Skill learning was studied in 247 elementary and high school students, using a pursuit rotor. Data were analyzed by repeated-measures ANOVA. (ST)

The effectiveness of three fading and two nonfading procedures were compared in training kindergarten children on an oddity problem in which shape was the relevant dimension. (SBT)

Describes the structure and content of the laboratory course sequence of the Engineering College of the State University of New York at Stony Brook. The multidisciplinary laboratory sequence is a core requisite take n in the junior year, and instructs students in experimental methodology, including measurement and instrumentation theory. (JR)

Presents some materials for use in demonstration and experimentation of corrosion processes, including corrosion stimulation and inhibition. Indicates that basic concepts of electrochemistry, crystal structure, and kinetics can be extended to practical chemistry through corrosion explanation. (CC)

Presents the results of educational experiments aimed at incorporating APL programming techniques in an undergraduate physical-analytical laboratory course. Included are a list of first year experiments and some examples of operations. (CC)

This manual provides the waste stabilization pond operator with the basics necessary for the treatment of wastewater in stabilization ponds. The material is organized as a comprehensive guide that follows the normal operation and maintenance procedures from the time the wastewater enters the left station until it leaves the pond. A comprehensive…

The purpose of this study was to determine significant differences in the self-ratings of counseling practicum students, their supervisor, and practicum assistants using the Counselor Evaluation Rating Scale (CERS). Findings indicated significant differences for 9 of the 27 items on the instrument. (Author)

Describes an experiment in which a 500-A-thick silver film is evaporated on the hypotenuse face of a right glass prism. The surface plasmon mode in the film is excited with a He-Ne laser. The dispersion relation for the surface plasmon and the reflectivity due to the excitation of this mode are calculated. (Author/MLH)

Stefan's law is demonstrated by measuring the temperature of the tungsten filament of an electric light bulb and plotting a log-log graph of temperature against power dissipation. (MLH)

Describes two new microscopes, the acoustic microscope and a scanning transmission microscope, both of which promise to yield fresh insights, based on revolutionary techniques into cellular biology. (BR)
