Previous research has shown that individual differences in working memory (WM) are highly predictive of a wide range of cognitive behaviours. Until recently, research has focused on monolingual, or undifferentiated, populations. The present research compares metacognitive awareness, as measured by self-ratings of reading, writing, speaking and…

The purpose of this study was to examine whether children with Asperger Syndrome and children with autism exhibit difference sensory profiles. The Sensory Profile (Dunn, 1999), completed on 86 individuals with Asperger Syndrome and 86 persons with autism matched for age, revealed differences in three of 23 areas evaluated: (a) Emotional/Social…

This paper examines evaluation in reading. Evaluation refers to the processes by which readers monitor their ongoing text comprehension to assess performance and task difficulties. Monitoring is assumed to explain a large proportion of individual differences in text comprehension, in that individuals need to be aware of their objectives and…

This qualitative multi-case study explored four young leaders' idiosyncratic leadership styles manifested within the context of their classrooms (toddler and preschool). In order to gain a deeper understanding of the complexity and variety of early childhood leadership and provide holistic descriptions of young leaders' emerging leadership…

Effective professional learning requires that staff developers thoughtfully plan to meet varying teacher needs and be responsive to differences--that they model the differentiation teachers will practice in the classroom. Staff developers must be mindful of participants' current learning needs and plan according to their readiness, interest, and…

This paper is the first to systematically document the relationship between individual teacher performance incentives and student achievement using United States data. We combine data from the National Education Longitudinal Survey on schools, students, and their families with our own survey conducted in 2000 regarding the use of teacher…

Background: The aim of the present study was twofold: 1) to determine whether phonological skills measured in deaf prereaders predict their later phonological and reading skills after one year of reading instruction as is the case for hearing children; 2) to examine whether the age of exposure to a fully specified phonological input such as Cued…

Little is known about the effects of social context or "place" factors (e.g., characteristics of local populations) on African Americans' perceptions and experiences of racism. Using data from 42,445 U.S. black women collected during the 1997 follow-up wave of the Black Women's Health Study, we investigated the association between neighborhood…

This study analyzed the production of voice onset time (VOT) for /p, t, k/ in Japanese and English by English-speaking children (n = 15) in a Japanese immersion program. The immersion children produced Japanese voiceless stops with significantly longer VOT values than the monolingual Japanese children and the immersion teachers, but they produced…

Implementation of information systems has lagged in many areas of clinical healthcare for a variety of reasons. Economics, data complexity and resistance are among the often quoted roadblocks. Research suggests that physicians play a major part in the adoption, use and diffusion of information technology (IT) in clinical settings. There are also…

This study investigated the differences between demographic, enrollment, academic, and self-directed learning characteristics of completers and noncompleters in online courses at one community college. The study also obtained students' self-reported reasons for not completing their coursework. No significant differences were found in the…

Individual differences in response to a given treatment have been a longstanding interest in education. While many evaluation studies focus on average treatment effects (i.e., the effects of treatments on the levels of outcomes of interest), this paper additionally considers estimating the effects of treatments on the dispersion in outcomes.…

Purpose: To examine substance use differences among African-American adolescents living in rural and more urban areas in Iowa and Georgia and factors thought to be related to those differences. Specifically, negative affect and perceived availability were examined as mediators of the relation between community size and alcohol, tobacco, and drug…

Background: The international literature has documented that self-determination is impacted by environmental factors, including living or work settings; and by intraindividual factors, including intelligence level, age, gender, social skills and adaptive behaviour. In addition, self-determination has been correlated with improved quality of life…

This book defines and reviews five central problems in the study of second language acquisition (SLA): (subconscious) transfer, staged development, cross-learner systematicity, incompleteness, and variability. The central thesis of the text is that linguistic knowledge is an autonomous component of SLA, distinct from the socially determined use of…
