To maintain a professional identity, teachers are to some degree dependent on their student's mental representations of, and interactions with, them. This affords students’ relational power over teachers possibly invoking a unique form of attachment dependence and responding in some teachers. Data reported in this paper were drawn from a larger research project which asked 11 questions about the nature of the teacher–student relationship. The attachment styles of 291 pre-service and experienced elementary and secondary school teachers were examined using the Experience in Close Relationships Questionnaire (ECR). Significant differences were found for teacher type (elementary versus secondary), experience, age and gender. Implications for classroom relationships, management and teacher education are discussed.  相似文献

Fifteen Portuguese children with dyslexia, aged 9–11 years, were compared with reading and chronological age controls with respect to five indicators related to the phonological deficit hypothesis: the effects of lexicality, regularity, and length, implicit and explicit phonological awareness, and rapid naming. The comparison between groups indicates that Portuguese children with dyslexia have a phonological impairment which is revealed by a developmental deficit in implicit phonological awareness and irregular word reading (where younger reading level controls performed better than dyslexics) and by a developmental delay in decoding ability and explicit phonological awareness (where dyslexics matched reading level controls). These results are discussed in relation to the idea that European Portuguese is written in an orthography of intermediate depth.  相似文献

This paper highlights the crucial role of phonological instruction in early second language English learning. Although older learners can acquire grammar and vocabulary efficiently, younger learners appear to have a greater facility with the learning of sounds. Thus, it makes good sense to focus on articulatory skills for these early learners. By comparing the developmental norms in phonology between an L1 (Cantonese in this study) and an L2, detailed predictions can be provided to guide the process of early phonological instruction. It is important that the teaching of articulation should not be reduced to non‐engaging lessons that can be characterised as ‘drill and kill’. Instead, a framework for improving the articulation of children learning English as a second language is proposed. What is unique about this proposal is that it represents the first attempt in Hong Kong to specify and integrate research findings concerning developmental speech norms with existing teaching practice.  相似文献

In the past few decades, much research has documented the importance of users as sources of innovations. Over the last 10 years, Research Policy alone has published 56 research articles investigating this phenomenon. We ask to what degree the findings of users as innovators have been absorbed by decision-makers responsible for new product development (managers) and by those who shape the contextual conditions for innovation (policy makers and public administration). A realistic perception of the sources of innovation is important as it constitutes the basis for a rational allocation of resources and thus indirectly impacts the innovation performance of companies and societies at large.In a large-scale survey of n?=?1500 decision-makers, we found support for a substantial underestimation of users as a source of innovation: While the true proportion of user innovation among the most valuable 1678 innovations in nine industries is 54.4% (as established in existing research articles), decision-makers estimate it to be 21.7%. A content analysis of transfer media (450 academic textbooks, popular innovation books, and business articles) underscores this theory-practice gap: Of 3469 text paragraphs dealing with the sources of innovation, only 2.7% mention users as innovators. We develop six propositions on the reasons for and consequences of this underestimation that may serve as a starting point for future research and practical consequences.  相似文献

Real-world cycling performance depends not only on exercise capacities, but also on efficiently traversing the bicycle through the terrain. The aim of this study was to determine if it was possible to quantify the braking done by a cyclist in the field. One cyclist performed 408 braking trials (348 on a flat road; 60 on a flat dirt path) over 5 days on a bicycle fitted with brake torque and angular velocity sensors to measure brake power. Based on Newtonian physics, the sum of brake work, aerodynamic drag and rolling resistance was compared with the change in kinetic energy in each braking event. Strong linear relationships between the total energy removed from the bicycle-rider system through braking and the change in kinetic energy were observed on the tar-sealed road (r2 = 0.989; p < 0.0001) and the dirt path (r2 = 0.952; p < 0.0001). T-tests revealed no difference between the total energy removed and the change in kinetic energy on the road (p = 0.715) or dirt (p = 0.128). This study highlights that brake torque and angular velocity sensors are valid for calculating brake power on the disc brakes of a bicycle in field conditions. Such a device may be useful for investigating cyclists’ ability to traverse through various terrains.  相似文献

This paper explores the approaches adopted by high-level field athletics coaches when attempting to refine an athlete’s already well-established technique (long and triple jump and javelin throwing). Six coaches, who had all coached multiple athletes to multiple major championships, took part in semi-structured interviews focused upon a recent example of technique refinement. Data were analysed using a thematic content analysis. The coaching tools reported were generally consistent with those advised by the existing literature, focusing on attaining “buy-in”, utilising part-practice, restoring movement automaticity and securing performance under pressure. Five of the six coaches reported using a systematic sequence of stages to implement the refinement, although the number and content of these stages varied between them. Notably, however, there were no formal sources of knowledge (e.g., coach education or training) provided to inform coaches’ decision making. Instead, coaches’ decisions were largely based on experience both within and outside the sporting domain. Data offer a useful stimulus for reflection amongst sport practitioners confronted by the problem of technique refinement. Certainly the limited awareness of existing guidelines on technique refinement expressed by the coaches emphasises a need for further collaborative work by researchers and coach educators to disseminate best practice.  相似文献

The relative age effect (RAE) is a common phenomenon in youth sport, whereby children born early in the selection year are more likely to experience success and to sustain participation. There is a lack of research investigating variables which influence RAEs within track and field athletics. Such information is vital to guide policies in relation to competition structure, youth development squads and coach education. A database of competition results was analysed to determine the extent to which RAEs were present in track and field athletics in the United Kingdom. Subsequent analyses examined whether age, sex, event and skill level influenced the RAE. Examination of 77,571 records revealed that RAEs were widespread, but most pronounced during Under 13 (U13) competitions; that is, during athletes’ first exposure to formal track and field competition. Sex, event and skill level further influenced the existence and magnitude of RAEs at different age grades. Relative age is a key influencing factor within track and field athletics, especially at the youngest age category. Consequently, national governing bodies need to consider what administrative and stakeholder initiatives are necessary to minimise the effects of RAEs on young athletes’ early experiences of competition.  相似文献

Key ideas in the work of Michel Foucault are explored and applied to the organized pursuit of knowledge in higher education. His association of power and knowledge accounts for deeply rooted practices in higher education that would need to be mediated or overcome for there to be a revolution in inquiry to occur, such as the one advanced by Nicholas Maxwell. Foucault’s concepts of disciplinary power and bio-power, and how they act to manage the behavior of free citizens, are described. These concepts are then applied to free inquiry, to show how the activity of individual inquirers is managed and how critical inquiry is controlled. The management of inquiry involving four norms, two of them intrinsic to inquiry and the other two extrinsic, is explained. The potential of Foucault’s concept of discursive formations is introduced as a means of reconceiving inquiry to overcome these impediments to a revolution in inquiry.  相似文献

Despite a groundswell of evidence for transformative education, manifestos for ‘transformative pedagogy for global citizenship’ remain under-theorized and pay limited attention to implications for practice. This paper connects theory and practice through analyzing a curriculum development project that sought to produce a framework for ‘engaged global citizens’. It considers the political and philosophical framings of the self and other, citizen and world, that underlie this empirical work, especially with reference to reflexivity, hermeneutics, democratic engagement and co-production. The resultant pedagogical framework, based upon concepts of transformative learning, attempted to undercut the homogenizing tendencies within global citizenship education (GCE). This discussion highlights the tensions and reifying effects of educational frameworks such as the Teaching Excellence Framework in the UK and the proposed framework for ‘global competence’ in the 2018 Programme for International Student Assessment. Evidence is presented that frameworks which attempt to make explicit educational phenomena and processes are overdetermined by efficacy and metrics that become perverse ends in themselves. While the anticipated project output here was the framework itself, the substantive output was, in fact, practical: namely the ongoing deliberation and reflection upon the discourses that both do and undo the task of locating the transformative dimension of GCE.  相似文献
