ABSTRACTThis paper draws on data collected from two of the most extensive longitudinal studies of care leavers in the US. The Midwest Study (2003–2011) included 732 youths in foster care in three Midwestern states, and the CalYOUTH Study (2012–present) includes 727 youths in California foster care. The paper has three objectives: (1) describe trends in secondary and postsecondary educational attainment at different ages; (2) summarise findings on predictors of educational attainment; and (3) summarise findings on the impact of extended foster care (EFC) on educational attainment. Results from these two studies show that by age 21, 77–85% of care leavers finish a secondary credential and 31–52% enrol in college. By age 25, about 8% have earned a college degree. Results from multivariate analyses find that youths’ educational background and parental status were consistently associated with later educational attainment. Specific aspects of social support also influenced college outcomes. Life demands after enrolling in college (e.g. employment, parenthood) played a more influential role in college degree attainment than did aspects of youths’ background. Characteristics of colleges also predicted youths’ odds of degree completion. Finally, existing evidence suggests that EFC promotes secondary credential completion and college entry, but not college persistence or degree completion. 相似文献

Teachers’ attitudes towards disabled students seem to define the extent to which teaching practices are inclusive. Aiming to explore Cyprus secondary education teachers’ attitudes and practice, and the consequent implications for the future of disabled students and inclusive education, we conducted mixed methods research. Our research typology was sequential and integrated. First, we conducted a survey, during which we received 536 questionnaires from our randomly selected stratified sample of Cyprus secondary education teachers. The survey was followed by interviews with 21 Greek Philology teachers that enriched the findings from the quantitative phase. Data analysis revealed that even though Cyprus secondary education teachers have a rather positive attitude towards disabled students, they have low expectations from them and do not employ inclusive teaching practice. In addition, they tend to categorise students based on abstract notions about ability. Stereotypes and prejudice are more evident regarding students with cognitive disabilities. Despite the observed disabling practices, participants postulated that there is hope to implement inclusive education, if teachers are trained for inclusion and thereby begin to see the person and not the disability. 相似文献

美国校本管理背景下中小学校长的素质能力及其培养培训 总被引:2,自引:0,他引:2
20世纪80年代中期以来,美国大力推行校本管理体制,这使得中小学校长的角色由“行政官员”演变成了学校经营责任人,也使得校长的职能由学校管理转向了学校经营。美国校本管理背景下校长角色地位和职能作用的转变要求校长要具备新的素质能力,对此,相关组织(如州际学校领导者证书联合会)、一些州和学区制定的校长资格标准作了明确的规定。而美国一些研究生院和学区按照校长资格标准的规定,制定并实施了新的校长培养培训计划。 相似文献

The United Arab Emirates (UAE) is making it a requirement of all schools within the Emirates (both public and private) to follow a programme of moral education (MEP), at all ages from grades 1 to 13, which is designed centrally. Explicitly secular and humanist in its approach, this is a remarkable development in a country where Islam is the official religion and where traditional practices and values are deeply rooted. However, it provides an example of an education initiative designed to contribute to a national strategic ambition—that of developing the UAE as a progressive, enlightened country, and one where its residents share a common culture despite the diversity of their origins. This paper describes the programme and sets it in the context of ‘virtue education’, following a philosophical and ethical tradition to which both Arab and Western philosophers have contributed. 相似文献
