The Edmund Rice Education Australia (EREA) Flexible Learning Centres aim to provide a supportive learning environment for young people who find themselves outside of the mainstream secondary schooling system. Drawing on twenty first Century learning principles, the Centres aim to deliver a personalised learning experience with an emphasis on flexibility and individual choice. Provision of a comprehensive curriculum enables young people to make positive future life choices and successfully transition into employment and further training. The aim of this research project has been to work with teaching staff at a Flexible Learning Centre in North Queensland, Australia, to explore the value of integrating ICT in the form of Web 2.0 technologies to enhance young people??s engagement with the subject of science. The findings of this case study suggest that ICT integration is effective in revitalising science education interest for disengaged young people. This may have wider implications in relation to general concerns of declining student interest and participation in science in the secondary years of schooling.  相似文献

During the past decade, parents and educators have increasingly expressed concern over the potential safety and developmental risks associated with children in self-care, or the care of another child (Garbarino, 1984; Harris, Kagay, & Ross, 1987; Robinson, Rowland, & Coleman, 1986; 1989; Zigler & Ennis, 1988). One result has been a growing interest in school-age child care (SACC) programs.Mick Coleman is Assistant Professor, Child and Family Development, and Extension Human Development Specialist, University of Georgia, Hoke Smith Annex, Athens, Ga.

Control of pigeons’ keypecking by a stimulus-reinforcer contingency was investigated in the context of a four-component multiple schedule. In each of three experiments, pigeons were exposed to a schedule consisting of two two-component sequences. Discriminative stimuli identifying each sequence were present only in Component 1, which was 4, 6, or 8 sec in duration, while reinforcers could be earned only in Component 2 (30 sec in duration). Control by a stimulus-reinforcer contingency was sought during Component 1 by arranging a differential relation between Component 1 cues and schedule of reinforcement in Component 2. In Experiment 1, rate of keypecking during Component 1 varied with the presence and absence of a stimulus-reinforcer contingency. When a contingency was introduced, rate of keypecking increased during the Component 1 cue associated with the availability of reinforcement in Component 2. In Experiment 2, the stimulus-reinforcer contingency was manipulated parametrically by varying the correlation between Component 1 cues and Component 2 schedules of reinforcement. Responding in Component 1 varied as a function of strength of the stimulus-reinforcer contingency. The relatively high rates of Component 1 responding observed in Experiments 1 and 2 pose difficulties for conceptions of stimulus-reinforcer control based on probability of reinforcement. In these two experiments, the stimulus-associated probabilities of reinforcement in Component 1 were invariant at zero. An alternate dimension of stimulus-reinforcer control was explored in Experiment 3, in which Component 1 cues were differentially associated with delay to reinforcement in Component 2, while probability of reinforcement was held constant across components. When the stimulus-reinforcer contingency was in force, rate of responding in Component 1 varied inversely with delay to reinforcement in Component 2. In a quantitative analysis of data from Experiments 2 and 3, relative rate of responding during Component 1 was strongly correlated with two measures of relative delay to reinforcement.  相似文献

Ratings awarded to university departments in the UK Research Assessment Exercise (RAE) 2001 were analysed to determine whether they were influenced either by the status of the university (pre‐1992 or post‐1992) or by whether the university was represented on the panel that determined the ratings. There was little evidence that panel membership has any effect on ratings, but an analysis of covariance also showed that, among universities not on the panel, pre‐1992 universities were more favourably assessed, relative to post‐1992 universities, than would be expected on the basis of their ratings in the 1996 RAE. This finding, along with the preponderance of pre‐1992 universities on all panels (even those where the majority of the research is conducted by post‐1992 universities), is used to urge strongly that in future RAEs, panel membership should be made much more representative of higher education in general and of the institutions submitting the research considered by each panel in particular.  相似文献

The paper suggests that there is currently a good deal of uncertainty over the role of the principal, which is frequently described as one of educational leadership. This notion seems obsolete. Currently, there are pressures on principals to substantially modify this role, and these pressures seem to push the principal toward the definition of his role as that of administrator. On the basis of the beliefs of those involved in training programs for educational administrators, it is possible to predict that the future role of the school principal will, in fact, be that of building or school administrator. The role can be defined as that of administrative leader, as opposed to instructional leader. Administrative leadership involves at least the following elements: purpose-definding for the organization; coordination of the work of specialists, including decision-making; and responsibility for external relationships. The paper concludes by pointing out that this redefinition of the role of the school administrator, or administrative leader, has significant implications for in-service training for administrators, collective negotiations, and affiliation with teacher associations.
Résumé D'après cet article, il y aurait actuellement une bonne dose d'incertitude quant au rôle du principal, rôle assimilé fréquemment à celui d'un leader en éducation. Or cette notion semble être périmée. De nos jours, les principaux d'écoles sont soumis à des pressions pour modifier considérablement ce rôle et ces pressions semblent pousser le principal à considérer son rôle comme celui d'un administrateur. D'après les croyances entretenues par les responsables des programmes de formation des administrateurs scolaires, il est possible de prédire que le rôle futur du principal d'école sera, en fait, comparable à celui d'un administrateur d'école ou d'immeuble. Ce rôle peut être assimilé au rôle de directeur administratif qui se distingue du directeur pédagogique. La direction administrative implique, au minimum, les éléments suivants: définition des objectifs d'organisation, coordination du travail des spécialistes, y compris la formulation de la politique et enfin responsabilité des relations externes. En conclusion, l'auteur souligne que cette redéfinition du rôle de l'administrateur scolaire ou du directeur administratif a des répercussions considérables sur la formation pratique des administrateurs, les négociations collectives et l'adhésion aux associations d'enseignants.

Since 1994, 14 reliable national studies have provided longitudinal data revealing and analyzing trends in the public access computing, Internet access, and technology assistance and training that public libraries make available to the communities they serve. This article provides an overview of selected data from the 2012 study; examines major issues that have emerged from the data in the most recent studies; identifies key trends and changes in Internet-enabled services and resources provided by public libraries to their communities over the course of the 18 years of conducting the national surveys; and discusses selected future issues and challenges regarding public library Internet-enabled services.  相似文献

ABSTRACT

A national survey of academic librarians was conducted to examine relationships among reference service staffing changes, reference service innovations, adoption of reference technology, library type and size, and service quality. Analysis of the 606 response sets reveals trends toward reduced use of librarians and increased use of student staff at in-person service points, widespread increases in appointment-based and self-service reference, intensive efforts to reduce demand for reference by improving library instruction, and general improvements in reference service quality. Factors strongly associated with decreases or increases in quality are discussed in detail and implications for reference managers are provided.  相似文献
