Jason C. Immekus – författare

This new text provides the most current coverage of measurement and psychometrics in a single volume. Authors W. Holmes Finch, Brian F. French, Jason C. Immekus, and Shenghai Dai first review the basics of psychometrics and measurement, before moving on to more complex topics such as equating and scaling, item response theory, standard setting, and computer adaptive testing. Also included are discussions of cutting-edge topics utilized by practitioners in the field, such as automated test development, game-based assessment, and automated test scoring. This book is ideal for use as a primary text for graduate-level psychometrics/measurement courses, as well as for researchers in need of a broad resource for understanding test theory.Now in its second edition, Educational and Psychological Measurement features new material on:Ethical and fairness issues in testing, quality control in testing, alternative measurement models and scaling methods for psychological assessment, computerized assessment, and application of machine learning methods. It also contains pedagogical features such as “How it Works” and “Psychometrics in the Real World” boxes that break down important concepts through worked examples and show how theory can be applied to practice.End-of-chapter exercises allow students to test their comprehension of the material, while suggested readings and website links provide resources for further investigationA collection of free online resources includes the full output from R, SPSS, and Excel for each of the analyses conducted in the book, as well as additional exercises, sample homework assignments, answer keys, and PowerPoint lecture slides

The book will be designed primarily for graduate students (or advanced undergraduates) who are learning psychometrics, as well as professionals in the field who need a reference for use in their practice. We would assume that users have some basic knowledge of using SAS to read data and conduct basic analyses (e.g., descriptive statistics, frequency distributions). In addition, the reader should be familiar with basic statistical concepts such as descriptive statistics (e.g., mean, median, variance, standard deviation), percentiles and the rudiments of hypothesis testing. They should also have a passing familiarity with issues in psychometrics such as reliability, validity and test/survey scoring. We will not assume any more than basic familiarity with these issues, and will devote a portion of each chapter (as well as the entire first chapter) to reviewing many of these basic ideas for those not familiar with them.We envision the book as being useful either as a primary text for a course on applied measurement where SAS is the main platform for instruction, or as a supplement to a more theoretical text. We also anticipate that readers working in government agencies responsible for testing and measurement issues at the local, state and national levels, and private testing, survey and market research companies, as well as faculty members needing a practical resource for psychometric practice will serve as a market for the book. In short, the readership would include graduate students, faculty members, data analysts and psychometricians responsible for analysis of survey response data, as well as educational and psychological assessments.The goal of the book is to provide readers with the tools necessary for assessing the psychometric qualities of educational and psychological measures as well as surveys and questionnaires. Each chapter will cover an issue pertinent to psychometric and measurement practice, with an emphasis on application. Topics will be briefly discussed from a theoretical/technical perspective in order to provide the reader with the background necessary to correctly use and interpret the statistical analyses that will be presented subsequently. Readers will then be presented with examples illustrating a particular concept (e.g., reliability). These examples will include a discussion of the particular analysis, along with the SAS code necessary to conduct them. The resulting output will then be discussed in detail, focusing on the interpretation of the results. Finally, examples of how these results might be written up will also be included in the text. It is hoped that this mixture of theory with examples of actual practice will serve the reader both as a pedagogical tool and as a reference work.

We envision that this text will (a) patiently wait on some office shelves begging to be handed to a student as a resource, (b) have a permanent home on desks where it continually rises to the top of the stacks for daily use of the applied researcher, (c) be happily carried in bags to and from work and class by the graduate student learning techniques, (d) be listed proudly as a reference text on syllabi, and finally (e) as an occasional drink coaster while deep thoughts are pondered about how to solve measurement problems. We hope that through such uses, particularly the latter, that we have provided some insight and assistance to the user in appropriately applying the techniques and concepts discussed.

Given that many practitioners in academia, government and private industry use SPSS for statistical analyses of testing data, we believe that our book will fill an important niche in the market. It will contain very practical information regarding how to conduct a wide variety of psychometric analyses, along with tips on interpretation of results and the appropriate format for reporting these results. We believe that it will prove useful to individuals in educational measurement, psychometrics, and survey and market research.Our text will add to the literature by providing users with a single reference containing the major ideas in applied psychometrics with instructions and examples for conducting the analyses in SPSS. In addition, we will provide original macros for estimating a variety of statistics and conducting analyses common in educational and psychological measurement.

Applied Psychometrics Using R Software is a hands on guide for anyone who needs to evaluate the quality of educational, psychological, or survey-based measures with confidence and clarity. Blending accessible theory with practical application, this book walks readers through the essential tools and techniques of modern psychometric practice—always with an eye toward real world use.Each chapter tackles a core measurement topic, from item analysis and reliability to generalizability theory, validity, scoring, item response theory, equating, and differential item functioning. Concepts are introduced with just enough technical grounding to build understanding, followed by step by step demonstrations in R that show how to implement, interpret, and communicate psychometric analyses in practice.Designed for researchers, practitioners, and graduate students, this book aims to be the resource that gets pulled off the shelf again and again: the volume handed to a student who needs a clear explanation, the reference that steadily rises to the top of a working researcher’s desk, the companion tucked into a graduate student’s bag on the way to class, the text proudly listed on syllabi, and—on occasion—the coaster beneath a mug of coffee during deep reflection on a stubborn measurement problem.Whether you are learning psychometric methods for the first time or refining your applied skills, Applied Psychometrics using R Software offers guidance, insight, and a bit of good natured companionship as you navigate the challenges of measurement in the social sciences.
