The article reviews the research on teacher effectiveness and develops the case for a model of teacher effectiveness in which differential effectiveness is incorporated. Five problems with current concepts of teacher effectiveness are identified: undue influence of available techniques upon the concept; emphasis on school, to the detriment of teacher, effectiveness; tenuous relationship to teacher improvement; narrowness of operational definitions in research; and the development of generic, rather than differentiated, models. In addition the failure of existing models to explain variance in pupil outcome at the classroom level, the neglect of teacher self-evaluation, and the restricted measures of pupil outcomes are noted. A differential model is proposed incorporating five dimensions of difference. These refer to teacher activity, outside as well as inside the classroom; curriculum subject; pupil background factors; pupil personal characteristics; cultural and organisational contexts of teaching. The developmental functions of such a model for research and for teacher appraisal are explored. Four problems for implementing a differentiated model are raised: complexity, stakeholder expectations, values, and policy acceptability. These are considered in the light of the controversial Hay McBer model in England and of models developed in Europe and the USA in the early decades of the last century.  相似文献

Recent policy in England has suggested that educational outcomes will be raised if schools specialise in particular subjects. In contrast, calls for the reform of 16–19 education have suggested that these outcomes will be improved if students become less specialised in their studies. At present, there is a limited evidence base from which to judge these arguments. In particular, we do not know the extent to which students’ achievements in 16–19 education are higher when they choose subjects which play to their perceived strengths. We also do not know whether students are more likely to choose to study subjects taught by more effective departments. That is, outcomes may be affected by the relative strengths of students or departments in circumstances where there is freedom to choose. In this paper we provide evidence of the existence and strength of these relationships. This evidence suggests that reducing the scope within schools for specialisation or competition will reduce average student attainment and these effects ought to be taken into account when evaluating alternative curriculum policies.  相似文献

This paper is concerned with the ethics of relationships in doctoral supervision. We give an overview of four paradigms of doctoral supervision that have endured over the past 25 years and elucidate some of their strengths and limitations, contextualise them historically and consider their implications for doctoral supervision in the contemporary university. Two common threads across the four paradigms are a view of doctoral supervision as pedagogical practice and that supervisors have primary responsibility for the supervision of doctoral students. We challenge these assumptions. In their place, we propose that the goal of doctoral supervision is praxis and that this involves a learning alliance between multiple institutional agents grounded in a relational ethics of mutual responsibility.  相似文献

Since the 1970s, school effectiveness research has looked for process-variables filling the black box between mainly structural school features and cognitive outcomes in students. Two concepts came to the fore: school climate and school culture. Both concepts are currently used interchangeably, although it is open to debate whether both are actually the same thing. Because of the way culture and climate are defined and subsequently measured, we propose school culture is a better frame from which to study school effectiveness. This article goes through the premises of perceptual measurement usually overlooked in climate research, and we demonstrate empirically by means of very basic and simple methods and techniques that perceptual measurement and measurement based on assumptions are different approaches and might yield totally different results on an aggregated level. We conclude by demonstrating how culture can be probed and integrated in the models traditionally used in school effectiveness research in an advantageous and theoretically sound way.  相似文献

This paper provides some background information about the Strategic Capacity Building for Australian Educational Research initiative: a joint program of work sponsored by the Australian Association for Research in Education and the Australian Council of Deans of Education. In addition, it offers some broader analysis of the contexts within which Australian Educational Research is being framed and judged, and argues that leaders of educational research need to become more adept at finding and creating spaces in which important policy battles can be won.  相似文献

ABSTRACT

Geragogy as a part of gerontology seems to be established in aging societies. Also, geragogy as a form of education for elderly people, learning in the third age, is nowadays an integrated part of agogy. On the other hand, the increase in the number of people of the fourth age, the oldest of the old, handicapped elderly people in nursing homes, is hardly considered in the geragogical discussion. Integrative geragogy in the field of care facilities is given only marginal consideration. In this article we want to present integrative geragogy as a basic part of educational gerontology. We present it as interacting closely with therapeutic education and social work, dealing especially with potentials of the oldest of the old and mentally handicapped elderly people. An outline of the international discussion and the history of geragogy in Germany shows the state-of-the-art in geragogy today. A specific theory and praxeology of integrative geragogy is also presented.  相似文献

遗传多样性保护对于全球农业发展至关重要,而有效的保护与农民对不同作物的种植选择关系密切.目前在中国北方偏远地区,农民仍以种植小杂粮为主,所采用品种多为具有广泛遗传多样性的地方品种.通过对该地区农民对不同品种小杂粮选择种植的调查,基于我们的作物选择模型,得出市场不完全和收入水平低是农民种植小杂粮作物的重要原因.建议政府在遗传多样性保护中发挥更重要的作用.  相似文献

In recent years, governance and public participation have developed into key notions within both policy discourse and academic analysis. While there is much discussion on developing new modes of governance and public participation, little empirical attention is paid to the public's perception of models, possibilities and limits of participation and governance. Building on focus group data collected in Austria within the framework of a European project, this paper explores lay people's visions and versions of government, governance and participation for two biomedical technologies: post-natal genetic testing and organ transplantation. Building on this analysis, we show that people situate their assessments of public participation against the background of rather complex lay models of the governance and government of the respective technology. Because these models are very different for the two technologies, participation also had very different connotations, which were deeply intertwined with each socio-technical system. Building on these findings we argue for a more technology-sensitive approach to public participation.  相似文献

The principle of polyrepresentation offers a theoretical framework for handling multiple contexts in information retrieval (IR). This paper presents an empirical laboratory study of polyrepresentation in restricted mode of the information space with focus on inter and intra-document features. The Cystic Fibrosis test collection indexed in the best match system InQuery constitutes the experimental setting. Overlaps between five functionally and/or cognitively different document representations are identified. Supporting the principle of polyrepresentation, results show that in general overlaps generated by three or four representations of different nature have higher precision than those generated from two representations or the single fields. This result pertains to both structured and unstructured query mode in best match retrieval, however, with the latter query mode demonstrating higher performance. The retrieval overlaps containing search keys from the bibliographic references provide the best retrieval performance and minor MeSH terms the worst. It is concluded that a highly structured query language is necessary when implementing the principle of polyrepresentation in a best match IR system because the principle is inherently Boolean. Finally a re-ranking test shows promising results when search results are re-ranked according to precision obtained in the overlaps whilst re-ranking by citations seems less useful when integrated into polyrepresentative applications.  相似文献
