Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N = 8,920, Mage = 97.6 months), (b) multiple measures of EF, academic achievement, and behavior, and (c) extensive statistical control including for domain-specific and domain-general lagged dependent variables. All three measures of EF—working memory, cognitive flexibility, and inhibitory control—positively and significantly predicted reading, mathematics, and science achievement. In addition, inhibitory control negatively predicted both externalizing and internalizing problem behaviors. Children's EF constitute promising targets of experimentally evaluated interventions for increasing academic and behavioral functioning. 相似文献

ABSTRACTThe purpose of this study was to explore the respiratory response of acute interval and continuous exercise (CE) of low and high intensity. Fourteen recreational athletes (7 men and 7 women; VO2max = 35.7 ± 6.1 mlkg–1min–1) performed a bout of continuous and a bout of interval exercise (IE) both consisted of 5-min cycling at low intensity [80% of the power output (W) of the predetermined gas exchange threshold (GET) (80%WGET)] and 5-min cycling at high intensity {WGET plus the work rate corresponding to 50% of the difference between peak power output (PPO) at oxygen uptake (VO2max) test and the WGET [WGET + 0.50 Δ(PPO – WGET)]}. CE compared to IE induced significant higher heart rate and ventilation as well as significant higher levels of mouth occlusion pressure for 0.1 s (P0.1) (P < 0.05) during low and high intensities. Our results indicate that CE stimulates respiration more than IE when the exercise is performed at the same relative intensity. 相似文献

Examining the Psychometric Quality of the National Board for Professional Teaching Standards Early Childhood/Generalist Assessment System* 总被引:1,自引:0,他引:1

The purpose of the study was to examine the psychometric quality of the National Board for Professional Teaching Standards (NBPTS) Early Childhood/Generalist assessment system. Rating data from the 1997–1998 assessment were analyzed using the FACETS (Linacre, 1998) computer program. The assessment system's 10 exercises work together to define a unidimensional accomplished teaching variable. There is little evidence of multidimensionality in the data, and none of the exercises appear to function in a redundant manner. The exercise set succeeds in defining several statistically distinct levels of accomplished teaching among the candidates. Overall, most candidate rating profiles show consistent performance across the exercises. While assessors differed somewhat in severity, most used the 12-point rating scale consistently. Although the range in assessor variability tends to be moderate, assessor severity does influence the number of candidates that can bank individual exercises. (If a candidate's total scaled score does not meet or exceed the NBPTS performance standard of 275, the candidate can bank scores on exercises in which the candidate received a final score of 2.75 or greater. If the candidate reapplies for certification in the next three years, the candidate does not have to retake banked exercises.) 相似文献

A significant historical role in the development of competence-based vocational qualifications in England and Wales is customarily ascribed to the 1985 to 1986 Review of Vocational Qualifications (RVQ), the body which invented the National Vocational Qualification (NVQ). This paper analyses the RVQ's internal debates. The paper demonstrates that the RVQ proposed only the general principles of a structure and an administration for a reformed vocational qualifications system. The RVQ did not address in detail either the definition of occupational competence or the curriculum and assessment models to be embodied in the NVQ. In the light of this analysis, the paper re-evaluates the role of the RVQ in the development of competence-based vocational qualifications, and suggests some potentially fruitful areas for future research. 相似文献
