This note continues the discussion of earlier articles (TM 503 420, TM 503 706, and TM 503 707), comparing the completely randomized design with the randomized block design. (CTM)

Personal and telephone surveys are compared to measure differences between the modes for identical questions. Speed of questioning is greater in telephone interviews, and so open-ended items in telephone interviews yield shorter answers. Reduced responses are disproportionately exhibited by younger, affluent respondents, who often provide detailed…

Cronbach, in 1957, supported the unification of two disciplines of scientific psychology--the correlational and experimental approaches. The remaining papers in this journal issue--which served as the basis for a 1978 American Educational Research Association Symposium--address this issue. (Author/RD)

The controversy surrounding regression methods for unbalanced factorial designs is addressed. The statistical hypotheses being tested under the various methods, as well as salient issues in the use of these methods, are discussed. The use of statistical computer packages is also discussed. (Author/JKS)

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. (Author)

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. However, serious questions about the usefulness of federal efforts to promote innovation and the prospects for educational reform have been raised. Those questions were examined here by the Rand…

Some of the issues that affect the validity and reliability of research studies are discussed to aid readers in interpreting and evaluating research studies in shorthand. (MP)
