At Elizabethtown, Tyminski has developed a certification program in special education as well as a concentration in special needs. Although she has taught a wide variety of courses, her primary areas of teaching focus on the areas of inclusion and cognitive, behavioral, physical and health impairments.

Tyminski earned a doctorate in education from Temple University in 1995 and bachelor’s and master’s degrees from the University of North Carolina at Chapel Hill. Prior to joining the Elizabethtown faculty, she taught at York College of Pennsylvania, coordinated and supervised a full inclusion program in Maryland, and taught special education students in the public schools of both Maryland and Pennsylvania.

Tyminski volunteers as an advocate to help parents of special-needs students understand their legal rights and to help parents obtain appropriate inclusion of their children in the regular classroom. Her writing interests include strategies for successful inclusion, inquiry-based teaching, service-learning and student teaching. In June 2005, she published a textbook, "Your Early Childhood Practicum and Student Teaching Experience: Guidelines for Success," to help college students enjoy a successful practicum and student teaching experience.
