This paper introduces an empirical strategy to estimate dynamic treatment effects in randomized trials that provide treatment in multiple stages and in which various noncompliance problems arise such as attrition and selective transitions between treatment and control groups. Our approach is applied to the highly influential four year randomized…

Rapidly declining response rates and the associated threat of nonresponse bias call into question the validity of data obtained through telephone surveys, a tool often used in evaluation. This article explores changes in nonresponse bias over time by examining three data points (1991, 1996, and 2002) from an annual household telephone survey…

This paper is a report of the replication of a seminal study on cognitive presence in computer mediated conferencing (CMC) by Garrison, Anderson, and Archer (2001). A comparison of cognitive presence coding by three different researchers is also demonstrated. The study re-ignites debates about what constitutes the segment of CMC data to be coded…

This article introduces the special issue, which focuses on the ways in which educational institutions in Europe and North America are responding to the growing number of children of immigrants entering schools and universities. It discusses the ways in which the needs of children of immigrants differ from those of native-born students, and the…

This article explores how the tensions that grow out of being a researcher in my community of queer Asian Americans lead to the formulation of a different kind of ethnographic approach. A hybrid notion of identity can require and inform a hybrid or poststructural ethnographic practice. This hybridized research method draws upon theoretical strands…

Two studies of the formation of pupils' subjectivities within the Danish school and educational system in the period 1945-2005 create the framework for a methodological discussion of how subjectivities in educational history can be studied. Both studies use qualitative interviews as a way of studying subject formations in educational history. This…

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.
