The Peabody Picture Vocabulary Test is marketed as an instrument suitable for use by persons without special training in testing. A total of forty children, ranging from retarded to gifted, were tested in counter-balanced order by eight elementary school teachers and by three school psychologists. (Editor)

The aim of these pages is to provide some perspective on Project Zero's recent work, updating earlier accounts which have appeared in the Journal of Aesthetic Education and elsewhere. (Author)

Describes the Alum Rock voucher experiment concluding that the voucher system represents a profound structural change. Parents and students have expressed great satisfaction; pupil achievement was probably down during the first year -- but up during the second. An income-outgo budgeting system has been developed which may be the most equitable…

A look at an experiment carried out by the University of Pittsburg, dealing with citizen access of commercial television time. (HB)

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…

Article evaluated the merits of the practical test, regarded as a valuable one for measuring aspects of science achievement other than the aspects measured by paper-and-pencil type tests. (Author/RK)

In a previous paper (Hartley and Holt, 1971) the development of a three-minute reasoning test was described, and its validity and reliability assessed. In this paper three experiments are reported which look in greater detail at these aspects of the test in different situations. (Author)

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)

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