Paul J. Riccomini began his career as a dual-certified general education mathematics teacher, teaching students with learning disabilities, emotional and behavioral disabilities, and gifted and talented students in Grades 7-12 in inclusive classrooms. His teaching experiences required a strong content knowledge in mathematics and the development and maintenance of strong collaborative relationships with both general and special educators. Currently, he is an associate professor of special education at Clemson University. His research focus is on effective instructional approaches, strategies, and assessments for students who are low achievers and/or students with learning disabilities in mathematics. He has written several research and practitioner articles related to effective strategies for teaching mathematics to students who struggle as well as coauthored two math intervention programs targeting fractions and integers. As a former middle and high school general education and special education mathematics teacher, Riccomini knows firsthand the challenges and difficulties teachers experience day-to-day when working with struggling students. He earned his doctorate in special education from The Pennsylvania State University and his master's of education and bachelor of arts in mathematics at Edinboro University of Pennsylvania.
