Towards a Taxonomy of Mentoring   总被引:1,自引:1,他引:0  
Initial Teacher Education in England and Wales is currently undergoing substantial change. In particular, the government has insisted on increased time for school‐based work, on the development of training partnerships between schools and higher education providers, including the transfer of training funds from universities to schools, and on a competence model of assessment. This article focuses on one of the new partnership training courses. Using two of the areas of competence, Subject Knowledge and Subject Application, it explores the reality of partnership from the perspectives of students, school mentors and university tutors as they work through the first year of the new course. Finally, the writers present a series of questions for all those involved as the basis for developing such courses and for ensuring the quality of teacher education.  相似文献

This article describes the differences between mentors’ and protégés’ expectations and realities regarding mentoring relationships and goals. Faculty and senior undergraduate mentors and female undergraduate protegés who participated in a formal, university mentoring programme at the University of Idaho, organised by the institution’s Women’s Centre, were asked to describe their ideal and actual mentoring relationship through metaphor; the responses were analysed qualitatively to explore protégés’ and mentors’ expectations and experiences. Results indicate that protégés held more traditional and hierarchical mentoring ideals at the beginning of the programme and that most mentoring ideals differed from actual experiences. Given this disparity and because metaphorical processes have the capacity to enhance mentoring experiences due to their generative and expansive capacities, we suggest that metaphors be employed in explicit ways to align expectations and realities between mentors’ and protégés’ expectations through shared reflection. We conclude with metaphorical exercises that can be used in formal mentoring programmes in higher education to help participants negotiate expectations and help organise relationships in ways that are aligned with the mission and goals of particular mentoring programmes.  相似文献

In both the UK and Australia there has been a recent move to use citation analysis in the evaluation of the research of individuals. In particular, the future UK Research Excellence Framework (REF), proposes using citation data in the research evaluation of articles published as recently as the year prior to the evaluation. In response to this move, this research develops an indicator at the level of individual articles that, when normalized, can supplement peer review. The new hybrid indicator is the weighted sum of two indicators in common usage: the article’s total number of citations in a citation window, and the Impact Factor of the journal in which the article was published. This research compares this new indicator with the article’s total number of citations in a longer citation window (the standard indicator of article impact). For citation windows of 0 or 1 years, the correlation of the simplified weighted sum with long-term citation is substantially higher than the correlation of the standard indicator of article citation with long-term citation. Moreover, for citation windows of as long as 3 years the standard indicator of citation correlates significantly with the month of publication, in that articles published earlier in the year are on average more highly cited than those published later in the year. By contrast, the skewing of the simplified weighted sum towards articles published early in the year is considerably less than that of the standard indicator.  相似文献

ABSTRACT

This paper uses visualisations of life trajectories drawn from the 1958 National Child Development Survey to show how this generation refused linear narratives of mobility in favour of jags and turning points. We argue that these visualisations demonstrate the limitations of conventional class-based interpretations of social mobility. . We show how these jags represent moments of switching between public and private lives, demonstrating the interruptions which this generation display. We argue that these visualisations are consistent with the distinctive historical conditions ofthis generation, especially its female members, We conclude that more studiesof popular identities of social mobility are needed.  相似文献

Early social experiences, such as caregiver scaffolding, play a crucial but disputed role in the emergence of prosociality. A longitudinal experiment examined how explicit scaffolding—such as encouragement or praise—influences helping late in the first year, when helping emerges. Eighty-three infants (40 female, 6–9 months, 54% White, 17% Hispanic/Latinx, 16% Asian) participated in up to 10-weekly home visits in which they could help an experimenter in a novel activity. Data were collected in Santa Cruz, CA between February 2018 and August 2019. Compared to the control condition, explicit scaffolding increased helping by handing out-of-reach objects, η2 = .02, and, among younger infants, by cleaning up. Helping also increased with age and visit number. Using a new paradigm, this research provides experimental evidence for how adults’ scaffolding shapes the emergence of helping in infancy.  相似文献

A difficult question in the philosophy of sport concerns how winning athletes should perform in uneven contests in which victory has been secured well before the competition is over. Nicholas Dixon, the protagonist in the ongoing debate, argues against critics who urge following an 'anti-blowout' thesis that there is nothing intrinsically wrong with running up the score. We engage this debate, providing much needed distinctions, and draw on Aristotelian resources to explore a framework by which to understand competing claims found within the literature.  相似文献

Abstract

Complex training, a combination of resistance training and plyometrics is growing in popularity, despite limited support for its efficacy. In pre- and early pubertal children, the study of complex training has been limited, and to our knowledge an examination of its effect on anaerobic performance characteristics of the upper and lower body has not been undertaken. Furthermore, the effect of detraining after complex training requires clarification. The physical characteristics (mean±s) of the 54 male participants in the present study were as follows: age 12.3 ± 0.3 years, height 1.57 ± 0.07 m, body mass 50.3 ± 11.0 kg. Participants were randomly assigned to an experimental (n = 33) or control group (n = 21). The training, which was performed three times a week for 12 weeks, included a combination of dynamic constant external resistance and plyometrics. After training, participants completed 12 weeks of detraining. At baseline, after training and after detraining, peak and mean anaerobic power, dynamic strength and athletic performance were assessed. Twenty-six participants completed the training and none reported any training-related injury. Complex training was associated with small increases (≤5.5%) in peak and mean power during training, followed by decreases of a similar magnitude (≤ ?5.9%) during detraining (P < 0.05). No changes or minor, progressive increases (≤1.5%) were evident in the control group (P > 0.05). In the experimental group, dynamic strength was increased by 24.3 – 71.4% (dependent on muscle group; P < 0.01), whereas growth-related changes in the control group varied from 0 to 4.4% (P > 0.05). For 40-m sprint running, basketball chest pass and vertical jump test performance, the experimental group saw a small improvement (≤4.0%) after training followed by a decline (≤ ?4.4%) towards baseline during detraining (P < 0.05), whereas the control group experienced no change (P > 0.05). In conclusion, in pre- and early pubertal boys, upper and lower body complex training is a time-effective and safe training modality that confers small improvements in anaerobic power and jumping, throwing and sprinting performance, and marked improvements in dynamic strength. However, after detraining, the benefits of complex training are lost at similar rates to other training modalities.  相似文献

Abstract

The aim of the study was to compare physiological responses between runners adapted and not adapted to deep water running at maximal intensity and the intensity equivalent to the ventilatory threshold. Seventeen runners, either adapted (n = 10) or not adapted (n = 7) to deep water running, participated in the study. Participants in both groups undertook a maximal treadmill running and deep water running graded exercise test in which cardiorespiratory variables were measured. Interactions between adaptation (adapted vs. non-adapted) and condition (treadmill running vs. deep water running) were analysed. The main effects of adaptation and condition were also analysed in isolation. Runners adapted to deep water running experienced less of a reduction in maximum oxygen consumption ([Vdot]O2max) in deep water running compared with treadmill running than runners not adapted to deep water running. Maximal oxygen consumption, maximal heart rate, maximal ventilation, [Vdot]O2 at the ventilatory threshold, heart rate at the ventilatory threshold, and ventilation at the ventilatory threshold were significantly higher during treadmill than deep water running. Therefore, we conclude that adaptation to deep water running reduces the difference in [Vdot]O2max between the two modalities, possibly due to an increase in muscle recruitment. The results of this study support previous findings of a lower maximal and submaximal physiological response on deep water running for most of the measured parameters.  相似文献
