Validating Student Score Inferences With Person‐Fit Statistic and Verbal Reports: A Person‐Fit Study for Cognitive Diagnostic Assessment     

Ying Cui  Mary Roduta Roberts 《Educational Measurement》2013,32(1):34-42

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way.  相似文献

科技服务业个人-工作动态契合与企业创新绩效的关系研究     

王林雪  李昆鹏  邵芳 《科技管理研究》2015,(6):162-167

基于需要-满足理论与社会认知理论,针对科技服务业企业,从供给-需求契合,要求-能力契合,自我概念-工作契合三个方面研究个人-工作动态契合与企业创新绩效的关系。将心理授权作为部分中介变量,验证发现,个人-工作动态契合与企业创新绩效之间存在正向影响,供给-需求契合与心理授权之间不存在显著正向关系,要求-能力契合,自我概念-工作契合与心理授权之间存在显著正向关系。  相似文献   

组织吸引力的影响因素元分析：基于过去25年研究的回顾     

翁清雄  吴松 《预测》2015,(1)

本文在对过去25年组织吸引力相关研究回顾的基础上,采用元分析的方法从工作的功能性特征、象征性特征,以及P-J匹配、P-O匹配等方面梳理和验证了组织吸引力的主要影响因素,探索和检验了上述因素与组织吸引力之间关系的潜在调节变量。元分析结果表明：功能性特征与组织吸引力显著相关,其中晋升机会(r=0.343)、薪资(r=0.327)与组织吸引力的相关性最高;象征性特征中,除强壮外,其他工作特征与组织吸引力均显著相关;P-O匹配(r=0.455)和P-J匹配(r=0.366)与组织吸引力之间的相关性较强;性别的调节作用显著,而研究对象和年龄的调节作用均不显著。研究还探讨了组织吸引力的未来研究方向及管理应用。  相似文献

Assessing the Sensitivity of Weighted Least Squares Model Fit Indexes to Local Dependence in Item Response Theory Models     

Anne Corinne Huggins-Manley  HyunSuk Han 《Structural equation modeling》2017,24(3):331-340

Given the relationships of item response theory (IRT) models to confirmatory factor analysis (CFA) models, IRT model misspecifications might be detectable through model fit indexes commonly used in categorical CFA. The purpose of this study is to investigate the sensitivity of weighted least squares with adjusted means and variance (WLSMV)-based root mean square error of approximation, comparative fit index, and Tucker–Lewis Index model fit indexes to IRT models that are misspecified due to local dependence (LD). It was found that WLSMV-based fit indexes have some functional relationships to parameter estimate bias in 2-parameter logistic models caused by violations of LD. Continued exploration into these functional relationships and development of LD-detection methods based on such relationships could hold much promise for providing IRT practitioners with global information on violations of local independence.  相似文献   

谦逊领导对个人—团队匹配的影响及其作用机制研究     

蔡地  刘佳  马金鹏 《研究与发展管理》2019,31(3):38-46

综合社会学习理论和最佳区分性理论两种视角，引入团队成员交换为中介变量，检验谦逊领导对个人—团队匹配的作用机制。基于对52个项目团队277名成员的问卷调查，研究发现：谦逊领导对员工团队成员交换有着积极影响，团队成员交换对个人—团队匹配（一致性匹配、互补性匹配）有着积极影响；团队成员交换在谦逊领导与个人—团队匹配（一致性匹配、互补性匹配）之间起中介作用。研究结果丰富了谦逊领导、团队成员交换、个人—团队匹配领域的研究，并对组织管理实践有一定启示作用。  相似文献   

Teacher-working-environment fit as a framework for burnout experienced by Finnish teachers     

Kirsi Pyhältö  Janne Pietarinen 《Teaching and Teacher Education》2011,27(7):1101-1110

The purpose of this study was to explore the kinds of episodes that challenge comprehensive school teachers’ occupational well-being and cause burnout and how teachers perceive the relationship between themselves and their working environment in these episodes. Altogether, a selected group of 68 primary and secondary school teachers were interviewed. The narratives of burdening episodes were identified and analysed from the qualitative data. The results suggested that teachers’ working environment provides multiple contexts for burnout. Sources for teacher burnout varied between the working contexts provided by the single school. Moreover, the results showed that there was heterogeneity in the quality of the teacher-working-environment fit reported by the teachers while facing burdening situations or series of events in their work.  相似文献   

计量经济学课程教学应注意的三个问题     

欧元明 《科教文汇》2011,(34):59-59,141

计量经济学是经济学类专业中最受重视的几门课程之一。笔者在教学活动中发现,尽管很多学生为学好这门课程花了大量的精力,但在部分问题的理解上还是存在偏误。笔者经过归纳总结,认为在教学过程中不应忽视三个知识点的讲解,即线性与拟合优度的含义、经典假设的作用。  相似文献
