Notes inconsistencies in drug abuse prevention research findings related to such issues as study design and methodology. Presents consensus recommendations made by drug abuse prevention researchers and practitioners who met at National Institute on Drug Abuse in 1989. Includes specific recommendations directed to modifying prevention approaches;…

In this pilot study, 14 adolescents kept diaries for 6 consecutive weeks during their pregnancies. Diary entries were analyzed for affective tone, emotional lability, and contextuality. Findings question psychometric properties of data gathered using one time, self-report measures with pregnant adolescents because of their fluctuating mood states.…

Many evaluation researchers are now attempting to synthesize quantitative and qualitative approaches. Although such efforts appear to carry great promise, some subtleties and incompatibilities of these approaches are perhaps being overlooked. Implications for social inquiry are discussed.

Reviewed 65 reports, dated 1986 through 1990, focusing on college student alcohol consumption patterns. Review shows that shortcomings in research design, analysis, and presentation of results make it difficult to draw conclusions regarding the present nature and problem of college student drinking. (Author/NB)

A new report published by the Manhattan Institute for Education Policy, "The Effect of Special Education Vouchers on Public School Achievement: Evidence from Florida's McKay Scholarship Program," attempts to examine the complex issue of how competition introduced through school vouchers affects student outcomes in public schools. The…

A test of statistical significance is a procedure for determining how likely a result is assuming a null hypothesis to be true with randomization and a sample of size n (the given size in the study). Randomization, which refers to random sampling and random assignment, is important because it ensures the independence of observations, but it does…

Why conclusions of many outcome evaluations do not stand up to scrutiny is discussed, drawing on examples from evaluations of drug abuse prevention programs. Factors that undermine these studies are largely the result of social-structural problems that influence the design and implementation of the research. (SLD)

Findings of a study that determined the ways in which practicing administrative course developers utilize instructional design activities in their design projects are presented in this paper. A survey was administered to 30 participants in a training and development group within a large organization and mailed to 43 other practicing instructional…

At the request of a Senate subcommittee, this report describes the value of conducting impact evaluations, describes their current use in evaluating selected early childhood education and care programs, and discusses the value of other types of early childhood education and care studies currently promoted and sponsored by the Departments of Health…

Points out that early childhood development research is fraught with questions about researchers' ability to understand the mind of the child and the feasibility of true collaboration with children in the research process. Delineates common complications in the research process and summarizes responses to a survey of early childhood researchers…

The research literature provides important guidance to counselors working to keep abreast of the latest thinking regarding best practices and recently developed counseling tools. The purpose of this digest is to highlight a few errors that seem to recur within the literature, and to provide some helpful references that further explore these…

Argues research on the efficacy of special education is poor. Describes key flaws including (1) lack of proper control groups; (2) studies that utilize matching of similarly disabled students rather than random selection; (3) measurements of effectiveness; and (4) studies that have become outdated as the functional definitions of labels have…

Research in information and communication technology in education places an increasing emphasis on the use of qualitative analysis (QA). A considerable number of approaches to QA can be adopted, but it is not always clear that researchers recognize either the differences between these approaches or the principles that underlie them.…

Remedial or developmental courses are the most common policy instruments used to assist underprepared postsecondary students who are not ready for college-level coursework. However, despite its important role in higher education and its substantial costs, there is little rigorous evidence on the effectiveness of college remediation on the outcomes…

Considers the competing demands placed on evaluators in relation to the service (characteristics of the intervention), the sample (people participating), and methodology or research design. Explores compromises that may be required between scientific ideals and real-world limitations, and assesses implications for obtaining meaningful results in…
