The first half of this article examines the function of various types of language laboratories. They are classified principally as: (1) audio-passive, (2) audio-active, and (3) audio-evaluative laboratories. A chart illustrating the major types of technical installations and their components further classifies laboratories in terms of whether they…

Concepts pertaining to the language laboratory are clarified for the layman unfamiliar with recent educational developments in foreign language instruction. These include discussion of: (1) language laboratory components and functions, (2) techniques used in the laboratory, (3) new linguistic methods, (4) laboratory exercises, (5) traditional…

This paper describes a teaching method, presently in the experimental stage, that advocates the use of a programed instruction model in the language laboratory, with students working in homogeneous groups of three. The author describes the technical construction and operation of the language laboratory which allows three students to work together…

Introduces three different techniques to facilitate the measurement of speed and the associated kinematics and dynamics using a computer. Discusses sensing techniques using optical or ultrasonic sensors, interfacing with a computer, software routines for the interfaces, and other applications. Provides circuit diagrams, pictures, and a program to…

Describes two recently completed projects at Utah State University which have provided marked improvement to the preparation of prospective secondary science teachers. The projects focused on cognitive psychology and conceptual change teaching and construction and furnishing of a new secondary science teacher preparation laboratory. (LZ)

For those in Composition Studies, Kenneth Brufee's social constructionist notion of collaboration has been touted as a panacea for all educational ills. Andrea Lunsford and Art Young have recently endorsed a social constructionist philosophy for writing centers. Lunsford asserts that the best collaborative model is socially constructed and aims…

The methods and materials used in a language lab (LL) are analyzed. The theoretical advantages of the LL are enumerated, including its ability to provide a variety of programs and activities and its provision of an opportunity for students to listen critically to their voices. In order to determine if these advantages are being used, a set of…
