The computer assisted instruction (CAI) program at the California School for the Deaf, at Fremont, features individual Apple computers in classrooms as well as in CAI labs. When the whole class uses computers simultaneously, the teacher can help individuals, identify group weaknesses, note needs of the materials, and help develop additional CAI…

Signal-Detection theory was applied to analysis of automatic data. In one experiment, anxiety surrounding auditory signals was induced; in the other, signals were administered to a psychometrically anxious group. Subjects in both experiments had enhanced automatic activity. (Author/CS)

A review of experiments which demonstrate the release of ATP from skeletal muscle, cardiac muscle, and active brain tissue. Effects of exogenously applied ATP to brain tissue are discussed in relation to whole body exercise. (Author/SA)

A review of the fundamentals of hazardous chemical safety with specific emphasis on flammable liquids, corrosive chemicals, insidious hazards, compressed gases, and cryogenic liquids. (Author/BB)

A description is given of a project investigating the use of an interactive learning system in introductory college chemistry courses. (MP)

Provides background leading to a reorganization of the environmental health and safety program at the University of Florida; describes the reorganized program, and discusses experiences from the first year of operation. (MLH)

Describes an experiment to demonstrate Boyle's law that provides pressure measurements in a familiar unit (psi) and makes no assumptions concerning atmospheric pressure. Items needed include bathroom scales and a 60-ml syringe, castor oil, disposable 3-ml syringe and needle, modeling clay, pliers, and a wooden block. Commercial devices use a…

Miles Pickering joined the Princeton University staff in 1976, became director of the undergraduate chemistry laboratories in 1981, and was a chemistry department lecturer and senior staff member until he died in 1991. Focuses on his inspiring publications in the "Journal of College Science Teaching" and the "Journal of Chemical Education."…

Describes the construction of an insulated wooden wall incubator that combines excellent temperature control over the usual operating range with easy electrical access, low cost, and a wide potential size range. Presents a temperature- monitoring circuit, designed to measure the small temperature variations within the incubator, which could…

Indicates a desire and need to construct an elaborately detailed and historiographically sophisticated model that would effectively account for the complexity of writing center development and history. Critically examines two models currently in use, the "evolutionary" model and the "dialectic" model. Offers a cultural model of writing center…

Describes how a handful of institutions are experimenting with computer simulations to offer hard science labs through distance education. (EV)

Reports the results of a National Science Teachers Association (NSTA) study that analyzed science classroom safety. Examines the potential need for a national safety indexing system to rank states with regard to science safety. (DDR)

Argues that humor serves a critical ethos function in online communities created by mailing lists. Connects what humor theorists already recognize as a social dimension in joking to the contemporary interpretation of ethos as a constitutive force. Applies the model to the rhetoric of a university writing center mailing list. (SG)

Presents science activities conducted with liquid nitrogen to demonstrate electricity, magnetism, and kinetic theory. (YDS)

Discusses clinical trials in general, protecting human research subjects, and the role the research administrator can play in facilitating the process. The discussion is not intended to be a thorough treatise on clinical trials, but is an overview of new and lesser known human protection issues that are better handled prospectively. (EV)
