基于特征数据的开放式同行评议关键因素的实证分析

【目的】对影响开放式同行评议实践的相关因素进行实证研究,发掘开放式同行评议的关键影响因素。【方法】以Directory of Open Access Journals (DOAJ)中开放式同行评议期刊为研究对象,通过网络爬取相关数据。采用变量分类赋值的方式,对影响开放式同行评议的相关定性因素进行量化分析。采用多重对应分析图展示开放式同行评议相关影响因素及其不同类别的内在关联;采用最优尺度回归模型揭示相关影响因素对开放评议类型的影响程度。【结果】开放评议类型与评议专家身份的公开类别具有极密切的关联,评议专家身份对开放评议类型有显著正向影响,且重要性程度值非常高。【结论】评议专家身份是否公开成为开放式同行评议实践模式的关键影响因素,透明性同行评议是当前开放评议行之有效的实践模式。     

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

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.
