This book was released on 2008 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test security has been a concern for computerized adaptive tests (CAT) due to the nature of continuous testing. This concern becomes unprecedentedly severe with increasingly easy access to the World-Wide-Web where some examinees post on the internet their recollections of items they are administered, leaving future examinees with opportunities to get their scores inflated by having pre-knowledge of the items that appear in their tests. This study investigated, given some items in the item pool are disclosed, which item exposure control procedure results in minimum negative effect on ability estimate. The disclosed items in this study are defined as items released to the public or intentionally memorized by the test-takers and shared with future examinees and items to which examinees can respond correctly. The results from both simulation and statistical hypothesis testing are in consistent with Schnipke & Scrams (1999) in terms that the presence of disclosed items can inflate the final ability estimates in the context of CATs by an unacceptably high degree, especially for the low-ability examinees. Among all item exposure procedures under study, the a-stratified test with b-blocking, i.e., a design that stratifies the item pool but takes care of the relationship between item difficulty and discrimination parameters, performs the best. (Contains 18 tables, 3 figures, and 4 footnotes.).

This book was released on 2011 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability estimation procedure is one of the most important components in a computerized adaptive testing (CAT) system. Currently, all CATs that provide K-12 student scores are based on the item response theory (IRT) model(s); while such application directly violates the assumption of independent sample of a person in IRT models because ability estimation is mostly based on cluster (or correlated) educational data in which students usually are clustered in certain groups or settings (classrooms or schools). The consequences of such violations are commonly ignored. The purpose of this study is to investigate the effect of ignoring hierarchical data structures of students sample on the accuracy of ability estimation by using a regular Rasch model. Results show that ICCs have not only statistically significant effect on the accuracy of a person's ability estimation, but also large effect sizes. (Contains 13 tables and 7 figures.).

Download or read book Innovations in Computerized Assessment written by Fritz Drasgow and published by Psychology Press. This book was released on 1999-03-01 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computerized assessment offers many opportunities for innovations in measurement. In contrast to static paper-and-pencil instruments, computerized assessment can capitalize on the dynamic capabilities of the computer. For example, the difficulty of administered items can be adopted to the ability of the examinee, thus eliminating items that are too hard or too easy. Multimedia computers provide the opportunity to revolutionize assessment. Stereo sound, animation, and full-motion video can be incorporated into assessment tools and aid in the measurement of individual differences ranging from musical skills to interpersonal abilities. Innovations in Computerized Assessment presents the experiences of leading researchers in computerized assessment. The book places particular emphasis on the dilemmas that were faced by the researchers. Questions addressed include: * What problems did they confront? * What were the pros and cons of various options? * How were dilemmas resolved? * Were the solutions good ones?

Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license.​​ This book describes the extensive contributions made toward the advancement of human assessment by scientists from one of the world’s leading research institutions, Educational Testing Service. The book’s four major sections detail research and development in measurement and statistics, education policy analysis and evaluation, scientific psychology, and validity. Many of the developments presented have become de-facto standards in educational and psychological measurement, including in item response theory (IRT), linking and equating, differential item functioning (DIF), and educational surveys like the National Assessment of Educational Progress (NAEP), the Programme of international Student Assessment (PISA), the Progress of International Reading Literacy Study (PIRLS) and the Trends in Mathematics and Science Study (TIMSS). In addition to its comprehensive coverage of contributions to the theory and methodology of educational and psychological measurement and statistics, the book gives significant attention to ETS work in cognitive, personality, developmental, and social psychology, and to education policy analysis and program evaluation. The chapter authors are long-standing experts who provide broad coverage and thoughtful insights that build upon decades of experience in research and best practices for measurement, evaluation, scientific psychology, and education policy analysis. Opening with a chapter on the genesis of ETS and closing with a synthesis of the enormously diverse set of contributions made over its 70-year history, the book is a useful resource for all interested in the improvement of human assessment.

Download or read book Self directed Learning Oriented Assessments in the Asia Pacific written by Magdalena Mo Ching Mok and published by Springer Science & Business Media. This book was released on 2012-10-09 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Asia-Pacific region needs to maximize the benefits of education to enable it to compete in an economic future dominated by innovation, in which assessing student progress must be an empowering rather than delimiting factor. This detailed exposition of the theoretical basis and application tools of self-directed learning-oriented assessment (SLOA) reflects the very latest research championed by the Assessment Research Centre at The Hong Kong Institute of Education. Featuring a range of relevant case studies, it explores the varied theoretical issues related to SLOA and offers an integrated view of the system fully in line with the constructivist paradigm of learning which advocates formative rather than summative assessment. Many of the initiatives outlined here are firsts in the region. SLOA is already being applied in many schools with links to the ARC. It is an approach to assessment that acknowledges the centrality of self-directed learning and which positions assessment as a tool to enable and enhance self-directed learning. It draws on several theories of learning and assessment, including the constructivist notion that learning is best achieved when students take ownership of their educational process, setting their own goals and monitoring their own progress towards those goals. SLOA has been the research and service approach of the ARC since 2005. In the intervening years the centre has developed a number of tools to facilitate SLOA learning and assessment, including vertical ability scales, teacher-friendly computer software and packages for self-directed learning.

Download or read book Integrating Timing Considerations to Improve Testing Practices written by Melissa J. Margolis and published by Routledge. This book was released on 2020-06-03 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating Timing Considerations to Improve Testing Practices synthesizes a wealth of theory and research on time issues in assessment into actionable advice for test development, administration, and scoring. One of the major advantages of computer-based testing is the capability to passively record test-taking metadata—including how examinees use time and how time affects testing outcomes. This has opened many questions for testing administrators. Is there a trade-off between speed and accuracy in test taking? What considerations should influence equitable decisions about extended-time accommodations? How can test administrators use timing data to balance the costs and resulting validity of tests administered at commercial testing centers? In this comprehensive volume, experts in the field discuss the impact of timing considerations, constraints, and policies on valid score interpretations; administrative accommodations, test construction, and examinees’ experiences and behaviors; and how to implement the findings into practice. These 12 chapters provide invaluable resources for testing professionals to better understand the inextricable links between effective time allocation and the purposes of high-stakes testing.

Download or read book Fairness Issues in Educational Assessment written by Hossein Karami and published by Routledge. This book was released on 2018-02-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fairness and ethicality have been at the center of the debates on the appropriate use of educational tests since the 1960s. Particularly in high-stakes contexts, it is clear that fairness should be a major concern to both the test developers, and to those being tested, given that the fairness of a test is so intertwined with its validity. Fairness Issues in Educational Assessment aims to shed more light on the issue and bring to sight some of the ways in which test fairness can be addressed. The contributions, written by some of the most prominent figures in educational assessment, address both theoretical and practical aspects of test fairness. The wealth of ideas presented here will be valuable to novice researchers and help them appreciate both the joy and complexity of conducting fair educational measurement. This book was originally published as a special issue of Educational Research and Evaluation.
