Over the past decade, transdisciplinary research has been faced with increasing demands by research policy and funding bodies to make its contribution to dealing with complex societal problems more transparent. In the literature, there is a range of methodological attempts to trace and describe the effects of transdisciplinary research, but these…

Text classification has allowed researchers to analyze natural language data at a previously impossible scale. However, a text classifier is only as valid as the the annotations on which it was trained. Further, the cost of training a classifier depends on annotators' ability to quickly and accurately apply the coding scheme to each text. Thus,…

This study revisits the task of case selection in case study research, proposing a new typology of strategies that is explicit, disaggregated, and relatively comprehensive. A secondary goal is to explore the prospects for case selection by "algorithm," aka "ex ante," "automatic," "quantitative,"…

Baeysian Network Meta-Analysis represents a rather unique challenge in assessing the quality of included studies. Prior efforts to synthesize computer based scaffolding are in need of a closer examination of research quality. This study examines two quality metrics for meta-analysis, study design, and risk of bias (Higgins et al., 2011). Lower…

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the "surface" method, the "frontier" method, the "binding-score" method, and…

The purpose of this article is to clarify the discrepancy in the use of "queer" as a sexual identity classification in education survey research. This study extends the work completed by Dugan and Yurman (2011), who empirically demonstrated problems with treating LGB students as a homogenous population through collapsing all respondents…

The study of postsecondary students with disabilities has a relatively short history that largely began with descriptions of programs designed for returning World War II veterans with disabilities and expanded in the 1970s with the advent of Section 504 of the Rehabilitation Act of 1973. Currently, the literature about postsecondary-level students…

This project was a qualitative longitudinal research study into cultural and structural change in an English secondary school. The schools' consistent underperformance led to its conversion to "academy" status as part of a development under the Labour administration of 1997-2010. The Labour policy for academization was designed, first,…

Students with invisible disabilities such as mental illness or acquired brain injury (ABI) experience multiple barriers that reduce their likelihood of postsecondary course completion. The present study conducted a systematic search of research reporting interventions for students experiencing mental illness or ABI to participate in postsecondary…

Though retrieving information typically results in improved memory on a subsequent test (the testing effect), Peterson and Mulligan (2013) outlined the conditions under which retrieval practice results in poorer recall relative to restudy, a phenomenon dubbed the "negative testing effect." The item-specific-relational account proposes…

In education research, small samples are common because of financial limitations, logistical challenges, or exploratory studies. With small samples, statistical principles on which researchers rely do not hold, leading to trust issues with model estimates and possible replication issues when scaling up. Researchers are generally aware of such…

Effectively educating the large English learner population requires policymakers to ensure developmentally appropriate settings and services throughout the time students are learning English, as well as during their transition to fluent English proficient status--a process termed "reclassification." Using longitudinal student-level data…

Assessments in response formats with ordered categories are ubiquitous in the social and health sciences. Although the assumption that the ordering of the categories is working as intended is central to any interpretation that arises from such assessments, testing that this assumption is valid is not standard in psychometrics. This is surprising…

Many current national and institutional education policies address the issue of raising participation amongst young people and enhancing employability after leaving school or university. What sort of information are these policies built on? This paper compares national information systems from the last three decades across Europe that gather…

This article describes a predictive model that assesses whether a student will have greater perceived learning in group assignments or in individual work. The model produces correct classifications 87.5% of the time. The research is notable in that it is the first in the education literature to adopt a predictive modeling methodology using data…
