Higher education has adopted an innovation imperative that has driven significant transformations in the sector. A new kind of learning programme, based on problem‐solving, design thinking, creativity and “pluridisciplinarity” has emerged in the last two decades and become an emblematic form of learning to cope with current “complex” economic and societal problems by examining their roots at ground level. The French case study allows one to understand the distance between general policy orientations for innovation and actors' capacity and the need to take into account the local context.  相似文献

The aim of this study was to examine the relation of parental supervision, parental involvement at school and child's social competence with school achievement in primary school. A theoretical model was postulated that predicts direct and indirect effects of parental behaviors on adolescents’ school achievement. Participants were 1,024 adolescents attending Grades 5 through 8 in 20 primary schools in Croatia and one of their parents or guardians. Adolescents completed a scale assessing their self‐perceived social competence and data on their grade point average were collected. Parents completed scales measuring parental supervision and parental involvement at school and they rated their child's social competence. The results of model testing showed that parental behaviors have both direct and indirect effect on adolescents’ school achievement. Greater parental supervision and school involvement have a direct and an indirect, through their effects on child's social competence, positive effects on adolescents’ school achievement.  相似文献

Despite clear European and Dutch policies about media education, there is currently no media education curriculum in Dutch schools. A survey among preadolescents (n = 257) in six primary schools in the Netherlands included questions regarding media access, fears, risks, parental mediation of television and the internet, and the need for media education. Findings indicate an overall high saturation of media, but media choice depends on sociodemographic factors. Preadolescents are given rules for using the internet more often than for TV. Boys feel more confident about media use, and few participants report negative experiences or perceive risks while using the internet. Pupils feel a high need for media education, and those who are already thinking critically about media demand lessons more often. Therefore, both technical knowledge about media and critical awareness of the influence of media must be taught.  相似文献

A survey was developed to benchmark the affective sustainability characteristics of an incoming cohort of students in a Polytechnic in New Zealand, with the intention to monitor changes in these attributes as the students experience higher education over subsequent years. The survey contained a number of research instruments as we were interested in exploring how best to record these attributes. This article reports on the comparative efficacy of four of these instruments in describing the affective characteristics of the students. All the instruments depended on respondents’ self‐reporting in the absence of researchers or interviewers. The results do encourage us to have some confidence that students’ sustainability characteristics may be researched using a variety of survey‐based research instruments, and particular confidence in ongoing use of the Revised New Ecological Paradigm (NEP) scale.  相似文献

Data from 2 studies revealed that ethnic and sexual minority clients experienced greater psychological distress on multiple dimensions than did European American or heterosexual clients, respectively, as did ethnic and sexual minority students who were not clients. Among sexual minority students, ethnicity was not an added source of distress. Among ethnic minority students, sexual minority status was associated with heightened psychological distress.  相似文献

This article is part of a series in this regular feature, which looks at new directions in health science libraries. It highlights the initiatives health science librarians in Tanzania are implementing to ensure that their service meets users’ needs. To succeed, libraries must take steps to ensure that staff have access to education, training and professional development. Partnerships and collaborations are also vital to make the best use of scarce resources and to identify sources of funding. This article highlights the various challenges facing the library service and the opportunity for librarians to be recognised for the new roles they are taking on. J.M.  相似文献

The Chinese Medical Association, one of the largest and most influential medical journal publishers in China, signed an exclusive copyright transfer agreement with Beijing Wanfang Data Co. Ltd in 2006, which ended the era of cheap transfer of copyrights from journals to full‐text databases. Since then, many journals have chosen the same route to earn more money. However, without generally recognized databases that offer free access to medical abstracts in China, many potential readers are lost. In addition, many Chinese readers do not have adequate literature retrieval skills: more convenient access to journals is therefore far more important than earning immediate profits. Goods in exclusive shops are more expensive than those in ordinary shops. That is why many journals sell exclusive copyrights to databases. However, while obtaining more profits by exclusive copyright transfer, journals may actually lose a large proportion of readers.  相似文献
