This book was released on 2008 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer adaptive testing (CAT) has grown both in research and implementation. Test construction and security issues, however, have led many to reconsider the merits of CAT. Multistage testing (MST) is an alternative adaptive test design that purportedly addresses CAT's shortcomings. Yet considerably less research has been conducted on MST. Also, most research in adaptive testing has been based on item response theory (IRT). Many tests now make use of testlets -- bundles of items administered together, often based on a common stimulus. The use of testlets violates local independence, a fundamental assumptions of IRT. Testlet response theory (TRT) is a relatively new measurement model designed to measure testlet-based tests. Few studies though have examined its use in testlet-based CAT and MST designs. This dissertation investigated the performance of testlet-based CATs and MSTs measured using the TRT model. The test designs compared included a CAT that is adaptive at the testlet level only (testlet-level CAT), a CAT that is adaptive at both the testlet and item levels (item-level CAT) and a MST design (MST). Test conditions manipulated included test length, item pool size, and examinee ability distribution. Examinee data were generated using TRT-calibrated item parameters based on data from a large-scale reading assessment. The three test designs were evaluated based on measurement effectiveness and exposure control properties. The study found that all three adaptive test designs yielded similar and good measurement accuracy. Overall, the item-level CAT produced better measurement precision, followed by the MST design. However, the MST and CAT designs yielded better measurement precision at different areas of the ability scale. All three test designs yielded acceptable exposure control properties at the testlet level. At the item level, the testlet-level CAT produced the best overall result. The item-level CAT had less than ideal pool utilization, but was able to meet its pre-specified maximum exposure control rate and maintain low item exposure rates. The MST had excellent pool utilization, but a higher percentage of items with high exposure rates. Skewing the underlying ability distribution also had a particularly notable negative effect on the exposure control properties of the MST.

This book was released on 2008 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-stage test (MST) design is an alternative design for the delivery of automated tests. While computerized adaptive tests (CAT) have dominated testing for the past three decades, increasing interest has been focused on the MST because it offers two advantages that CAT does not: Test sponsors and test developers can see an entire test before administration because it is pre-constructed from sets of modules of test items, and within a module examinees may skip forward and back through test items and make changes to previously answered items. Due to the dominance of CAT, little research has been devoted to differing MST designs with regard to the number of items per stage and routing rules that direct the selection of the next module after a previous module has been completed. This research used simulated response data for a large national test and the generalized partial credit model to compare a CAT to one of three MST designs that had either decreasing numbers of items per stage, increasing number of items per stage, or the same number of items per stage, and one of three routing rules, maximum information, fixed [theta], or number-right routing. As anticipated, CAT had the best performance with respect to estimating proficiency and item pool use. Among the MSTs, the MST with increasing numbers of items per stage performed the best with respect to estimating proficiency, followed by the MST with decreasing number of items per stage, and equal numbers of items per stage. By routing rule, maximum information performed the best and number-right routing performed the worst. Only one panel was constructed per MST design, so only limited comparisons of item pool use could be made. Although the MST designs did not perform as well as CAT, the differences in estimating proficiency were not large, implying that the MST design is a viable alternative to CAT.

Book Synopsis Computerized Adaptive and Multistage Testing with R by : David Magis
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.

Book Synopsis Innovations in Computerized Assessment by : Fritz Drasgow
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?
Book Synopsis Computers and Their Impact on State Assessments by : Robert W. Lissitz
Download or read book Computers and Their Impact on State Assessments written by Robert W. Lissitz and published by IAP. This book was released on 2012-05-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Race To The Top program strongly advocates the use of computer technology in assessments. It dramatically promotes computer-based testing, linear or adaptive, in K-12 state assessment programs. Moreover, assessment requirements driven by this federal initiative exponentially increase the complexity in assessment design and test development. This book provides readers with a review of the history and basics of computer-based tests. It also offers a macro perspective for designing such assessment systems in the K-12 setting as well as a micro perspective on new challenges such as innovative items, scoring of such items, cognitive diagnosis, and vertical scaling for growth modeling and value added approaches to assessment. The editors’ goal is to provide readers with necessary information to create a smarter computer-based testing system by following the advice and experience of experts from education as well as other industries. This book is based on a conference (http://marces.org/workshop.htm) held by the Maryland Assessment Research Center for Education Success. It presents multiple perspectives including test vendors and state departments of education, in designing and implementing a computer-based test in the K-12 setting. The design and implementation of such a system requires deliberate planning and thorough considerations. The advice and experiences presented in this book serve as a guide to practitioners and as a good source of information for quality control. The technical issues discussed in this book are relatively new and unique to K-12 large-scale computer-based testing programs, especially due to the recent federal policy. Several chapters provide possible solutions to psychometricians dealing with the technical challenges related to innovative items, cognitive diagnosis, and growth modeling in computer-based linear or adaptive tests in the K-12 setting.

Book Synopsis Advancing Methodologies to Support Both Summative and Formative Assessments by : Ying Cheng
Download or read book Advancing Methodologies to Support Both Summative and Formative Assessments written by Ying Cheng and published by IAP. This book was released on 2014-03-01 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past thirty years, student assessment has become an increasingly important component of public education. A variety of methodologies in testing have been developed to obtain and interpret the wealth of assessment outcomes. As assessment goals are getting increasingly multifaceted, new testing methodologies are called for to provide more accessible and reliable information on more complex constructs or processes, such as students' critical thinking and problem-solving skills. Testing methodologies are needed to extract information from assessments on such complicated skills, in order to advise teachers about certain areas of students that need intervention. It is even a bigger challenge, and a vital mission of today’s large-scale assessments, to gain such information from testing data in an efficient manner. For example PARCC and Smarter Balanced Assessments consortia are both striving to offer formative assessments through individualized, tailored testing. The book provides state-of-the-art coverage on new methodologies to support tradit ional summative assessment, and more importantly, for emerging formative assessments.

Download or read book An Investigation on Computer-adaptive Multistage Testing Panels for Multidimensional Assessment written by Xinrui Wang and published by . This book was released on 2013 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The computer-adaptive multistage testing (ca-MST) has been developed as an alternative to computerized adaptive testing (CAT), and been increasingly adopted in large-scale assessments. Current research and practice only focus on ca-MST panels for credentialing purposes. The ca-MST test mode, therefore, is designed to gauge a single scale. The present study is the first step to investigate ca-MST panels for diagnostic purposes, which involve the assessment of multiple attributes in the same test. This study employed computer simulation to compare multidimensional ca-MST panels and their unidimensional counterparts, and to explore the factors that affect the accuracy and efficiency of multidimensional ca-MST. Nine multidimensional ca-MST panel designs - which differed in configuration and test length - were simulated under varied attribute correlation scenarios. In addition, item pools with different qualities were studied to suggest appropriate item bank design. The comparison between the multidimensional ca-MST and a sequential of unidimensional ca-MST suggested that when attributes correlated moderate to high, employing a multidimensional ca-MST provided more accurate and efficient scoring decisions than several unidimensional ca-MST with IRT scoring. However, a multidimensional ca-MST did not perform better than its unidimensional counterpart with MIRT scoring. Nevertheless, multidimensional panels are still promising for diagnostic purposes given practical considerations. The investigation on multidimensional ca-MST design indicated the following: Higher attribute correlation was associated with better scoring decision because more information carried by a correlation matrix was available for estimation. This held true across all item pool conditions. An optimal item pool would be the one that was discriminative, appropriately located and specifically designed for a configuration. The accuracy and efficiency of a multidimensional ca-MST panel would be diminished if its item pool was too easy, or not informative. According to the results, the 1-2-3 configuration design was most promising. In terms of test length, an appropriate decision would largely depend on the attribute correlation and the item pool characteristics."--Abstract from author supplied metadata.
