Professional development for teachers: a world of change   总被引:1,自引:1,他引:0  
As the industrialised world shifted to an interdependent and global society, formal schooling was quickly recognised as a major factor in achieving a knowledge society of lifelong learners capable of transforming and revitalising organisations. Teachers were encouraged to engage in learning together to improve teaching and, by extension, improve learning for the children in their care. This article identifies three emerging trends intended to broaden teachers' learning and enhance their practices through continuous professional development: glocalisation, mentoring, and re‐thinking teacher evaluation. The body of the article indicates how these three trends are unfolding in Australia, England, Latvia, the Republic of Ireland, Scotland, Taiwan, and the USA.

However, teachers cannot bring about necessary changes without organisational and systemic change; namely, collaboration with governmental agencies and other institutions. The authors suggest that transforming schooling in the twenty‐first century depends on education policies being supported by expanded teacher participation in education policy‐making, more coherent governmental policies across agencies, and collaborative, differentiated models for career‐long continuing professional development.  相似文献

Exercise has been demonstrated to have considerable effects upon haemostasis, with activation dependent upon the duration and intensity of the exercise bout. In addition, markers of coagulation and fibrinolysis have been shown to possess circadian rhythms, peaking within the morning (0600–1200?h). Therefore, the time of day in which exercise is performed may influence the activation of the coagulation and fibrinolytic systems. This study aimed to examine coagulation and fibrinolytic responses to short-duration high-intensity exercise when completed at different times of the day. Fifteen male cyclists (VO2max: 60.3?±?8.1?ml?kg?1?min?1) completed a 4-km cycling time trial (TT) on five separate occasions at 0830, 1130, 1430, 1730 and 2030. Venous blood samples were obtained pre- and immediately post-exercise, and analysed for tissue factor (TF), tissue factor pathway inhibitor (TFPI), thrombin–anti-thrombin complexes (TAT) and D-Dimer. Exercise significantly increased plasma concentrations of TF (p?p?p?p?p?=?.004) and TFPI (p?=?.031), with 0830 greater than 1730 (p .001), while 1730 was less than 2030?h (p?=?.008), respectively. There was no significant effect of time of day for TAT (p?=?.364) and D-Dimer (p?=?.228). Power output, TT time and heart rate were not significantly different between TTs (p?>?.05); however, percentage VO2max was greater at 1730 when compared to 2030 (p?=?.04). Due to a time-of-day effect present within TF, peaking at 0830, caution should be applied when prescribing short-duration high-intensity exercise bout within the morning in populations predisposed to hypercoagulability.  相似文献

Background: The researchers involved in this study work at Exeter Health library and at the Complementary Medicine Unit, Peninsula School of Medicine and Dentistry (PCMD). Within this collaborative environment it is possible to access the electronic resources of three institutions. This includes access to amed and other databases using different interfaces. Objectives: The aim of this study was to investigate whether searching different interfaces to the amed allied health and complementary medicine database produced the same results when using identical search terms. Methods: The following Internet‐based amed interfaces were searched: DIALOG DataStar; EBSCOhost and OVID SP_UI01.00.02. Search results from all three databases were saved in an endnote database to facilitate analysis. A checklist was also compiled comparing interface features. Results: In our initial search, DIALOG returned 29 hits, OVID 14 and Ebsco 8. If we assume that DIALOG returned 100% of potential hits, OVID initially returned only 48% of hits and EBSCOhost only 28%. In our search, a researcher using the Ebsco interface to carry out a simple search on amed would miss over 70% of possible search hits. Subsequent EBSCOhost searches on different subjects failed to find between 21 and 86% of the hits retrieved using the same keywords via DIALOG DataStar. In two cases, the simple EBSCOhost search failed to find any of the results found via DIALOG DataStar. Conclusions: Depending on the interface, the number of hits retrieved from the same database with the same simple search can vary dramatically. Some simple searches fail to retrieve a substantial percentage of citations. This may result in an uninformed literature review, research funding application or treatment intervention. In addition to ensuring that keywords, spelling and medical subject headings (MeSH) accurately reflect the nature of the search, database users should include wildcards and truncation and adapt their search strategy substantially to retrieve the maximum number of appropriate citations possible. Librarians should be aware of these differences when making purchasing decisions, carrying out literature searches and planning user education.  相似文献

The coteaching model for teacher preparation has emerged in recent years as an alternative to the traditional student teaching or practicum experience. Several studies have investigated the process of coteaching and its impact on participants during the actual experience; however, few depict participants’ experiences once they obtain positions and begin to teach independently. This collective case study explored two urban high school teachers’ (Jen and Ian) practices during the induction period after taking part in the coteaching model for student teaching. Using a sociocultural analytic framework, we found that the participants’ agency as beginning teachers was not constrained by their coteaching experiences. Rather, they were able to continue to draw on some of the successful practices they had in coteaching, such as shared reflection, shared responsibility, cogenerative dialogues, and building relationships with students. In addition to describing the coherence and contradictions between Ian’s and Jen’s practices during coteaching and in their beginning years of inservice teaching, we also discuss the ways that they became collaborators in our ethnographic research.

The present study used cross‐lagged panel analyses to test longitudinal associations among emotion regulation, prefrontal cortex (PFC) function, and depression severity in adolescent girls. The ventromedial and dorsomedial PFC (vmPFC and dmPFC) were regions of interest given their roles in depression pathophysiology, self‐referential processing, and emotion regulation. At ages 16 and 17, seventy‐eight girls completed a neuroimaging scan to assess changes in vmPFC and dmPFC activation to sad faces, and measures of depressive symptom severity and emotion regulation. The 1‐year cross‐lagged effects of dmPFC activity at age 16 on expressive suppression at age 17 and depressive symptomatology at age 17 were significant, demonstrating a predictive relation between dmPFC activity and both suppression and depressive severity.  相似文献

Schools' ability to manage student misbehavior rests largely on students' perceptions of the discipline system and authority. According to the procedural justice perspective, when schools use discipline practices students perceive as unfair, they fail to see authority as legitimate, making them less likely to comply with rules and demand. Youth Court, a peer adjudication program, has been implemented in schools as an alternative to punitive policies. While effective, there is no current research that examines if Youth Court creates procedural justice and legitimate authority. Using qualitative data from three urban schools, this study investigates the fairness of Youth Court procedures within a procedural justice framework, as well as perceptions of primary discipline practices and authority. Findings revealed that each school still largely uses punitive policies that create procedural unfairness and undermine legitimate authority. Additionally, findings indicate Youth Court utilizes practices that allow for procedural justice that foster legitimate authority.  相似文献

This research uses an active listening approach within a narrative inquiry methodology to consider the views of three teenage males aged 15–17 years on the topic of missing education. Missing education is a term used to describe children and young people (CYP) not receiving a suitable education or being on a school roll. The participants’ accounts were analysed using a Voice-Centred Relational Method to identify the complex interplay of systemic factors, the importance of individual experience and supportive adult–pupil relationships. The reflective accounts presented in this paper highlight implications for active and effective listening to CYP. A model was created to support the approaches educational psychologists (EPs) could use to support school staff, parents and other professionals in their work with individuals “missing education”.  相似文献

The distinction between grandiose and vulnerable narcissism is new to the child literature, but initial findings suggest that it may have important implications for understanding adjustment. This study examined how expressions of narcissism in children influence their reactions to a mild egothreats experience. Children (N = 124; aged 8–12 years) completed self-ratings before and after doing a brief but challenging task. Negative emotions, self-conscious emotions, and performance estimates were measured. Regression analyses showed that, even after controlling the effects of self-esteem and temperament, vulnerable narcissism was related to increased hostility, anger, and shame, whereas grandiose narcissism was related to inflated performance estimates following the task. These results demonstrate the unique roles of grandiose and vulnerable narcissism in children.  相似文献
