Reports on a study that examined the performance and science attitudes of two groups of students in a college chemistry course. One group had enrolled in high school chemistry; the other group had not. There was no difference between groups as to attitude toward chemistry or academic performance. (RT)

Outlines the genetic elements found in the bacterial cell which play a role in recombining DNA sequences. Provides a core structure to which the mechanisms occurring in and between bacterial cells can be related. Discusses the practicalities of recombinant DNA techniques. (Author/CW)

Discusses the incompatibility of learning and teaching styles in engineering education which results in society's potential loss of excellent engineers. Provides teaching techniques to accommodate learning styles. (RT)

Lists questions that can be used to help students learn how to write letters of inquiry. States that as a result, students begin to feel less like students and more like professionals. (RT)

Describes simple, efficient techniques for treating hazardous chemicals so that nontoxic and nonhazardous residues are formed. Discusses general rules for management of waste chemicals from school laboratories and general techniques for the disposal of waste or surplus chemicals. Lists specific disposal reactions. (CW)

Describes an investigation of forces and motions in ten pin bowling. Explores the significance of the spin on the ball, its curved path and other factors which may increase the chance of a strike occurring. Discusses the ball's path and the action of the pins. (CW)

Recalls a study carried out by the European Society for Engineering Education on "Educating the engineer for innovative and entrepreneural activity." Illustrates the reasons for the increasing need for strict cooperation between universities and industry. Considers the forms in which cooperation can be established. (CW)

Describes the driving forces behind corporate education in the United States and how they have become manifested in some leading initiatives which are of importance to the engineering community. Discusses education for the world of work, corporation schools, corporate classrooms, hybrid corporate-university classrooms and government-university…

Reports on some of the discoveries over the last quarter century regarding quasars including spectra and energy sources, formation and evolution, and cosmological probes. Describes some of the fundamental mysteries that remain. (CW)

Describes the use of spectroscopy and the redshift to measure how far an object is by measuring how fast it is receding from earth. Lists the most distant quasars yet found. Tables include "Redshift vs. Distance" and "Distances to Celestial Objects for Various Cosmologies." (CW)

Details three demonstrations for use in chemistry classrooms.
