{"product_id":"methods-for-identifying-biased-test-items","title":"Methods for Identifying Biased Test Items","description":"This book is highly recommended for all involved in test  development  or who have any interest in the use of tests in education or in  other  fields. The necessary mathematics are presented clearly but  never  obscure the important messages in the book. It will certainly be  referred to constantly in my future work in this area.  --Educational Research  \"The fundamental goal of the Measurement Methods for the Social  Sciences series is to make complex measurement concepts, topics,  and  methods available to readers with limited mathematical  background but  a strong desire to understand, as well as use, methods that are  on  the forefront of social science assessment.  With this book on  item  bias detection methods, Gregory Camilli and Lorrie Shepard have  achieved this goal admirably.\"  --from the Foreword by Richard M. Jaeger  What can item bias methods do--and not do--when applied to real  test  data? Aimed at helping researchers understand how item bias  methods  work, this book provides practical advice and specific details  on the  most useful methods for particular testing situations. Beginning  with  a review of early bias methods and the fairness issues  associated  with the topic of test bias, the authors explain the logic of  each  method in terms of how differential item functioning (DIF) is  defined  by the method--and how well the method can be expected to work  in  various situations. In addition, chapters include a summary of  findings regarding the behavior of the various indexes in  empirical  studies, especially their reliability, correlation with known  bias  criteria, and correlations with other bias methods. The book  concludes with a set of principles for deciding when DIF should  be  interpreted as evidence of bias.","brand":"SAGE Publications Inc","offers":[{"title":"Default Title","offer_id":54246775587160,"sku":"9780803944169","price":137.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780803944169_b51661e1-6847-4ef0-b7ff-cde17bfc4f02.jpg?v=1777787120","url":"https:\/\/agendabookshop.com\/products\/methods-for-identifying-biased-test-items","provider":"Agenda Bookshop","version":"1.0","type":"link"}
