Deborah Loewenberg Ball delivered the address at the University of Pennsylvania’s Graduate School of Education commencement ceremony on Saturday, May 14. Ball urged the nearly 600 graduating Penn students to stand up for the power of teaching and seek to advance education and social justice throughout their careers. In her remarks, she compelled the graduates to “speak up about the power that good teaching has. Explain that it has to be learned, that it is not a natural talent. Promote its development. Stand up against interventions that take skillful teaching for granted, or overlook what it really takes to learn to do it.” She concluded her remarks by asserting that “the evidence is clear. The order for social justice in this country is long, tall, and overdue. Just remember that, among the resources for that societal change, is the power of teaching.”
