The effect of rating augmentation on inter-rater reliability: An empirical study of a holistic rubric

A two-stage process by which a holistic rubric is applied to the assessment of open-ended items, such as writing samples, is defined. The first stage involves scoring a performance by the assignment of an integer rating that is congruent with the proficiency level that is exhibited in the performance. The second stage is the subsequent assignment by the rater of an augmentation that indicates whether or not the writing competency reflected in the paper is a bit higher or lower than the competency level reflected in the benchmark paper for the given proficiency level. If the rater feels that the paper represents benchmark proficiency for the given level, no augmentation is assigned to the rating. The results of this study indicate that the use of rating augmentation can improve the inter-rater reliability of holistic assessments, as indicated by generalizability phi coefficients, correlation coefficients, and percent agreement indices. Implications and suggestions for follow-up research are discussed.     

A study of cross-national collaborative research: reflecting on experience in Pakistan

This paper seeks to offer insights into the complexities involved in cross-national collaborative research. It identifies and provides an account of the various issues running through the research process, whilst at the same time derives principles upon which such work should be based. Key narratives were identified by highlighting a number of critical incidents. These narratives were related to issues of ownership, trust, and power, whilst in the course of theorising the research process itself, the metaphors of voice and crossing borders were found to be profoundly empowering and transformative. The complexities of working cross-nationally in the research group, understanding roles, clarifying professional frames and ethical values, at the same time as creating and maintaining a context for effective partnership and participation, made managing and sustaining the research process challenging.     

Cross-sectional comparison of body composition and resting metabolic rate in Premier League academy soccer players: Implications for growth and maturation

ABSTRACT

For the first time we aimed to: (1) assess fat-free mass (FFM) and RMR in youth soccer players, (2) compare measured RMR to estimated RMR using previously published prediction equations, and (3) develop a novel population-specific prediction equation. In a cross-sectional design, 99 males from a Premier League academy underwent assessments of body composition (DXA) and RMR (indirect-calorimetry). Measured RMR was compared to estimated values from five prediction equations. A novel RMR prediction equation was developed using stepwise multiple regression. FFM increased (P<0.05) between U12 (31.6±4.2 kg) and U16 (56.3±5.3 kg) after which no further increases occurred (P>0.05). RMR in the U12s (1655±195 kcal.day^?1), U13s (1720±205 kcal.day^?1) and U14s (1846±218kcal.day^?1) was significantly lower than the U15s (1957±128 kcal.day^?1), U16s (2042±155 kcal.day^?1), U18s (1875±180 kcal.day^?1) and U23s (1941±197 kcal.day^?1) squads (P>0.05). FFM was the single best predictor of RMR (r²=0.43; P<0.01) and was subsequently included in the novel prediction equation: RMR (kcal.day^?1) = 1315 + (11.1 x FFM in kg). Both FFM and RMR increase from 12-16 years old, thus highlighting the requirement to adjust daily energy intake to support growth and maturation. The novel prediction RMR equation developed may help to inform daily energy requirements.     

The psychology of containment: (mis) representing emotional and behavioural difficulties in Australian schools

The number of students in special schools has increased at a rapid rate in some Australian states, due in part to increased enrolment under the categories of emotional disturbance (ED) and behaviour disorder (BD). Nonetheless, diagnostic distinctions between ED and BD are unclear. Moreover, despite international findings that students with particular backgrounds are over-represented in special schools, little is known about the backgrounds of students entering such settings in Australia. This study examined the government school enrolment data from New South Wales, the most populous of the Australian states. Linear and quadratic trends were used to describe the numbers and ages of students enrolled in special schools in the ED and BD categories. Changes between 1997 and 2007 were observed. Results showed an over-representation of boys that increased across the decade and a different pattern across age for boys and girls. Consistent with international findings, these results indicate that trends in special school placements are unrelated to disability prevalence in the population. Rather, it is suggested that schools act to preserve time and resources for others by removing their more challenging students: most typically, boys.     

‘Seeing’ into the past and ‘looking’ forward to the future: visual methods and gender and education research

A small number of attempts have been made to take stock of the field of gender and education, though very few have taken methodology as their explicit focus. We seek to stimulate such discussion in this article by taking stock of the use of visual methods in gender and education research (particularly participatory and image-based methods). We undertake this exercise by looking at the claims researchers have made about the ways in which visual methods have advanced gender and education research, and by examining how these methods have been employed in research. We argue that the visual has become somewhat invisible in accounts of gender and education research. We conclude by considering different ways in which we might develop image-based research in the future.     

Rethinking the ‘Western Tradition’

Abstract

In recent years, the ‘Western tradition’ has increasingly come under attack in anti-colonialist and postmodernist discourses. It is not difficult to sympathise with the concerns that underlie advocacy of historically marginalised traditions, and the West undoubtedly has a lot to answer for. Nonetheless, while arguing a qualified yes to the central question posed for this special issue, we question the assumption that the West can be neatly distinguished from alternative traditions of thought. We argue that there is fundamental implicit and explicit agreement across traditions about the most difficult of issues and on standards about how to reason about them and that the ‘West’ has demonstrably learned from within and without itself. But, we question the very viability under conditions of heightened globalisation and neo-colonialism of distinguishing between thought of the ‘West’ and thought outside the West. It is time to move beyond the reified assumptions that underlie the idea of ‘Western thought’, cast as an agent with a collective purpose.     

How Birth Doulas Help Clients Adapt to Changes in Circumstances,Clinical Care,and Client Preferences During Labor

This study examined how doulas adapt to challenges in client’s labors. There were 104 Canadian and 92 American doulas who responded to a survey distributed at a doula conference. We report results from open-ended questions in which doulas describe how they manage changes deviating from the mother’s birth plan and how they navigate differences of opinion between themselves and providers. Four themes emerged: giving nonjudgmental support, assisting informed decision making, acting as a facilitator, and issues with advocacy. Although 30% of doulas said that advocacy and information giving could result in conflict with providers, doulas reported working within their scope of practice and striving to be part of the team. Issues in doula responsibility and patient advocacy remain, and ongoing role clarification is needed.     

What is literacy for students with severe learning difficulties? Exploring conventional and inclusive literacy

This paper arises from research into inclusive literacy for pupils with severe learning difficulties who do not learn to read and write conventionally. The ultimate aim of the study was to seek out examples of good practice in teaching and learning literacy that includes students with severe learning difficulties and disseminate them as widely as possible. Thirty-five schools were visited and observations made in 122 lessons. Sixty-one teachers were interviewed and their paperwork examined. Ten focus groups and five 'expert witnesses' were consulted, alongside desk-based research designed to locate 'good practice'. Teachers used a mixture of conventional (e.g., texts) and non-conventional (e.g., pictures, film and oral) media, although more observations were made of conventional literacy teaching (e.g., phonic work) than of non-conventional (e.g., filmmaking). Results from the research suggest that few students with severe learning difficulties are likely to learn to read and write conventionally (i.e., read for pleasure, work and study) and teachers may be relying too much on teaching traditional literacy to them. It may be useful to explore teaching and learning around alternative media such as still and moving images, live theatre and storytelling, digital technology and the arts. Although some teachers are making good use of these media, the potential of these media for providing inclusive literacy experiences could be further developed.
