Auditory processing interventions and developmental dyslexia: a comparison of phonemic and rhythmic approaches

The purpose of this study was to compare the efficacy of two auditory processing interventions for developmental dyslexia, one based on rhythm and one based on phonetic training. Thirty-three children with dyslexia participated and were assigned to one of three groups (a) a novel rhythmic processing intervention designed to highlight auditory rhythmic information in non-speech and speech stimuli; (b) a commercially-available phoneme discrimination intervention; and (c) a no-intervention control. The intervention lasted for 6 weeks. Both interventions yielded equivalent and significant gains on measures of phonological awareness (at both rhyme and phoneme levels), with large effect sizes at the phoneme level. Both programs had medium effect sizes on literacy outcome measures, although gains were non-significant when compared to the controls. The data suggest that rhythmic training has an important role to play in developing the phonological skills that are critical for efficient literacy acquisition. It is suggested that combining both prosodic/rhythmic and phonemic cues in auditory training programs may offer advantages for children with developmental dyslexia. This may be especially true for those who appear resistant to conventional phonics training methods.     

Distribution of Methods of Teaching Arithmetic in Primary Schools in England and Wales∗

Background When an exam question is read, a mental representation of the task is formed in each student's mind. This processing can be affected by features such as visual resources (e.g. pictures, diagrams, photographs, tables), which can come to dominate the mental representation due to their salience.

Purpose The aim of this research was to investigate the effects of visual resources in exam questions and, in particular, to investigate how and when students use images and whether subtle changes to these salient physical features can affect whether a question is understood and answered in the way intended by the question-setters.

Sample The participants were 525 16-year-old students, with a range of ability, in four secondaryschools.

Design and methods Experimental test papers were constructed including six questions based on past examination questions and involving graphical elements. For five of the six questions, two versions were designed in order to investigate the effects of changes to visual resources on processing and responses. A sample of the students were interviewed afterwards.

Results Where two versions of a question were trialled in parallel, the differences in the visual resources significantly affected marks for one question and had smaller effects on marks and the nature of answers with some of the others. There were mixed views from students over whether a visual resource that is not strictly necessary should be used. Some considered it reassuring, whilst others deemed it unnecessary. Evidence in the literature suggests that caution may be needed since there is a risk that some students may pay too much attention to the image. Findings from one question (question 6) indicated that visuals can increase the likelihood of students making unhelpful interpretations of a question. Students were seen to have sensible expectations regarding when to use information from a visual resource and what is important in an illustration. In addition, more use tended to be made of a technical diagram (in question 12) in comparison to pictures or sketches, and it was found that if an image provides a clue to an answer, this may be used in preference to information in the text.

Evidence regarding the use that students made of a table (question 1) indicated that the data in the table cells were given more attention than some of the preceding text and text in a header. This might apply similarly to other resources like graphs and charts.

Conclusions It is important to ensure that the inclusion of a visual resource is carefully considered and appropriately designed. If a visual resource is not strictly needed in a question, the writer will need to balance the advantages and disadvantages. Authors should also consider whether and how students are likely to use or be affected by the particular visual resource chosen. The findings and suggested implications of this study are most applicable to high-stakes testing but may also be useful to those preparing school textbooks and to teachers in their preparation of classroom materials.     

“Your Tern Now My Tern Later”: A Tribute to the Outlaw Writer Russell Hoban

Russell Hoban died in December 2011. In this article, Victoria de Rijke celebrates this mysterious writer’s huge contribution to children’s literature over 52 years; a career which began and ended with two mythological books: The Mouse & His Child (1967) and Soonchild (2012). Published in CLE over the years, Hoban wrote about the importance of myth and the writer’s “outlaw self”. This piece explores his unique thinking about the craft of writing fantasy and actuality, and argues for books in “nameless categories” which children and adults can appreciate together.     

Development of an accelerometer-based multivariate model to predict free-living energy expenditure in a large military cohort

Abstract

This study developed a multivariate model to predict free-living energy expenditure (EE) in independent military cohorts. Two hundred and eighty-eight individuals (20.6 ± 3.9 years, 67.9 ± 12.0 kg, 1.71 ± 0.10 m) from 10 cohorts wore accelerometers during observation periods of 7 or 10 days. Accelerometer counts (PAC) were recorded at 1-minute epochs. Total energy expenditure (TEE) and physical activity energy expenditure (PAEE) were derived using the doubly labelled water technique. Data were reduced to n = 155 based on wear-time. Associations between PAC and EE were assessed using allometric modelling. Models were derived using multiple log-linear regression analysis and gender differences assessed using analysis of covariance. In all models PAC, height and body mass were related to TEE (P < 0.01). For models predicting TEE (r ² = 0.65, SE = 462 kcal · d^?1 (13.0%)), PAC explained 4% of the variance. For models predicting PAEE (r ² = 0.41, SE = 490 kcal · d^?1 (32.0%)), PAC accounted for 6% of the variance. Accelerometry increases the accuracy of EE estimation in military populations. However, the unique nature of military life means accurate prediction of individual free-living EE is highly dependent on anthropometric measurements.     

The ‘paradox of interdisciplinarity’ in Australian research governance

This paper identifies what can be called the ‘paradox of interdisciplinarity’ (Weingart 2000) in Australian higher education research governance and explores some of its constitutive dimensions. In the Australian context, the paradox of interdisciplinarity primarily concerns the proliferation of a programmatic discourse of interdisciplinarity in government reports and government policy and strategy documents, often tied to notions of innovation and applicability, parallel to the persistence or even reinforcement of modes of governance and associated mechanisms that almost exclusively rely on rigid discipline-based classification systems to evaluate and fund research. Two interrelated dimensions of this apparent paradox are discussed. First, the conceptions of knowledge that underpin the use of notions of disciplinarity as well as interdisciplinarity in Australian government reports and policy and strategy papers are analysed. Second, an analysis of the Australian research governance system and its underlying mechanisms is presented, as they pertain to interdisciplinary forms of research. On the basis of these analyses, it is concluded that there is a significant mismatch between the discourse of interdisciplinarity and associated conceptions of knowledge on the one hand, and current, relatively inflexible governmental research funding and evaluation practices on the other. It is finally proposed that the occurrence and perpetuation of such a mismatch in the Australian context can only be understood properly if placed in the context of a more general paradox of research governance, where a politically charged rhetoric of innovation conflicts with the actual trend toward an increasingly diminishing scope for the self-organisation of knowledge.     

Effects of a School for Pregnant Students on the Incidence of Low-Birthweight Deliveries

To evaluate effects of an alternative public school for pregnant teenagers in New Haven, CT, medical and school records were reviewed for a 1-year birth cohort of 230 adolescent mothers. Nearly three-quarters of all school-aged primiparas who were enrolled in the city's public schools when they became pregnant attended the alternative school. Because of summer vacation, however, students who conceived in January through April began attending later in pregnancy than did those who conceived in May through December; these mothers were significantly more likely to deliver a preterm, low-birthweight infant. No such seasonal effects were found for other teenagers in the city who were not enrolled in public school at conception. Positive birth outcomes for early program attenders are similar to those reported for a nurse-home-visitation program. The results suggest that school programs have considerable potential to be an effective service delivery model for providing prenatal intervention to adolescents.     

An Investigation of Rater Cognition in the Assessment of Projects

In the United Kingdom, the majority of national assessments involve human raters. The processes by which raters determine the scores to award are central to the assessment process and affect the extent to which valid inferences can be made from assessment outcomes. Thus, understanding rater cognition has become a growing area of research in the United Kingdom. This study investigated rater cognition in the context of the assessment of school‐based project work for high‐stakes purposes. Thirteen teachers across three subjects were asked to “think aloud” whilst scoring example projects. Teachers also completed an internal standardization exercise. Nine professional raters across the same three subjects standardized a set of project scores whilst thinking aloud. The behaviors and features attended to were coded. The data provided insights into aspects of rater cognition such as reading strategies, emotional and social influences, evaluations of features of student work (which aligned with scoring criteria), and how overall judgments are reached. The findings can be related to existing theories of judgment. Based on the evidence collected, the cognition of teacher raters did not appear to be substantially different from that of professional raters.
