (Author/SED)

Describes the laboratory portion of the General Ecology course offered at California Polytechnic State University in which laboratory exercises to collect and analyze data were enriched through introduction of computerized data processing. Advantages, software development, program implementation, course specific computer usage, and student…

The impact of robotics in education is discussed in terms of academic assistance to industry in robotics as well as academic problems in handling the demands put upon it. Some potential solutions that can have lasting impact on educational systems are proposed. (JN)

Describes an undergraduate organic chemistry experiment designed to illustrate the power of nuclear magnetic reasonance spectroscopy in a determination of the configurations at centers of chirality of various isomers of acyclic systems. Provides a background discussion and experimental procedure. (JM)

Describes an experiment designed to teach students to apply the same statistical awareness to instrumentation they commonly apply to classical techniques. Uses propagation of error techniques to pinpoint instrumental limitations and breakdowns and to demonstrate capabilities and limitations of volumetric and gravimetric methods. Provides lists of…

Describes a two-semester course designed to meet the needs of future elementary teachers, home economists, and occupational therapists. Laboratory work includes homemade calorimeters, inclined planes, and computing. Content areas of the course include measurement, physics, chemistry, astronomy, biology, geology, and meteorology. (JN)

Explains: (1) the "standard" atmospheric pressure demonstration using an empty duplicating fluid can and heated water; and (2) a variation of this demonstration using an aluminum soft drink can. (DH)

This introduction to photoelectrochemical (PEC) cells reviews topics pertaining to solar energy conversion and demonstrates the ease with which a working PEC cell can be prepared with n-type silicon as the photoanode and a platinum counter electrode (both immersed in ethanolic ferrocene/ferricenium solutions). Experiments using the cell are…

Describes an experiment for plotting equipotential curves in which the normally used electrometer is replaced by a null-deflecting potentiometer, and in which the uniform resistance wire is substituted by carbon-impregnated conductive paper. Procedures and sample plot/results (including graphic analysis) are provided. (JM)

A laboratory study is detailed utilizing the skills of hypothesizing, designing experiments, and controlling variables. (EB)

One of the recurrent problems associated with interpersonal, group, organizations, and intercultural training in communication is the assessment of outcomes. An approach is suggested for the evaluation of training and selection of programs utilizing behavioral assessment of participants' communication competence. (Author)

The uses of a computer-based instructional system known as PLATO in teaching Russian, both in audio-lingual and reading-translation courses, at the University of Illinois are described. Examples of a variety of drills are given. An evaluation of the method is made. (RM)

In an interdepartmental cooperative effort, language students at the University of Maine were treated to a special show at the University planetarium. They heard their own tape-recorded voices reciting a Spanish poem about the moon, while they saw an interpretation of the poem in the planetarium sky. (POP)
