The contributions of domain-general and numerical factors to third-grade arithmetic skills and mathematical learning disability
Explanations of the marked individual differences in elementary school mathematical achievement and mathematical learning disability (MLD or dyscalculia) have involved domain-general factors (working memory, reasoning, processing speed and oral language) and numerical factors that include single-digit processing efficiency and multi-digit skills such as number system knowledge and estimation. This study of third graders (N = 258) finds both domain-general and numerical factors contribute independently to explaining variation in three significant arithmetic skills: basic calculation fluency, written multi-digit computation, and arithmetic word problems. Estimation accuracy and number system knowledge show the strongest associations with every skill and their contributions are both independent of each other and other factors. Different domain-general factors independently account for variation in each skill. Numeral comparison, a single digit processing skill, uniquely accounts for variation in basic calculation. Subsamples of children with MLD (at or below 10th percentile, n = 29) are compared with low achievement (LA, 11th to 25th percentiles, n = 42) and typical achievement (above 25th percentile, n = 187). Examination of these and subsets with persistent difficulties supports a multiple deficits view of number difficulties: most children with number difficulties exhibit deficits in both domain-general and numerical factors. The only factor deficit common to all persistent MLD children is in multi-digit skills. These findings indicate that many factors matter but multi-digit skills matter most in third grade mathematical achievement

Unraveling the links between rapid automatized naming (RAN), phonological awareness, and reading
It is well established that phonological awareness (PA) and rapid automatized naming (RAN) tasks reliably predict children’s developing word reading abilities, across a wide range of languages. However, existing research has not yet demonstrated unequivocally whether RAN and PA are independently and causally linked to reading, nor fully explored the underlying cognitive mechanisms. Most existing research has assessed PA and RAN in children who may already have some reading skill, making direction of influence hard to ascertain. To address this, the current longitudinal research initially assessed RAN and PA in a very young sample of 91 English children (mean age: 3;11; SD = 3.7 months), demonstrated to be non-readers. Children were reassessed on RAN, PA, and word-level reading, 18 months (Time 2) and then a further year later (Time 3). To explore underlying mechanisms, separate measures of reading accuracy and fluency were taken, and reading tasks varied according to the extent to which they required alphabetic decoding and lexical, orthographic knowledge. Path analyses revealed that from Time 1 to Time 2 both RAN and PA predicted word reading, indicating temporal precedence, though there was some degree of reciprocity in these relationships. However, by Time 3, while RAN still predicted accuracy and fluency of reading, PA only predicted reading accuracy. Furthermore, findings suggested that while RAN was robustly related to both alphabetic decoding and lexical, orthographic aspects of reading, PA’s relationship was restricted to alphabetic decoding accuracy. Theoretical and practical implications are discussed
Language and decoding skills in Greek-English primary school bilingual children: effects of language dominance, contextual factors and cross-language relationships between the heritage and the majority language
Bilingual children are a heterogeneous population, as the amount of input and use of their languages may differ due to various factors, for example, the status of each language (majority, minority), which language is used in the school, and whether children are acquiring literacy in one or both languages. Their language ability depends to a large extent on the use of each language and
on whether they each language at the same rate. The aim of the study was to investigate how primary school bilingual children in the UK perform on several domains of language and reading skills and how these relate to language dominance. Moreover, it addressed how this performance is affected by a range of contextual factors and whether there are cross-language relationships
in the children’s language and reading abilities. Forty Greek-English bilingual children in Year 1 and Year 3 were tested on vocabulary, phonological awareness, morphological awareness, morpho-syntax, and decoding in Greek and English. The results showed that as a group, the children were Greek dominant before the age of 4 but English dominant now and confirm that language dominance could change even before children enter school and affects language and literacy skills equally. A strong
relationship between language use and performance was only in evidence in the minority language, which suggests that parental effort should be directed towards the minority language because schooling appears to level out differences in the majority language. There was no negative relationship between the use of the heritage language and children’s language and reading
performance in the majority language. In contrast, significant positive cross-language associations were revealed among vocabulary, phonological awareness, inflectional morphology and decoding skills. The practical implications of this study are that
parents and teachers should be informed for the positive effects of heritage language use in and outside the home for the maintenance of the heritage language and for the development of the children’s language and literacy skills

Making gains: the impact of outdoor residential experiences on students’ examination grades and self-efficacy
In this paper we explore the role of outdoor residential experiences on the sense of efficacy and examination attainment of a group of under achieving students from socially disadvantaged backgrounds. The paper reports on a three year project which focuses on two groups of year nine (age 14) to year eleven (age 16) students. The results reported here strongly suggest that the impact of these visits has been significant in terms of students’ sense of confidence and efficacy and had a statistically significant impact on formal examination results in school. We conclude by suggesting that outdoor residential experiences have real educational value for those that take part and, given the evidence provided, believe this poses an interesting question as to whether the classroom should remain the primary site of learning because of the ways it develops positive outcomes within school

Deficits in orthographic knowledge in children poor at rapid automatized naming (RAN) tasks?
The degree to which orthographic knowledge accounts for the link between Rapid Automatized Naming (RAN) and reading is contested, with mixed results reported. This longitudinal study compared two groups of 10-11 year old children, a low RAN group (N=69) and matched controls (N=74) on various measures of orthographic knowledge. The low RAN group showed a deficit in orthographic knowledge, both at the level of sub-word letter sequences and of whole words, as well as an unexpected strength in orthographic learning. Our findings underline the persistence of RAN-related reading problems, and raise questions about reading strategies in this group

The relationship between rapid naming and word spelling in English
A study of the concurrent relationships between naming speed, phonological awareness and spelling ability in 146 children in Year 3 and 4 of state funded school in SE England (equivalent to US Grades 2 and 3) is reported. Seventy-two children identified as having normal phonological awareness but reduced rapid automatized naming (RAN) performance (1 standard deviation below the mean) participated in the study. A group of 74 children were further identified. These children were matched on phonological awareness, verbal and non verbal IQ, and visual acuity but all members of this group showed normal rapid automatized naming performance. Rapid automatized naming made a significant unique contribution to spelling performance. Further analyses showed that the participants with low naming performance were significantly poorer spellers overall and had a specific difficulty in spelling irregular words. The findings support the view that rapid automatized naming may be indexing processes that are implicated in the establishment of fully specified orthographic representations
Exceeding the recruitment target in a primary care paediatric trial:an evaluation of the Choice of Moisturiser for Eczema Treatment (COMET) feasibility randomised controlled trial
BACKGROUND: Recruiting to target in randomised controlled trials of investigational medicinal products (CTIMPs) in primary care and paediatric populations is notoriously difficult. More evidence is needed for effective recruitment strategies in these settings. We report on the impact of different recruitment strategies used in the Choice of Moisturiser in Eczema Treatment (COMET) study – a feasibility trial comparing the effectiveness of four emollients for the treatment of childhood eczema – recruiting via general practitioner (GP) surgeries. METHODS: Initially, 16 GP practices invited potentially eligible children to take part in the trial by sending an invitation letter (self-referral pathway) or by consenting and randomising them into the study during a visit to the practice (in-consultation referral). Measures implemented during the study to maximise accrual included signing up six additional GP practices, increasing the upper age limit eligibility criterion from 3 to 5 years, and permitting healthcare professionals other than doctors to confirm participant eligibility. We used descriptive statistics and univariate linear regression models to explore associations with practice recruitment rates. RESULTS: A total of 197 participants were recruited, exceeding the target of 160. Of these, 107 children entered via self-referral and 90 by in-consultation pathways. Of the recruited population, 12.6 % were aged between 3 and 5 years (the raised upper age limit). The six additional practices contributed 37.4 % (40 of 107) of participants recruited by self-referral. Only almost one-third (18 of 56 [32.1 %]) of potential recruiting clinicians recruited one or more participants in-consultation, which was a more problematic pathway because of data verification issues. Three research nurses and a pharmacist from four practices recruited 48.9 % (44 of 90) of participants via this pathway. Univariate linear regression models showed no evidence of association between the number of children recruited via the self-referral pathway by practice and practice list size (p = 0.092) or practice deprivation decile (p = 0.270), but practice deprivation was associated with a higher number of children recruited in-consultation (p = 0.020) by practice. CONCLUSIONS: Self-referral and in-consultation recruitment yielded similar numbers, but the in-consultation pathway was more problematic. Future trials of this type should consider the condition, normal care pathway and number of potentially eligible children and be prepared to use multiple recruitment strategies to achieve recruitment targets.

An experimental comparison between rival theories of rapid automatized naming performance and its relationship to reading
Two studies investigated the degree to which the relationship between Rapid Automatized Naming (RAN) performance and reading development is driven by shared phonological processes. Study 1 assessed RAN, phonological awareness and reading performance in 1010 children aged 7-10 years. Results showed that RAN deficits occurred in the absence of phonological awareness deficits. These were accompanied by modest reading delays. In structural equation modeling, solutions where RAN was subsumed within a phonological processing factor did not provide a good fit to the data, suggesting that processes outside phonology may drive RAN performance and its association with reading. Study 2 investigated Kail's (1991) proposal that speed of processing underlies this relationship. Children with single RAN deficits showed slower speed of processing than closely matched controls performing normally on RAN. However, regression analysis revealed that RAN made a unique contribution to reading even after accounting for processing speed. Theoretical implications are discussed
Development of reading comprehension in bilingual and monolingual children—effects of language exposure
The current study aimed at investigating the performance of bilingual children with English as an additional language (EAL) on language and literacy measures compared to monolinguals across the first four years of primary school in the U.K. Moreover, it addressed whether bilinguals and monolinguals’ performance on reading comprehension was consistent with the Simple View of Reading. An additional area of interest was to examine the extent to which use of and exposure to both heritage and majority language affected the development of the children’s reading comprehension in both of their spoken languages. A total of forty bilingual and forty monolingual children were assessed in oral language skills and decoding in Year 1 and Year 3 in primary school. After one school year, they were assessed in oral language skills, decoding, and reading comprehension in Year 2 and Year 4. The results showed that the bilinguals performed better than the monolinguals in decoding in all years, suggesting that exposure to a first language with transparent orthography (Greek) may benefit the development of word reading skills. However, the bilinguals scored lower in oral language skills and reading comprehension than their monolingual peers. This finding underlined the significant role of oral language skills in the development of bilinguals’ reading comprehension. Both oral language skills and decoding contributed to reading comprehension in bilinguals but the effects of oral language skills on reading comprehension were stronger than the effects of decoding. Finally, we found that language use of the minority language outside the home could significantly predict reading comprehension in the minority language, underlining the importance of language exposure through complementary schools and other activities outside the home to the maintenance and development of the heritage language
