The language skills category of objectives of the Appalachia Preschool Education Program as measured by the Illinois Test of Psycholinguistic Abilities (ITPA), is discussed. The point is made that one of the difficulties associated with evaluating language development is the loose fit between available theoretical and operational definitions of…

It is the purpose of this paper to suggest the orthogonal analysis of variance as a device for simplifying either the analytic or iterative problem of finding LS (least squares) estimates for the parameters of particular nonlinear models. (Author/RK)

Logically consistent hypothesis-testing for factorial analysis of variance designs is proposed in the context of a hierarchical model. It is shown that all of the hypotheses associated with the traditional factorial model are conceptually independent and occupy the lowest levels of the hierarchy. (Author/JKS)

This paper deals with the situation where scores on a number of parallel tests are obtained for each of a set of persons, and these persons are assumed to constitute, in so far as their scores for the tests are concerned, a random sample from some population of interest. (Author)

Variance reduction analysis is a simple method for determining the effect of inequality of cell size on analysis of variance calculations. The suggested procedure has three steps. (Author/CK)

The results of an extensive analysis of the statistical methodology employed by researchers whose manuscripts were published in the first twelve volumes of the "Educational Administration Quarterly" are reported. (Author)

In a nonmetric multiple-cue probability learning task involving 2 binary cue dimensions, it was found that Ss can learn to use configural or pattern information (a) when only the configural information is relevant, and in addition to the configural information, one or both of the cue dimensions are relevant. (Author/RK)

This volume contains the five major addresses and subsequent discussion from the Symposium on the General Linear Models Approach to the Analysis of Experimental Data in Educational Research, which was held in 1967 in Athens, Georgia. The symposium was designed to produce systematic information, including new methodology, for dissemination to the…

The particular concern of this experiment was to develop a technique for the effective study of the factors that influence the buildup of proactive inhibition in short-term memory studies of the Brown-Peterson variety. (Author)

Although the evaluation of innovations in teacher training is often dependent on observational data, the problem of the reliability of the observations collected by a team of observers has often been treated in a superficial manner, partially because of the difficulties of maintaining an observer team intact over an extended period of time and of…

Analysis of current models describing citer motivations identified seven most significant motivations for authors: currency scale, negative credit, operational information, persuasiveness, positive credit, reader alert, social consensus. Motivational background for more than 900 citational acts of 26 authors at University of Iowa were gathered and…

Second-, fourth-, and sixth-grade children were tested on a multiple-classification task to investigate the relationship between age and observational learning. (Editor)

The present study used a naturalistic setting to determine the effects on children of modeled sex-inappropriate play behaviour. (Author)

The present experiment was designed to give attention to a potentially important parameter, that of paired-associate task modality. (Author/RK)

A model's influence on the creative behavior of 120 fifth-grade children was studied in four variations. (Author)
