Computerized Adaptive Testing: From Concept to Implementation de David J. Weiss

Computerized Adaptive Testing: From Concept to Implementation

Autor David J. Weiss, Alper Sahin
en Limba Engleză Hardback – 15 iul 2024

Bazându-ne pe documentația furnizată de editura Guilford Publications, putem afirma că acest volum reprezintă un ghid metodologic esențial pentru înțelegerea și aplicarea testării adaptative computerizate (CAT). Notăm cu interes abordarea pragmatică a autorilor, care reușesc să transforme un subiect tehnic complex într-un parcurs structurat de tip „how-to”, destinat atât cercetătorilor, cât și practicienilor din psihometrie și certificare profesională.

Remarcăm organizarea riguroasă a materialului în două părți distincte. Prima secțiune fundamentează necesitatea CAT, explorând tranziția istorică de la testele Binet la modelele moderne bazate pe Teoria Răspunsului la Itemi (IRT). Cuprinsul indică o progresie logică, de la funcțiile de răspuns pentru itemi dihotomici și politomici, până la estimarea parametrilor de informație. A doua parte a lucrării se concentrează pe aspectele operaționale, oferind soluții concrete pentru fezabilitate, planificare și utilizarea software-ului dedicat. Spre deosebire de alte lucrări colective, acest volum beneficiază de o voce editorială unitară și de o perspectivă coerentă asupra întregului flux de lucru.

În contextul operei autorului, Computerized Adaptive Testing completează cercetările anterioare ale lui David J. Weiss, precum Research for Practical Issues and Solutions in Computerized Multistage Testing. Dacă lucrarea menționată anterior se focaliza pe testarea multistadiu (MST), volumul de față revine la bazele fundamentale ale adaptivității în timp real, oferind un spectru mai larg de aplicații, inclusiv în zona clinică și a raportărilor pacienților. Ca alternativă la Elements of Adaptive Testing de Wim J. van der Linden pentru cursurile de psihometrie, volumul lui Weiss are avantajul de a pune un accent sporit pe implementarea practică și pe resursele software imediat utilizabile, fiind mai puțin abstract și mai orientat către mediul profesional.

De ce să citești această carte

Această resursă este recomandată specialiștilor în testare educațională și psihologică care doresc să implementeze sisteme de evaluare eficiente. Cititorul câștigă o înțelegere profundă a IRT și a logisticii CAT, beneficiind de expertiza unui pionier în domeniu. Este un instrument indispensabil pentru transformarea testelor clasice în evaluări dinamice, personalizate pentru fiecare respondent în timp real, optimizând astfel precizia măsurării.

Despre autor

David J. Weiss este o figură centrală în psihometria modernă, recunoscut ca pionier în dezvoltarea testării adaptative computerizate. Cariera sa s-a concentrat pe aplicarea metodelor cantitative în psihologie și educație, contribuind semnificativ la evoluția Teoriei Răspunsului la Itemi (IRT). Alături de Alper Șahin, acesta continuă să rafineze metodologiile de măsurare a diferențelor individuale. Weiss a publicat lucrări fundamentale care tratează atât analiza varianței, cât și soluții practice pentru testarea multistadiu, fiind un reper academic pentru cercetătorii din întreaga lume.

Descriere scurtă

Used worldwide in assessment and professional certification contexts, computerized adaptive testing (CAT) offers a powerful means to measure individual differences or make classifications. This authoritative work from CAT pioneer David J. Weiss and Alper Şahin provides a complete how-to guide for planning and implementing an effective CAT to create a test unique to each person in real time. The book reviews the history of CAT and the basics of item response theory used in CAT. It walks the reader through developing an item bank, pretesting and linking items, selecting required CAT options, and using simulations to design a CAT. Available software for CAT delivery is described, including links to free and commercial options. Engaging multidisciplinary examples illustrate applications of CAT for measuring ability, achievement, proficiency, personality, attitudes, perceptions, patients’ reports of their symptoms, and academic or clinical progress.

Recenzii

"This comprehensive book on CAT is unique in being an authored work with a coherent style and perspective. It covers all aspects of using CAT, including the development of item banks and operational systems along with the technical details of item calibration, proficiency estimation, and practical requirements, such as exposure control and content balancing. Also included is a historical overview of the development of the concepts underlying CAT. Written at an accessible level, the book does not require a strong background in psychometrics. It is an excellent resource for anyone with administrative responsibility for a CAT system, or for courses in applied measurement."--Mark Reckase, PhD, University Distinguished Professor Emeritus, College of Education, Michigan State University

"This book is great--it is the most easy-to-understand material on CAT I have read. It covers a wide range of research, from the early days of CAT to today. I recommend this book to any student who is interested in CAT, as well as anyone trying to develop a CAT program."--T. Chris Oshima, PhD, Department of Educational Policy Studies, Georgia State University

"This book meets a need in the measurement field for a comprehensive introductory presentation of CAT. It covers the basics in an accessible way, while also making clear the range of applications and contexts in which the basic CAT approach can be extended, as well as areas in need of future research."--Daniel M. Bolt, PhD, Department of Educational Psychology, University of Wisconsin–Madison

"Weiss has been involved with CAT from the beginning--he even gave the process its name. Reading this incredibly detailed, practical guide is like having Weiss as a consultant. He offers step-by-step advice on the development and implementation of a CAT system, based largely on his experience, his own research, and that of his students. This book is an invaluable resource for testing and measurement professionals who are considering or implementing a CAT system, as well as graduate students in training."--David Thissen, PhD, Department of Psychology and Neuroscience (Emeritus), University of North Carolina at Chapel Hill-

David J. Weiss, PhD, is Professor of Psychology at the University of Minnesota. Widely regarded as the father of computerized adaptive testing (CAT), he began his CAT research and founded the Quantitative and Psychometric Methods program at the University of Minnesota in 1970. His subsequent research provided the basis for the development of the CAT version of the Armed Services Vocational Aptitude Battery and a variety of other CAT implementations, including in education, nursing licensure, and personality measurement. Dr. Weiss has been active in CAT research continuously and has trained many leading CAT researchers and implementers. He was the founding editor of the journal Applied Psychological Measurement, and is co-founder and permanent President Emeritus of the International Association for Computerized Adaptive Testing (IACAT). He was the founding editor of IACAT’s official journal, the Journal of Computerized Adaptive Testing. Dr. Weiss also co-founded Assessment Systems Corporation and the Insurance Testing Corporation. A Fellow of the American Educational Research Association (AERA) and the American Psychological Association, he is a recipient of the Bradley Hanson Award for Contributions to Educational Measurement from the National Council on Measurement in Education and the Award for Significant Contribution to Educational Measurement and Research Methodology from Division D (Measurement and Research Methodologies) of the AERA.
