The paper discusses the approaches of virtual university strategies and developments in Europe. The discussion is partly based on the work done in the Activity 5 in the EU Thematic Network E4 and partly to the experiences gained through the activities of EUNITE virtual university network of six European universities. Based on our experience we see, that e-learning and virtual university approach can be used for renewal of teaching and learning, both on and off campus. Just three years ago, universities seemed mainly to aim only to develop on campus teaching and learning through ICT. Lately, the use of e-learning as a tool for international cooperation and for virtual mobility (Virtual Erasmus) has started to develop through the activities of the European Union e-learning programmes and through the activities of some European university networks, like EUNITE. To promote virtual universities and e-learning, commitment and actions at all levels from EU to individual institutions are needed.  相似文献

The paper examines the views of students regarding the extent of their participation in the management of their university and their satisfaction with the degree of this participation. After an examination of the literature on student participation in university governance, the author presents the results of a survey based on data collected from 135 students of the University of Cyprus in 2002. According to the findings, respondents believed that their involvement in the management of their institution was very limited. This applied to both high and low levels of decision making, even though respondents recognised that their input was greater in less important decisions. The perceived limited involvement resulted in feelings of frustration and dissatisfaction among students, with the majority of respondents demanding a higher level of participation for all three decision making situations considered in the study. The paper discusses the implications of the findings for the practice of distributed leadership at contemporary universities, with emphasis on the need to abandon outdated leadership models. Specifically, it proposes measures for increasing student participation in university governance in the framework of a distributed leadership approach designed to empower the key stakeholders of higher education.  相似文献

OBJECTIVE: This study compared recidivism rates for alleged maltreatment perpetrators whose initial report was substantiated and those whose initial report was not substantiated, to determine whether they returned to the child welfare system at differing rates. METHOD: Statewide administrative child welfare services data over a period of 4 1/2 years was analyzed. The sample included 31,531 perpetrators of intrafamilial maltreatment. Separate analyses were conducted for each type of maltreatment (sexual abuse, physical abuse, and neglect). RESULTS: Bivariate relationships (substantiation status and recidivism) were analyzed using survival curves, and the study found that recidivism patterns differed by type of maltreatment and by substantiation status at the index event. Multivariate analyses using Cox Proportional Hazards models found that bivariate relationships held true even when controlling for neighborhood mean income, ethnicity, and gender. CONCLUSIONS: The study's finding that perpetrators whose index event was not substantiated return to the child welfare system at a high rate suggests the need to learn how to discriminate those unsubstantiated alleged perpetrators who are most at risk for recidivism. The finding of frequent cross-type recidivism indicates that intervention should focus on common themes across maltreatment types.  相似文献

This study analysis the relationship between perceptions of the justice of teacher’ behaviour and (a) the legitimation of school authority and (b) the legitimation of institutional authorities outside school. 448 adolescent students participated in the study. In questionnaire participants were asked about (a) perceptions of the justice of teachers’ behaviour; (b) evaluation of the school experience; and (c) evaluation of institutional authorities. Results show that the evaluation of the justice of teacher behaviour, in particular relational and procedural justice, have an impact on the legitimation of the authority of teachers and on the evaluation of institutional authorities outside school. Results also show that the legitimacy granted to teachers is a mediator variable between perceptions of justice in school and evaluation of authorities outside school. These results are discussed in the context of the studies on the relationship between school experience and adolescents attitudes towards authorities, and in the framework of the “Relational Model of Authority” and of the “Group Value Model”.  相似文献

Although educational psychologists once were tied in with teachers in solving instructional problems, the progression of the science of psychology has led them away from the practical aspects of teaching. Instead, educational psychologists find themselves talking about theories—in their own language—to each other, and not to their colleagues in the curriculum areas. To this end they are not a continuing source of productive information for solving practical problems in classroom practice. Suggestions are made for improving communication between educational psychologists and on-line educators.  相似文献

The AGIRE project, under the Edulab concept, aims to promote the adoption of innovative teaching practices. This paper reports the support strategies used to evaluate the teacher practices at the end of a teacher training course (TTC) and analyse its impact on teacher technology integration, using a design-based methodology. Teachers’ initial perception was gathered using an online questionnaire comprising ICT personal and professional competencies. The questionnaire results and the classroom observations showed that the majority of teachers were at the level of ICT adoption, before attending the TTC, reaching the adaptation level of integration of ICT, after the TTC. A variety of teaching strategies (flipped classroom, collaborative work, …) and technologies (interactive white boards, tablets, videos, …) were explored. The results sustain the thesis that, with proper support, ICT can be integrated in educational contexts in an innovative way and contribute to the development of teachers’ digital literacy.  相似文献

During the last decades, the education system has been marked by distinct processes of internationalisation. In the field of higher education, there are numerous and varied schools with different international profiles. This paper focuses on processes of internationalisation in the German sector of higher education. We contrast two higher secondary schools with international profiles: one international school in a West German metropolitan region with a long tradition and a younger internationally-profiled school located in the periphery of an East German urban centre. This institutional analysis presents school cultural similarities and differences with regard to different claims and concepts of internationality. This analysis is complemented by a reconstruction of three patterns of biographical meaning examining the internationality of pupils and their respective habitual fit to these internationally-profiled schools. We draw on qualitative data, consisting mainly of interviews with head teachers and pupils of these two schools. We argue that these differing regional forms of internationalisation indicate a stratification and hierarchisation in the field of higher education in Germany.  相似文献

Factors affecting probabilistic judgements in children and adolescents   总被引:1,自引:0,他引:1  
Six hundred and eighteen pupils, enrolled in elementary and junior-high-school classes (Pisa, Italy) were asked to solve a number of probability problems. The main aim of the investigation has been to obtain a better understanding of the origins and nature of some probabilistic intuitive obstacles. A linguistic factor has been identified: It appears that for many children, the concept of certain events is more difficult to comprehend than that of possible events. It has been found that even adolescents have difficulties in detaching the mathematical structure from the practical embodiment of the stochastic situation. In problems where numbers intervene, the magnitude of the numbers considered has an effect on their probability: bigger numbers are more likely to be obtained than smaller ones. Many children seem to be unable to solve probability questions, because of their inability to consider the rational structure of a hazard situation: chance is, by itself, an equalizing factor of probabilities. Positive intuitive capacities have also been identified: some problems referring to compound events are better solved when addressed in a general form than when addressed in a particular way.  相似文献
