Coefficient "H" is used as an index of scalability in nonparametric item response theory (NIRT). It indicates the degree to which a set of items rank orders examinees. Theoretical sampling distributions, however, have only been derived asymptotically and only under restrictive conditions. Bootstrap methods offer an alternative possibility to…

Recent studies have used pretreatment analyses, termed competing stimulus assessments, to identify items that most effectively displace the aberrant behavior of individuals with developmental disabilities. In most studies, there appeared to have been no systematic basis for selecting the sampling period (ranging from 30 s to 10 min) in which items…

The use of qualitative methods is increasing in the health education literature, and there is need for more information on these methods and their use. This investigation looks at qualitative sampling practices as reported in the 93 qualitative or mixed-method studies published in Health Education & Behavior from 1980 to 2000. It focuses…

This paper discusses grounded theory as one of the qualitative research designs. It describes how grounded theory generates from data. Three phases of grounded theory--open coding, axial coding, and selective coding--are discussed, along with some of the issues which are the source of debate among grounded theorists, especially between its…

This article reviews evidence and theories concerning the nature of stimulus representations in Pavlovian conditioning. It focuses on the elemental approach developed in stimulus sampling theory (R. C. Atkinson & W. K. Estes, 1963; R. R. Bush & F. Mosteller, 1951b) and extended by I. P. L. McLaren and N. J. Mackintosh (2000, 2002) and contrasts…

In an effort to generate innovative treatments, the National Institute of Mental Health has made translational research for alleviating mental illness a major funding priority. Although translational research is a powerful approach for moving basic science findings into novel treatments, it remains ambiguous and rarely implemented in psychology.…

The utility of value-added estimates of teachers' effects on student test scores depends on whether they can distinguish between high- and low-productivity teachers and predict future teacher performance. This article studies the year-to-year variability in value-added measures for elementary and middle school mathematics teachers from five large…

The traditional classroom teaching mode is based on the content of the subject, takes the teacher as the center and gives priority to classroom instruction. While PBL (Problem Based Learning) teaching method breaches the traditional mode, combining the basic science with clinical practice and covering the process from discussion to self-study to…

Forensic versus traditional accounting and auditing are compared and contrasted. Evidence gathering is detailed. Forensic science and fraud symptoms are explained. Criminalists, expert testimony and corporate governance are presented.

This study examined the relationship between data use and achievement at 13 urban Title I schools. Using multiple methods, including test scores, district surveys, school transformation plans, and four case study site visits, the researchers found wide variation in the use of data to inform instruction and planning. In some cases, schools were …

This book provides tools to enhance upper-level spelling and vocabulary instruction, and features more than 120 reproducible sorting activities and games. It offers suggestions for helping students build mastery of vowel patterns, syllable structure, syllable stress, consonant and vowel alternations, compound words, prefixes, suffixes, and word…

Objective: Family practitioners are significant providers of mental health care and routinely report difficulty acquiring timely support in this area. The Collaborative Mental Health Care Network assembled groups of family practitioners and provided them with mental health practitioner mentors. This article addresses communication in the Network,…

Objectives: To understand the current status of intellectually disabled children and the prevalence of intellectual disability (ID) in children aged 0-6 years and its risk factors, and to provide scientific evidence to formulate relevant policies for helping intellectually disabled children. Methods: Multiphase, stratified, unequal proportional…

The second section of a four-part technical report of Florida's statewide program for assessing reading-related skills in grades 2 and 4 provides statistical and scoring information. Item and student sampling, a test re-scoring study, reporting statewide assessment data (percentage of achievement, types of tables used), and standard error…

The U.S. Department of Education's National Center for Education Statistics has updated the household and prison public-use data files for the 2003 National Assessment of Adult Literacy and the 1992 National Adult Literacy Survey. The accompanying 2003 National Assessment of Adult Literacy Public-Use Data File User's Guide explains how the data…
