Etiology of reading difficulties as a function of gender and severity

To test the hypothesis that the etiology of reading difficulties may differ for males and females in more severely impaired samples, reading performance data from monozygotic (MZ), same-sex dizygotic (DZ_ss), and opposite-sex dizygotic (DZ_os) twin pairs were analyzed using a model-fitting implementation of the DeFries-Fulker (DF) model (Purcell & Sham, 2003, Behavior genetics, 33, 271–278). Five non-independent samples were selected using cut-offs of −1 (N = 737 pairs), −1.5 (N = 654), −2 (N = 468), −2.5 (N = 335), and −3 (N = 198) standard deviations (s) below the mean composite reading score of control twins. Male/female gender ratios for children with reading difficulties were significantly higher than 1.0 for all five samples and increased as a function of severity (viz., 1.15, 1.17, 1.40, 1.61, and 1.88, respectively). When the DF model was fit to the data, estimates of heritability (h _g²) and shared environmental influences (c _g²) were not significantly different for males and females in any of the groups. Consequently, the most parsimonious model that provided a good fit to the data at all five levels of severity equated the heritabilities and shared environmental influences for males and females, and fixed the DZ_os coefficient of genetic relatedness at 0.5. Thus, these results provide no evidence for a differential etiology of reading difficulties as a function of gender in more severely impaired samples, and suggest that the same genetic and environmental influences contribute to reading difficulties in males and females, irrespective of severity.     

Differential genetic etiology of reading disability as a function of mathematics performance

In order to assess the etiology of reading disability as a function of mathematics performance, data from 168 monozygotic (MZ) and 127 same-sex dizygotic (DZ) twin pairs in which at least one member of each pair was reading-disabled were subjected to quantitative genetic analyses. MZ and DZ concordance rates for reading disability were computed for different levels of mathematics performance, and reading performance data were fitted to an extension of the basic multiple regression model for the analysis of selected twin data. Results of these analyses suggest that genetic factors may be especially salient as a cause of reading disability in children with borderline deficits in mathematics performance: thus, mathematics performance may be a valid dimension for diagnosing subtypes of reading disability.     

Mathematical ability of 10-year-old boys and girls: genetic and environmental etiology of typical and low performance

The genetic and environmental etiologies of 3 aspects of low mathematical performance (math disability) and the full range of variability (math ability) were compared for boys and girls in a sample of 5,348 children age 10 years (members of 2,674 pairs of same-sex and opposite-sex twins) from the United Kingdom (UK). The measures, which we developed for Web-based testing, included problems from 3 domains of mathematics taught as part of the UK National Curriculum. Using quantitative genetic model-fitting analyses, similar results were found for math disabilities and abilities for all 3 measures: Moderate genetic influence and environmental influence were mainly due to nonshared environmental factors that were unique to the individual, with little influence from shared environment. No sex differences were found in the etiologies of math abilities and disabilities. We conclude that low mathematical performance is the quantitative extreme of the same genetic and environmental factors responsible for variation throughout the distribution.     

Genetic and environmental bases of reading and spelling: A unified genetic dual route model

We develop and test a dual-route model of genetic effects on reading aloud and spelling, based on irregular and non-word reading and spelling performance assessed in 1382 monozygotic and dizygotic twins. As in earlier research, most of the variance in reading was due to genetic effects. However, there were three more specific conclusions: the first was that most of the genetic effect is common to both regular and irregular reading. In addition to this common variance evidence was found for distinct genes influencing the acquisition of a lexicon of stored words, and additional genetic effects influencing the acquisition of grapheme–phoneme correspondence rules. The third conclusion, from a combined model of reading and spelling, is that reading and spelling have a common genetic basis. Models that did not distinguish lexical and non-lexical performance fit significantly worse than dual route genetic models. An implication of the research is that models of reading, whether connectionist or dual-route, must allow for the genetic independence of neurological processes underlying the decoding of non-words and irregular words.     

Anxious girls and laid-back boys: teachers’ and study counsellors’ gendered perceptions of students

ABSTRACT

Efforts to reach gender equality in education in Finland have been extensive. Both teacher education and policy documents for schools have focused on gender equality and gender-neutral treatment of students. The aim of this study is to explore if and how these efforts are manifested in upper secondary school teachers’ and study counsellors’ perceptions of students’ self-belief, academic emotions, study habits and behaviour at school. Twenty-three interviews were conducted and analysed qualitatively through inductive content analysis. The results revealed that teachers and study counsellors perceive that girls’ low self-belief and high achievement expectations affected their academic performance, while boys’ insecurity or need for support was rarely mentioned. The teachers ascribed the students several gender-stereotypical attributes: girls were perceived as diligent and hard-working while boys were perceived as being indifferent towards school and achievements. The implications of these results for students’ self-belief and for teacher education are discussed.     

Phonological basis in reading disability: A review and analysis of the evidence

Poor readers are known to do consistently worsethan their normal reading peers on tasks ofphonological processing. They are characterizedby their difficulties in printed wordrecognition, phonological awareness andphonological decoding. An increasing body ofevidence points to deficits in speechperception as a source of subtle but ramifyingeffects in reading impaired children andadults. These deficits may be traced to poorlycoded phonological representations. Thisarticle will attempt to explain poor readers'difficulties in phonological coding by drawingon a gestural account speech development.Implications of this approach for readingintervention will be presented.     

Differential social and political influences on girls and boys through education out of doors in the United Kingdom

Abstract

The way the outdoors was used for educational purposes was determined by the need for young men to be made fit for war and service in the British Empire, the need to improve the physical health of children from industrial conurbations and the preoccupation of those in authority with the notion of adolescence as a problem, especially the anticipated fear of juvenile delinquency. In the 1950s and early 1960s, when there was a significant increase in the use of the outdoors in education, much of the provision reflected the earlier emphasis on character training and “manly” virtues. The suggestion is made that this was due, in part at least, to the role played by a number of charismatic and influential figures and to continued sensitivity to social, political and military factors.     

Reading aloud in 19th century England: some evidence from Victorian fiction

ABSTRACT

Victorian fiction can provide a valuable source of information about society by virtue of its topicality and realistic techniques, influenced by contemporary journalism. In particular, the novels of Charles Dickens and Thomas Hardy throw light on literacy practices, including reading aloud. The higher the literacy levels of the novels’ characters, the less reading aloud is reported; and as literacy becomes more widespread through the 19th century, it is commented on increasingly less. Significantly, when instances of reading aloud are depicted, they fulfil purposes that seem to correspond with recognisable present-day scenarios, in which the power of the spoken word resonates.     

Computer-Assisted Tutoring in Success for All: Reading Outcomes for First Graders

Abstract

This article presents a randomized experiment evaluating a computer-assisted tutoring program. The software program, Alphie's Alley, provides reading tutors with assessment and planning tools and performance support. It provides students with animated presentations and engaging activities. In a yearlong study involving 25 schools using the Success for All reading program, 412 low-achieving first graders were randomly assigned to be tutored daily for 20 min with or without Alphie's Alley. Tutors were also randomly assigned. On individually administered reading measures, controlling for pretests, there were no significant differences overall, but among students with tutors rated as “fully implementing,” those who experienced Alphie's Alley scored significantly better on three of four measures. These results suggest that if well implemented, technology that enhances the performance of tutors has promise in improving the reading performance of at-risk children.     

Gender differences in reading: Examining text-based interest in relation to text characteristics and reading comprehension

Reading is a key competence for knowledge acquisition and learning processes. One important source of reading motivation is interest. Even though students' text-based interest often differs by gender, it remains unclear which text factors underlie these differences and whether text-based interest relates to reading comprehension among boys and girls. In a sample of 514 elementary students (47.2% girls), this study examined whether text topic, protagonists' gender, and text difficulty affect boys' and girls' text-based interest and whether interest and reading comprehension are intertwined. Based on a repeated within-subject design using fourteen narrative texts, the results indicated that boys' interest was higher in texts with male-attributed topics, male protagonists, and in more difficult texts. In contrast, girls’ interest was only affected by text difficulty. Text-based interest and reading comprehension were significantly related, albeit stronger for boys than for girls. The findings are discussed regarding future implications for research and educational practice.     

Buffering boys and boosting girls: The protective and promotive effects of Early Head Start for children's expressive language in the context of parenting stress

Children's characteristics, including gender, influence their development by eliciting differential responses from their environments, and by influencing differential responses to their environments. Parenting-related stress, associated with poverty environments, negatively influences children's language, likely through its impact on parent–child interactions, but may impact boys’ and girls’ development differently. Early intervention represents one tool for supporting development in at-risk toddlers, but gender-differences in effects of intervention are rarely described. The current studies assessed the effects of Early Head Start (EHS) on children's productive vocabulary in the context of parenting stress and examined gender differences in program effects on vocbulary. Data were from the national EHS Research and Evaluation (EHSRE) study (Study 1, N = 3001), and from a dataset associated with one EHSRE site (Study 2, N = 146) where additional data on productive vocabulary were collected. Study 1 found that at 24 months of age, the EHS program protected girls’ productive vocabulary from the negative effects of parenting stress, but had little impact on boys’ vocabulary. In Study 2, the local EHS site promoted girls’ vocabulary development over time from 14 to 36 months despite the negative effects of parenting stress, and protected boys’ vocabulary from the negative parenting stress effects. These results suggest differential ways in which at-risk toddlers are affected by early intervention.

Reading development and dyslexia in a transparent orthography: a survey of Spanish children

Spanish-speaking children learn to read words printed in a relatively transparent orthography. Variation in orthographic transparency may shape the architecture of the reading system and also the manifestation of reading difficulties. We tested normally developing children and children diagnosed with reading difficulties. Reading accuracy was high across experimental conditions. However, dyslexic children read more slowly than chronological age (CA)-matched controls, although, importantly, their reading times did not differ from those for ability-matched controls. Reading times were significantly affected by frequency, orthographic neighbourhood size and word length. We also found a number of significant interaction effects. The effect of length was significantly modulated by reading ability, frequency and neighbourhood. Our findings suggest that the reading development of dyslexic children in Spanish is delayed rather than deviant. From an early age, the salient characteristic of reading development is reading speed, and the latter is influenced by specific knowledge about words.     

The etiology of mathematical self-evaluation and mathematics achievement: understanding the relationship using a cross-lagged twin study from age 9 to 12

The genetic and environmental origins of individual differences in mathematical self-evaluation over time and its association with later mathematics achievement were investigated in a UK sample of 2138 twin pairs at ages 9 and 12. Self-evaluation indexed how good children think they are at mathematical activities and how much they like those activities. Mathematics achievement was assessed by teachers based on UK National Curriculum standards. At both ages self-evaluation was approximately 40% heritable, with the rest of the variance explained by non-shared environment. The results also suggested moderate reciprocal associations between self-evaluation and mathematics achievement across time, with earlier self-evaluation predicting later performance and earlier performance predicting later self-evaluation. These cross-lagged relationships were genetically rather than environmentally mediated.     

Risk for reading disability as a function of parental history in three family studies

Inverse Bayesian analyses were applied to data from three large family studies of reading disability to estimate the posterior probability that an offspring will be affected, given that a parent reported a history of learning problems. Prior analyses presented elsewhere (Pennington et al., 1990), suggest that family transmission in these three studies is consistent with major gene or polygene influence. Posterior probability rates are presented in this paper for male to female sex ratios of 3.5:1 and 1:1, with population incidences estimated at 0.05 and 0.10. Results indicate that offspring risk rates are significantly elevated if a parent reports a history of RD. Specifically, an offspring's risk was increased 2 to 80 times over population expectancies when there was an affected parent. While the posterior probabilities and relative risk rates were fairly similar across studies, there was also some variation, which may reflect the different genetic mechanisms operating in these families. This study concludes that both absolute and relative risks are sufficiently increased in families with RD parents to warrant use of family history as a component in clinical evaluation. It is also evident from these results that consideration of the apparent mode of genetic transmission in families may provide even better information as to offspring risk, when family history is obtained.     

Sound Reading and Reading Sounds: The Case for Phonemic Awareness

The National Reading Panel (NRP) issued a Congressional mandated report to identify key skills and methods related to the development of successful reading skills. One of the first of identified skills is phonemic awareness. This column addresses this area of reading instruction and provides suggestions for literature to be shared with young readers and listeners that support phonemic awareness. Fifteen children’s books are reviewed and recommended.

Telephone Testing and Teacher Assessment of Reading Skills in 7-year-olds: I. Substantial Correspondence for a Sample of 5544 Children and for Extremes

Many research questions require the assessment of reading in large samples of children. We compared two nonconventional procedures for early reading assessment: test administration by telephone, and teacher assessment. Five thousand five hundred and forty four children participating in a longitudinal twin study were assessed by telephone using the Test of Early Word Reading Efficiency, and by their teachers using the UK National Curriculum criteria. A correlation of 0.69 was obtained between the TOWRE and Teacher Assessment for Reading. There was also good agreement between the two procedures for identification of children at the lower extreme. Both appear to be practical and valid for research studies.     

Determinants of schooling for boys and girls in Nigeria under a policy of free primary education

This paper adds a measure of school costs to the model of determinants of schooling. Costs are estimated with controls for selection into school and the possibility of receiving free primary education (FPE). Controlling for costs, household wealth has a large, positive effect on primary school attendance with greater income elasticity for girls than boys. Girls’ attendance also depends on opportunity costs generated by providing child care for younger siblings and living on a family farm. Policies that increase household resources and reduce opportunity costs are recommended to complement free primary education.
