This study examines sample characteristics of articles published in "Journal of Applied Psychology" ("JAP") from 1995 to 2008. At the individual level, the overall median sample size over the period examined was approximately 173, which is generally adequate for detecting the average magnitude of effects of primary interest to…

Publication patterns of articles in "Adultspan" from 1999 to 2009 were reviewed. Author characteristics and article content were analyzed to determine trends over time. Research articles were analyzed specifically for type of research design, classification, sampling method, types of participants, sample size, types of statistics used, and…

This paper presents a framework that captures the complexity of reasoning about variation in ways that are indicative of robust understanding and describes reasoning as a blend of design, data-centric, and modeling perspectives. Robust understanding is indicated by integrated reasoning about variation within each perspective and across…

A marginal maximum a posteriori (MMAP) procedure was implemented to estimate item parameters in the generalized graded unfolding model (GGUM). Estimates from the MMAP method were compared with those derived from marginal maximum likelihood (MML) and Markov chain Monte Carlo (MCMC) procedures in a recovery simulation that varied sample size,…

In an effort to find evidence of the effectiveness of an accommodation which students with reading based disabilities are allowed to use on state assessments, a group of 11 fifth graders identified as having a reading based disability and having at least one reading goal in their Individual Education Programs (IEP) were given a series of short…

Just as PK-12 teachers are taught how to teach, college and university professors should also receive instruction in how to teach. They should acquire pedagogical skills and understand methods for planning and content delivery prior to entering the classroom. The knowledge base of the discipline and a focus on research are emphasized in the…

Validity is a central principle of assessment relating to the appropriateness of the uses and interpretations of test results. Usually, one of the inferences that we wish to make is that the score reflects the extent of a student's learning in a given domain. Thus, it is important to establish that the assessment tasks elicit performances that…

Outsourcing of jobs to contract workers who work alongside a client's employees has changed the human resource landscape of many organizations. In this study we examine how a contract worker's perceived employment status similarity to the client's own standard employees influences his/her affective commitment to both the client and the employer…

Parameter recovery was assessed within mixture confirmatory factor analysis across multiple estimator conditions under different simulated levels of mixture class separation. Mixture class separation was defined in the measurement model (through factor loadings) and the structural model (through factor variances). Maximum likelihood (ML) via the…

In 2010, the European Higher Education Area (EHEA) was launched in many countries of the European Union. A major part of this initiative concerns the development of common policies for the quality assessment of higher education institutions, a process that is widely regarded as of utmost importance, and in which students have significant…

Previous studies of different methods of testing mediation models have consistently found two anomalous results. The first result is elevated Type I error rates for the bias-corrected and accelerated bias-corrected bootstrap tests not found in nonresampling tests or in resampling tests that did not include a bias correction. This is of special…

Investigations of whether students taking undergraduate work placements show greater academic improvement than those who do not have shown inconsistent results. In most studies, sample sizes have been relatively small and few studies have taken into account pre-existing student differences. Here data from over 6000 students at one university over…

Purpose: The purpose of this study was to identify the organizational factors that influence electronic health information exchange (HIE) by medical group practices in rural areas. Methods: A purposive sample of 8 small medical group practices in 3 experimental HIE regions were interviewed to determine the extent of clinical information exchange…

Student learning skills differ depending on gender. The importance of studying this situation in the classroom is that recommendations can be made taking gender into consideration. In e-learning, the roles of students and teachers change. In line with recent research, the question this paper raises is whether or not gender differences also exist…

This document provides guidance about how to describe studies and report their findings in a way that is clear, complete, and transparent. This document does not include information about how studies are judged against What Works Clearinghouse evidence standards. For information about What Works Clearinghouse evidence standards, please refer to…
