This special issue marks the 50th anniversary of the landmark Pygmalion experiment (Rosenthal & Jacobson, 1968). It offers contributions from across the globe, attesting to universal features of teacher expectancy effects. Reviews of this history underscore controversy, advances, and few intervention studies. Empirical studies emphasise…

Based on a review of GPA and SAT/ACT requirements at 221 institutions in 25 states, a new report from the National Council on Teacher Quality (NCTQ) recommends that states, institutions of higher education, and the Council for the Accreditation of Educator Preparation (CAEP) maintain or establish a higher bar for entry into teacher preparation…

While scholars develop research with clear implications for policy and practice, this work has been largely ineffective in influencing thought beyond the academy. In this article, we explore challenges researchers face in designing public scholarship to influence policy. To illustrate, we profile one such effort, the "Opportunity to Learn…

In the current article, we consider the influential position of the Programme for International Student Assessment (PISA) and discuss several methodological areas that demonstrate the need for caution when using and interpreting PISA results. We motivate our argument by briefly describing the program's increased influence in educational policy…

Valid, scientific research is critical for ascertaining the effects of instructional techniques on learners with disabilities and for guiding effective special education practice and policy. Researchers in fields such as psychology and medicine have identified serious and widespread shortcomings in their research literatures related to replication…

The essay examines the variety of research methods and measures used in the first-year experience and students-in-transition field over the past 25 years. Interrogating the extant research, Kinzie explores whether the methods and analytic processes most commonly employed are adequate to advance our understanding of complex issues in the field. The…

Current economic conditions and the increasing competition for government funding are leading to an increased focus on the impact of research. Measuring the impact of research is difficult because not all impacts are direct and some can be negative or result from the identification of problems that require a non-research response. The time between…

This report critically examines studies of how scientific research drives innovation which is then translated into socio-economic benefits. It focuses on research evaluation insights that are relevant not only to the academic community, but also to policymakers and evaluation practitioners--and particularly to biomedical and health research…

Numerous misuses of statistics are described and illustrated, and ways of recognizing and avoiding such misuse are discussed. The following five categories of statistical misuse are identified: a lack of knowledge of the subject matter, the quality of the basic data, the preparation of the study and the report, the statistical methodology, and a…

Focuses on applications of a widely cited empirical study in the communication field--A. Mehrabian and S. Ferris' 1967 study that inferred that communication is 7% verbal, 38% vocal, and 55% facial. Notes that these applications overlook important limitations which do not warrant formulation of a precise numerical formula. Discusses lessons…

The use of hypothesis testing is widespread in occupational education research. In this, the first of two parts dealing with hypothesis testing, the authors show that considering Type II error can strengthen research results. (Author)

Notes problems in measuring attitudes about reading, critically examines some existing measures, and discusses the relevancy of such measures for classroom use. (GT)

Five research studies dealing with spelling achievement in New Zealand schools have been conducted; these include dictated-word spelling tests, written language studies, and achievement data collections of 20,000 students. Several conclusions emerge from an examination of this research: spelling achievement studies should be based on samples of…

Analysis of Pegnato and Birch's data invalidates the observation that teacher nominations should not be relied upon in gifted identification, as analysis shows that effectiveness and efficiency are related to number of subjects singled out as a result of the chosen cutoff value. An alternative is presented: compare correlation coefficients of the…

Reviews Tennessee's Project Student/Teacher Achievement Ratio (STAR) and puts the results in the context of other nonexperimental evidence about class size. Nonexperimental evidence does not support any achievement gains attributable to class-size reduction, and empirical evidence from STAR has design and implementation flaws that cast doubt on…
