A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)

Describes science-related competitive events in which 10th and 11th grade students participated. The organization and operation of the olympiad is detailed. (CP)

Topics in biology A-level projects are briefly described. (CP)

Studies the effects of computer-managed self-paced (CMSP) and teacher-managed group-paced (TMGP) laboratory instruction on the attitudes toward science of ninth-grade students. All students were enrolled in an introduction to chemistry and physics course. Posttests revealed that groups did not differ significantly on achievement measures but the…

Listed and described are student A-level biology projects in the following areas: Angiosperm studies (e.g., factors affecting growth of various plants), 7; Bacterial studies, 1; Insect studies, 2; Fish studies, 1; Mammal studies, 1; Human studies, 1; Synecology studies, 2; Environmental studies, 2; and Enzyme studies, 1. (CS)

Presents a history of Dartington, a small arts college in England, from 1934 to the present. Topics include schools of music and art which influenced Dartington, college founders, educational objectives, staff, new academic structures, career awareness, degree requirements, success factors, and student attitudes. (Author/DB)

Five experiments were conducted comparing performance on paired-associate lists of stimuli that rhymed with lists of stimuli that did not rhyme. Results are discussed in terms of the role of input position cues in aiding discrimination among items. (Editor/RK)

Seven experiments are described investigating the effecy of high intensity white noise during the visual presentation of words on a number of short-term memory tasks. Examines results relative to position learning and sequence learning. (Editor/RK)

Results of this experiment indicate that negative first impressions of a teacher have a significant effect upon the classroom climate. (RW)

Describes an experiment which demonstrates the association of particular metabolic biochemical changes and muscular fatigue. Highlights applications related to cellular energy metabolism, metabolic regulation, and muscle energetics. (ML)

Discusses the use of thin-layer chromatography (TLC) in the chemical laboratory as a quantitative method for determining the molecular weights of organic compounds. Describes a simple method which provides an illustration of the importance of polarity on solubility and demonstrates the effectiveness of TLC as a quantitative tool. (TW)

Research results in the social and behavioral sciences are thought to be less replicable than results in the physical sciences. Comparisons of the cumulativeness of research in the former sciences have not been made. Argues that the study of cumulativeness could predict results from replicated experiments under good conditions. (Author/VM)

Describes a simple undergraduate experiment in chemistry dealing with the "solvent effects" in nuclear magnetic resonance (NMR) spectroscopy. Stresses the importance of having students learn NMR spectroscopy as a tool in analytical chemistry. (TW)

Describes three situations in which computer software was used in a chemistry laboratory. Discusses interfacing voltage output instruments with Apple II computers and using spreadsheet programs to simulate gas chromatography and analysis of kinetic data. Includes information concerning procedures, hardware, and software used in each situation. (CW)

Presents a laboratory exercise suitable for advanced placement biology or chemistry classes. Discusses the theoretical approach, preparation and standardization of reagents, and results. Emphasizes standard analytical procedure and chelometric titration. (CW)
