Current psychiatric nosology depicts posttraumatic stress disorder (PTSD) as a discrete diagnostic category. However, only one study has examined the latent structure of PTSD, and this study suggested that PTSD may be more accurately conceptualized as an extreme reaction to traumatic life events rather than a discrete clinical syndrome. To build…

There is need for objective and reliable single-case research (SCR) results in the movement toward evidence-based interventions (EBI), for inclusion in meta-analyses, and for funding accountability in clinical contexts. Yet SCR deals with data that often do not conform to parametric data assumptions and that yield results of low reliability. A…

Part one of this article described the first two stages that schools move through as they learn to link data to higher student achievement. In stage one, schools make initial efforts to contextualize the many data sources available, but their data analysis is mostly for its own sake. In stage two--using data to improve educational efficiency--the…

In this article, the authors describe how to construct a mock crime scene, acquire a pig carcass, sample its arthropod fauna, integrate photographic, climatic and arthropod successional data, and estimate the postmortem interval (PMI) from insect successional timetables. The experimental layout described in this article represents the untreated…

This paper discusses research premised on the view that new employees' necessary learning actions may be said to constitute a socio-cultural constructivist epistemology of necessity. It examines the work and learning activities of three new employees during their first months at a wholesale fruit and vegetable company. It proposes that what new…

The identity work engaged in by Indigenous teachers in school settings is highlighted in a study of Australian Indigenous teachers. The construction of identity in home and community relationships intersects with and can counteract the take up of a preferred identity in the workplace. In this paper we analyse data from interviews with Indigenous…

The purpose of the study was to investigate practices that high school teachers in Taiwan use to facilitate school-to-work transition, and to determine the importance ratings of each of these transition practices. A questionnaire with 28 transition practices was developed and sent out to the 125 participants in 24 special high schools in Taiwan;…

Large-scale scale testing agencies, which are generally located within provincial ministries of education and the Council of Ministers of Education, Canada, have called for secondary data analysis of test and survey data that link contextual and educational factors to student performance. First, the potential of secondary analyses is outlined,…

A key component to the new wave of performance-based pay initiatives is the use of student achievement data to evaluate teacher performance. As greater amounts of student achievement data are being collected, researchers have been developing and applying innovative statistical and econometric models to longitudinal data to develop measures of an…

This study examines non-completion of Year 12 at school for a nationally representative sample of young people who were 15 years old and still attending school in 2003. The study explores relationships between non-completion and selected socio-demographic and school-related factors, and changes in rates of school non-completion from the early…

The goal of teaching technology used in every field of daily life as well as in every stage of education, is to have individuals acquire the necessary skills in technology use. In this era, these skills are among the essentials for individuals to discover the world with the help of technology. This study was carried out on students who completed…

An assessment framework is like a blueprint, laying out the basic design of the assessment by describing the mathematics content that should be tested and the types of assessment questions that should be included. It also describes how the various design factors should be balanced across the assessment. This is an assessment framework, not a…

The purpose of this article is to introduce the Early Childhood Longitudinal Study-Kindergarten (ECLS-K) database to school social work practitioners and researchers. This database not only serves as a viable source for evidence-based practice pertaining to the influences of families and schools on the academic achievement of children beginning at…

This analysis of data from the Partnership for Literacy Study investigates the relationship among achievement, effort, and grades. Certainly, grades reward achievement, the mastery of material by students. Research has also suggested that grades are used to reward students for exerting effort to learn material, even if students fall short of…

The current study tests a theoretical model illustrating a potential pathway to reactive aggression through exposure to a traumatic event (Hurricane Katrina) in 166 adolescents (61% female, 63% Caucasian) recruited from high schools on the Gulf Coast of Mississippi. Results support an association between exposure to Hurricane Katrina and reactive…
