Twelve science activities involving the common paper food bag and the small plastic food bag are described. (DT)

Describes an experiment which can be used to test for the use of accelerants in the origin of a fire. Involves distillation and gas liquid chromatography to identify the accelerants, thus combining two experiments ordinarily included in the beginning organic laboratory. (SLH)

Describes the use of student projects within a traditional biology laboratory class to incorporate openness, inquiry techniques, and student choice into course teaching. Included is a list of sample investigations. (CC)

Describes an experiment in which the learning contract method was used in a philosophical ethics course and assesses the learning contract method as compared to the discussion method. (Author/PG)

Discusses offering of a modular course designed to acquaint the student with methods of observing and quantitatively measuring the properties and reactions of chemicals. Included is a brief sketch of course content and requirements. (CC)

This bulletin for the researcher, the doctoral or master's candidate, or teacher interested in and/or conducting research is intended to (1) alert novice investigators to the major requirements and pitfalls of survey and experimental research, (2) point out the weaknesses of past business education studies, and (3) provide consumers of research…

This research investigates stochastic approximation procedures of the Robbins-Monro type. Following a brief introduction to sequential experimentation, attention is focused on formal methods for selecting successive values of a single independent variable. Empirical results obtained through computer simulation are used to compare several formal…

An experiment that proved worthwhile at Lehman College is reported, in which student teams learned how and produced research papers, a requirement in half the courses on the campus. (Editor/PG)

Suggests two uses for the programmable calculator in the freshman chemistry laboratory: as a means of determining whether or not a student's raw data from a laboratory experiment fall within acceptable tolerance limits; and as a means of checking the reliability of unknowns and grading on quantitative experiments. (MLH)

Describes a "feedback course" offered at Brown University, in which undergraduates redesigned the introductory organic chemistry laboratory. The students specified objectives for the ideal lab, then devised laboratory experiments. Laboratory safety was stressed, all dangerous reagents and solvents were eliminated, and toxicological data were…

Designed for first-year students of radiochemistry and atomic physics, this experiment tests the fundamental Moseley Law and introduces the method of elemental chemical analysis by X-ray fluorescence. (Author/MLH)
