Ann O'Connell

Dr. Ann A. O’Connell is Professor of Educational Statistics, Measurement, and Evaluation in the Department of Educational Psychology at Rutgers University. She was formerly a Professor in the Educational Studies Department at The Ohio State University. Dr. O’Connell’s research interests are in multilevel and generalized linear models, the use of research evidence and evidence-based interventions, and evaluation of interventions in health and education. She is passionate about strengthening methodological capacity among applied researchers and working with her students and colleagues on evaluation of educational, health, and wellness initiatives. Dr. O’Connell is engaged in a variety of projects at local, national, and international levels. She was the Principal Investigator for a recently completed Methods Training Grant from the Institute for Education Sciences (IES), which was designed to strengthen capacity among schools, districts, and their higher-education partners for the selection and use of evidence-based interventions. Current efforts are expanding the curriculum to make all materials accessible to schools, districts and researchers nationwide. On an international level, Dr. O’Connell has an ongoing collaboration with Addis Ababa University (AAU) in Ethiopia, teaching courses in statistics and research methods and partnering with faculty and graduate students at the College of Education and Behavioral Studies (CEBS) at AAU to study STEM education and early childhood learning outcomes and teacher practices in Ethiopia. She received a Fulbright Scholar award in 2013-14 during which she taught at CEBS as well as Jimma University, University of Gondar, and Mekele University in Ethiopia. Dr. O’Connell teaches courses in Multilevel Modeling, Regression and Multivariate Analysis, Introductory Statistics, Sampling and Survey Research Methods, and other topics. She is an advocate for interdisciplinary science, and while at OSU developed and directed the Graduate Interdisciplinary Specialization in Quantitative Research Methods. Her research is published in the Journal of Research in Educational Effectiveness, Journal of Experimental Education, Journal of Educational Psychology, New Directions in Program Evaluation, and other outlets. She is the author and editor of a number of books on advanced statistical methods, and is the recipient of several awards, including the Educational Statisticians’ Outstanding Service Award, awarded by the American Educational Research Association, the Lorne H. Woolatt Distinguished Paper Award from the Northeastern Educational Research Association, and the College of Education Outstanding Award for Research, awarded by the University of Memphis.
