Evaluating the Comparability of Paper‐ and Computer‐Based Science Tests Across Sex and SES Subgroups     

Jennifer Randall  Stephen Sireci  Xueming Li  Leah Kaira 《Educational Measurement》2012,31(4):2-12

As access and reliance on technology continue to increase, so does the use of computerized testing for admissions, licensure/certification, and accountability exams. Nonetheless, full computer‐based test (CBT) implementation can be difficult due to limited resources. As a result, some testing programs offer both CBT and paper‐based test (PBT) administration formats. In such situations, evidence that scores obtained from different formats are comparable must be gathered. In this study, we illustrate how contemporary statistical methods can be used to provide evidence regarding the comparability of CBT and PBT scores at the total test score and item levels. Specifically, we looked at the invariance of test structure and item functioning across test administration mode across subgroups of students defined by SES and sex. Multiple replications of both confirmatory factor analysis and Rasch differential item functioning analyses were used to assess invariance at the factorial and item levels. Results revealed a unidimensional construct with moderate statistical support for strong factorial‐level invariance across SES subgroups, and moderate support of invariance across sex. Issues involved in applying these analyses to future evaluations of the comparability of scores from different versions of a test are discussed.  相似文献

Application of the Levenshtein Distance Metric for the Construction of Longitudinal Data Files     

Harold C. Doran  Paul B. Van Wamelen 《Educational Measurement》2010,29(2):13-23

The analysis of longitudinal data in education is becoming more prevalent given the nature of testing systems constructed for No Child Left Behind Act (NCLB). However, constructing the longitudinal data files remains a significant challenge. Students move into new schools, but in many cases the unique identifiers (ID) that should remain constant for each student change. As a result, different students frequently share the same ID, and merging records for an ID that is erroneously assigned to different students clearly becomes problematic. In small data sets, quality assurance of the merge can proceed through human reviews of the data to ensure all merged records are properly joined. However, in data sets with hundreds of thousands of cases, quality assurance via human review is impossible. While the record linkage literature has many applications in other disciplines, the educational measurement literature lacks details of formal protocols that can be used for quality assurance procedures for longitudinal data files. This article presents an empirical quality assurance procedure that may be used to verify the integrity of the merges performed for longitudinal analysis. We also discuss possible extensions that would permit merges to occur even when unique identifiers are not available.  相似文献

Researching educational policy and change in ‘new times’: using critical discourse analysis     

Sandra Taylor 《教育政策杂志》2013,28(4):433-451

A number of writers have drawn attention to the increasing importance of language in social life in ‘new times’ and Fairclough has referred to ‘discourse driven’ social change. These conditions have led to an increase in the use of various forms of discourse analysis in policy analysis. This paper explores the possibilities of using Critical Discourse Analysis (CDA) in critical policy research in education, drawing on a larger research project which is investigating the equity implications of Education Queensland’s reform agenda. It is argued that, in the context of new times, CDA is of particular value in documenting multiple and competing discourses in policy texts, in highlighting marginalized and hybrid discourses, and in documenting discursive shifts in policy implementation processes. The last part of the paper discusses how such research might be used by policy activists inside and outside education department bureaucracies to further social democratic goals.  相似文献
