The sequence of events preceding the actual discovery of oxygen is reviewed; the circumstances surrounding the discovery and isolation of oxygen by Priestley are examined; and the experiments he carried out are described largely in his own words, taken from his books and papers. (DT)

Inadequacies of the traditional curriculum involving laboratory exercises are reviewed; general features of an integrated laboratory program are described. (DT)

At Mountain Empire Community College in Big Stone Gap, Virginia, five busses are being utilized to transport students to and from college, while at the same time providing the equipment and materials needed to permit students to pursue their regular course objectives while traveling. (Author/PG)

With proper staffing, residence halls can be learning laboratories for developing academic and interpersonal competence as well as social effectiveness, as those at the University of Florida illustrate. (Editor)

Describes the construction of an apparatus to produce a stream of water drops of variable size and number of drops per second. (SLH)

Describes a chemiluminescence system which can be used to demonstrate the effects of certain factors which affect the rate of reaction (temperature, concentration, catalysis, solvent, etc.), and to perform experiments relevant to the mechanism of the system. (SLH)

Describes a technique which enables the student to observe the relativistic behavior of electrons in a gamma ray detector and compare his results with the classical and relativistic predictions. Shows that it is possible to unambiguously determine the electron's momentum by knowing the Compton edge and photopeak energies of a gamma ray energy…

Second grade children, divided into high and low achievement groups, were tested on a visual vigilance task in which stimuli occurred 24 times in 30 minutes. High achievers responded correctly more often. (ST)

An automated technique which included an answering time delay, audio-visual tutoring, and extrinsic reinforcement, attempted to change the conceptual tempo of sixth grade disadvantaged children. Results indicate the children did become more reflective in their thinking and responding. (ST)

Children's avoidance responses were conditioned and then extinguished in a laboratory analog of a social threat situation. (DP)

Reviews past and current opinions about the role of the language laboratory. Challenges facing the language learning director and teacher, which encompass innovative testing and humanizing the laboratory, are discussed. (RM)
