Describes the use of simulated time sequences in the analysis of age-related and socio-historical changes in developmental research. (BD)

Discusses, in the context of library evaluation, the major sources of untrustworthy information and describes what can be done to control them. The emphasis is on assessing the impact of changed operations. (JD)

Commentary is presented on the evaluation of the Emergency School Aid Act and on an article detailing that evaluation (TM 503 672). The use of randomization and pilot studies is emphasized. (J KS)

The desirability of evaluating the total effect of the Emergency School Aid Act versus specific programs in the Act is the focus of this commentary on the evaluation of that act and an article detailing that evaluation (TM 503 672). (JKS)

Issues in analysis of covariance, multiple regression analysis, and the analysis of variance such as the assumption of independence and directional hypotheses are discussed. (JKS)

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)
