For those who grew up in Britain in the latter half of the twentieth century, there is known to be a strong association between social class or family income and attending a private school. However, increasing private school fees and promotion of school choice in the state sector have potential implications for the predictors of participation in private schooling in the twenty-first century. In this article, through analysis of rich, longitudinal data from a recent, representative birth cohort study, we provide new evidence on this issue. Given the high and rising fees required to send a child to private school, one might think that the decision is entirely connected with financial resources. However, while these remain an important factor, we argue that other determinants are also important. In particular, we highlight the importance of parental values and geographical proximity to high-quality state school alternatives: a one standard deviation increase in levels of parental traditional values is associated with a 2.5 percentage point higher probability of their child attending a private school, while each minute of additional travel time to the nearest state school judged ‘Outstanding’ by England’s schools inspectorate is associated with a 0.2 percentage point higher probability of attending a private school. We also examine the characteristics of those who ‘mix and match’ state and private schooling, noting their similarity to private school attendees in terms of their values but lower levels of financial resources.  相似文献

The aim of the present study was to determine the effect of post-exercise ingestion of a unique, high molecular weight glucose polymer solution, known to augment gastric emptying and post-exercise muscle glycogen re-synthesis, on performance during a subsequent bout of intense exercise. On three randomized visits, eight healthy men cycled to exhaustion at 73.0% (s = 1.3) maximal oxygen uptake (90 min, s = 15). Immediately after this, participants consumed a one-litre solution containing sugar-free flavoured water (control), 100 g of a low molecular weight glucose polymer or 100 g of a very high molecular weight glucose polymer, and rested on a bed for 2 h. After recovery, a 15-min time-trial was performed on a cycle ergometer, during which work output was determined. Post-exercise ingestion of the very high molecular weight glucose polymer solution resulted in faster and greater increases in blood glucose (P < 0.001) and serum insulin (P < 0.01) concentrations than the low molecular weight glucose polymer solution, and greater work output during the 15-min time-trial (164.1 kJ, s = 21.1) than both the sugar-free flavoured water (137.5 kJ, s = 24.2; P < 0.05) and the low molecular weight glucose polymer (149.4 kJ, s = 21.8; P < 0.05) solutions. These findings could be of practical importance for athletes wishing to optimize performance by facilitating rapid re-synthesis of the muscle glycogen store during recovery following prolonged sub-maximal exercise.  相似文献

Phonological awareness (PA), phonological memory (PM), and phonological access to lexical storage (also known as RAN), play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPAs) in 147 3-, 4-, and 5-year-old children whose native language was Spanish. Confirmatory factor analysis (CFA) supported the validity of each PPA as separate from general cognitive ability and separate from each other. Moreover, structural equation modeling found RAN uniquely associated with knowledge of Spanish letter names and Spanish letter sounds. PA was found the best predictor of children’s ability to distinguish alphabetic text from nonalphabetic text. Finally, general cognitive ability was only indirectly associated with emergent literacy skills via PPAs. These results highlight the importance of PPAs in the early literacy development of native Spanish speaking preschool children.  相似文献

A sample of 187 female students, attending a sixth‐form study day on religious studies, completed a questionnaire containing four scales concerned with assessing: attitude towards theistic religion, attitude towards science, scientism and creationism. The data demonstrated a negative correlation between attitude towards religion and attitude towards science. However, this negative correlation was transformed into a positive correlation after taking into account individual differences in the students’ views about scientism and creationism. The implications of this finding are discussed in the context of the increasing support within society for the teaching of alternatives to evolution within the science curriculum. The authors argue both that it is important to challenge scientism by developing a better understanding of the role and limits of scientific methods, and that religious belief about creation should be recognised as essentially a claim about the ontological dependence of nature rather than about the details of its origins and development.  相似文献

This study reports findings on the relative effects from a yearlong secondary intervention contrasting large-group, small-group, and school-provided interventions emphasizing word study, vocabulary development, fluency, and comprehension with seventh- and eighth-graders with reading difficulties. Findings indicate that few statistically significant results or clinically significant gains were associated with group size or intervention. Findings also indicate that a significant acceleration of reading outcomes for seventh- and eighth-graders from high-poverty schools is unlikely to result from a 50 min daily class. Instead, the findings indicate, achieving this outcome will require more comprehensive models including more extensive intervention (e.g., more time, even smaller groups), interventions that are longer in duration (multiple years), and interventions that vary in emphasis based on specific students’ needs (e.g., increased focus on comprehension or word study).  相似文献

This paper highlights the differences and similarities between a Kindergarten outside Bremen in Lower Saxony, Germany and a Primary School Junior Infant Class in County Cork, Republic of Ireland. Both are concerned with the education of the young child but whereas the Kindergarten is attended by three to six year olds, the Junior Infant Class caters almost exclusively for four to five year old children.

A case study account of both groups is given and an analysis of the activities which took place in each using the ‘Target Child Observational Schedule’ [Sylva et al., (1980)] is presented in bar‐graph form.

The paper concludes that Erzieherinnen, Kinderpflegerinnen and Junior Infant Class teachers need to engage in more interaction with the children in order, in particular, to raise the frequency and quality of linguistic interaction. An increase in the structure of the children's play would help to enhance cognitive development.  相似文献

This study addressed the validity of distinguishing children with reading disabilities according to the presence or absence of discrepancies between intelligence test scores and academic achievement. Three definitions of reading disability were used to provide criteria for five groups of children who (a) met a discrepancy-based definition uncorrected for the correlation of IQ and achievement; (b) met a discrepancy-based definition correcting for the correlation of IQ and achievement; (c) met a low achievement definition with no IQ discrepancy; (d) met criteria a and b; and (e) met none of the criteria and had no reading disability. Comparison of these five groups on a set of 10 neuropsychological tests corrected for correlations with IQ showed that group differences were small and accounted for little of the variability among groups. These results question the validity of segregating children with reading deficiencies according to discrepancies with IQ scores.  相似文献

Abstract

The effects of augmented feedback on perceptions of ability (SPA), practice behaviors, and performance during motor skill instruction of a novel task were investigated. Fourth-grade students (N = 103) were randomly assigned to one of four conditions: (a) no feedback; (b) motivational feedback; (c) task feedback; or (d) motivation and task feedback. They then practiced simple and complex cupstacking skills. On a relatively simple task, the type of feedback did not have a significant effect on children's SPA, practice behaviors, or performance; but on a more complex task, differential effects of feedback were evident. Results indicate that informational feedback is an important factor in facilitating student engagement, fostering positive perceptions of ability, and ultimately improving performance on a challenging task.  相似文献

Improvements in running economy (RE) are thought to lead to improvements in running performance (P). Multiple interventions have been designed with the aim of improving RE in middle and long-distance runners. The aim of this study was to assess the effect of interventions of at least 2-weeks’ duration on RE and P and to determine whether there is a relationship between changes in RE (ΔRE) and changes in running performance (ΔP). A database search was carried out in Web of Science, Scopus and SPORTDiscus. In accordance with a PRISMA checklist 10 studies reporting 12 comparisons between interventions and controls were included in the review. There was no correlation between percentage ΔRE and percentage ΔP (r = 0.46, P = 0.936, 12 comparisons). There was a low risk of reporting bias but an unclear risk of bias for other items. Meta-analyses found no statistically significant differences between interventions and controls for RE (SMD (95% CI) = ?0.37 (?1.43, 0.69), 204 participants, p = 0.49) or for P (SMD (95% CI) = ?0.65 (?26.02, 24.72, 204 participants, p = 0.99). There is a need for studies of greater statistical power, methodological quality, duration and homogeneity of intervention and population. Standardised measures of performance and greater control over non-intervention training are also required.  相似文献
