The early identification of young children's special educational needs (SEN), as well as the development of specific strategies to support those children identified with special needs, are increasingly recognised as crucial to facilitating good adjustment to school and to ensuring that such children are helped to reach their full potential in education. Using a large national sample of young children in England whose developmental progress was followed up from pre‐school, this study investigates which child, family, home and pre‐school factors can be viewed as risk or protective factors for later SEN‐status at age 10. The experience of high‐quality pre‐school education is shown to reduce the likelihood of a child being identified as experiencing SEN in the long run. Teachers’ assessments of SEN are found to be strongly related to children's reading and mathematics attainment, but other factors also predict SEN, including a child's age within a year group. 相似文献

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions. 相似文献

OBJECTIVE: This study's aim was to examine variables associated with different short-term trajectories in multiply disadvantaged adolescent mothers by investigating antecedents and concomitants of parenting stress. METHOD: We followed 49 adolescent mothers (ages 14-18 at study outset) who were wards in Illinois foster care using a longitudinal correlational design. We examined whether parenting variables (childrearing beliefs, quality of parent-child interactions, and child abuse risk) and personal adjustment variables (emotional distress and social support) at initial assessment predicted parenting stress measured at follow-up (a mean of 22.5 months later). We also examined concurrent relationships between parenting stress and mothers' adaptive functioning in educational, social support, and childbirth areas at follow-up. RESULTS: We found that parenting variables, but not personal adjustment variables, predicted later parenting stress. Results also showed that current adaptive functioning was significantly related to parenting stress. Specifically, educational status and social support predicted concurrent parenting stress, whereas number of childbirths did not. CONCLUSIONS: These findings extend the small literature on the link between parenting difficulties and parenting stress to adolescent mothers in foster care. Parenting challenges, particularly as reflected in unrealistic childrearing expectations, appear to be markers for later parenting stress. Considering the longitudinal relationships observed, early and periodic assessment of adolescent mothers' parenting knowledge, skills, and interactions is recommended. Also, given that this study found concurrent social support and educational status to covary with current parental stress, these variables, and others for which they may serve as proxy, are implicated for careful monitoring. 相似文献
