The paper presents an analysis of the trends in and links between policies, practices and foreign student enrolment in Italian universities. While the number of foreign students has increased in Italy over the post-war period, the trend and composition of the flow have been affected by changes in government policies and institutional practices regarding foreign students as well as developments in countries sending large numbers of foreign students to Italy. Greek students continue to account for a large proportion of the foreign student population in Italy, but there has been a marked trend toward a reduction in the share of students from developing countries. Over time, foreign student enrolments have become more evenly distributed among faculties and institutions and by gender. Preliminary analyses of degree completion suggest that foreign students progress in their studies at rates slightly lower than Italian students.  相似文献

Preschoolers' Ability to Distinguish Living Kinds as a Function of Regrowth   总被引:6,自引:0,他引:6  
In order to acquire a theory of biology, children must acquire knowledge about living kinds. Although many studies have shown that preschool children do not accurately classify living kinds and do not use appropriate properties when asked to decide whether something is a living kind, recent work has shown that 3- and 4-year-olds do know something about biological growth. The ability of kinds to heal through regrowth was used in this paper as a measure of children's implicit understanding that plants and animals can be grouped together. In 3 experiments, children were told that animals, plants, and artifacts had been damaged and were asked whether the objects could heal through regorwth and whether a person could mend them. In all studies, children were sensitive to ontological kind, 4-year-olds realized that both plants and animals can regrow but that artifacts must be fixed by human intervention. 3-year-olds were less knowledgeable but did realize that artifacts cannot regrow. Overall, children showed some biological knowledge, implicity grouping plants and animals together and differentiating them from artifacts.  相似文献

The aim of the current study is to better understand the decision-making of men considering teaching as a career option. By means of a longitudinal study (n = 226), we examined the persistence of male academic high-school students in Switzerland interested in teaching during transition to higher education. For 85 men attending information events for teacher education, using regression analysis we explore factors contributing to their decidedness and volition before enrolling for teacher education studies. The findings reveal that only a very small number of male academic high-school students are interested in teaching. Those who are, however, are persistent in their study choice. Results of the regression analysis show that an interest in working with children and youth, the importance of having free time for other things and having professional experience working with children contribute to the likelihood of men having decided to take up teacher education studies.  相似文献

The unique relation of language use (i.e., output) to language growth was investigated for forty‐seven 30‐month‐old Spanish–English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive language skills were assessed at 30, 36, and 42 months. Longitudinal multilevel modeling indicated an effect of output on expressive vocabulary growth only. The finding that output specifically benefits the development of expressive language skill has implications for understanding effects of language use on language skill in monolingual and bilingual development, and potentially, for understanding consequences of cultural differences in how much children are expected to talk in conversation with adults.  相似文献

This article reviews current scholarship about how to promote change in instructional practices used in undergraduate science, technology, engineering, and mathematics (STEM) courses. The review is based on 191 conceptual and empirical journal articles published between 1995 and 2008. Four broad categories of change strategies were developed to capture core differences within this body of literature: disseminating curriculum and pedagogy, developing reflective teachers, enacting policy, and developing shared vision. STEM education researchers largely write about change in terms of disseminating curriculum and pedagogy. Faculty development researchers largely write about change in terms of developing reflective teachers. Higher education researchers largely write about change in terms of enacting policy. New work often does not build on prior empirical or theoretical work. Although most articles claim success of the change strategy studied, evidence presented to support these claims is typically not strong. For example, only 21% of articles that studied implementation of a change strategy were categorized as presenting strong evidence to support claims of success or failure of the strategy. These analyses suggest that the state of change strategies and the study of change strategies are weak, and that research communities that study and enact change are largely isolated from one‐another. In spite of the weak state of the literature, some conclusions related to the design of change strategies can be drawn from this review. Two commonly used change strategies are clearly not effective: developing and testing “best practice” curricular materials and then making these materials available to other faculty and “top‐down” policy‐making meant to influence instructional practices. Effective change strategies: are aligned with or seek to change the beliefs of the individuals involved; involve long‐term interventions, lasting at least one semester; require understanding a college or university as a complex system and designing a strategy that is compatible with this system. © 2011 Wiley Periodicals, Inc.

Interdepartmental integration, the melding together of disparate functional areas within an organization, is believed to be associated with superior firm performance. However, the particular approach that human resource development practitioners should focus on to improve performance is not well‐understood. Our research assesses three alternative approaches to interdepartmental integration: the interaction, collaboration, and combination views. The interaction view suggests that successful interdepartmental integration is achieved primarily by increasing the volume of meetings and documented information exchange; the collaboration view prescribes teamwork, sharing, and the achievement of collective goals. The third view suggests that Successful integration involves a combination of interaction and collaboration. The results of a recent survey of functional managers are presented. The findings indicate that interaction and collaboration are both positively associated with performance and extendi previous empirical work by suggesting that, when viewed collectively, collaboration mediates the relationship between interaction and performance. Implications for practice and future research are discussed.  相似文献

Much academic analysis of media representations of drugs-related violence in Brazil has focused on their role in perpetuating violence and societal divisions. There is less research on how the country’s traditional news media can shape information in order to foster dialogue between people and potentially resolve conflict. This article aims to address this gap by exploring the possibilities and challenges for printed news media to acquire “mediated” social capital. The concept is understood here as a specific resource of power that has the potential to connect people from diverse social, cultural and economic backgrounds. In order to do so, we analyse how a popular Rio newspaper has used its symbolic power to produce social capital with an investigative series about Brazil’s involvement in the international drugs trade. It is argued here that the series paints a complex picture of its causes and consequences and is an important step towards a deliberative process about possible solutions to drugs-related violence in Rio and beyond.  相似文献

Four hundred and eighty-four students from two metropolitan secondary schools completed the Learning Process Questionnaire, the Individualised Classroom Environment Questionnaire and the Learner Self Concept scale. Relationships between perceptions of the classroom learning environment, approaches to learning and self concept as a learner were investigated. Gender and level of schooling (junior high versus senior high) differences were examined. Results showed Deep Approaches to learning were significantly related to classroom learning environments which were perceived to be highly personalised and to be encouraging active participation in the learning process and the use of investigative skills in learning activities. High learner self concept was positively associated with Deep Approaches to learning and with classrooms perceived as high in Personalisation. It was negatively associated with Surface Approaches to learning. Differences in perceptions of learning environments and approaches to learning in relation to gender and level of schooling were small. The implications of these findings are discussed and strategies for facilitating Deep Approaches to learning are referred to. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

We examined the extent to which nonhedonically different differential outcomes involving feeder location control pigeons’ comparison choices in matching to sample. In Experiment 1, we showed that differential feeder location outcomes associated with each of two samples can facilitate delayed-matching accuracy. In Experiment 2, we found positive transfer following training on two matching tasks with differential feeder location outcomes when samples from one task were replaced by samples from the other task. In Experiment 3, we found that when differential-outcome expectations could no longer serve as the cues for comparison choice, sample stimuli continued to exert some control over choice of comparisons. The results indicate that differential outcomes (involving feeder location) that presumably do not differ in hedonic value are sufficient to control comparison choice. Thus, the differential hedonic value of the outcome elicited by the sample does not appear to be a requirement of the differential-outcome effect. Furthermore, these differential outcomes appear to augment matching accuracy, but they do not eliminate control by the samples.  相似文献
