粗糙集理论在情报分析指标权重确定中的应用   总被引：1，自引：0，他引：1  

周志远  沈固朝 《情报理论与实践》2012,35(9):61-65

情报分析中经常会遇到多指标综合评价问题,其中指标权重确定是关键。现有的主观赋值法因过度依赖专家经验而缺乏客观性,一些客观赋值法虽以客观数据分析为基础,但其结果解释性较差。文章引入一种基于粗糙集理论的权重确定方法。该方法不需要任何先验信息,即可完成权重计算,可使情报分析结果更加客观、有效。最后以我国企业海外并购风险评价为例阐释其应用。  相似文献   

高职公共选修课开设标准和评价机制的构建研究     

杨青 《扬州教育学院学报》2012,30(3):45-47

目前我国高职院校开设的公共选修课是整个高职课程体系设置和人才培养过程中的一个薄弱环节,在课程开设和评价方面存在诸多问题。要建立一套有效的课程开设标准和评价机制,必须遵循客观性评价和主观性评价相结合、定量评价与定性评价相结合、终结性评价和形成性评价相统一的原则,从课程、教学资源配置、学生选课三方面设置课程开设标准,从教师和学生两个角度构建评价机制,完善高职课程体系。  相似文献

Effect of Content Knowledge on Angoff‐Style Standard Setting Judgments     

Melissa J. Margolis  Janet Mee  Brian E. Clauser  Marcia Winward  Jerome C. Clauser 《Educational Measurement》2016,35(1):29-37

Evidence to support the credibility of standard setting procedures is a critical part of the validity argument for decisions made based on tests that are used for classification. One area in which there has been limited empirical study is the impact of standard setting judge selection on the resulting cut score. One important issue related to judge selection is whether the extent of judges’ content knowledge impacts their perceptions of the probability that a minimally proficient examinee will answer the item correctly. The present article reports on two studies conducted in the context of Angoff‐style standard setting for medical licensing examinations. In the first study, content experts answered and subsequently provided Angoff judgments for a set of test items. After accounting for perceived item difficulty and judge stringency, answering the item correctly accounted for a significant (and potentially important) impact on expert judgment. The second study examined whether providing the correct answer to the judges would result in a similar effect to that associated with knowing the correct answer. The results suggested that providing the correct answer did not impact judgments. These results have important implications for the validity of standard setting outcomes in general and on judge recruitment specifically.  相似文献   

Condensed Mastery Profile Method for Setting Standards for Diagnostic Assessment Systems          下载免费PDF全文

A. K. Clark  B. Nash  M. Karvonen  N. Kingston 《Educational Measurement》2017,36(4):5-15

The purpose of this study was to develop a standard‐setting method appropriate for use with a diagnostic assessment that produces profiles of student mastery rather than a single raw or scale score value. The condensed mastery profile method draws from established holistic standard‐setting methods to use rounds of range finding and pinpointing to specify cut points between performance levels. Panelists are convened to review profiles of mastery and specify cut points between performance levels based on the total number of skills mastered. Following panelist specification of cut points, a statistical method is implemented to smooth cut points over grades to decrease between‐grade variability. Procedural evidence, including convergence plots, standard errors of pinpointing ratings, and panelist feedback, suggest the condensed mastery profile method is a useful and technically sound approach for setting performance standards for diagnostic assessment systems.  相似文献   

The Impact of Examinee Performance Information on Judges’ Cut Scores in Modified Angoff Standard‐Setting Exercises     

Melissa J. Margolis  Brian E. Clauser 《Educational Measurement》2014,33(1):15-22

This research evaluated the impact of a common modification to Angoff standard‐setting exercises: the provision of examinee performance data. Data from 18 independent standard‐setting panels across three different medical licensing examinations were examined to investigate whether and how the provision of performance information impacted judgments and the resulting cut scores. Results varied by panel but in general indicated that both the variability among the panelists and the resulting cut scores were affected by the data. After the review of performance data, panelist variability generally decreased. In addition, for all panels and examinations pre‐ and post‐data cut scores were significantly different. Investigation of the practical significance of the findings indicated that nontrivial fail rate changes were associated with the cut score changes for a majority of standard‐setting exercises. This study is the first to provide a large‐scale, systematic evaluation of the impact of a common standard setting practice, and the results can provide practitioners with insight into how the practice influences panelist variability and resulting cut scores.  相似文献   

北京奥运会中美媒体议程设置比较研究     

曹荣芳  吴飞  吴新宇 《成都体育学院学报》2011,37(2)

运用文献资料、逻辑分析和个案研究等方法和调查数据,对北京奥运会申办成功以来至举办期间的中美主流媒体议程设置进行了梳理和比较研究.研究侧重探讨了隐含在北京奥运会中美议程设置层面后的媒体体制、意识形态、他塑等背景和中美媒体正负议程设置的客观环境,并通过分析找到了我国媒体议程设置和美媒的差异所在.认为提高我国各级官员和媒体工作者的媒介议程素养、他塑能力、媒体传播效果、借鉴美媒负面疏导理念应是后奥运时期我国媒体议程建设的重点内容之一.  相似文献
