ISBN的不规范现象与图书馆的应对措施   总被引：4，自引：1，他引：4

ISBN与图书本来具有唯一性，但不少多卷书或丛书的总题名既有ISBN，各分卷(册)又有不同的ISBN，这是出版界对ISBN的滥用。图书馆在处理这类图书时，应根据不同的处理方式采用与正题名相对应的ISBN。  相似文献

高等院校分层发展刍议     

蔡延泉  吴海光 《煤炭高等教育》2006,24(5):61-63

当前在我国高等院校分层发展中凸现出不少问题,主要原因在于我国尚无公认合理的高校分层标准。从宏观层面分析,分层标准制定中有以下不可或缺的因素:师资水平和生源质量是高校分层的人力依据,教育设施、设备的优劣是高校分层的物力依据,教学、科研经费的多寡是高校分层的财力依据。在高校分层过程中,要强化社会评价体系和评价机制在高校分层中的角色扮演,淡化政府主管部门的地位和作用,注重高校自主定位的科学性。  相似文献   

The Issue of Range Restriction in Bookmark Standard Setting          下载免费PDF全文

Adam E. Wyse 《Educational Measurement》2015,34(2):47-54

This article uses data from a large‐scale assessment program to illustrate the potential issue of range restriction with the Bookmark method in the context of trying to set cut scores to closely align with a set of college and career readiness benchmarks. Analyses indicated that range restriction issues existed across different response probability (RP) values and item response theory (IRT) models if one were to apply the Bookmark procedure using intact test forms. Results also suggested that range restriction may still be present if one had access to additional data from an item bank. This demonstration critically highlights challenges that may exist in some practical applications of the Bookmark method due items not being designed to cover the full range of examinee abilities.  相似文献   

A Critical Look into the Beuk Standard-Setting Method     

Adam E. Wyse 《Educational Measurement》2020,39(1):52-60

One commonly used compromise standard-setting method is the Beuk (1984) method. A key assumption of the Beuk method is that the emphasis given to the pass rate and the percent correct ratings should be proportional to the extent that the panelists agree on their ratings. However, whether the slope of Beuk line reflects the emphasis that panelists believe should be assigned to the pass rate and the percentage correct ratings has not be fully tested. In this article, I evaluate this critical assumption of the Beuk method by asking panelists to assign importance weights to their percentage correct and pass rate judgments. I show that in several cases that the emphasis suggested by the Beuk slope is noticeably different from what one would expect and is inconsistent with importance weight ratings. I also suggest two ways that the importance weights can be used to calculate alternate cut scores, and I show that one of the ways of calculating cut scores using the importance weights leads to larger potential differences in cut score estimates. I suggest that practitioners should consider collecting importance weights when the Beuk method is used for determining cut scores.  相似文献
