Bøger af Steven J. Osterlind

A unique, practical manual for identifying and analyzing item bias in standardized tests. Osterlind discusses five strategies for detecting bias: analysis of variance, transformed item difficulties, chi square, item characteristic curve, and distractor response. He covers specific hypotheses under test for each technique, as well as the capabilities and limitations of each strategy.

This new edition presents an up-to-date description of differential item functioning. It describes varying procedures for addressing this process in practical testing contexts and presents useful examples and studies that readers may employ as a guide in their own work

Finally, this book presents a compendium of important issues about test items, including procedures for ordering items in a test, ethical and legal concerns over using copyrighted test items, item scoring schemes, computer-generated items and more.
