Explains that the writing center is a computerized tutoring room where high school students can get individualized help with their writing. Describes some of the activities and problems of one such center. Suggests that the center can help students learn to be good writers and become more familiar with computer technology. (SG)

Discusses a microcomputer program that was created to simulate the behavior of a computerized "animal" so that students could practice the shaping of behavior. Describes mathematical algorithms that allowed the "animal" to show gradual improvements in directional movements after appropriate shaping. Reports that students were…

A laboratory experiment designed to provide rapid, inexpensive student exposure to pharmacogenetics in drug elimination and patient therapy is described. The test, performed on students, determines expression of a drug metabolism enzyme following ingestion of a probe drug. (Author/MSE)

This article explains how animals are used in research in an effort to counteract animal rights literature. Reveals how medical professionals and others trained in scholarship have misquoted the scientific literature to bolster their claims against the utility of animal research. (PR)

Describes an assignment and the results of having elementary school students design their own interesting and exciting science classroom environment. (PR)

Antagonism is the production of substances by microorganisms that inhibit or prevent the growth of other bacteria. This paper demonstrates the antagonistic behavior of gram-positive coccus on the B. subtilis and Enterococcus faecalis gram-positive microorganisms, showing that the process of antagonism is sometimes dependent on the nutritional…

Describes a microbial bioassay, using molds as test organisms, that demonstrates toxicities of environmental pollutants. Includes laboratory methods and applications for the experiment. (MDH)

Describes what can be learned from animal dissections and asserts that models and videos cannot substitute for dissections. (PR)

Describes changes to a traditional study of population in yeast colonies. Changes to the procedures include: (1) only one culture per student team; (2) cultures are inoculated only once; and (3) the same tube is sampled daily. (DDR)

Presents some simple demonstrations that students can construct for themselves in class to learn the difference between diffusion and convection rates. Uses cabbage leaves and gelatin and focuses on diffusion in ungelified media, a quantitative diffusion estimate with hydroxyl ions, and a quantitative diffusion estimate with photons. (DDR)

Examines the development of a science center at a college, including the transformation of the physical facility and curricular changes. Provides a sketch of the facility and details about staffing the center. (DDR)

Explains a taxonomy of basic skills of science practicals that is used in the assessment of secondary science students. Details the assessment scheme which involves the evaluation of students through laboratory practical examinations, observational assessment, and written records of academic sessions. (DDR)

Safe science in schools depends on the premise that students and teachers share similar perceptions on issues of safety related to the general level of a student's maturity. Suggests that a divergence rather than a convergence of perception actually occurs. (DDR)

Explores the issue of physics laboratory work for engineering students and discusses the design, implementation, and evaluation of a laboratory program developed for first year engineering students. (DDR)
