Reports on ways in which interactive video-based courseware is being used with students studying for vocational qualifications at Thames Valley University (United Kingdom). Two alternative models using interactive video are described, one using multiple workstations and one using a single workstation led by a tutor. (Contains six references.) (LRW)

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)

Describes science experiments for undergraduate biology instruction on the concepts of mutation and characterization of the resulting mutant strains. The filamentous fungi "Fusarium moniliforme" is used to illustrate the induction of mutants (mutagenesis), identification of the mutated gene, construction of a biochemical pathway, and…

Explains how the tobacco mosaic virus can be used to study virology. Presents facts about the virus, procedures to handle the virus in the laboratory, and four laboratory exercises involving the viruses' survival under inactivating conditions, dilution end point, filterability, and microscopy. (MDH)

Examining living organisms in one's own backyard is a key first step toward appreciating the scope and importance of biological diversity throughout the world. The goals of this lab are to involve students in exploring the biodiversity around them, appreciating its scope, and asking questions of new organisms that they may never have noticed…

Describes InterLabs, a multidisciplinary computer laboratory developed at Bradley University (Illinois). Highlights include student leadership; experience-based learning; examples of work; a new curriculum called Social Informatics that addresses changes in society that follow technology changes; problems with administrative support and funding;…

Describes the development of an innovative, multimedia, interactive CD-ROM aimed at helping teachers tackle the problem that students have with evaluating science laboratory work. (Author/WRM)

Describes an experiment in which students determine the density of Coke and Diet Coke, consider density as an intensive property, and compare the accuracy and precision of different types of glassware. (WRM)

Describes a novel course in first-year undergraduate practical biology that introduces students to the principles and practices of a variety of biological techniques. (CCM)

Describes the history and uses of the coulometer, a device for measuring quantities of electricity. (Contains 27 references.) (Author/WRM)

Presents a series of experiments that can be used to demonstrate how aspirin can be synthesized and characterized, how the hydrolysis of aspirin can be used as an introduction to kinetics, and how coordination chemistry (chelation) can be introduced by preparing and characterizing the copper complexes of aspirin and salicylic acid. (Contains over…

A biotechnologist-turned-teacher introduces a series of laboratory modules incorporating concepts from microbiology, cellular biology, molecular biology, biochemistry, and evolution. The Amylase Project aims to distill the biotechnology process into a few short steps using amylase, the easiest enzyme to detect of those commonly produced by…

Recommends beginning certain chemistry courses with revision and consolidation of mole calculations. Argues that by choosing examples related to health and safety, mole calculations can be made less academic while raising student awareness of important issues. (DDR)

Seven sites are designated as Department of Energy (DOE) National Environmental Research Parks and serve as irreplaceable outdoor laboratories for scientific research and education. The DOE has recommended the disposal of nearly one- quarter of the research park land holdings. Offers suggestions for developing a plan for protecting the…

A study of 723 University of Cape Town (South Africa) physics students investigated their prior experience with laboratory procedures and technical report writing. Results suggest that, although students are generally aware of the importance of these elements of learning, school experience with teaching of scientific concepts and skills is often…
