High teacher turnover imposes numerous burdens on the schools and districts from which teachers depart. Some of these burdens are explicit and take the form of recruiting, hiring and training costs. Others are more hidden and take the form of changes to the composition and quality of the teaching staff. This study focuses on the latter. We ask how…

Students with disabilities have been included in state accountability systems for more than a decade; however, only in the past few years have alternate assessments of alternate achievement standards (AA-AAS) become stable enough to allow examination of these students' achievement growth. Using data from Oregon's AA-AAS in Reading during the…

Prior concerns have been raised about the ability of schools to access evidence-based practices, however, these practices are instrumental for addressing behavior concerns. This is particularly true at the secondary level, where students are more likely to be disproportionately identified for school removal. This review investigates studies of…

This study, which aims to determine the design principles of interaction adaptation in adaptive online learning environments, was based on a mixed and comparative type of relational screening model. Modified online Delphi method was employed in order to develop the principles and determine the relative importance. Ninety experts participated in…

The majority of existing research on mobility indicates that students do worse in the year of a school move. This research, however, has been unsuccessful in isolating the causal effects of mobility and often fails to distinguish the heterogeneous impacts of moves, conflating structural moves (mandated by a school's terminal grade) and…

In recent years, states have sought to increase accountability for public school teachers by implementing a package of reforms centered on high-stakes evaluation systems. We examine the effect of these reforms on the supply and quality of new teachers. Leveraging variation across states and time, we find that accountability reforms reduced the…

In the current study, we evaluated various robust statistical methods for comparing two independent groups. Two scenarios for simulation were generated: one of equality and another of population mean differences. In each of the scenarios, 33 experimental conditions were used as a function of sample size, standard deviation and asymmetry. For each…

Global university rankings are often thought of as games, defined by roles and rules that universities must play in order to confirm their legitimacy and gain visibility as actors in the global academic market. While some countries are well represented at the top of rankings charts, others are just joining the race and testing out different…

We study a teacher incentive policy in Washington State that awards a financial bonus to National Board Certified Teachers who teach in high-poverty schools. We study the effects of the policy on student achievement and teacher staffing using a regression discontinuity design that exploits the fact that eligibility for the bonus is based on the…

Teacher burnout is conceived as a general concern in special education because of the emotionally demanding work context. This study explored the potential role of perceived support for reduction of burnout in a sample of 276 special education teachers working in lower (n=130) and higher (n=146) secondary schools. Participants completed the…

Mentoring programs are increasingly widespread in academia. Still, comparatively little is known about their effects. With the help of a self-collected dataset of 368 researchers in two different fields and accounting for self-selection via matching techniques, we find mentees in formal mentoring programs to be more productive than comparable…

Research into work-integrated learning continues to show through a variety of small-scale and anecdotal studies, various positive impacts on student learning, work-readiness, personal and cognitive development and other outcomes. Seldom are these research findings strongly generalizable because of such factors as small sample sizes,…

The aim of this paper is to provide an introduction of new imputation algorithms for estimating missing values from official statistics in larger data sets of data pre-processing, or outliers. The goal is to propose a new algorithm called IRMI (iterative robust model-based imputation). This algorithm is able to deal with all challenges like…

When performing a meta-analysis unexplained variation above that predicted by within study variation is usually modeled by a random effect. However, in some cases, this is not sufficient to explain all the variation because of outlier or unusual studies. A previously described method is to define an outlier as a study requiring a higher random…

The Wechsler Preschool and Primary Scale of Intelligence-Fourth Edition (WPPSI-IV; Wechsler, 2012) represents a substantial departure from its predecessor, including omission of 4 subtests, addition of 5 new subtests, and modification of the contents of the 5 retained subtests. Wechsler (2012) explicitly assumed a higher-order structure with…
