It would seem a foregone conclusion that early childhood program directors need a knowledge base in child development if they are to establish credibility in their role as directors (Kuykendall, 1990). The general assumption, then, is that directors' client base is young children. However, early childhood program directors in their daily experiences deal with opposite ends of the development continuum from children to adults.Sharon L.

This paper addresses the question of the extent to which there were improvements in equity in the patterns of participation of young people in higher education in Australia during the 1980s. Data from theYouth in Transition longitudinal surveys of Australian youth are used to assess the effectiveness of the Labor Government's equity initiatives since 1983 in this area. The conclusion is that participation by young people in higher education in Australia did generally become more equitable under Labor during the 1980s, though differences in higher education participation rates persisted between certain sub-groups of the population.  相似文献

In order to determine how well medical examiners agree on the significance of certain anogenital findings in children, preselected colposcopic photographs of the anogenital area of 16 patients were shown to 170 medical examiners (82% pediatricians) who were blinded as to the history on each patient. Findings rated most frequently as being suggestive or indicative of penetrating injury included immediate anal dilatation with no stool present (85%), hymenal transection (84%), marked narrowing of the hymenal rim with notching (81%), and a posterior fourchette scar (75%). The agreement between the participants and the experts on the abnormal cases (mean 81%) was significantly higher than on the normal cases (mean 71%, p < .001) and on genital findings (78%) than on anal findings (63%, p = .000). Higher experience level (more cases seen per month) was associated with significantly higher agreement between the participants and the experts on five of eight normal cases and two of four abnormal cases. Use of a colposcope was also associated with higher overall agreement with the experts (74% vs. 44%, p < .0001).  相似文献

The six national goals established by the National Governors' Association for education reform in the 1990s were conceived by people who had the power to decide what outcomes they wanted based on their own values and priorities. Although it is impossible to avoid questions of values, it is necessary in defining goals for education to consider scientific, explanatory theories about how human beings acquire knowledge and moral values. Jean Piaget's conceptualization of autonomy, in his unusual sense of the term, provides an overall aim for the development of individuals as well as of society, both in the intellectual and the moral realms. Autonomy as the aim of education is based on constructivism, a scientific theory, and would obviate the outdated conceptualization and contradictions among the six national goals.  相似文献

Through this study the authors evaluate outcomes associated with the use of handheld computers by interventionists in improving the efficiency of direct systematic classroom observation. Information from observations is used by interventionists for treatment planning and evaluation. In this study, interventionists were trained to use personal digital assistants with classroom observational software for use with students who displayed low levels of academic engagement. Results indicated that the personal digital assistants and observational software were perceived as user-friendly, increased computer self-efficacy, and facilitated treatment planning and evaluation. Discussion focuses on implications for use of handheld computers and mobile devices by interventionists.  相似文献

This article presents a review of research studies examining instructional methods reported in the social work education literature published between 1998 and 2008. From a sample of 91 studies, 31 were identified as having used either a single group pre/post test design or a comparison of two or more groups and inclusion of a learning outcome measure. Most of the studies were deficient in either the employment of comparison groups, pre/post designs, utilization of multiple learning outcome measures, or a clear delineation of the connection between teaching methods and learning outcomes. Very few studies were based on previous work. A challenge is made to the field to conduct better designed studies and several suggestions for doing so are offered.  相似文献

Critical thought is a necessary element for proficient practice in social work at both the micro and macro levels. For this reason, social work educators must seek to integrate critical thought in BSW and MSW curricula. This article provides a method for achieving this integration in the social welfare policy course. The method includes the four following phases: instruction regarding logical errors, presentation of logical errors in contemporary political debate, demonstration of critical thought in policy position analysis, and self-assessment of one's own logic. The implications of this method for practice in a values-based context are discussed.  相似文献

In the current context, the need for marketing in institutions of higher education is undeniable. The specification of the student not merely as a ‘customer’ means that traditional marketing no longer has sufficient capacity to explain the behavior of the student body. In this study, a four-level relationship marketing model is tested to check the influence of perceived organizational support (POS) and perceived employability on identification with the institution and the perceived price-quality ratio and how these influence student satisfaction. In addition, the constructs prior to POS and perceived employability are identified, which are explicit enough to enable specific marketing actions to be carried out. As POS is a construct defined for the labor market, its use applied to relational marketing comes up as something innovative.

To this end, Likert scales have been designed and validated to measure these constructs. The results of this test show how the perception of organizational support depends on the relationship of the student body with the administration and management of the center. Likewise, the perception of employability depends on the perceived reputation and the perception of the promotion of employability. Furthermore, it is confirmed that satisfaction is positively related to identification and the perceived price-quality ratio, which in turn are positively related to organizational support and perceived employability.  相似文献

This study examines cross‐cultural interpretations of icons and images drawn from US academic websites. Participants from Morocco, Sri Lanka, Turkey, and the USA responded to an online questionnaire containing 18 icons and images representing online functions and information types common on US academic websites. Participants supplied meanings for icons and images and selected a preferred image to represent each of four specific online functions. From three images of professors, participants chose one with whom they would prefer to study. Data were collected at the University of New Mexico, USA; in Internet cafes in the Middle Atlas region and at Al‐Akhawayn University, Morocco; the Open University of Sri Lanka in Nawala, Nugegoda; and at Anadolu University, Turkey. A qualitative analysis examines participants' perspectives and preferences for specific representations and identifies cultural themes in relation to Hofstede's dimensions. Implications for the design of images for cross‐cultural users are discussed.

L'interprétation culturelle de la signification visuelle des icônes et images utilisées dans la conception de sites Web en Amérique du Nord

La présente étude porte sur les interprétations transculturelles des icônes et des images extraites de sites universitaires américains. Des participants venus du Maroc,du Sri Lanka, de Turquie et des Etats Unis, ont répondu à un questionnaire en ligne contenant 18 icônes et images représentant des fonctions en ligne et des modes d'information que l'on trouve couramment sur les sites universitaires américains. Ces participants ont attribué des significations aux icônes et images et sélectionné l'image qu'ils (elles) préféraient pour représenter chacune des quatre fonctions en ligne proposées. A partir de trois images de professeurs,les participants en ont choisi une, celle avec qui ils (elles) préféreraient étudier. Une étude quantitative examine les perspectives des participants et leurs préférences pour une représentation donnée et elle identifie les thèmes culturels par rapport aux dimensions de Hofstede. On étudie les conséquences que cela peut avoir pour la conception d'images destinées à des utilisateurs interculturels.

Kulturelle Interpretationen der visuellen Bedeutung der Symbole und Bilder, die in Nordamerika Web‐Design benutzt werden

Diese Studie untersucht cross‐kulturelle Interpretationen von Symbolen und Bildern, die in akademischen US‐Websites benutzt werden. Teilnehmer aus Marokko, Sri Lanka, der Türkei und den USA bearbeiteten einen Online‐Fragebogen mit 18 Ikonen und Bildern, die Online‐Funktionen und – Informationen auf akademischen US‐Websites gemeinsamen sind. Die Teilnehmer benannten angenommene Bedeutungen der Symbole und Bilder und wählten ein bevorzugtes Bild für jede der vier spezifischen Online‐Funktionen aus. Aus drei Bildern von Professoren wählten die Teilnehmer eines aus, das denjenigen zeigen sollte, mit dem sie es vorziehen würden zu studieren. Eine qualitative Analyse untersucht Perspektiven und Präferenzen der Teilnehmer für bestimmte Vertretungen und Identitäten kultureller Themen in Bezug auf die von Hofstede aufgestellten Dimensionen. Auswirkungen auf die Gestaltung von Bildern für cross‐kulturelle Nutzer werden diskutiert.

La interpretación cultural del significado visual de iconos y imagenes utilizados en el diseño de sitios Web en América del Norte

Este artículo examina las interpretaciones transculturales de iconos y imágenes procedentes de sitios académicos de los Estados Unidos. Participantes de Marruecos, Sri Lanka, Turquía y los EUA respondierón a un cuestionario en línea conteniendo 18 iconos y imágenes que representan funciones en línea y tipos de información que se encuentran frecuentemente en los sitios académicos de los EUA. Los participantes propusieron significados para los iconos y imágenes y seleccionarón la imágen que les parecía más idónea para representar cada una de cuatros funciones en línea específicas. Entre tres imágenes de profesores, los participantes seleccionarón una, la de la persona con quien les gustaría estudiar. Un análisis cualitativo examina las perspectivas y preferencias de los participantes para tal o tal representación específica y al mismo tiempo se analiza temas culturales en relación con las dimensiones de Hofstede. Se analizan también las consecuencias que esto conlleva para el diseño de imágenes destinadas a usuarios transculturales.  相似文献

In the current climate of accountability, action research is one way for teachers to evaluate instructional changes designed to improve assessment results. It may become increasingly common for administrators to mandate teacher involvement in action research, yet few studies have been conducted in such settings. This article focuses on one middle school where the principal mandated action research for all teachers. Projects were carried out within academic departments, and department chairs were given latitude in how to organize and implement projects. This study explores project implementation and teacher perceptions of the action research. Interviews were used as an appropriate tool to explore teacher perceptions, with document analysis providing triangulation. Results from interviews of administrators, department chairs, and department members suggest an overall positive attitude toward action research, as well as variation in how action research projects were carried out. Differences occurred across several dimensions of action research, including context, motivation/ purpose, definition of action research, and organization of projects. Variations appeared to be influenced by each department chair’s experience with action research and approach to departmental work, and each department’s history of working together on instructional improvement efforts. This study suggests that administrators who mandate teacher participation in action research projects need to think about both the positive (providing teacher ownership and interest within the mandated context) and problematic (possibly leading to variation in the instructional impact of projects) aspects of project variation.  相似文献
