An accomplished researcher and lecturer, Dr. Peska is a visiting faculty member at the Harvard-Macy Institute at Harvard University. The Harvard-Macy institute is an inter-professional, international incubator for innovators in health care education. The institute takes a collegial “think tank” approach to continuing professional development, bringing together diverse perspectives in health care education. It inspires participants to examine their own assumptions and behaviors in a new light, leading to fresh approaches to their careers and their capacity as leaders of organizational change.

Under Dr. Peska’s leadership at TCOM, he and his team successfully increased the overall class size and established the TCOM Academy of Medical Educators. The Academy provides protected time for faculty to attend to their teaching assignments and brings them together each week for their own development. They participate in a longitudinal curriculum that provides in-depth discussion in the learning sciences and coursework that includes theory, instructional design, assessment, skills training, technology, and other facets of curriculum delivery. Time is dedicated for reflective dialogue on outcomes of recent courses and sharing of best practices. The Academy members were responsible for modernizing and integrating the curriculum. The overall success of the academy and other leadership strategies contributed to achieving excellent outcomes for TCOM’s students and an increase in overall faculty and institutional pride. Since inception TCOM students have exceeded the national means for first attempt passage and total scores on all levels of COMLEX-USA, the licensing board exam required of all graduates of osteopathic medical schools. Additionally, the majority of TCOM students sit for USMLE Step 1 where they also performed at or above the national average of all allopathic medical schools.

Dr. Peska’s Perspective on Medical Education: “Although comfortable with and experienced in clinical practice management and oversight of a modest research enterprise, my core interests are in curriculum and instruction and team development. The application of evidence-based principles of learning to medical education has enhanced institutional effectiveness at TCOM. With several complimentary degree programs on the health science center campus and in the community TCOM has successfully partnered internally and externally to promote inter-professional practice. Our team has been invited to present its strategies and outcomes in the United States and overseas.” – Don N. Peska, DO, MEd, FACOS
