A population data set was randomly generated from which a random sample was drawn. This sample was randomly divided into two data sets, one of which was used to generate parameter estimates, which were then used in the second data set for cross-validation purposes. The best variable subset models were compared between the two data sets on the…

This paper contributes to an emerging rational reconstruction of the concept of educational leadership in a critical theory (or method) of education. This partly accomplished task is extended by appropriating and analyzing the social philosophy of Jurgen Habermas. In particular, the theory of communicative action and the notion of the ideal speech…

This paper presents and discusses a conceptual model for understanding, describing, and explaining personnel selection processes and activities. Four theoretical strands--decision theory, impression formation, inference theory, and rating theory--are briefly discussed and woven together as the basis for the proposed model. The model is then used…

This document presents a first approximation for a model for student performance in solving linear equations. First, characteristics of a model of student performance for solving linear equations is discussed. It is noted that there is a need for some theoretical structure to support and organize the bits and pieces of information provided by…

A cogent model of self concept may provide educators with the tools to predict and induce change in the classroom behavior of students. The nature of measurement operations, management operations and particularly, the relationship between self concept and behavior are delineated. Discussion focuses on how such behaviors are acquired, manifested…

Over 40 papers presented at an Australian conference on curriculum evaluation are included in this publication. Among the topics are: evaluation models; the relationship of reliability to the amount of observation; Elementary Secondary Education Act Title I evaluation; designing policy-oriented research; methodology in evaluating teacher behavior;…

This document is part of a series of chapters described in SO 011 759. Addressing the problems of studying change and the change process, the report argues that sociologists should study coupled changes in qualitative and quantitative outcomes (e.g., marital status and earnings). The author presents a model for sociological studies of change in…

This document is part of a series of chapters described in SO 011 759. The chapter examines the merits of four estimators in the causal analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable). The four procedures are ordinary least squares, Kaplan-Meier least squares, maximum…

This inquiry was conducted to develop indigenous research methodology aimed at minimizing the gap between educational research and practice. The intent was not to produce a final or complete solution to the problem, but rather to suggest a procedure which would provide partial closure. Alternative methods, including various types of linkage…

Requirements of research projects intended to evaluate the cost-effectiveness of new or modified health-care-delivery arrangements are discussed. Included in the discussion are the peculiarities of evaluation research, issues that arise in the implementation of health-related programs and their evaluation, and the dissemination process. (JMD)

Identified are four major fallacies in Douglas Fuchs and Lynn Fuchs' critique of the Adaptive Learning Environments Model (ALEM) and the General Education Initiative (GEI): erroneous interpretations of the GEI, segregationism in the Fuchs' point of view, the research base of the ALEM, and readiness for the GEI. (JDD)

This paper refutes the arguments of Margaret Wang and Herbert Walberg in their support of the Adaptive Learning Environments Model (ALEM) and the General Education Initiative. It focuses on the small number of ALEM implementations and replications, weaknesses of the research and evaluations supporting ALEM, and other specific criticisms. (JDD)

Points out that infant day care research is still in its infancy, criticizes Jay Belsky's infant day care position conceptually and methodologically, and considers alternative models of influence that may account for the putative association of day care and maladjustment. (SKC)

Considers possible contributions of developmental psychology to analysis and solution of practical problems by proposing a practical action model comprising the following: nature of the phenomenon or problem; existence of the phenomenon or problem; outcome in case of no intervention; goals for intervention; achievement of goals; and assessing…

In the study, a part of longitudinal research focused on the emergence of mathematical knowledge structures in a learner's mind is presented. It concentrates on the analysis of introspective data gained from the author's study of a non-standard arithmetic structure in terms of the model of abstraction in context (Hershkowitz, Schwarz and Dreyfus).…
