Postsecondary schools have traditionally relied on admissions tests such as the SAT and ACT to select students. With high school achievement assessments in place in many states, it is important to ascertain whether scores from those exams can either supplement or supplant conventional admissions tests. In this study we examined whether the Arizona Instrument to Measure Standards (AIMS) high school tests could serve as a useful predictor of college performance. Stepwise regression analyses with a predetermined order of variable entry revealed that AIMS generally did not account for additional performance variation when added to high school grade-point average (HSGPA) and SAT. However, in a cohort of students that took the test for graduation purposes, AIMS did account for about the same proportion of variance as SAT when added to a model that included HSGPA. The predictive value of both SAT and AIMS was generally the same for Caucasian, Hispanic, and Asian American students. The ramifications of universities using high school achievement exams as predictors of college success, in addition to or in lieu of traditional measures, are discussed.  相似文献

Genetic change as well as continuity was investigated within the domains of temperament, emotion, and cognition/language for 200 pairs of twins assessed at 14 and 20 months of age in the laboratory and home. The second year of life is marked by change rather than continuity: correlations from 14 to 20 months averaged about .30 for observational measures of temperament and emotion, about .40 for language measures, and about .50 for mental development. 2 types of genetic change were examined: changes in the magnitude of genetic influence (heritability) and genetic contributions to change from 14 to 20 months. In general, heritability estimates were similar at 14 and 20 months. Evidence for genetic influence on change from 14 to 20 months emerged for several measures, implying that heritability cannot be equated with stability. Analyses of continuity indicated that genetic factors are largely responsible for continuity from 14 to 20 months.  相似文献

This study investigated whether orthographic consistency and individual learner differences including working memory (WM), first language (L1) background, and second language (L2) proficiency affect Chinese L2 learners’ literacy acquisition. Seventy American college students in beginning or intermediate Chinese classes participated in a character learning-and-reading experiment, and completed WM tasks and an L2 proficiency test. In the learning phase of the experiment, participants were asked to master 18 unfamiliar Chinese characters of three levels of consistency—consistent, semi-consistent, and inconsistent. Then in the transfer test of the experiment, participants read 60 novel, artificial characters analogous to the learned characters. Significant consistency effects for learning and reading new characters were found, with no effects of WM and L1. In particular, an interaction effect between consistency and L2 proficiency found in the learning phase indicated that participants with higher L2 proficiency learned the fully consistent characters better and faster than those with lower proficiency. These results suggest that L2 proficiency facilitates awareness of consistency, enabling learners to learn novel characters faster and more accurately. The findings of this study are compared with the character acquisition of beginning L1 Chinese readers and with L2 learners’ acquisition of other types of characters.  相似文献

School responses to the Prevent agenda have tended to focus primarily on ‘safeguarding’ approaches, which essentially perceive some young people as being ‘at risk’ and potentially as presenting a risk to others. In this article, we consider evidence from secondary school students who experienced a curriculum project on terrorism, extremism and radicalisation. We argue that a curriculum response which addresses the acquisition of knowledge can build students’ critical capacity for engagement with radicalisation through enhanced political literacy and media literacy. We further argue this represents a genuinely educational response to Prevent, as opposed to a more restrictive securitised approach.  相似文献

Temperament and Craniofacial Variation in the First Two Years   总被引:2,自引:0,他引:2  
High levels of circulating glucocorticoids in fetal animals are associated with inhibited development of the lateral processes of the maxilla, or upper jaw, as these bones grow toward midline union early in gestation. This inhibition can prevent fusion and lead to the formation of cleft palate. Mouse strains are differentially susceptible to this effect. These strains also differ in behavioral and physiological characteristics that are analogous to those we have observed in 2 temperamental groups of children, analogies that prompted the current study. Infant temperament was assessed using behavioral observation at 4 months, and the ratio of upper facial width (bizygomatic breadth across the cheekbones) to height of the head and face was measured at 14 and 21 months. High reactive 4-month-old infants, who are predisposed to becoming timid, inhibited toddlers, had smaller bizygomatic ratios (narrower faces) at both 14 and 21 months compared to their low reactive peers, who are predisposed to becoming outgoing, uninhibited children. Differences in facial width were modest though significant and not attributable to overall stature.  相似文献

Previous research in both humans and nonhuman primates suggests that subtle asymmetries in tympanic membrane (TM) temperatures may be related to aspects of cognition and socioaffective behavior. Such associations could plausibly reflect lateralities in cerebral blood flow that support side-to-side differences in regional cortical activation. Asymmetries in activation of the left and right frontal cortex, for example, are correlates of temperamental differences in child behavior and markers of risk status for affective and anxiety disorders. Tympanic membrane temperatures might thus reflect the neural asymmetries that subserve individual differences in temperament and behavior. This report merged findings from four geographically and demographically distinctive studies, which utilized identical thermometry methods to examine associations between TM temperature asymmetries and biobehavioral attributes of 4- to 8-year-old children (N = 468). The four studies produced shared patterns of associations that linked TM temperature lateralities to individual differences in behavior and socioaffective difficulties. Warmer left TMs were associated with "surgent," affectively positive behaviors, whereas warmer right TMs were related to problematic, affectively negative behaviors. Taken together, these findings suggest that asymmetries in TM temperatures could be associated with behavior problems that signal risk for developmental psychopathology.  相似文献
