This study was designed to examine the effects of adults' labeling and use of social groups on preschool children's intergroup attitudes. Children (N=87, aged 3-5) attending day care were given measures of classification skill and self-esteem and assigned to membership in a novel (red or blue) social group. In experimental classrooms, teachers used the color groups to label children and organize the classroom. In control classrooms, teachers ignored the color groups. After 3 weeks, children completed multiple measures of intergroup attitudes. Results indicated that children in both types of classrooms developed ingroup-biased attitudes. As expected, children in experimental classrooms showed greater ingroup bias on some measures than children in control classrooms.  相似文献

This is a study of the costs of instruction in a large public research university. It departs from other work on instructional costs in its attempt to draw inferences about the economic costs of incremental or marginal enrollments. Focusing on graduate education, we examine how the costs directly facing faculty differ from those incurred by the institution's administration and legislature as reflected in the budgetary rewards for instruction. These cost differences provide the wherewithal for a university to carry out basic research and other important functions that lack a paying clientele. The study also explores the roles of economic costs in the institution's pricing of graduate education.  相似文献

To infer the sophistication ofepistemic thinking in a sample of undergraduatestudents, 25 participants completed afree-response task in which they were asked togive reasons for their agreement ordisagreement with a small number of beliefsabout the role of tutorials and of tutors ingaining knowledge. Responses were analysedaccording to King and Kitchener's (1994) stagesof reasoning, revealing that the justificationsoffered were either at the stages ofpre-reflective or quasi-reflective thinkingwith none exhibiting reflective thinking. Thefindings have two main pedagogicalimplications: first that good teaching beunderstood not as a set of performance skillswhich may only be opportunistically related tostudents' extant conceptualisations but as thelocus through which students confront their ownepistemic beliefs. A second implication isthat to extend students' reasoning, teachingpractices must focus explicitly on thedifficult issue of what counts as evidence.  相似文献

This study examined the feeling state content of 3- and 4-year-olds' narratives. Four times throughout the school year, each child was paired with a familiar adult and provided an opportunity to talk with the adult about his/her day. Children's narratives were then coded for their feeling state content. Results revealed that children talk a great deal about affiliation, that sex differences emerge only in the context of interactive talk between adults and children, and that older children talk more about emotions than younger children when speaking spontaneously, but that these differences disappear when adults are able to provide “scaffolding” to the younger, less experienced, children.  相似文献

Ryan RM 《Child development》2012,83(3):1085-1101
Using data from the Fragile Families and Child Well-Being Study, the present study tested whether the benefits of a marital birth for early child development diminish as parents' risk of having a nonmarital birth increases (N = 2,285). It was hypothesized that a child's likelihood of being born to unmarried parents is partly a function of father characteristics that predict his capacity to promote child development. Results partially supported hypothesis. A positive association emerged between parental marriage and cognitive outcomes at age 3 only for children whose parents were likely to be married at the child's birth, suggesting average differences between children in married and unmarried families may overestimate the benefit of marriage in subpopulations most impacted by nonmarital birth.  相似文献

Analysis of Differential Item Functioning in the NAEP History Assessment   总被引:1,自引:0,他引:1  
The Mantel-Haenszel approach for investigating differential item functioning was applied to U.S. history items that were administered as part o f the National Assessment o f Educational Progress, On some items, blacks, Hispanics, and females performed more poorly than other students, conditional on number-right score. It was hypothesized that this resulted, in part, from the fact that ethnic and gender groups differed in their exposure to the material included in the assessment. Supplementary Mantel-Haenszel analyses were undertaken in which the number o f historical periods studied, as well as score. was used as a conditioning variable. Contrary to expectation, the additional conditioning did not lead to a reduction in the number o f DIF items. Both methodological and substantive explanations for this unexpected result were explored.  相似文献

The request to evaluate a nontraditional degree program sounds simple enough. But what does it mean “to evaluate the program?” This article identifies twelve major areas seeming to require evaluative attention according to the perspectives of a number of different groups of people. In addition to identifying these areas, the study suggested priorities for the areas in terms of their long-term, overall importance in a complete evaluation plan and their immediate or short-term importance in the early stages of program implementation.  相似文献
