公正世界信念作为一种社会认知倾向,对于个体发展具有普遍影响,但是在学校情境中探索公正世界信念与学业成就的关系及影响机制的研究却很有限。本研究以郑州市两个区县的2584名初中一年级学生为被试,考察公正世界信念对其学业成就的影响,从班级生态环境的角度,探索个体对教师支持和班级公正的感知在二者之间的中介作用。结果发现:初中生的公正世界信念可显著预测其学业成就;在控制了性别、年龄后,学生的公正世界信念可分别通过对教师支持和班级公正的感知间接影响其学业成就,公正世界信念还可以通过感知的教师支持影响对班级公正的感知,进而影响学业成就的多重中介路径发挥作用。个体对班级教师支持和班级公正的感知是公正世界信念影响学业成就的重要途径。 相似文献

Which types of benefit finding in negative events central to identity lead to higher identity achievement? This study examined the relationships between the identity centrality of negative events, benefit finding, and identity achievement, with consideration of differences between benefit-finding domains. Participants included 245 undergraduates, who recalled a previous negative event and completed the Identity Scale, Centrality of Event Scale, and items regarding benefit finding. Path analysis showed that benefit finding regarding personal growth consistently correlated with identity achievement, while the effects of recognizing warmth in others were unstable depending on event category. The findings demonstrated the role of benefit finding regarding personal growth in promoting identity achievement and buffering the original adverse impact of negative events on identity. 相似文献

青年学生自信问卷的编制 总被引:8,自引:0,他引:8
自信是指对自己的信任,对自己身体、心理和社会性的信任,表现为有信心,不怀疑。为了编制青年学生自信问卷,首先采用开放式问卷对130名大学生和高中学生进行了调查,内容分析表明青年学生自信包含五类行为,在此基础上编制了青年学生自信预试问卷。391份有效问卷的探索性因素分析表明,青年学生自信问卷测查的是个五因素结构,包括才智自信、人际自信、品质自信、应对自信和成就自信。为了进一步检验青年学生自信问卷的构想效度,并考察其效标效度,1084名青年学生完成了该问卷和五项效标的测查。验证性因素分析支持青年学生自信问卷的结构,结合信度分析和多元回归分析的结果,表明青年学生自信问卷具有较好的信度与效度。 相似文献

David Hilbert’s early foundational views, especially those corresponding to the 1890s, are analysed here. I consider strong evidence for the fact that Hilbert was a logicist at that time, following upon Dedekind’s footsteps in his understanding of pure mathematics. This insight makes it possible to throw new light on the evolution of Hilbert’s foundational ideas, including his early contributions to the foundations of geometry and the real number system. The context of Dedekind-style logicism makes it possible to offer a new analysis of the emergence of Hilbert’s famous ideas on mathematical existence, now seen as a revision of basic principles of the “naive logic” of sets. At the same time, careful scrutiny of his published and unpublished work around the turn of the century uncovers deep differences between his ideas about consistency proofs before and after 1904. Along the way, we cover topics such as the role of sets and of the dichotomic conception of set theory in Hilbert’s early axiomatics, and offer detailed analyses of Hilbert’s paradox and of his completeness axiom (Vollständigkeitsaxiom). 相似文献

The predictive value of numerical magnitude comparison for individual differences in mathematics achievement 总被引:2,自引:0,他引:2

Although it has been proposed that the ability to compare numerical magnitudes is related to mathematics achievement, it is not clear whether this ability predicts individual differences in later mathematics achievement. The current study addressed this question in typically developing children by means of a longitudinal design that examined the relationship between a number comparison task assessed at the start of formal schooling (mean age = 6 years 4 months) and a general mathematics achievement test administered 1 year later. Our findings provide longitudinal evidence that the size of the individual’s distance effect, calculated on the basis of reaction times, was predictively related to mathematics achievement. Regression analyses showed that this association was independent of age, intellectual ability, and speed of number identification. 相似文献

Children and youth in neighborhood contexts 总被引:3,自引:0,他引:3
Neighborhoods are increasingly studied as a context where children and youth develop; however, the extent of neighborhoods' impact remains debatable because it is difficult to disentangle this impact from that of the family context, in part because families have some choice as to where they live. Evidence from randomized experiments, studies using advanced statistical models, and longitudinal studies that control for family characteristics indicates that neighborhoods do matter. In nonexperimental studies, small to moderate associations were found, suggesting that children and adolescents living in high-income neighborhoods had higher cognitive ability and school achievement than those living in middle-income neighborhoods, and children and adolescents living in low-income neighborhoods had more mental and physical health problems than those living in middle-income neighborhoods. The home environment has been shown to be partly responsible for the link between neighborhood and children's development. For adolescents, neighborhood effects are partially accounted for by community social control. Experimental studies in which families were randomly assigned to move to low-poverty neighborhoods from housing projects found larger neighborhood effects than nonexperi-mental research, particularly for boys' outcomes. Additional issues reviewed are relevant neighborhood characteristics, theoretical models explaining the pathways underlying neighborhood effects, methods for research assessing neighborhood processes, and policy implications. 相似文献

Concerns regarding American schools and mental health services for children abound, including inadequate educational achievement, school violence, over-referral to special education and disproportionate placement of minorities into special education, under-utilization of mental health services for children, and a poorly coordinated system of child mental health services. All of the above concerns share two common attributes: (a) they are statements regarding populations, rather than specific individuals; and (b) they are best addressed by changing system-wide elements of psychological service delivery. We argue that, although conceptualizing school psychology as primarily an indirect service specialty (e.g., J. Sch. Psychol. 28 (1990) 203) has advanced our thinking about effective service delivery, conceptualizing school psychological services from a public health perspective will provide an even broader framework that can increase both the efficacy and efficiency of school psychologists' work. 相似文献

We examined midlife educational, career, and family outcomes of women who attended prestigious women's colleges in the 1960s. One college had a coeducational learning environment (CLE), the other was a single-sex environment (SLE). We hypothesized that in CLEs, exposure to men's standards of achievement might have resulted in greater educational and career status outcomes but more discrimination; in SLEs, there might have been fewer opportunities to engage with men intellectually, which could lead to lesser educational and career status outcomes, but the environment might have felt more supportive. Graduates of both colleges were very accomplished 30 years after graduation; however, those who had experienced a CLE reported more sexism and more active involvement in the women's movement than SLE graduates. 相似文献

This study examines how several indicators of ability and achievement are associated with individual differences in preferences for job and organizational attributes. Results from a sample of 378 business and liberal arts students suggest that students with high cognitive ability and all types of high achievement place greater importance on interesting and challenging work than do other students. However, on other work attributes (e.g., job flexibility, pay practices, fast-track promotion systems), students with high cognitive ability and high academic achievement (i.e., grade point average) appear to have different preference patterns from those with high social achievement (e.g., extracurricular and leadership activities). Results are discussed in terms of implications for employers and future research. 相似文献
