Generic sentences (e.g., Birds lay eggs) convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of morphosyntactic cues--in particular, on whether children can (a) interpret indefinite singular noun phrases (e.g., a strawberry) as generic and (b) use a verb's tense and aspect (e.g., A bat sleeps/slept/is sleeping upside down) to determine whether its subject noun phrase is generic. Children demonstrated sensitivity to both cues. Thus, solving the in-principle problem of identifying generics may not be beyond the reach of young children's comprehension skills. 相似文献

The Vanderbilt Assessment of Leadership in Education (VAL-ED) provides educators with a tool for principal evaluation based on principal, teacher, and supervisor reports of principals’ learning-centered leadership. In this study, we conduct a known group analysis as part of a larger argument for the validity of the VAL-ED in US elementary and secondary schools. We asked superintendents to select the principals in their district who they believe in performance of their duties are in the top 20 % and the bottom 20 %. We ask how accurately VAL-ED scores can identify membership of the two known groups. Using a discriminant analysis, the VAL-ED places principals in the superintendent groups, on average, 70 % of the time for both elementary and secondary schools. Placement accuracy is greater for the top group than the bottom group. 相似文献

The purpose of this study was to determine which family child care providers seek training, which providers drop out of training, and the effects of training on the quality of care offered by providers. One-hundred thirty family child care providers in three communities who enrolled in Family-to-Family training participated in the study. A comparison group consisted of 112 regulated providers in those same communities who were not involved in the training program under investigation. Each provider was observed for 3 hrs, was interviewed, and completed questionnaires. Providers in training were observed prior to training and 6 months afterwards. Results revealed that providers who sought training were very similar to typical regulated providers. Providers who dropped out of training were less experienced and used fewer business and safety practices than providers who completed it. Training increased global quality in two out of three sites, but did not affect process quality. Of 95 providers, 18 made observable (as opposed to statistically significant) improvements in quality following training, and 9 decreased in quality. These data are interpreted with respect to family child care training policies and practices. 相似文献

In the field of developmental social psychology there is a consensus concerning the social nature of intelligence. In spite of the important empirical investigations in this field over the last fifteen years, the influence of the quality of a relationship on joint problem-solving and learning is still poorly understood. This explorary study investigated the influence of socio-affective context on the interactive modalities surrounding social problem-solving discussions conducted with 32 dyads of 8-year-old Swiss francophone children. Sociometric interviews with children and teachers were carried out to identify the following naturally-ocurring socio-affective contexts: reciprocal friendship (RF), asymmetrical friendship (AF) and reciprocal absence of friendship (“reciprocal non-friendship” RNF; excluding enemies). Comparisons of verbal exchanges and dyadic performance across the three groups suggests that reciprocal friendship facilitates collaboration and the organization of collective work. Two rival hypotheses opposing socio-affective proximity (reciprocal friendship) and socio-affective distance (asymmetrical friendship and reciprocal absence of friendship) are discussed with respect to the influence of social interactions on social problem-solving. 相似文献

Fourth-grade follow-up achievement outcome data of placed and nonplaced transition extra-year school readiness samples indicate a nonsignificant standardized score difference, as noted in the second-grade findings. New analysis of correlation data indicates that within-sample age distribution shows a positive correlation with standardized achievement test scores in a study sample of non-at-risk students nonretained or recommended for retention. This age-achievement correlation is strong in kindergarten, with decreased effects by second and fourth grade. Four study samples of at-risk students (students retained in a transition extra-year school readiness program, students recommended and eligible for such placement but not placed, students retained in kindergarten through second grade, and students held out of school prior to kindergarten) reflect moderate inverse (negative) correlations between age and achievement test scores, with increasing inverse effects in fourth grade. Effect analysis and implications are discussed. © 1996 John Wiley & Sons, Inc. 相似文献

The language children hear presents them with a multitude of co-occurrences between words and things in the world, and they must repeatedly determine which among these manifold co-occurrences is relevant. Social factors—such as cues regarding the speaker's referential intent—might serve as one guide to whether word-object covariation should be registered. In 2 studies, infants (15–20 months and 18–20 months in Studies 1 and 2, respectively) heard novel labels at a time when they were investigating a single novel object; in one case the label was uttered by a speaker seated within the infant's view and displaying concurrent attention to the novel toy (coupled condition), whereas in the other case the label emanated from a speaker seated out of the infant's view (decoupled condition). In both studies, subsequent comprehension questions indicated that infants of 18–20 months registered a stable link between label and object in the coupled condition, but not in the decoupled condition, despite the fact that covariation between label and object was equivalent in the 2 conditions. Thus, by 18–20 months children are inclined to establish a mapping between word and object only when a speaker displays signs of referring to that object. 相似文献

This study employed a national sample of college students who initially aspired to be, or later became, physicians to determine the influence of precollege characteristics, college origins, and the academic and social experience of college on the likelihood of becoming a physician. Estimates of a 14-variable causal model indicated that the major direct effects on attainment were attributable to college characteristics and the academic experience of college. Net of other causes, the selectivity/prestige of the undergraduate institution attended, collegiate academic achievement, and majoring in the physical or life sciences each had significant direct effects on becoming a physician. The direct positive influence of college quality, however, was partially counterbalanced by its negative indirect effect. Moreover, the greatest advantage in attending an elite institution accrued to those students with relatively high levels of academic performance. As academic performance declined, so did the positive effect of college quality. The effects of precollege characteristics on becoming a physician were largely indirect, mediated by the student's college experience. Net of other factors, women were no less likely than men to become physicians, but being female had a significant negative indirect effect. Conversely, secondary school achievement did not directly influence attainment but did have a large positive indirect influence.An earlier version of this paper was presented at the annual meeting of the Association for the Study of Higher Education, San Diego, February, 1987. 相似文献
