Dr. Thomas (Tom) Tretter is a professor of science education, the director of the Center for Research in Mathematics and Science Teacher Development (CRIMSTED), and the director of the university Gheens Science Hall and Rauch Planetarium in the College of Education and Human Development at the University of Louisville. He taught high school mathematics and science for 10 years prior to joining the U. of Louisville faculty in 2004. His passion for math and science education revolves around supporting students in making sense of their learning – understanding how and why; being able to plan and apply learning to new situations. His research focuses on domains of curriculum, instruction, and assessment, with a particular focus on preservice and inservice teachers, the learning of their students, and the systems in which they function. He also engages in numerous projects in collaboration with university engineering faculty in studying how to strengthen the learning of engineering students at the postsecondary level. He has led and participated in dozens of projects and played key roles in securing over $7 million to support efforts related to that work. His work includes interacting with others in the education community: classroom teachers, district administrators, state departments of education, and university faculty.
