In this paper, we discuss curricular implications of item banking and its practical value to teachers and students, and list a variety of working banks with their sources. We also review the psychometric basis of item banking, outline a family of computer programs for accomplishing banking, and give the equations necessary to build a bank. We conclude with a discussion of item quality control and examples of items that misfit because of miskeying, guessing, or carelessness. 相似文献

The debate about the proper relationship between the sciences and the humanities as formulated by C.P. Snow in his influential lecture, “The Two Cultures and the Scientific Revolution” and as rebutted by F.R. Leavis in a lecture entitled, “The Significance of Lord Snow” still goes on today. Its frames of reference, however, should be broadened from concentration on the lack of communication routes between the two cultures in question so as to deal with the problem of the lack of communication within given cultures and the rise of overlapping cultures such as that of social scientists. The debate, so far as universities are concerned, should be not so much one of science versus humanities but one of general versus specialized education with increased importance being given to the role and scope of continuing education. The university should be one place in society in which cultures communicate and converge and problems are solved critically and imaginatively so that graduates may emerge truly educated. 相似文献

本文认为用(δQ_P)/(dT)定义状态函数C_P的做法是欠妥的,未能揭示概念本质,不符合定义规则。但用偏导数(H/T)_P直接定义C_P并将C_P=(δQ_P)/(dT)作为等压热容的导出式是严密可行的。除可避免以往概念上的混淆外,重要的可使C_P三(H/T)_P的适用范围大大地扩大,所处理的问题直接明潦,具有较强的逻辑性和严密性,给教与学带来方便。 相似文献
