Discusses several issues that pertain to analysis of data from repeated measurements designs. Notes that necessity for assumption concerning uniformity of correlations can be avoided by calculating linear and/or nonlinear trend scores. Discusses advantages of separately calculated trend scores. Proposes conservative criterion for use of one-sided…

Notes that, although accurate estimates of substance abuse are essential for adequate treatment planning, the value of national surveys in estimating local incidence of abuse is questionable. Compares local data on substance abuse with national incidence figures, reviewing studies that explore the problem of underreporting. Implications for…

This article shows that D. L. Hintzman's criticism of the Tulving-Wiseman function is based on an unjustified assumption that is implicit in his simulation procedure, an assumption that is at variance with empirical facts. A more appropriate hypothesis makes the discrepancy between average maximum and algebraic maximum disappear. (SLD)

The Center for the Advancement of Engineering Education was founded in 2003 with five collaborating institutions. A multi-institutional, multi-year grant offers many opportunities for the demands of reality to interfere with design goals. In particular, at Colorado School of Mines (CSM) student demographics required adjustment of the original APS…

The author was invited to prepare a commentary in response to the Lev-Wiesel manuscript titled "Intergenerational Transmission of Sexual Abuse? Motherhood in the Shadow of Incest." Lev-Wiesel's stated intent in the study was to understand an important issue, namely how is intra-familial sexual abuse perpetuated across successive generations. This…

The sexual abuse of children has received a tremendous amount of attention in recent years. Accordingly, both the criminal justice and mental health systems deal with child molesters. Since much of the public concerns revolve around the potential dangerousness of any given child molester, practitioners are frequently responsible for making…

Coding interactional data for statistical analysis presents theoretical, methodological and practical challenges. Coding schemes rely on categories that are decided by their relevance to the analytical problem under investigation. We suggest that (1) endogenous and publicly displayed concerns of participants provide for the observable organisation…

This paper shows that so-called "threshold concepts" have been defined in a way that makes it impossible, even in principle, to empirically isolate them. It continues by proposing an alternative theoretical framework, and argues: (1) that concepts are not reducible to abilities; (2) that acquisition of a given concept can be necessary, but not…

In this paper, I map important "messy" elements that I learned from my five-month small-scale research project, one that was designed around pivotal works on online social research. I used computers and the Internet with Minan, a young man living in Guinea, West Africa, in order to examine his perceptions surrounding the value of these…

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…

The What Works Clearinghouse (WWC) provides online reports to the public about the scientific evidence for educational interventions. The quality of these reports is important because they effectively tell the non-scientific community which programmes do and do not work. The aim of this brief review is to assess WWC's report on a clinically…

One goal of basic research in education is to identify the variables of effective instruction. As this pursuit has been conceived, however, its theoretical problems make it unlikely that the effort will provide a clear picture of instructional variables, their interactions, or the kind of teacher training that is implied by instructional variables.

Classic parametric statistical significance tests, such as analysis of variance and least squares regression, are widely used by researchers in many disciplines, including psychology. For classic parametric tests to produce accurate results, the assumptions underlying them (e.g., normality and homoscedasticity) must be satisfied. These assumptions…

Few research studies have investigated the effectiveness of instructional strategies for students in juvenile corrections. The dearth of research on effective instruction for this population may be due in part to difficulties encountered in carrying out methodologically rigorous studies in these settings. This article reports barriers and…

Explored through a focus on the behaviour and related experiences of a 9 year old Muslim Somalian boy called Zak, Woods offered a fascinating in-depth case study account of the rewards and sanctions systems in place at a culturally and religiously diverse London primary school. Over a period of 18 months, Woods employed a range of methodological…
