AbstractLarge numbers of children of low income families in the United States arrive at kindergarten already far behind their more affluent peers on measures of school readiness. In the absence of any federal preschool policy and amidst alarm about this growing divide, universal prekindergarten (UPK) programs have been launched around the United States, at both the state and local levels, to address the school readiness gap. Invest in Children, a public/private partnership in Cuyahoga County (Cleveland, OH) launched a UPK program of high quality, affordable preschool nine years ago. The program’s creation, implementation and challenges are discussed along with evaluation findings that document its positive impact on school readiness. Lessons learned are discussed in terms of the impact of political and economic shifts, as well as state policy changes, on this local program. The program’s planned expansion and enhancements to program design and evaluation are also described. 相似文献

Why buy commercial toys when they can be easily made? As you know, very young children will often bypass expensive toys and play with spoons, lids, or even boxes and cans. You can have fun making toys for babies and toddlers from readily obtained materials. 相似文献

OBJECTIVE: The present study evaluated the association between women's health and physical and sexual abuse suffered before age 18. METHODS: A total of 3,568 randomly sampled insured women ages 18-64 completed a telephone interview to assess history of physical only, sexual only, or both physical and sexual abuse before age 18 (Behavioral Risk Factor Surveillance System); and current health (Short Form-36, Center for Epidemiologic Studies-Depression, Presence of Symptoms surveys). Adjusted analyses compared the health of women with physical abuse only, sexual abuse only, or physical and sexual abuse to the health of women without these abuse histories. RESULTS: Poorest health status was observed in women with a history of both physical and sexual child abuse compared to women without these abuse histories. In models that adjusted for age and income, women with both abuse types had increased prevalence of depression (prevalence ratio, 2.16), severe depression (PR, 2.84), physical symptoms (PR range, 1.33 for joint pain to 2.78 for nausea/vomiting), fair/poor health (PR, 1.84), and lower SF-36 scores (3.15-5.40 points lower). Women with physical abuse only or sexual abuse only also had higher prevalence of symptoms and lower SF-36 scores but the associations were not as strong. CONCLUSIONS: This study adds to the literature showing a graded association between multiple adverse events in childhood and adult health. 相似文献

Executive functions (EF) have been studied extensively in children and adults. However, EF tasks for young children can be difficult to administer and interpret. Espy (1997, Developmental Neuropsychology, 13, 495–499) designed the Shape School task to measure inhibition and switching in preschool-aged children. Shape School presents cartoon-like characters that children must flexibly name by their color, their shape, or both, depending on cues that indicate the appropriate rule. Shape School has been found to be age sensitive as well as predictive of performance on other EF tasks. We presented a computerized analogue of Shape School to seven rhesus macaques. Monkeys were trained to categorize characters by color or shape, or to inhibit this response, depending on whether the characters had eyes open, eyes closed, or wore hats. Monkeys performed above chance on the inhibition and switching components of the task. Long runs of a single classification rule and long runs of noninhibition trials had no significant impact on performance when the rule changed or inhibition was required. This nonverbal adaptation of Shape School can measure EF in nonhuman animals and could be used in conjunction with other EF tasks to provide a clearer picture of both human and nonhuman executive functions. 相似文献

This paper reports the findings of a project—‘Lifelong learning and teacher education’—undertaken by the Centre for Lifelong Learning, Australian Catholic University, under the auspices of the Australian Commonwealth Department of Education, Science and Training. The study was designed to investigate the operationalization of lifelong learning in Australian teacher education. The study revealed that there is a range of existing, innovative practices regarding partnerships between schools and higher and further education that are in keeping with emerging ideas about lifelong learning. Moreover, some of these take the form of collaborative action research projects focused on improving the learning occurring in the partnership schools. This paper describes some current approaches in Australia to collaborative action research by teacher educators' and their partnership schools and shows how they contribute to lifelong learning. The approaches are then analyzed to suggest ways of advancing lifelong learning within Australian Education Faculties thus helping to make lifelong learning more of a reality for all. 相似文献
