Discusses factor analysis using Rummel's 26-item checklist of essential information that ought to be presented in the published report of a factor analytic study as a guideline for reviewing relevant articles. (JEG)

Provided are explanations of how research works, different approaches to research (naturalistic observation, correctional analysis, the experiment method, the theoretic and compendium approaches), and some of the problems inherent in research methodology in an attempt to encourage practitioners in the field of blindness to use and engage in…

The authors respond to Winograd's critique (TM 503 198) of their previous article on the contributions of artificial intelligence to the scientific study of language (EJ 161 384). Winograd's interpretations of the "Chomskian paradigm," and of statements made in Dresher and Hornstein's original paper, are challenged. (GDC)

The nature of experimental designs in the evaluation of educational programs is addressed in this commentary on the evaluation of the Emergency School Aid Act and a paper detailing that evaluation (TM 503 672). (JKS)

This study tests the hypothesis that perceived freedom is a function of the probability that actors will behave in a line with their dispositions by varying the pattern of extrinsic rewards associated with the behavior alternatives. Subjects in both experiments are college students. (CM)

The author describes her struggles with the issues involved in doing intensive life history research. She was investigating the process of maturation of children who grew up in the San Francisco public housing projects and were able to develop sufficient psychological strength to avoid common problems of project life.

The most important feature of science is that of controlled observations. There is a need for using multiple measures gathered in multiple ways from multiple sources. The intensive study of one or a few cases is a research strategy ideally suited for practicing counselors. It combines theory, research, and practice. (Author/JEL)

The problems of two way analysis of variance designs with unequal and disproportionate cell sizes are discussed. A variety of solutions are discussed and a new solution is presented. (JKS)

Promoting innovations accounts for approximately 10 percent of the federal aid to public schools which currently exceeds $3.5 billion annually.

Focuses on factors or behaviors considered most influential in affecting communication climate within a large telecommunications corporation. (MH)

Two alternatives to the classical ANOVA procedure are presented to illustrate ways in which researchers may avoid the necessity of having to test the validity of assumptions and to perform data transformations. An illustrative application of these procedures is made to base running in baseball. (MJB)

The review of some recent studies on use of microcomputers in early childhood special education highlights methodological issues including the qualitative quantitative distinction and the interdependence of research design and interpretation. Imbedding qualitative methods into quasi- or true-experimental designs can provide more information than…

The experimental design and accompanying results of single-subject studies of two mentally retarded three-year-old boys suggested that multiple treatment interference can depend on the length of the changeover interval between treatments, and can also take the form of a lack of differential responding to various treatments.
