This study sought to discover some of the causes of initial interset in and atrition from the natural sciences and engineering
among the students (N=5320) who entered four highly selective institutions in 1988, with particular attention to possible special causes for the
disproportionate attrition of women from science. Though a smaller proportion of women (35 percent) than men (49 percent)
were initially interested in science, gender added little to the prediction of such initial choice when preadmission measures
of developed abilities were taken into account in regression analysis. Of the group of 2,276 students initially interested
in science, 40 percent did not finally concentrate in science, and smaller proportions of women (48 percent) than of men (66
percent) persisted. The most significant cognitive, factor predicting these losses was low grades earned in science courses
taken during the first two years of study. With grades held equal, gender was not a significant predictor of persistence in
engineering and biology; gender added strongly to grades, however, as a factor associated with unusually large losses of women
from a category that included the physical sciences and mathematics. Responses to a questionnaire administered in the fall
of 1991 showed that science majors regarded their instruction as too competitive, with too few opportunities to ask questions,
taught by professors who were relatively unresponsive, not dedicated, and not motivating. Students who defected from science
did so largely because of the attraction of other fields, but many shared the criticism of overcompetitiveness and inferior
instruction, along with the view that the work was too difficult. Several items were about elements of classroom instruction
and atmosphere thought to be especially difficult for women (i.e., the chilly climate), but except for perceived competitiveness,
women did not rate their classroom experiences as being more unpleasant than did men.

The purpose of this article is to develop a statistical model that best explains variability in the number of school days suspended. Number of school days suspended is a count variable that may be zero-inflated and overdispersed relative to a Poisson model. Four models were examined: Poisson, negative binomial, Poisson hurdle, and negative binomial hurdle. Additionally, the probability of a student being suspended for at least 1 day was modeled using a binomial logistic regression model. Of the count models considered, the negative binomial hurdle model had the best fit. Modeling the probability of a student being suspended for at least 1 day using a binomial logistic regression model with interactions fit both the training and test data and had adequate fit. Findings here suggest that both the negative binomial hurdle and the binomial logistic regression models should be considered when modeling school suspensions. 相似文献

与目前运用单一方法的研究相比,多层混合法研究作为一种重要的研究范式,其研究结果可能因更严谨可靠而对政策和实践产生更大的影响。运用多层混合法不仅需要提升研究者的技术能力,还需要转变他们的思维方式。对大多数研究者来说,这可能是一个极大的挑战。当然,这并不是说所有的研究都应该寻求对他人的直接影响;相反,研究的目的各有不同。尽管如此,不同研究领域的研究者一致认为,教师课堂内外赖以生存的社会环境的生态具有不可预测性。对一项在英格兰实施的研究项目进行剖析,探讨多层混合法在教育研究中的应用,发现与单视角的量化研究、元分析或者纯质性研究相比,多层混合法可能提供更微妙的、更细颗粒度的、更严谨可信的、基于循证的领导力研究,从而更为全面地揭示校长如何通过领导力角色、领导行为实现并且保持学校的可持续发展。 相似文献

This 5-year longitudinal study investigated advanced theory-of-mind (AToM) development in 161 German 5- to 10-year-olds (89 females, 72 males). Core aspects of AToM developed nonlinearly, with children reaching a milestone at the age of 7 years, around when they attained the conceptual insight that mental states can be recursive. In late elementary school, a multicomponent battery was used. Performance on many aspects of AToM was predicted by information-processing skills (intelligence and language at 6 years), but not by the age when children acquired the basic conceptual insight; only some naturalistic, social-interpretative tasks were correlated with children’s age at acquisition. This study documents significant developmental progressions in middle-childhood AToM and suggests that different mechanisms may underlie diverse aspects of social cognition. 相似文献

AbstractIn this article, the author describes a lens for engaging in research and practice in urban education rooted in deep cultural understandings of the concept of building bridges and the impact of cultural agnosia. 相似文献
