Available in PDF, EPUB and Kindle. Book excerpt: The arrival of the computer in educational and psychological testing has led to the current popularity of adaptive testing---a testing format in which the computer uses statistical information about the test items to automatically adapt their selection to a real-time update of the test taker’s ability estimate. This book covers such key features of adaptive testing as item selection and ability estimation, adaptive testing with multidimensional abilities, sequencing adaptive test batteries, multistage adaptive testing, item-pool design and maintenance, estimation of item and item-family parameters, item and person fit, as well as adaptive mastery and classification testing. It also shows how these features are used in the daily operations of several large-scale adaptive testing programs.

Download or read book Computerized Adaptive and Multistage Testing with R written by David Magis and published by Springer. This book was released on 2017-11-23 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this guide and manual is to provide a practical and brief overview of the theory on computerized adaptive testing (CAT) and multistage testing (MST) and to illustrate the methodologies and applications using R open source language and several data examples. Implementation relies on the R packages catR and mstR that have been already or are being developed by the first author (with the team) and that include some of the newest research algorithms on the topic. The book covers many topics along with the R-code: the basics of R, theoretical overview of CAT and MST, CAT designs, CAT assembly methodologies, CAT simulations, catR package, CAT applications, MST designs, IRT-based MST methodologies, tree-based MST methodologies, mstR package, and MST applications. CAT has been used in many large-scale assessments over recent decades, and MST has become very popular in recent years. R open source language also has become one of the most useful tools for applications in almost all fields, including business and education. Though very useful and popular, R is a difficult language to learn, with a steep learning curve. Given the obvious need for but with the complex implementation of CAT and MST, it is very difficult for users to simulate or implement CAT and MST. Until this manual, there has been no book for users to design and use CAT and MST easily and without expense; i.e., by using the free R software. All examples and illustrations are generated using predefined scripts in R language, available for free download from the book's website.

Download or read book Item Selection Methods in Polytomous Computerized Adaptive Testing written by Usama S. Ali and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the rapid advancement of computer technology, the importance of administering adaptive tests with polytomous items is in great need. With regard to the applicability of adaptive testing using polytomous IRT models, adaptive testing can use polytomous items of either rating scales, or in some testing situations of multiple choice. Additionally, the availability of computerized polytomous scoring of open-ended items enhances such applicability. This need promotes the research in polytomous adaptive testing (PAT). This dissertation is an e ort to focus on item selection methods, as a major component, in polytomous computerized adaptive testing. So, it consists of ve chapters that cover the following: Chapter 1 focuses on a thorough introduction to the item response theory (IRT) models and adaptive testing related to polytomous items. Such an important overview and introduction to basic concepts in test theory and mathematical models for polytomous items is needed for the ow of consequent chapters. Chapter 2 is devoted to the development of a central location index (LI) to uniquely represent the polytomous item with a scale value parameter using most commonly used polytomous models. The motivation and rationale to search for a central or an overall location parameter is twofold: a) the confusion of multiple and di erent parameterizations for a polytomous item even for the same model, and b) the unavailability of such single location parameter block the usage of certain item selection methods in adaptive testing. Two approaches are used to derive the proposed LIs, one is based on the item category response functions (ICRFs) and the other is based on the polytomous item response function (IRF). As a result, four LIs are proposed. Chapter 3 is particularly assigned to development of an item selection method based on the developed location index and primarily assess its performance in the PAT context relative to existing methods. This method belongs to the non-information based item selection methods and we referred it as Matching-LI method. The results support that this proposed method is promising and is capable to produce accurate ability estimates and successfully manage the item pool usage. Chapter 4 introduces new item selection methods taking in consideration the previous chapter's results. The new methods are the hybrid, stage-based information, polytomous a-strati cation methods. The first two methods try to merge more than one criterion for selecting items of each PAT (e.g., the hybrid method merges both the Matching-LI and maximum information (MI) methods). The last method uses Matching-LI method within each stratum. Chapter 5 provides discussion, conclusions, and limitations and future research directions with respect to important components of an adaptive testing program (i.e., item selection methods, item response models, item banks, and trait versus attribute estimation).

Available in PDF, EPUB and Kindle. Book excerpt: This symposium consisted of four papers and the comments of two discussants. C. David Vale. Problem: Strategies of Branching through an Item Pool. This paper describes a variety of strategies for adapting tests to the trait level of each individual on the basis of the testee's responses to previously administered items. Based on data from computer simulations, the various strategies are compared. James R. McBride. Problem: Scoring Adaptive Tests. Several approaches to scoring adaptive tests are described. James B. Sympson. Problem: Evaluating the Results of Adaptive Testing. Six component elements of a testing procedure are described; it is suggested that proper evaluation of a testing procedure should be based on consideration of these elements as separable components. Nancy E. Betz. Prospects: New Types of Information and Psychological Implications. Several types of new information available from computerized adaptive measurement are described. Comments by the discussants, Robert L. Linn of the University of Illinois and R. Darrell Bock of the University of Chicago, include a discussion of some of the limitations of the research presented, some differing interpretations, and suggestions for future research in adaptive testing.
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?

Download or read book A Guide to Computer Adaptive Testing Systems written by Tim Davey and published by . This book was released on 2011 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some brand names are used generically to describe an entire class of products that perform the same function. "Kleenex," "Xerox," "Thermos," and "Band-Aid" are good examples. The term "computerized adaptive testing" (CAT) is similar in that it is often applied uniformly across a diverse family of testing methods. Although the various members of this family share similar goals and employ similar means, they differ in important ways that can significantly impact how tests perform when delivered. This guide is intended to provide those responsible for procuring CAT systems with questions they can use to tease out differences across competing CAT delivery systems, and so make better-informed decisions. The scope of this guide is largely limited to differences across systems that can affect the quality, comparability, and usefulness of the test scores that a system produces. The substance of what is measured (the format and nature of the test questions) and test delivery issues (testing sites and test presentation software and hardware) will be considered only to the extent that they directly impact score properties. This guide is organized around the elements common to nearly all varieties of adaptive testing. To orient the reader to this framework, the guide begins with a brief introduction to adaptive testing methods and the sometimes arcane vocabulary that has grown up around those methods. Summary workbook is appended. (Contains 2 figures and 2 footnotes.).
