Describes the development and organization of a course begun in 1962 consisting of a sequence of manipulative learning operations. The laboratory operations of Quantitative Physical Science lead the student through the fundamentals of instrumentation and of measurement processes. Principles studied include physical, electrical, chemical, and wave…

Discusses the feasilility of the use of repeater devices in the language laboratory in order to enable the student to "recapitulate effortlessly and and indefinitely any utterance of any length which is causing him difficulty or is of special interest. (FWB)

Based on a paper presented at a meeting of the National Association of Language Laboratory Directors.

Discusses and lists, in table form, the specifications and characteristics of 28 low-cost digital multimeters, including jacks, number of V ranges, max V, cost, approximate percent accuracy, current scales, display, battery life, volume, and manufacturers. Quality of construction, ease of repair, and similar characteristics not reported. (SK)

Decline in research emphasis in universities is tied to a number of factors: defensive apathy in the university scientific community; weakening links between teaching and research; declining enrollments; problems in interdisciplinary work; employment stability and aging faculty, obsolete equipment, support staff reduction, and growing bureaucracy.…

Describes a laboratory scale reactor that determines the kinetics of a gas-solid catalytic reaction. The external recycle reactor construction is detailed with accompanying diagrams. Experimental details, application of the reactor to CO oxidation kinetics, interphase gradients, and intraphase gradients are discussed. (CS)

Describes the computer system and potentiometric titration as a simple experiment to illustrate several advantages and pitfalls in using the small computer in laboratory instruction. (Author/JN)

Describes problems using the Jenkins and White approach and standard diffraction theory when dealing with the topic of finite conjugate, point-source resolution and how they may be resolved using the relatively obscure Abbe's sine theorem. (JN)

Discusses housing facilities for living animals in the classroom or laboratory. The construction of animal cages from materials obtained locally is described. Space recommendations for laboratory animals and cages are also included. (HM)

Describes the latest stage in the design of an economical dielectric constant cell, tested in both instructional and research applications, that is suitable for student laboratories and for precision research measurements. (BT)

Discusses the use of compact cassettes in the context of individualized foreign language teaching in laboratory work at the university level. Presents and comments on some technical data regarding the relative merits of cassettes v reels. (IFS/WGA)

Instructions for making a simple respirometer, to measure rates of oxygen consumption of organisms, are presented. The instrument incorporates most of the basic elements of commercial respirometers but can be made inexpensively by high school students. Operating instructions and applications are given. (Author/SA)

An ebullioscopic apparatus is described in which only the difference between the boiling point of the solution and that of the pure solvent is measured. This substantially reduces the cost of the apparatus and simplifies the operation, while maintaining precision. (BB)

Presented are problems related to replacement and purchasing complex laboratory instruments necessary in biological research. Increased costs of equipment and leveling of research support are acknowledged as contributors to the problem. (SA)
