In order to evaluate the effectiveness of an experimental elementary mathematics field experience course, we have designed
a new assessment instrument. These video-based prediction assessments engage prospective teachers in a video analysis of a
child solving mathematical tasks. The prospective teachers build a model of that child’s mathematics and then use that model
to predict how the child will respond to a subsequent task. In this paper, we share data concerning the evolution and effectiveness
of the instrument. Results from implementation indicate moderate to high degrees of inter-rater reliability in using the rubric
to assess prospective teachers’ models and predictions. They also indicate strong correlation between participation in the
experimental course and prospective teachers’ performances on the video-based prediction assessments. Such findings suggest
that prediction assessments effectively evaluate the pedagogical content knowledge that we are seeking to foster among the
prospective teachers. 相似文献
In this article we address "language approach" data as a key variable in quantitative, large-scale research on educational achievement, focusing on our work for the Achievements of Deaf Pupils in Scotland (ADPS) project. The complexity of approaches is addressed, with a particular focus on a "no-exclusion" model of service. In this context 3 years of language-related data are discussed, using constructions of language variables that take into account the variability in deaf pupils' hearing loss levels, types of provision, and professional practice. We see this as a necessary first step toward offering a nuanced context for understanding patterns in the educational outcomes among the ADPS population to be reported in a later article. The ADPS data on language approach can reveal general patterns at macro levels: our analysis suggests that, in Scotland, the extent and quality of British Sign Language/English provision may be determined more by local factors than by linguistic requirements and that ostensibly responsive policies can mask a limited spectrum for pupils and their families. However, the ADPS data are insufficiently sensitive to detailed and local variations to reflect the full complexity of language situations over time-a situation which represents an ongoing challenge for all long-term, large-scale studies. 相似文献
In this article, prevailing professional, business and managerial discourses of team leadership are ‘troubled’ by some feminist critiques and analyses of collectivity and gendered discursive relations of power. I draw on a study of primary school co‐principalships to describe and reflect on Karen’s (a pseudonym) accounts of her personal and shared leadership practices within a three teacher co‐principalship. The article indicates how feminist consciousness, politics and relationships can contribute to social, cultural and organizational change within ‘mainstream’ institutions.11. I am grateful to the reviewers of this article, one of whom made this point.View all notes It also explores how pre‐constructed discourses about gender, class and leadership, can be unwittingly stitched back into an individual’s collaborative practices, limiting the potential for democratic change. My aim is to contribute to the kind of work called for by Davies when she argued that if we are alerted to the work being done by the various discourses we are invoking, then we can more effectively reflect on how limiting and disempowering discursive constructions can be challenged and changed. 相似文献

London is one of the world's foremost music cities. Using a statistical approach developed in earlier studies of music in the United Kingdom (NMC, 1996; NMC, 1999), this chapter presents the results of a survey commissioned by London Arts from researchers at the University of Westminster. The chapter draws together available data oh the commercial and public sectors of the industry, on live performances and their audiences, on education and training and on exports. This data has been supplemented by new research, notably in the area of live performance and in identifying geographical ‘clusters’ of music business firms in certain areas of inner London.
Among the key findings of the research are that consumer spending represents some 90 per cent of the £1.1 billion total spending on music in London; consumers spent more on concert tickets and entrance charges for music of all types than on CDs and other soundcarriers; music provides the equivalent of 34,000 full‐time jobs in London and creates added value of over £1 billion and the London music business has net foreign earnings of over £400 million per annum.
The chapter concludes with some reflections on the implications of this research for music policy at both the national and city level. The statistical evidence demonstrates that classical music, a genre with only 10 per cent of the audience, continues to attract over 90 per cent of public subsidy. A similar imbalance in training of education of musicians means that the development of many young and talented non‐classical musicians is left to the vagaries of the market. 相似文献
While there is no universal logic of induction, the probabilitycalculus succeeds as a logic of induction in many contexts throughits use of several notions concerning inductive inference. Theyinclude Addition, through which low probabilities representdisbelief as opposed to ignorance; and Bayes property, whichcommits the calculus to a refute and rescale dynamicsfor incorporating new evidence. These notions are independentand it is urged that they be employed selectively accordingto needs of the problem at hand. It is shown that neither isadapted to inductive inference concerning some indeterministicsystems.
