Reference data for the acoustic vowel space area (VSA) in children and adolescents do not currently appear to be available in a form suitable for normative comparisons. In the current study, individual speaker formant data for the four corner vowels of American English (/i, u, ae, [alpha]/) were used to compute individual speaker VSAs. The sample…

Subitizing is traditionally described as the rapid, preattentive and automatic enumeration of up to four items. Counting, by contrast, describes the enumeration of larger sets of items and requires slower serial shifts of attention. Although recent research has called into question the preattentive nature of subitizing, whether or not numerosities…

This article discusses the use of action research cycles on a course involving groupwork rehearsing and performance. The aim was to explore various pedagogic aspects of the activities and improve tutor practice. This account of four action research spirals, taking place over a 10-year period of rehearsing and performing, considers their management…

The present analysis revisits the economics of inattention and the resulting commoditization and creation of privileged goods. These act as a significant force that pushes human history toward a future that will be less livable and sustainable. The analysis traces the roots of these developments to the reorganization of human knowing and doing by…

The present study examined the directions of effects between adolescent psychopathic traits and parental behaviors. The data are from a community-based cohort-sequential study. Data were collected annually over 4 years. Participants were 875 adolescents, aged 13-15 at Time 1, and we analyzed their reports of negative and positive parental…

Consonant inventories are commonly drawn to assess the phonological acquisition of toddlers. However, the spontaneous speech data that are analysed often vary substantially in size and composition. Consequently, comparisons between children and across studies are fundamentally hampered. This study aims to examine the effect of sample size on the…

The Equality Act 2010 will be implemented in full in 2011, and schools in the UK will have to provide special aids or services for children with disabilities where this provision is considered reasonable. This paper reports on staff perspectives on the use and usefulness of a parental questionnaire on disability from a sample of 49 schools…

Criminologists have long been interested in understanding why people commit crime. Perhaps an even more interesting question is what accounts for the offending of individuals who occupy white-collar positions. Most explanations of white-collar offending have relied on extant criminological theories that have been developed to account for street or…

This study evaluated students' representational choices while they solved linear function problems. Eighty-six secondary-school students solved problems under one choice condition, where they chose a table, a formula, or both to solve each problem, and two no-choice conditions, where one of these representations was forced upon them. Two…

Simplified understandings of qualitative inquiry as mere method overlook the complexity and nuance of qualitative practice. As is the call of this special issue, the author intervenes in the simplification of qualitative inquiry through a discussion of methodology to illustrate how theory and inquiry are inextricably linked and ethically…

Conceptualizations of developmental trends are driven by the particular method used to analyze the period of change of interest. Various techniques exist to analyze developmental data, including individual growth curve analysis in observed and latent frameworks, cross-lagged regression to assess interrelations among variables, and multilevel…

While the potential benefits of participating in online learning communities are documented, so too are inequities in terms of how different populations access and use them. We present the online learning support roles (OLSR) framework, an approach using both automated analytics and qualitative interpretation to identify and explore online…

The early childhood education (ECE) sector in New Zealand has long been recognised for the diversity of service types and range of organisations involved in delivering ECE. However, less attention has been paid to diversity within individual ECE services. This article draws on a national survey carried out as part of a larger project, "The…

This study investigates Korean English teachers' responses to the current English Language Teaching (ELT) policies and reveals the attributes of their professional identity from their responses. Data collected from different narratives demonstrate that the teachers value the principles of communicative language teaching, but are not supportive of…

By combining an overall vision for the use of data, a commitment to protecting student privacy and data integrity, and supportive legislation, Georgia emerged as a leader in the effective use of student data. But it easily could have gone another way. None of the three elements could be taken for granted when Georgia set out to develop its state…
