Argument Based Validation In Testing And Assessment

Carol A. Chapelle shows readers how to design validation research for tests of human capacities and performance. Any test that is used to make decisions about people or programs should have undergone extensive research to demonstrate that the scores are actually appropriate for their intended purpose. Argument-Based Validation in Testing and Assessment is intended to help close the gap between theory and practice, by introducing, explaining, and demonstrating how test developers can formulate the overall design for their validation research from an argument-based perspective.

With examples of validation studies, this book demonstrates how to design research investigating the validity of language tests.

Over the years, various approaches to validation have emerged in psychological and educational assessment research, which can be classified into traditional approaches and modern approaches. Traditional approaches view validity as a multicomponential concept including, for example, content, construct, and predictive validity, while modern approaches conceptualize it as a unitary concept evaluated through argumentation. Drawing on the modern approach, this book builds a validity argument for an International English Language Testing System (IELTS) listening test sample. The book provides some insights into the listening sub-skills that the test engages, the psychometric dimensionality of the test, variables that predict item difficulty parameters, bias across age, nationality, test experience, and gender, as well as predictive-referenced evidence of validity. A variety of techniques including the Rasch model and structural equation modelling are used to answer the research questions and to build a validity argument framework; this argument organizes the thematically related findings into a coherent treatment of the validity of the listening test. The book presents the first treatment of validity argument and related analytical tools in one volume and maps the psychometric/statistical analysis tools onto the validity argument framework. It also provides an extensive literature review of listening comprehension, validation, and psychometric modeling and proposes both methods for developing and validating self-assessment instruments and novel approaches to improving the quality of language assessments.

Validity is the hallmark of quality for educational and psychological measurement. But what does quality mean in this context? And to what, exactly, does the concept of validity apply? These apparently innocuous questions parachute the unwary inquirer into a minefield of tricky ideas. This book guides you through this minefield, investigating how the concept of validity has evolved from the nineteenth century to the present day. Communicating complicated concepts straightforwardly, the authors answer questions like: What does ′validity′ mean? What does it mean to ′validate′? How many different kinds of validity are there? When does validation begin and end? Is reliability a part of validity, or distinct from it? This book will be of interest to anyone with a professional or academic interest in evaluating the quality of educational or psychological assessments, measurements and diagnoses.

The Test of English as a Foreign Language TM (TOEFL®) is used by more universities worldwide than any other test to assess English language proficiency for academic admission and placement decisions, and to guide English language instruction. This landmark volume provides a detailed description and analysis of Educational Testing Service’s research and development efforts to develop a major revision of the TOEFL® test. The result is a book that serves as a case study of test design drawing upon theory in the complex domain of English language proficiency while attempting to meet standards of educational measurement. Building a Validity Argument for the Test of English as a Foreign LanguageTM is distinctive in its attempt to develop a coherent story of the rationale for a test or its revision, explain the research and development process, and provide the results of the validation process. Through its treatment of one test, it expands on and tests principles and approaches to educational measurement, providing an in-depth, integrated perspective on the overall process of test revision. Moreover, because the conceptual foundation and history are presented alongside the empirical studies and validity argument, these sometimes disparate areas are presented in a way that demonstrates their connections – an approach which represents a departure from, or extension of, conventional materials on test revision. This volume is particularly relevant for professionals and graduate students in educational measurement, applied linguistics, and second language acquisition as well as anyone interested in assessment issues.

Tests for the measurement of language abilities must be constructed according to a coherent validity framework based on the latest developments in theory and practice. This innovative book, by a world authority on language testing, deals with all key aspects of language test design and implementation. It provides a road map to effective testing based on the latest approaches to test validation. A book for all MA students in Applied Linguistics or TESOL, and for professional language teachers

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.

This monograph provides a historical overview of validity, targeting developments in both the UK and the US. It explores theoretical notions of validity as well as pragmatic validation practices and expands the arguments that need to be attended to document quality. The authors examine the need to consider, in addition to the psychometric evidence, which has continued to prevail especially in the US, other critical sources of quality evidence. They call attention to principled design and the evidence accumulated from various departments/groups involved in test design and development. They also promote the concept of impact by design, which places consequences at the top of the evidence chain to guide all testing efforts and quality documentation. They envision validity scholarship to attend to consequences at the individual, aggregate/group, and larger educational/organisational/societal levels. Concomitant with this attention to consequences are considerations of stakeholders and the tailoring of communication to engage intended groups. Such an approach yields a more convincing validity argument. The monograph ends by calling on professionals in the field to publish case studies, which showcases localised validity arguments in practice. Local case studies represent critical endeavours to illustrate how evidence and arguments are pulled together to support the quality of a testing programme and all that it entails.
