图书馆服务质量测评的影响因素及控制研究   总被引：10，自引：0，他引：10  

钱佳平  刘兹恒 《中国图书馆学报》2006,32(1)

在图书馆服务质量测评中,指标体系与服务质量的相关度,调查对象的选取和抽样方式以及问卷设计和数据分析处理技术等问题,都有可能影响评估数据的可靠性和有效性。要使服务测评指标体系与服务质量高度相关,需从两个方面加以控制。首先,评价指标的建立和优化要符合以下原则:现实服务评估和前瞻性预测的有机结合;指标内涵的单义性和具体化;指标体系稳定性和动态优化的有机结合。此外,还要鼓励用户发表意见,作为补充的反馈优化机制。表3。参考文献9。  相似文献

基于粗糙集的决策规则可靠性评估方法     

李一强  吕宁 《大观周刊》2011,(18):123-124,113

粗糙集理论是处理不精确、不准确数据的有效方法，但是通过粗糙集方法获得的决策规则对于不完整的信息承统和随机数据也是不确定的。本文描述了一个用于决策规则的可靠性评价方法。该方法独立于任何专用引申规则方法，并且参数能够被调整以适应不同的信息系统。  相似文献   

A Framework for Policies and Practices to Improve Test Security Programs: Prevention,Detection, Investigation,and Resolution (PDIR)          下载免费PDF全文

Steve Ferrara 《Educational Measurement》2017,36(3):5-23

Test security is not an end in itself; it is important because we want to be able to make valid interpretations from test scores. In this article, I propose a framework for comprehensive test security systems: prevention, detection, investigation, and resolution. The article discusses threats to test security, roles and responsibilities, rigorous training for everyone involved in testing, and an evaluation of current practices in test security. I call on everyone responsible for testing programs—the Association of Test Publishers, Council of Chief State School Officers, National Council on Measurement in Education, U.S. Department of Education, and state assessment program managers, their vendors, and the research community—to collaborate on guidelines and practices for security violation prevention, detection, investigation, and resolution.  相似文献

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.  相似文献   

The impact of immediate test score reporting on university students' achievement emotions in the context of computer-based multiple-choice exams     

《Learning and Instruction》2017

Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.  相似文献   

Methodological Choices in the Content Analysis of Textbooks for Measuring Alignment With Standards          下载免费PDF全文

Morgan S. Polikoff  Nan Zhou  Shauna E. Campbell 《Educational Measurement》2015,34(3):10-17

With the recent adoption of the Common Core standards in many states, there is a need for quality information about textbook alignment to standards. While there are many existing content analysis procedures, these generally have little, if any, validity or reliability evidence. One exception is the Surveys of Enacted Curriculum (SEC), which has been widely used to analyze the alignment among standards, assessments, and teachers’ instruction. However, the SEC can be time‐consuming and expensive when used for this purpose. This study extends the SEC to the analysis of entire mathematics textbooks and investigates whether the results of SEC alignment analyses are affected if the content analysis procedure is simplified. The results indicate that analyzing only every fifth item produces nearly identical alignment results with no effect on the reliability of content analyses.  相似文献
