In the United States, the nomenclature of adult education includes adult literacy, adult secondary education, and English for speakers of other languages (ESOL) services provided to undereducated and limited English proficient adults. Those receiving adult education services have diverse reasons for seeking additional education. With the passage of the WIA, the assessment of adult education students became mandatory-regardless of their reasons for seeking services. The law does allow the states and local programs flexibility in selecting the most appropriate assessment for the student. The purpose of the NRC's workshop was to explore issues related to efforts to measure learning gains in adult basic education programs, with a focus on performance-based assessments.

Statistical evaluation of diagnostic performance in general and Receiver Operating Characteristic (ROC) analysis in particular are important for assessing the performance of medical tests and statistical classifiers, as well as for evaluating predictive models or algorithms. This book presents innovative approaches in ROC analysis, which are releva

GEOFF NORMAN McMaster University, Hamilton, Canada CEES VAN DER VLEUTEN University of Maastricht, Netherlands DA VID NEWBLE University of Sheffield, England The International Handbook of Research in Medical Education is a review of current research findings and contemporary issues in health sciences education. The orientation is toward research evidence as a basis for informing policy and practice in education. Although most of the research findings have accrued from the study of medical education, the handbook will be useful to teachers and researchers in all health professions and others concerned with professional education. The handbook comprises 33 chapters organized into six sections: Research Traditions, Learning, The Educational Continuum, Instructional Strategies, Assessment, and Implementing the Curriculum. The research orientation of the handbook will make the book an invaluable resource to researchers and scholars, and should help practitioners to identify research to place their educational decisions on a sound empirical footing. THE FIELD OF RESEARCH IN MEDICAL EDUCAnON The discipline of medical education began in North America more than thirty years ago with the founding of the first office in medical education at Buffalo, New York, by George Miller in the early 1960s. Soon after, large offices were established in medical schools in Chicago (University of Illinois), Los Angeles (University of Southern California) and Lansing (Michigan State University). All these first generation offices mounted master's level programs in medical education, and many of their graduates went on to found offices at other schools.
