Forty‐eight toddlers aged 17 to 31 months attending long‐day childcare participated in this project, which examined some of the influences of the day‐care context on their emerging pretend play. Ninety minutes of video‐taped observations were collected for each participant as they engaged in free play with their same‐age peers and their pre‐school‐aged peers. The play environment was assessed on a number of dimensions, including the provision of play materials, the quality of care and staff attitudes toward play. Additionally, the participants' weekly attendance pattern was taken into consideration. The complexity of pretend play was coded in accordance with Westby's Symbolic Play Scale (1991 Westby C A scale for assessing children's pretend play 1991 in: C. E. Shaefer, K. Gitlin & A. Sandgrund (Eds) Play diagnosis and assessment New York Wiley 131 161  [Google Scholar]). Two components of the long‐day childcare context—play with pre‐school‐aged peers and the unsatisfactory provision of play materials—were found to be significantly influential on the participants' complexity of pretend play. An attendance of four or more days in childcare was also found to be favourable. A number of implications for educational programming in the day‐care context arise from these results.  相似文献

OBJECTIVES: The study examined child, parent, and case characteristics in a sample of 200 cases of serious child maltreatment brought before the Boston Juvenile Court (BJC) on Care and Protection petitions in 1994. Whether recent changes in Massachusetts law have been effective in reducing delays in adjudication and helping children achieve permanent placements more quickly was also examined. METHOD: Data were abstracted from court records by the research team. The 200 cases were followed prospectively for 4 years. Retrospective data on the families' previous involvement with the protective service system were also abstracted from the records. Data from the 1994 cases were compared to that obtained from a sample of cases brought before the BJC in 1985-1986. RESULTS: Children permanently removed from parental custody in the 1994 sample required less time post-disposition to achieve permanent placements. However, overall, time frames for the 1994 cases remained remarkably similar to those in 1985-1986: children were in the protective service system an average of 5 years; cases required an average of 1.6 years in court; and half of the children permanently removed from parental custody were still in "temporary" foster care at 4-year follow-up. CONCLUSIONS: Although some improvements have occurred since 1985-1986, the system still fails to meet the needs of seriously maltreated children to achieve permanent placements promptly. The implications of the findings for system reform are discussed.  相似文献

The paper is based on research into the position of women academic staff in a sample of colleges of higher education in England. This reveals a pattern of entrenched sexual inequality in these institutions, especially at middle and senior management levels. A similar pattern has been found in the university and polytechnic sectors of higher education. However, in the colleges there is an even greater disjunction between the sexual distribution of students and staff. The research is related to recent literature on equal opportunities in education. It is argued that the formal curriculum of equal opportunities is continually subverted by a hidden curriculum of unequal opportunities. Finally, several approaches to positive intervention are suggested.  相似文献

Previous experiments have shown that the intake of a 0.15% saccharin solution is suppressed if saccharin access is followed by access to 32 % sucrose in brief daily pairings. The present experiments found that: (1) the degree of suppression was not altered when no time elapsed between presentation of the two solutions each day (15 sec had been the minimum in previous experiments and was used as the control in this experiment); (2) the degree of suppression was not altered by chlordiazepoxide (6, 12, or 20 mg/kg), although the drug had large appetite-stimulating effects; (3) suppression was not influenced by amphetamine (0.25 or 0.50 mg/kg); and (4) contrast could be established or eliminated, even after extended training, by manipulating the sequences of solutions presented (saccharin-saccharin or saccharin-sucrose). The results were interpreted in terms of a contrast effect based on the learned anticipation of a preferred substance. The chlordiazepoxide data suggest that this contrast is different from successive negative contrast, and the intersolution interval data suggest that the occurrence of contrast rather than a reinforcement effect is not due to a time gap between presentations of the two solutions.  相似文献

The authors review research literature on coherent theoretically based approaches to the use of reflective processes within programmes of initial professional education for new academic staff. Employing a novel methodology that incorporates practitioner perspectives, they establish a framework that highlights the role of personal and social factors, and also pedagogic and theoretical considerations, in shaping reflective processes. The included studies identified participants who had engaged in certain categories of reflection. Certain fundamental outcomes, however, such as changes in professional commitment, were never seen across an entire cohort. The article thus discusses the intended learning outcomes that programmes might legitimately seek to meet.

Dans cet article, nous examinons la littérature de recherche portant sur les approches théoriques cohérentes sur l’usage des processus réflexifs dans le cadre de programmes d’éducation professionnelle initiale pour le personnel académique novice. A l’aide d’une nouvelle méthodologie incorporant les perspectives du praticien, nous établissons un cadre qui met en lumière le rôle des facteurs sociaux et personnels, de même que les considérations théoriques et pédagogiques, mettant en forme les processus réflexifs. Les études visées par l’article ont permis d’identifier des participants s’étant engagés dans certaines catégories de réflexion. Des conséquences fondamentales, telles que le changement au niveau de l’engagement professionnel, n’ont cependant pas été observés pour l’ensemble de la cohorte. Nous discutons donc des objectifs d’apprentissage que les programmes pourraient, de façon légitime, chercher à atteindre.  相似文献

2009年9月,日本东近江市面向乘坐本市公交快线的居民,开展了收集废弃食用油的活动。收集上来的食用油通过提炼,最终变成生物柴油,为运营在该市1 2条线路上的快速公交车提供燃料。由于发起"油菜花"环保项目,东近江市已受到日本全国的关注。该项目涉及一系列旨在为东近江市创建基于资源循环利用的基础设施的倡议,其中包含油菜的种植、菜子油的日常食用、废弃食用油的回收和提炼成燃  相似文献
