Problems in the experimental laboratory in scientific research are discussed and solutions are proposed for the problem of conflicts between the experimental model and reality. As a possible beginning for change, an apparatus is suggested to replace the tachistoscope. (SCC)

Isomeric ketones containing six or seven carbons are separated, illustrating the capability of chemical instrumentation for separating a group of closely related compounds. (MLH)

An operational instrument was designed to approach the tasks of curricular planning and design of university programs in communication in Mexico, or elsewhere in the Third World. The instrument was designed by the Mexican team of advisors at the Workshop-Seminar on Curriculum Planning, held in Villa de Leyva, Colombia, in May of 1987. It was used…

Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Commonly used in map making, real estate zoning, and highway route location, aerial photography planes equipped with multispectral cameras may, among many environmental applications, now be used to locate mineral deposits, define marshland boundaries, study water pollution, and detect diseases in crops and forests. (KM)

Describes the structure and content of the laboratory course sequence of the Engineering College of the State University of New York at Stony Brook. The multidisciplinary laboratory sequence is a core requisite take n in the junior year, and instructs students in experimental methodology, including measurement and instrumentation theory. (JR)

A methodology for developing a teaching effectiveness rating instrument is provided which elicits measures in terms decision makers believe important, avoids redundancy, includes items raters are able to rate (as perceived by decision makers), and includes concerned parties in the development of the instrument. Methodology consists of development…

Identifies a trend in analytical chemistry toward greater use of instruments and a need for an understanding of the basic principles involved in instrumentation. This need can be fulfilled using homebuilt equipment; examples are provided in the areas of electrolytic conductance and electronic coulometry. (GS)

Described is the use of a general purpose hybrid computer in controlling and monitoring certain experiments on human subjects. In these investigations, researchers produce various sensory stimuli and measure participants' responses as voltage produced at a scalp node. The computer system discussed facilitates implementation of these experiments as…

A workable theory of instruction appears to depend upon the development of measurement instruments, which operationally define concepts such as transfer, analysis, synthesis, and evaluation, to make possible empirical investigation of the relationships of methods of instruction and learner variables to the attainment of different types of…

A device called the Student Responder may be used to obtain student responses during programed instruction lectures. In Air Force flying and technical training programs, the device can be used in a dimly-lit or darkened classroom during slide presentations. When multiple-choice questions are projected on the screen, the student responses are…
