Two Monte Carlo simulations were performed to compare methods for estimating and testing hypotheses of quadratic effects in latent variable regression models. The methods considered in the current study were (a) a 2-stage moderated regression approach using latent variable scores, (b) an unconstrained product indicator approach, (c) a latent…

Parents and caregivers faced with the challenges of transferring children with disability are at risk of musculoskeletal injuries and/or emotional stress. The Caregiver Self-Efficacy Scale for Transfers (CSEST) is a 14-item questionnaire that measures self-efficacy for transferring under common conditions. The CSEST yields reliable data and valid…

Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In "planned missing data designs", missing data are used…

This study examined the psychometric proprieties of the Arabic version of the Curriculum-Based Measurement Oral Reading Fluency (CBM ORF) for Jordanian students. A sample of 200 students (six to eight years old) was recruited from four public primary schools in Jordan. Results indicated that the CBM ORF had adequate reliability and validity…

This study is part of the core research agenda of the five-year, Goal 3 grant funded by the Institute of Education Sciences, U. S. Department of Education "Improving the Teaching and Learning of English Language Learners: The Instructional Conversation Model." In video review of teaching, bias in evaluation or rating is evident in many…

Simulation games are becoming increasingly popular in education, but more insight in their critical design features is needed. This study investigated the effects of fidelity of open patient cases in adjunct to an instructional e-module on students' cognitive skills and motivation. We set up a three-group randomized post-test-only design: a…

School districts and states across the Regional Educational Laboratory Mid-Atlantic Region and the country as a whole have been modifying their teacher evaluation systems to identify more effective and less effective teachers and provide better feedback to improve instructional practice. The new systems typically include components related to…

There are relatively few examples of quantitative approaches to quality control in educational assessment and accountability contexts. Among the several techniques that are used in other fields, Shewart charts have been found in a few instances to be applicable in educational settings. This paper describes Shewart charts and gives examples of how…

The structure of the Hypomanic Personality Scale was explored in a sample of young adults (N = 884); resulting structures were validated on subsamples with measures of personality traits, internalizing symptoms, and externalizing behaviors. Hierarchical cluster analysis and estimates of general factor saturation suggested the presence of a weak…

This paper describes one reviewer's experience of reviewing for the journal "System" over an eight-year period, 2003-2011. The paper reports on the reviews produced by the single reviewer, which have been compiled into a specific purpose--an "occluded"--corpus (Swales, 1996) of 122 reviews, comprising 93,000 words. The paper first describes the…

South African organisations and particularly institutions of higher learning have been confronted with workforces that increasingly reflect the diversity of the South African population. This changing workforce composition implies that the multitude of individual and cultural differences and similarities become increasingly apparent among…

Purpose: Dog owners represent 40% of the population, a promising audience to increase population levels of physical activity. The purpose of this study was to develop and test the psychometric properties of a new instrument to assess social-cognitive theory constructs related to dog walking. Method: Dog owners ("N" = 431) completed the…

Mobile learning aims to utilise communication devices such as mobile devices and wireless connection in combination with e-learning systems, allowing learners to experience convenient, instant and suitable learning at unrestricted time and place. Participants were 125 Taiwanese senior high school students, whose continuance intention was examined…

Objectives: The training of physicians, nurse examiners, social workers and other health professional on the evidentiary findings of sexual abuse in children is challenging. Our objective was to develop peer reviewed training cases for medical examiners of child sexual abuse, using a secure web based telehealth application (TeleCAM). Methods:…

The study assessed computer literacy of secondary school teachers in Ekiti State. Three hundred teachers (Male = 150; Female = 150) selected from 30 public schools in 15 out of 16 local government areas participated. The instrument for collecting data was a 25-item Self-Assessment of Computer Literacy questionnaire and each item was rated on a…
