Describes a method of dealing with partially-responded-to questionnaires in survey research which utilizes nonparametric Bayesian discriminant analysis to predict missing responses based on "profiles" of the partial and the "complete" respondents. Some background of nonresponse bias in survey research is discussed, and two other methods of dealing…

A description of the use of power analysis in controlling the probability of a Type II error, and hence in the construction of a suitable research design, is given. (MN)

A revision of the August 1976 set of criteria for evaluating research proposals and reports, issued by the research advisory Committee of the National Council of Teachers of Mathematics, is given. (MN)

Whereas group research designs inform us about aggregate experience, single case models seek to answer research questions by a more complete analysis of an individual's life. This article focuses on three single case methodologies: psychohistory, case study, and intensive experimental design. The influence of the holistic perspective is discussed.…

The authors review nineteen evaluations and reports dealing with alternative schools, examining the structure of the research, findings, and recommendations. In an examination of the research methodology, weaknesses are described and suggestions for improving the quality of future research are made. (MJB)

Presents a theoretical discussion of the role of cohort effects in the study of human development. The paper examines three problems associated with cohort analysis. These involve the interrelated problems of defining boundaries, defining distinctive experiences, and analyzing typical response patterns. (BD)

This critique points out weaknesses regarding the test measures used by Munsinger and Douglass and questions the validity of these measures for the ages of the children used in their study. (JMB)

This paper suggests that, at present, a science of natural developmental processes does not exist because few studies are concerned with development as it transpires in naturalistic environments and because truly developmental data are not collected or analyzed. (Author/JMB)

Defines and discusses the concept of linearity in the design and conduct of research and suggests general considerations for dealing with the problem of linearity in naturalistic inquiry in speech communication studies. (MH)

Describes studies on the outcomes of psychiatric rehabilitation in terms of setting predominant focus of the intervention outcome measures and interventions used. Shows the effectiveness of rehabilitation interventions for decreased recidivism, increased time spent in the community, increased rates of employment and productivity, increased skill…

Described is a teaching method for chemistry that gives college students practice in experimental design. Students are given a problem and required to design a procedure to solve the problem. Problems increase in complexity as the students progress through the courses. (RH)

A new theory linking information extraction patterns to the visual perception of direction and extent is presented. Seven demonstration experiments employ predictions from efferent considerations to create a new set of illusions of direction and extent and to demonstrate new predictable variations in the magnitude of some classical illusion…

Presents a two-pronged attempt to synthesize the research on stress coping: (1) a review of models and taxonomies of behaviors and resources related to stress coping and (2) a meta-analysis of recent experimental and quasi-experimental studies of stress coping. A taxonomy and a model of stress coping are offered, and implications for treatment are…

Information that describes a program's implementation and client audience can help the evaluator tailor the study to the constraints of particular settings and increase the likelihood that the evaluation can be implemented as planned. (Author/BS)
