Describes how to construct an inexpensive condenser to be used in a fractional distillation demonstration. (BR)

The results of a process of designing, building, and "de-bugging" two replacement language laboratory hardware systems at Concordia University (Montreal) are described. Because commercially available systems did not meet specifications within budgetary constraints, the systems were built by the university technical department. The systems replaced…

Describes an introductory lecture-demonstration for a physics class. The device transports a small steel ball from a starting point to a finishing point; along the way the ball goes through a number of steps. (RH)

A light flasher was developed for use with the open-shutter photography technique in elementary-mechanics experiments. Details are given of its design and construction. Five experiments, for the elementary mechanics laboratory, which use flasher units are described. (DT)

Examines the ways in which different forms of interpreting can be practiced in the language laboratory, and implications for teaching strategies and laboratory design. (AM)

Describes and discusses an arrangement of laboratory equipment by means of which small groups may converse with each other and with the teacher without interfering with other groups working in the same laboratory. Includes schematic diagram. (Text is in German.) (IFS/WGA)
