Presents an energy function E(p) containing a single integral and one variational parameter, alpha. Represents all two-electron integrals within the local density approximation as a single integral. Identifies this as a simple treatment for use in an introductory quantum mechanics course. (MVL)

Presented are the results of a survey of several classes in a college of agriculture to determine whether students had different attitudes about being taught by professors vs. teaching assistants. Data indicated that professionalism and course content are the most important variables to students. (CW)

Described is a technique for taking a large monolith for the purpose of teaching soil structure. Materials and procedures are detailed. A survey of 93 students indicated that the larger monolith was preferred over the commonly used narrow ones. (CW)

Described are three physics experiments: (1) "Holographic Prism"; (2) "Teaching about Energy with the Gravicar"; and (3) "The Coherer." In each experiment, a brief description of the experiment devised is provided with diagrams and references. (YP)

Describes making a cardboard frog. Discusses the physics of various motions of the frog. Provides diagrams showing how to make the frog, the motions, and the mechanics formulas. (YP)

Discussed is the twentieth anniversary of Cornell's program on science, technology, and society (STS); one of the country's largest and most influential. Described is the current status of STS programs around the country. Surveys social problems affecting STS areas. (MVL)

Outlined are strategies for dealing with the problem of students' lack of ability to verbalize multi-syllable vocabulary words in the sciences. A pronunciation examination, the development of corollary writing skills, vocabulary development, student journals, writing exercises, and microthemes are discussed. (RT)

Points out a different and much simpler approach for the study of equilibria of multiple and heterogeneous chemical reactions. A simulation on coal methanation is used to teach the technique. An example and the methodology used are provided. (MVL)

A course where students were required to choose projects and provide studies of the feasibility, consumer need, and process design is discussed. Other projects such as advertising campaigns used to encourage student creativity are discussed. The need to keep second semester seniors interested is stressed. (MVL)

Discusses the mechanism and the change of pH during the reaction. Notes that a dramatic rise in pH occurs when the reaction nears completion. Evaluates theories by other authors. (MVL)

Gives upper level chemistry students a better understanding of the application of lasers in the field of spectroscopy. Provides three experiments to demonstrate the thermal lens effect: determination of beam profile, cell position optimization, and pKa determination. (MVL)

Describes an interdisciplinary approach to science learning in settings usually associated with the humanities or social sciences. Explains the program, its rewards and results, the self and identity seminar, why the program works, and ways of adapting the program. (RT)

Provides step-by-step procedures for developing an index which uses the Gunning Fog technique to evaluate the level of reading difficulty of textbooks. Cites examples, illustrations, and several warnings in the discussion. (RT)

Presents entropy analysis of four processes: a chemical reaction, a heat engine, the dissolution of a solid, and osmosis. Discusses entropy, the second law of thermodynamics, and the Gibbs free energy function. (MVL)

Urges a change in engineering education for developing leaders. Describes three previous revolutions in American higher education which responded to the needs of the community. Suggests lifelong education as the fourth revolution. (YP)
