Robert Mayes received his B.S. (1979) and M.S. (1981) in Mathematics Secondary Education from Emporia State University and Ph.D. in Mathematics Education from Kansas State University (1989). He taught mathematics on the high school, community college, and university levels. In his tenures at West Virginia University, University of Wyoming, and University of Northern Colorado he specialized in teaching mathematics for teachers through distance education programs, served as Co-PI on three major NSF grants and an Upward Bound Mathematics and Science grant, and wrote ACT in Algebra, a text for an applied technology driven college algebra course. He has been the Director of four science and mathematics education institutes, the most recent being the Institute for Interdisciplinary STEM Education at Georgia Southern University. He has expertise in interdisciplinary STEM education and mathematics education (6-12 and undergraduate levels), including model-based reasoning, computational reasoning, design-based reasoning, and quantitative reasoning, mathematical modeling, problem solving, undergraduate Quantitative Biology, and development of online graduate programs in mathematics and STEM education.
