This study evaluated the applicability of the averaging model of the information integration theory to attitude formation in a classroom situation and compared the results of an in-classroom and an in-laboratory application of equivalent stimuli (verbal vs printed). Results confirmed both the information integration theory and the averaging model.…

A laboratory experiment compared the relative effects of observing and participating in a first Prisoner's Dilemma Game (PDG) on subsequent PDG encounters by the original observer and participant. Concludes that vicarious experience is superior to direct experience in producing responses that reduce interpersonal conflict. Available from: Sage…

Provides background information on polymeric films and membranes including production methods, special industrial and medical applications, laboratory preparation, and an experimental investigation of a porous cellulose acetate membrane. Presents a demonstration to distinguish between high- and low-density polyethylene. (JM)

Describes an experimental program to examine flow curve determination for non-Newtonian fluids. Includes apparatus used (a modification of Walawender and Chen's set-up, but using a 50cc buret connected to a glass capillary through a Tygon tube), theoretical information, procedures, and typical results obtained. (JN)

Examines views, attitudes and feelings of high school pupils about their school science practicals (labs) via letter-writing and picture-drawing. Concludes that while students generally like practicals, they view them more as a means of confirming theory rather than an open investigation or true experiment. (JDH)

This article describes a program of laboratory and field research on broadcast teletext. In addition to presenting major results and summarizing their implications, it sets the program within the context defined by stakeholders in the teletext field. It also reviews the methodological issues and practical eventualities that shaped the research.…

Describes a combustion laboratory facility and experiments for a senior-level (undergraduate) course in mechanical engineering. The experiment reinforces basic thermodynamic concepts and provides many students with their first opportunity to work with a combustion system. (DH)

A Commodore-64 microcomputer was used to develop a system which is useful for a variety of teaching laboratory and real time control applications. Hardware and software requirements and examples of experimental work with the system are provided. (JN)

A general laboratory course featuring microcomputer interfacing for data acquisition, process control and automation, and robotics was developed at Rensselaer Polytechnic Institute and is now available to all junior engineering students. The development and features of the course are described. (JN)

Describes a semester-long project in which students designed, built, and operated an apparatus to separate particles by fluidization principles. Each laboratory group worked on a separate step of the design in a sequence selected by the instructor in a manner similar to the way a design team might function. (JN)

Described is an exercise involving the measurement of temperature in a peripheral tissue, brown adipose, that is readily accessible in the laboratory rat. (RM)

Describes a drying experiment useful in presenting the concept of simultaneous heat and mass transfer. Background information, equipment requirements, experimental procedures, and results are provided. The reasonably good agreement in the calculated rate of drying and that observed experimentally makes students feel confident in applying…

Describes an undergraduate physical chemistry experiment in phase equilibria which equilibrates potassium iodide solutions of known concentration with solid iodine. (MLH)

Describes a procedure for studying the kinetics of the second-order hydrolysis of ethylene bromohydrine in alkaline medium by incorporating a substance that changes color as one of the reacting components is depleted. (MLH)
