The main concern of this paper is the decision making of young people from lower social class backgrounds about whether or not to participate in higher education. In the light of recent reforms of student funding and renewed efforts to widen participation in British higher education, an examination is made of the factors influencing the choices made by young people close to the time of making application for entry. Drawing on the findings of a research study undertaken in 2000 and conducted with recent and prospective undergraduate entrants, a contemporary perspective is offered on the issues facing different groups of young people from disadvantaged backgrounds. By way of conclusion, consideration is given to the need for improved information sources to guide young people in their decisions. 相似文献

One hundred and thirty-two 10th graders performed either a conjunetive or biconditional rule task in one of six conditions defined by a 2 (tasks: attribute-identification versus rule-learning) by 3 (memory aids: 0 versus 3 versus 6) factorial design. Learners' attribute-identification was facilitated when six memory aids were made available, especially given the biconditional rule, but not when three aids were available. This effect was attributed to the facilitative role of six memory aids in the process of eliminating irrelevant dimensions. The acquisition of the biconditional rule was a linear function of the number of memory aids; but that of the conjunctive rule was not differentially affected by the memory aids. This interaction was attributed to the facilitative role of memory aids in the formation of a relatively complex one, not in the identification of a familiar, easy one. 相似文献

Research Findings: This study examined how child negative emotionality interacted with mothers’ self-reported parenting in predicting different aspects of social functioning among very young Chinese children. A total of 109 Chinese nursery children in Hong Kong participated with their parents. Maternal supportive and aversive parenting practices were reported by mothers, and child negative emotionality and social functioning were reported by both mothers and fathers. The results revealed interaction effects between child negative emotionality and mothers’ self-reported parenting on children’s internalizing problems, externalizing problems, and social-emotional skill deficiency. Specifically, children with high negative emotionality were more susceptible to the negative effects of aversive parenting (i.e., showing more internalizing and externalizing problems when exposed to aversive parenting) than their peers with low negative emotionality. Negative emotionality also placed young children at risk for social-emotional skill deficiency, especially when they received less support from their mothers compared to their peers. Practice or Policy: Special attention should be paid to the social functioning of Chinese children with higher levels of negative emotionality, because these children are more vulnerable to poor-quality parenting at a very young age. 相似文献

This was a study of differential item functioning (DIF) for grades 4, 7, and 10 reading and mathematics items from state criterion-referenced tests. The tests were composed of multiple-choice and constructed-response items. Gender DIF was investigated using POLYSIBTEST and a Rasch procedure. The Rasch procedure flagged more items for DIF than did the simultaneous item bias procedure—particularly multiple-choice items. For both reading and mathematics tests, multiple-choice items generally favored males while constructed-response items generally favored females. Content analyses showed that flagged reading items typically measured text interpretations or implied meanings; males tended to benefit from items that asked them to identify reasonable interpretations and analyses of informational text. Most items that favored females asked students to make their own interpretations and analyses, of both literary and informational text, supported by text-based evidence. Content analysis of mathematics items showed that items favoring males measured geometry, probability, and algebra. Mathematics items favoring females measured statistical interpretations, multistep problem solving, and mathematical reasoning. 相似文献
