Describes an interdisciplinary assignment involving biology and English in an introductory-level course. Presents information on a general description of the assignment, a workshop on plagiarism and organization, and evaluation. Cites six points that must be stressed in a discussion of paraphrasing. (RT)

Studies the pressure and energy of particles interacting through a Lennard-Jones potential and correlates thermodynamical properties with system structural characteristics. Analyzes the relationships between computer simulated data and the van der Waals equation. (YP)

Explores neurochemical events in the extra cellular space of the brain by use of in vivo voltammetric microelectrodes. Reports dopamine concentrations and pathways, and discusses techniques used for analysis. Recognizes current problems and future directions for research. (ML)

Compares different views of the role of sexual reproduction concerning the survival and evolution of species. Discusses the benefits and disadvantages of thelytoky, one nontraditional method of reproduction. (CW)

Presents an overview of 15 laboratory exercises used in an experimental ecology laboratory. Stresses that these exercises require no field work by students and are geared toward testing hypotheses. Suggests the use of these exercises in high school as well as college. (CW)

Reports on a symposium on reforming general chemistry curriculum sponsored by American Chemical Society's Education Division. Presents several discussions including levels of the goals of general chemistry, newly recommended content, and the pros and cons of descriptive chemistry. (YP)

Describes an example of the main steps in restructuring a curriculum and thinking developed by a systems approach. Provides several diagrams illustrating the curriculum structure. (Author/YP)

Develops an experimental teaching method emphasizing the nature of functions including graphical representation in an introductory college physics course (mechanics). Examines the effects of this method on student's problem solving and attitude toward physics. (YP)

Describes a three-dimensional computer aided design software package, CADKEY, for demonstrating orthographic orthodirectional projection theory to a classroom. Provides several figures for showing the demonstrations. (Author/YP)

Discussed are medical applications of ultrasound. The physics of the wave nature of ultrasound including its propagation and production, return by the body, spatial and contrast resolution, attenuation, image formation using pulsed echo ultrasound techniques, measurement of velocity and duplex scanning are described. (YP)

Described are the purposes, laboratory set-ups, and procedures of four classroom experiments: ultrasound speedometer; vibrating-bar depth gauge; folding three-dimensional model of equipotential surfaces; and a simple optical system for the reconstruction of images from computer-generated holograms. Diagrams and pictures are provided. (YP)

Supercomputing is described in terms of computing power and abilities. The increase in availability of supercomputers for use in chemical calculations and modeling are reported. Efforts of the National Science Foundation and Cray Research are highlighted. (CW)

Described is a teacher education program organized by the Sea Education Association in Woods Hole (Massachusetts). The experience, including activities and examples of studies conducted, is discussed. Contact information for future cruises is included. (CW)

A computer assisted technology training program is described. Technological literacy is defined. A course list for the program and a programing model are provided. (CW)

Discusses four problems which concern engineering education in developing countries: (1) less value of handiwork; (2) lack of industrial culture; (3) low salary of faculty; and (4) cultural distortions. Describes three successful cases in Indonesia and Thailand. (YP)
