This paper focuses on a model of teacher change based on a study of a science discipline-based professional education program and on an understanding of teacher change in terms of an agency| structure dialectic. Professional education programs should expand teachers' capacity to act in a range of fields. Conducted over one year, this study used socio-cultural theory to examine the role of cultural schema and resources in the enactment of new pedagogical structures by two teachers who demonstrated widely variable responses to their experience of a professional chemistry education program. Hermeneutic and phenomenological methods of study supported the examination of teacher actions and narratives as sources of data. The analyses of these data sources resulted in greater understanding of the relationship between schema, resources and structure and the relationship between structure and teacher agency. Structures are dynamic and if a teacher uses a resource such as an inquiry-based instruction protocol without the attendant cultural schema such as the value of questioning then the structure that is implemented will be different from that the teacher experienced in the professional education program. This understanding supported an explanation of teacher change in terms of teacher agency that constituted our learning from the study and resulted in changes to aspects of the professional education program.  相似文献

寂静的深夜,孩子们都已经上床睡了。洗碗机正在刷洗着碗碟;烘干机正烘干第二堆衣物。我终于有了独处的时间,我想真该感谢上帝,难得有这片刻的闲暇。坐在厨房里的桌子旁边,我看见桌上有几张素描草图。7岁的女儿哈莉一直在画素描。我拿起这几张素描仔细看,嗯。有一张素描画的是我丈夫马克和哈莉在一起的样子。由于勾画他们脸部的线条有点弯曲,他们的笑容显得不太自然。“爸爸爱我,”上面写道。另外一张是哈莉和她的哥哥尼古拉斯在一起玩耍的情景。他们正从一片浅绿色的草地跑过,空中棉花糖般的云彩下面一轮昏黄的太阳。“哥哥在跟我玩,”哈莉…  相似文献

In Ireland there is progressive legislation on children’s participation in the education system. The Education Act 1998 advocates that school boards should involve students in the school and establish student councils in second-level schools. Since the publication of this legislation progress on realising students’ participation in schools has been slow. In 2006 the UN Committee on the Rights of the Child recommended that Ireland strengthen its efforts to enable children to express their views in schools and other educational institutions. The National Strategy on Children and Young People’s Participation in Decision-making (2015), the first to be produced internationally, commits to facilitating children and young people’s voice in the development of education policy, the running of schools and in other areas of school policy. This paper presents and discusses the results of qualitative participatory research with children and young people aged between 7 and 17 years, teachers and school principals, and parents, on their attitudes towards and opportunities for participation by students in schools in Ireland. The data reveal that students are keen to participate in school but recognise that their opportunities to do so are inadequate, that teachers understand participation very differently from students, and that parents have little knowledge of their children’s participatory experiences in school. It concludes that effective participation in schools requires policy, practical and cultural change.  相似文献

This study applied expectancy theory to integrate the numerous and disparate explanations that researchers and educators have proposed to account for teacher resistance to implementing cooperative learning as an educational innovation. The cooperative learning implementation questionnaire (CLIQ) contained 48 items grouped under three broad motivational categories: perceived value of the innovation, expectancy of success, and perceived cost. These items accounted for 42.3% of the total variance in self-reported use of cooperative learning among 933 teachers. Expectancy of success issues were most important in differentiating users and non-users, suggesting that increased emphasis on professional development should be used to enhance teachers' beliefs that they can succeed in implementing an innovation in their own context. This may require both follow-up support and adaptation of the innovation.  相似文献

Past practices shape and limit the design imagination of teachers, pupils, parents, governors, and others concerned with designing modern schools. Bringing histories of education to the table in the participatory design process of new school buildings and curricula is necessary. Schools having an extraordinary past have the potential to draw from that prefigurative practice. This paper reports a case study on how the Kees Boeke School in The Netherlands recently has returned to its own history in addressing the needs of its current and future learners in a redesign project. Through addressing the question of how the redesign might reflect a reconnection with the original vision of education espoused by Boeke—learning in relative freedom, with awareness of responsibilities for own and community’s well-being—the school management, architects, teachers, and students took part in a participatory design process. That process and the resulting school design is discussed. From this case study we argue that past adventures in education can inspire current redesign. Past experiences as well as concerns and beliefs about the future are an inevitable influence on initiatives to realise schools for the future, both for schools with experimental and those with traditional histories.  相似文献

Within the context of the growing development of intercultural counsellor education, the question of how different cultures reconceptualize and transform Western counselling theories for their own context is an important one. In this intercultural exchange in education, concepts such as ‘globalization’, ‘indigenization’ and ‘universalization’ have an impact on the education process. This paper briefly explores these terms and movements and then highlights findings from a research project that took place with a group of counselling graduates in Hong Kong examining how they undertook the processes of reconceptualization and transformation. The dialogical process involved in that enabled participants and researcher to co-explore the process of knowledge development within the counselling education field. Implications for counsellor education are highlighted.

This paper examines how scientific and technological (S&T) human capital is transformed into financial capital through the creation of firms by scientists. The analysis is based on a database describing the positions held by 132 founders from 62 French biotech SMEs. It shows that star scientists engage in highly risky but also valuable firms. Less famous scientists must develop their human capital rather than valorising a stock. The paper concludes by pointing to three paradoxes concerning the commitment and compensation scheme of star scientists and the managerial position of less known scientists.  相似文献

Pangolins are among the most critically endangered animals due to heavy poaching and worldwide trafficking. However, their demographic histories and the genomic consequences of their recent population declines remain unknown. We generated high-quality de novo reference genomes for critically endangered Malayan (Manis javanica, MJ) and Chinese (M. pentadactyla, MP) pangolins and re-sequencing population genomic data from 74 MJs and 23 MPs. We recovered the population identities of illegally traded pangolins and previously unrecognized genetic populations that should be protected as evolutionarily distinct conservation units. Demographic reconstruction suggested environmental changes have resulted in a population size fluctuation of pangolins. Additionally, recent population size declines due to human activities have resulted in an increase in inbreeding and genetic load. Deleterious mutations were enriched in genes related to cancer/diseases and cholesterol homeostasis, which may have increased their susceptibility to diseases and decreased their survival potential to adapt to environmental changes and high-cholesterol diets. This comprehensive study provides not only high-quality pangolin reference genomes, but also valuable information concerning the driving factors of long-term population size fluctuations and the genomic impact of recent population size declines due to human activities, which is essential for pangolin conservation management and global action planning.  相似文献

Afforestation in China provides carbon sequestration and prevents soil erosion, but its remote impacts on climate in other regions via the coupling of forest energy fluxes with atmospheric circulation are largely unknown. Here, we prescribe inventory-based forest cover change and satellite-observed leaf area index from 1982 to 2011 in a coupled land-atmosphere model to simulate their biophysical climate effects. Both local and global surface air temperatures show a seasonal contrast in response to past vegetation cover expansion over China: a phenomenon we primarily attribute to a variation of seasonality of vegetation greening. A large cooling in spring results in concurrent decreases in geopotential height over China and zonal wind over Mongolia, causing a dipole structure in the upper troposphere over the Arctic. This accounts for ∼58% of simulated spring warming over the Russian Arctic and ∼61% of simulated spring cooling over the Canadian Artic. Our results imply that spring vegetation dynamics in China may affect climate in northern high latitudes.  相似文献
