Allan Cohen
Director of the Georgia Center for Assessment; Director of the Institute for Interdisciplinary Research in Education and Human Development; Professor of Educational Psychology and Instructional Technology; Omer Clyde and Elizabeth Parr Aderhold Professor in Research Methodology
Co-Principal Investigator for PEG’s evaluation of Forsyth County Schools’ U. S. Department of Education Investing in Innovation grant
Dr. Cohen is an expert in educational measurement, item response theory, test development, and applied statistics. His research focuses on examining methodological issues in educational measurement primarily with respect to applications in test development, including problems dealing with the construction and maintenance of achievement tests; equating, detection of item bias, and estimation of item parameters under item response theory; and standards setting.
In the spring of 2011, a team of University of Georgia education researchers including Dr. Cohen received the 2011 Award for an Outstanding Example of an Application of Educational Measurement Technology to a Specific Problem from the National Council on Measurement in Education for their development of a new statistical method for measuring the growth of students’ problem-solving skills in mathematics. This new method enables researchers to simultaneously measure both the different ways that students can reason about individual questions on a mathematics test and their overall growth in mathematics ability.
Dr. Cohen is the Director of the Institute for Interdisciplinary Research in Education and Human Development. As a center within this Institute, PEG has the opportunity to collaborate with Dr. Cohen and other faculty and research specialists in the other centers of the Institute—the Learning and Performance Support Laboratory, the Georgia Center for Assessment, E. Paul Torrance Center for Creativity and Talent Development, and the Research, Evaluation, Measurement, and Statistics program.
