ResumenSegún el modelo de la diferenciación se puede predecir que ambientes familiares que permiten al niño la organización y estructuración de sus propias experiencias deben favorecer el desarrollo de un estilo cognitivo más independiente de campo. Con el fin de poner a prueba dicha predicción, en este trabajo se estudia la posible asociación entre el estilo cognitivo dependencia-independencia de campo (DIC) y los tipos de estructuración del medio ambiente familiar (EMAF) propuestos por Lautrey. Para ello se aplicó el Embedded Figures Test (EFT) a 91 niños de 12 a 14 años procedentes de familias con distinta estructuración normativa. Los análisis realizados muestran diferencias significativas en el estilo cognitivo de los niños según el tipo de EMAF: los niños de familias flexibles y débiles son más independientes de campo que los niños de familias rígidas. Los resultados confirman parcialmente las previsiones recalzadas desde el modelo de la diferenciación. 相似文献

We explore the experiences of school science teachers as they enact three linked national curriculum and assessment policy reforms in Sweden. Our goal is to understand teachers’ differing responses to these reforms. A sample of 13 teachers engaged in 2 interviews over a 6–9-month period. Interviews included exploration of professional background and school context, perceptions of the aims of the policy reforms and experiences of working with these reforms in the classroom. Analysis was guided by an individual-oriented sociocultural perspective on professional agency. Here teaching is conceptualised as an ongoing interplay between teachers’ knowledge, skills and personal goals, and the characteristics of the social, institutional and policy settings in which they work. Our analysis shows that navigating the ensuing continuities and contradictions results in many different expressions of teacher agency, e.g. loss of autonomy and trust, pushing back, subversion, transfer of authority, and creative tensions. Typically, an individual teacher’s enactment of these reforms involved several of these expressions of agency. We demonstrate that the sociocultural perspective provides insights into teachers’ responses to education policy reform likely to be missed by studies that focus largely on individual teacher knowledge/beliefs about reform or skills in ‘implementing’ reform practices. 相似文献

In 2014 a new policy for special educational needs and disability (SEND) provision was introduced in England. As it has been the case in countries where SEND reforms were introduced, these changes raised challenges and opportunities for the professionals supporting children with SEND. However, to date, little systematic and large-scale evidence has been made available on how professionals perceive these changes. In this study, the views of 349 professionals were ascertained using a semi-structured online survey. The results revealed that although many professionals agreed in principle with some of the key changes introduced, several constraints were reported including tight timelines, budget cuts, and difficulties in the collaboration between education, health and care, suggesting a rather fragmented implementation of the new policy. No significant differences were found between groups of professionals for most items, however educational psychologists and special needs co-ordinators disagree on the extension of the provision age range, on how well the children’s needs are described in the education, health and care plans, and on the professional requirements of this process. The findings are discussed in light of their implications for meeting children’s needs and in comparison with other policy changes worldwide. 相似文献

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions. 相似文献

Low energy consumption is one of the main challenges for wireless video transmission on battery limited devices. The energy invested at the lower layers of the protocol stack involved in data communication, such as link and physical layer, represent an important part of the total energy consumption. This communication energy highly depends on the channel conditions and on the transmission data rate. Traditionally, video coding is unaware of varying channel conditions. In this paper, we propose a cross-layer approach in which the rate control mechanism of the video codec becomes channel-aware and steers the instantaneous output rate according to the channel conditions to reduce the communication energy. Our results show that energy savings of up to 30% can be obtained with a reduction of barely 0.1 dB on the average video quality. The impact of feedback delays is shown to be small. In addition, this adaptive mechanism has low complexity, which makes it suitable for real-time applications. 相似文献

A sociocultural view of learning proposes that learning involves becoming enculturated into a community of practice. A step
along the way is learning to use the specialized language of such a community, as language is a crucial tool that regulates
participation, mediates cognition and plays a central role in the development of thought. Problem-based learning (PBL), with
its emphasis on collaborative discourse, provides opportunities for students to develop the conceptual language of a discipline,
which in turn affects cognition. In a problem-based undergraduate Educational Psychology course, many psychological theories,
concepts and principles are introduced to pre-service teachers. During the course, as students learn through problem solving,
they engage with new knowledge. This evolving knowledge requires new discourse structures that will allow students to express
their new ideas and that will ultimately structure students' ways of knowing. The content of group and individual artifacts
is analyzed to examine how PBL influences students' language and knowledge development over the course of the semester in
an Educational Psychology class (n = 34). The goal of this paper is to present these analyses and to discuss how the change affects students' language and knowledge. 相似文献

Entrepreneurial transformations in the Swedish University system: the case of Chalmers University of Technology 总被引：2，自引：0，他引：2
Since the beginning of the 1990s, Sweden has been transforming its national research policy into policy for innovation. One of the bottom up responses to this top d initiative has been an attempt on the part of some Swedish universities to transform themselves into entrepreneurial institutions. This paper uses a case study of one particular Swedish University; Chalmers University of Technology’s transformation process to reflect on the new research policy. Chalmers’ journey is examined against the backdrop of the changing national climate for universities as well as local factors within the university itself.The case confirms existing knowledge in that it shows that creating an entrepreneurial university takes several years as both infrastructural and cultural changes are necessary to achieve success. The case also shows that despite the long history of public-private in Sweden, the new emphasis on commercialisation and commodification of knowledge creates some degree of role uncertainty for universities. The paper concludes that one of the elements required for Swedish innovation policy is macro (policy vision and implementation) and micro (university organisation) level flexibility and diversity. 相似文献
