Prediction assessments: Using video-based predictions to assess prospective teachers’ knowledge of students’ mathematical thinking     

Anderson Norton  Andrea McCloskey  Rick A. Hudson 《Journal of Mathematics Teacher Education》2011,14(4):305-325

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

The value of music in London     

Dave Laing  Norton York 《Cultural Trends》2000,10(38):1-34

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

Probability Disassembled     

Norton  John D. 《The British journal for the philosophy of science》2007,58(2):141-171

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.

Agricultural extension in South-Eastern Europe: Issues of transition and sustainability     

Lefter Daku  George W. Norton  Daniel B. Taylor  Eivis Qenani-Petrela 《The Journal of Agricultural Education and Extension》2013,19(1-4):49-61

Following the economic reforms in the early 90's, most of the south-eastern European countries (SEE) made efforts to establish agricultural extension services. However, a number of factors including tight governmental budgets, lack of experience, and the existence of vested interests have constrained the development of extension services. This paper examines the rationale for public funding of extension programs and evaluates the incentive structure for private and public provision of agricultural extension service in the SEE countries. It suggests a medium and long-term approach with a primary focus on institutional design. Two groups of factors that affect the private sector supply of extension are analyzed: (i) demand and supply-side factors that affect the profitability of the service and (ii) factors arising from the public-good nature of extension output, externalities, and moral hazards that affect the appropriation of returns of the service. The main conclusion is that the SEE countries should try to achieve a public-private extension balance by following a gradual approach toward privatization of the agricultural extension service. However, the paper advocates a continued important role for the public sector to correct for potential undesirable effects of private advisory services.  相似文献   

COMPARISON OF THE BECK DEPRESSION INVENTORY-II AND THE INVENTORY TO DIAGNOSE DEPRESSION: IMPLICATIONS FOR COMMUNITY COLLEGE COUNSELORS     

Stephen E. Craig  E. Douglas Norton 《Community College Journal of Research & Practice》2013,37(6):495-504

Community college counselors need to assess depressive symptoms in students and to differentiate depressive symptoms from anxiety symptoms to help them implement crisis intervention strategies. Two instruments available to the community college counselor are the Beck Depression Inventory-II (BDI-II) and the Inventory to Diagnose Depression (IDD). This article, which is based on the published literature, reports on and discusses the construct and discriminant validities of the BDI-II and IDD so that community college counselors may use them with knowledge of the strengths and weaknesses of each instrument. Although results should be interpreted with caution, both instruments are useful in measuring the presence or absence of depressive symptoms.  相似文献   

A Longitudinal View of the Liberal Arts Curriculum a Decade After Merger: A Multiple Case Study of Community Colleges in Connecticut,Kentucky, and Louisiana     

Ann Norton  Kristin Wilson 《Community College Journal of Research & Practice》2013,37(7):591-602

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   

Happily Ever After? A Content Analysis of Romantic Ideals in Disney Princess Films     

Veronica Hefner  Rachel-Jean Firchau  Katie Norton  Gabriella Shevel 《Communication Studies》2017,68(5):511-532

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
