A doula and expectant mother's view of birth is forever changed when she sees a midwife simply place a newly born child below her mother at the moment of birth. The pause that the mother experiences in this moment as she studies, touches, and claims her child prompts the author to reflect in this guest editorial on ways we might be disturbing the natural sequence of birth as we deliver babies directly to their mothers' chests.  相似文献

Cognitive abilities as well as math fluency play an important role in mathematical skills. Understanding the relationship between cognitive abilities and mathematical skills is imperative to teaching effective arithmetic skills. The present study aimed to investigate the relationship between cognitive ability and math fluency with 38 first and second grade elementary aged children. Results demonstrate that preoperational children lacked the speed of concrete operational children but achieved comparable levels of accuracy when completing arithmetic problems.  相似文献

This paper draws on a four-year longitudinal ESRC funded project examining learning experiences of disabled students in higher education in four universities. The focus here is on institutional responses to the demands of audit culture and legislation in relation to making reasonable adjustments for students with impairments. The data comes from institutional documents and face-to-face interviews with key informants within the institutions. The findings indicate that quality assurance regimes and legislation have had some positive effect on improving access for disabled students; however, local factors and type of institution also have a major impact on the way that national policies are expressed in particular contexts.  相似文献

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions, visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended on the quality of the food available in a particular location. When it was possible for the rats to observe each other on the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated with memory for the behavior of another rat to determine spatial choice  相似文献

This study utilized early reading assessment data from a randomized trial of 210 urban and rural schools in Texas to examine contextual effects on risk prediction in first and second grade. The primary objective was to examine the roles of (a) individual differences, (b) the grade 1 classroom, and (c) the pairing of first and second grade teachers in determining grade 2 outcomes in word reading and fluency. A second objective was to investigate whether the administration format of the assessment (paper, paper plus desktop, handheld plus desktop) or the level of teacher support (web mentoring, no mentoring) moderated the prediction. These moderator variables proved not to be significant. Subsequent analyses found that a combination of student pretest and mean of pretest classroom was a better predictor than student pretest alone. Additionally, the effect of student scores varied by teacher-pair. On average, intraclass correlations (ICCs) ranged from 6% to 17%. Differences in ICCs at the classroom level were much greater than at the school level, and differences in urban schools were twice that of rural schools.  相似文献

In eighteenth-century France, geodesy (the measure of the earth's shape) became an arena where mathematics and narrative intersected productively. Mathematics played a crucial role not only in the measurements and analysis necessary to geodesy but also in the narrative accounts that presented the results of elaborate and expensive expeditions to the reading public. When they returned to France to write these accounts after their travels, mathematician-observers developed a variety of ways to display numbers and mathematical arguments and techniques. The numbers, equations, and diagrams they produced could not be separated from the story of their acquisition. Reading these accounts for the interplay of these two aspects--the mathematical and the narrative--shows how travelers articulated the intellectual and physical difficulties of their work to enhance the value of their results for specialist and lay readers alike.  相似文献

In order to determine the role of time limits on both test performance and test validity, we asked approximately 300 volunteers–prospective graduate students–to each write two essays–one in a 40-minute time period and the other in 60 minutes. Analyses revealed that, on average, test performance was significantly better when examinees were given 60 minutes instead of 40. However, there was no interaction between test-taking style (fast vs. slow) and time limits. 'That is', examinees who described themselves as slow writers/test takers did not benefit any more (or any less) from generous time limits than did their quicker counterparts. In addition, there was no detectable effect of different time limits on the meaning of essay scores, as suggested by their relationship to several nontest indicators of writing ability.  相似文献

The developmental status and social–emotional functioning of young children who are homeless has received inadequate attention in spite of high rates of homelessness among families with young children and the potentially negative impact of homelessness and associated stressors on children’s well-being. The aim of this study was to gain understanding of homeless children’s social–emotional adjustment and their functioning in language, motor, and cognitive skills. We also examined gender and age differences in those areas of development. The sample included 328 children residing with their parents in one of 11 emergency shelter or transitional housing programs for families who were experiencing homelessness in a central North Carolina county. Child case managers administered the Brigance Early Childhood Screen II and the Ages and Stages Questionnaire: Socioemotional form in the shelter setting. Findings indicated variability in competence among the children, with some children performing above average on the developmental screening and demonstrating few social–emotional problems. However, developmental scores for overall functioning of the sample were significantly below the norming group, with particularly low functioning in language and communication skills. Parents of 24.8 % of the children had substantial concerns about their children’s mental health status. Although there are individual differences in adjustment of children experiencing homelessness, results support wide-scale screening and access to early intervention for these vulnerable children. Future investigations could be directed to identifying factors associated with resilience among children without homes.  相似文献
