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
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.

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members. 相似文献
This study presents a quantitative content analysis of the romantic expressions portrayed in the 12 Disney princess movies. The films were analyzed for presence of romantic expressions (ideals and challenges) and the character reactions to those expressions. Results indicated that romantic expressions are prevalent in these films, with idealization of other as the most common ideal expressed. The transitional era of films (i.e., princess movies released between 1989 and 1998) contained roughly the same number of ideals as the other eras of classic (i.e., movies released before 1989) and modern (i.e., movies released after 1998) combined. Further, ideals were three times more common than challenges in classic films, whereas ideals and challenges were expressed equally in transitional and modern films. In general, across all three eras, challenges were most commonly met with punishing and negative reactions, whereas ideals were most often rewarded. Finally, there were no sex differences in terms of ideal expressions, but male characters were the dominant pursuers in 9 of the 11 films that featured a romantic relationship. 相似文献
Children in public schools challenge people’s conceptions of them by talking about their spiritualities and spiritual practices. Based on a one-year multicultural feminist critical narrative inquiry, this article examines how Black and Latina/o first grade children co-researchers interview family members to think about their beliefs, encourage others, and to acquire more spiritual knowledge. I provide three counterstories in which children choose a mother, an older sister, and a younger brother to interview. These counterstories demonstrate children’s diverse literacies and spiritual practices, and families’ involvement in children’s lives. I discuss implications for educational practices in support of Black and Latina/o children and their families. I highlight ways pedagogical practices can be critiqued and transformed in order to better support children.Dr. Nadjwa E. L.
