As with any new theory, it is necessary to validate the basic construct of vocational maturity. Once this is done, instruments to measure vocational maturity, or decision making, can be evaluated. With this as an objective, this paper discusses some of the problems associated with measuring vocational maturity, such as identifying variables,…

The need for competent formal evaluation programs, particularly for new federally assisted programs, is expressed. Problems in defining educational evaluation and its requirements, in designing such evaluations, and 3 possible sources of faulty conceptual bases for evaluations, are presented. An attempt is made to define evaluation in general, to…

The relative power of three possible experimental designs under the condition that data is to be analyzed by nonparametric techniques; the comparison of the power of each nonparametric technique to its parametric analogue; and the comparison of relative powers using nonparametric and parametric techniques are discussed. The three nonparametric…

The objectives of this study were: (1) to identify the middle and upper-middle class urban audience in terms of certain selected variables; (2) to design and perfect techniques to measure attitude toward and knowledge of pesticides and chemicals; (3) to determine the present knowledge and attitude of the audience toward pesticides and chemicals;…

Suggested is a learning systems approach designed to be consistent with the objectives and scope of developmental psychology and yet sophisticated and appropriate enough to fit the unique demands of early childhood education. Identified are eight contingencies for learning that any educational system must possess. Added to these are features…

This paper examines interaction in a school class through the factor-analytical P-technique, considers the behavior of the factor scores in combination with certain other variables included in the interaction matrix, explores the formation of homogeneous groups of lessons in a grouping analysis based on the factor scores, and compares this latter…

This study examines quantification of the instructional process through the use of Markov chaining, and by considering the transition probabilities within a framework provided by the taxonomy used, attempts to obtain information about behavior sequences common to all lessons. (Author/DLG)

Matching, randomization, random sampling, and other methods of controlling extraneous variation are discussed. The purpose was to specify the benefits of randomization in estimating causal effects of treatments. It is concluded that randomization should be employed whenever possible, but the use of carefully controlled nonrandomized data to…

By and large behavioral scientists, particularly in education and psychology lack the sophisticated mathematical understanding necessary for adequate statistical analysis, especially multivariate analysis. And incompetent use of measurement theory, psychometry, and statistics cannot but lead to bad research. The remedy for this is better…

Phase II of the Beginning Teacher Evaluation Study was designed to provide data relevant to policies that might be developed for teacher preparation and licensing. A portion of the data from Phase II is used to illustrate how the research was designed to answer these policy questions and how the data implies provisional answers to them. To answer…

This document is the fourth and final report of a study sponsored by the Office of Child Development of the U.S. Department of Health, Education and Welfare to determine patterns of child care usage and related consumer preferences, attitudes and opinions about child care. The study was based on 4609 personal interviews conducted in 1975 from a…

Student's empirical sampling approach is used to assess the magnitude of the sampling errors of statistics describing a recursive causal model. The data were gathered with four complex sample designs commonly used in educational surveys. Jackknife and half-sample error estimates are applied to the data. (Author/CTM)

Social science research does not fit well, either in its execution or in its results, with the organizational structure and the time requirements for decision making in the federal administrative system. Different organization of research for procedural questions and policy issues could eliminate this ill-timing. (Author/KR)

After offering some possible explanations for the existing inadequacies in evaluating organizational training programs, the authors discuss several evaluation issues, particularly internal validity. Methods for overcoming evaluation inadequacies and the implications for better controlled evaluation designs are also covered. (EM)
