This is a critical review of methodological issues in the evaluation of adult literacy education programs in the United States. It addresses the key research questions: What are the appropriate methods for evaluating these programs under given circumstances. It identifies 15 evaluation studies that are representative of a range of adult literacy…

The purpose of this study was to empirically test the hypothesis that students who participated in a contextualized, mathematics-enhanced high school agricultural power and technology curriculum and aligned instructional approach would not experience significant diminishment in acquisition of technical skills related to agricultural power and…

Food and nutrition affect the course in physical development that our bodies will follow. Our emotional make-up and mental behavior may be influenced by diet, but the direct relationship between these aspects of development and nutrition needs further study. A new research approach is described. (Author/RH)

Argues that more attention should be given to the specification of the independent and dependent variables which describe, explain and predict intraindividual stability and change over time. Statistical techniques for such study are briefly discussed. (Author/SDH)

A procedure for testing heterogeneity of variance is developed which generalizes readily to complex, multi-factor experimental designs. Monte Carlo studies indicate that the Z-variance test statistic presented here yields results equivalent to other familiar tests for heterogeneity of variance in simple one-way designs where comparisons are…

The use of multiple regression as a data-analytic tool is examined for the cases of balanced and unbalanced designs. The utility of this method for testing specific contrasts, both orthogonal and nonorthogonal is discussed and some interpretive cautions are examined. (Author)

Designs for sequential sampling procedures that adapt to cumulative information are discussed. A familiar illustration is the play-the-winner rule in which there are two treatments; after a random start, the same treatment is continued as long as each successive subject registers a success. When a failure occurs, the other treatment is used until…

Phenomenological research is defined and discussed in terms of its purpose and procedures. Phenomenology deals with subjective consciousness. Phenomenological research probes into the human experience to illuminate the complexity of individual perception. It is aimed at interpretive understanding. The general design for research consists of three…

In this paper the role of qualitative research in special education is examined. The implications of an earlier naturalistic study are cited, an important one being the tendency in the literature to oversimplify the naturalistic paradigm; and the case is made that implementing such a paradigm is a "labor intensive" approach to research…

Attempts to account for discrepancies between results of the Hall and Kingsley experiment (1968), (in which the majority of college students did not resist extinction in a contrived instance of non-conservation of weight), and the Miller, Schwartz and Stewart experiment (1973), (in which the majority did resist extinction).
