This paper provides a review of school leadership preparation and development in Australia through considering the requirements for becoming a principal, how leadership preparation and development occurs, and consideration of recent developments to provide an Australian standard for school leaders. Australian educators have relied mostly on a self-identification and self-managed system in which individuals decide that they want to pursue leadership opportunities and then seek out the support and experiences to help them. Support is available and provided through system, university, and service organization programmes, and the support of colleagues and senior leaders in schools. Whilst there is an extensive range of support provided by systems, universities and service organizations, there is little evidence of their impact on schools. At the school level there needs to be far greater support in identifying and developing leaders. Developments in creating a national leadership standard might lead to some type of credentialing programme that could allow individuals to benchmark their development, and ensure that preparation and support programmes are of the highest quality. An alternative view is to reinforce greater individual responsibility for leadership development and career progress, encourage schools and systems to focus less on individual leadership and more on collective leadership, and consider more innovative ways of providing leadership development.  相似文献

Novice members of a Norwegian national rater panel tasked with assessing Year 8 pupils’ written texts were studied during three successive preparation sessions (2011–2012). The purpose was to investigate how the raters successfully make use of different decision-making strategies in an assessment situation where pre-set criteria and standards give a rather strict framework. The data sources were the raters’ pair assessment dialogues. The analysis shows that the raters use a ‘shared standards strategy’, but when reaching agreement on text quality they also seem to make very good use of assessment strategies related to their work as writing teachers. Moreover, asymmetries in knowledge and participation among raters contribute to creating an image of writing assessment as a challenging hermeneutic practice. It is suggested that future rater preparation would gain from being attentive to the internalised assessment practices teachers bring to the fore when working as raters.  相似文献

There is a growing concern about the struggles of early career teachers and an understandable questioning of the preparation being offered by teacher education courses. Are our preservice teachers being given workable strategies and techniques to allow them to survive the early years? Is it strategies and techniques that are primarily at issue here? Could it be that there is something more fundamental, to do with an underlying philosophical understanding about human nature, the desire to learn and the need to relate? I want to suggest that instruction about strategies and techniques is too often built on an insecure and incompatible foundation of assumptions about the nature of the world of sentient beings and their relationships. Ontology matters. Philosopher Spinoza divided the world of thought into ideas that were adequate – contributing to our well-being, potency and happiness – and those that were inadequate – leading us to feel weak, at the mercy of outside forces, and sad. I want to argue, with Spinoza, that inadequate ontologies lead to a sense of impotence and frustration, and that adequate ideas – a stronger ontology – can underpin and sustain a more durable pedagogy. I explore this idea by looking at some classroom events through a Spinozean lens.  相似文献

Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform efforts. Nonetheless, there is a dearth of research on conceptualizing explanation in science education. Using a philosophically guided framework—the Nature of Scientific Explanation (NOSE) framework—the study aims to elucidate and compare college freshmen science students', secondary science teachers', and practicing scientists' scientific explanations and their views of scientific explanations. In particular, this study aims to: (1) analyze students', teachers', and scientists' scientific explanations; (2) explore the nuances about how freshman students, science teachers, and practicing scientists construct explanations; and (3) elucidate the criteria that participants use in analyzing scientific explanations. In two separate interviews, participants first constructed explanations of everyday scientific phenomena and then provided feedback on the explanations constructed by other participants. Major findings showed that, when analyzed using NOSE framework, participant scientists did significantly “better” than teachers and students. Our analysis revealed that scientists, teachers, and students share a lot of similarities in how they construct their explanations in science. However, they differ in some key dimensions. The present study highlighted the need articulated by many researchers in science education to understand additional aspects specific to scientific explanation. The present findings provide an initial analytical framework for examining students' and science teachers' scientific explanations.  相似文献
