A study of 1127 classes of 7-, 9-, and 11-year-old children in English schools was conducted to obtain information about the organization of schools, the range of work done by children, their performance on certain tests, and the degree to which children's work is matched to their abilities.

A simple example is presented that illustrates advantages of Bayesian and likelihood methods of inference relative to sampling distribution methods of inference. It is argued that Bayesian and likelihood methods of inference should be utilized more generally to analyze real data. (Author/CTM)

Problems in avoiding the singularity problem in analyzing matrices for optimal scaling are addressed. Conditions are given under which the stationary points and values of a ratio of quadratic forms in two singular matrices can be obtained by a series of simple matrix operations. (Author/JKS)

The multiplicative correction term for the degrees of freedom in a repeated measures analysis of variance table is given for the cases in which there is equal variability per time point, and the correlation between observations is k time units apart. This correction equals the correlation coefficient raised to the kth power. (JKS)

Two least squares procedures for symmetrization of a conditional proximity matrix are derived. The solutions provide multiplicative constants for scaling the rows or columns of the matrix to maximize symmetry. (Author/JKS)

G analysis is a data analytic method based on the G index of agreement. A generalized technique for the rotation of factors in G analysis in which marker variables are brought into alignment with their adjoining reference axis is presented. (Author/JKS)

A set of tables for determining tetrachoric correlations is presented. The coefficients have been determined to three-decimal accuracy. (JKS)

Stochastic approximation is suggested as a useful technique in areas where individuals have a goal firmly in mind, but lack sufficient knowledge to design an efficient, more traditional experiment. One potential area of application for stochastic approximation is that of formative evaluation. (CTM)

Presents opening address and a presentation concerning the problems and possibilities of science education--both presented at a Conference of the Science Teachers of Australia. (MLH)

Discusses the need to provide evidence when making claims, particularly when reporting research results. Suggests evidence should be precise; be wary of generalizations; question authority; and link the manuscript together in a coherent manner. (LRW)

Identifies deficiencies in the new edition of the American Psychological Association's "Publication Manual," drawing on interviews with some critics and other parties. These include lack of follow-through with explanations and examples of how to report the statistics now recommended. (SLD)

Study analyzed associations between pubertal timing, sexual activity, and self-reported depression in sample of girls and boys aged 14-16. Among girls, self-reported depression was associated with early puberty and intimate sexual relationship. Among boys, depression was associated with every early and late puberty and experience of intercourse.…

Describes how Geographic Information Systems (GIS) can be used to help evaluators convey complex information simply through a spatial representation. Demonstrates how GIS can be used to plot change over time, including impact and outcome data gathered by primary data collection. (SLD)

Asserts that experimental research articles are "explanatory minihistories," of reading containing elements of prescription, description, and prediction found in most histories. Argues that reading historians will have to select from among these minihistories to arrive at an explanatory history of the reading field. (MM)

Twenty-five doctoral dissertations completed in 1993 and addressing aspects of deafness and hearing impairments are listed. Provided are title, author, university, number of pages, location of abstract, and order number. (DB)
