Anthony Mackay sits down with Carol Campbell, associate professor of Leadership and Educational Change at the University of Toronto’s Ontario Institute for Studies in Education (OISE), to discuss teacher learning and leadership in today’s changing world. Campbell, whose research focuses on strengthening professional capacity to improve student opportunity, learning, achievement and equity, highlights the importance of teachers sharing and developing their own learning by engaging in professional learning opportunities. As an example, Campbell details the Teaching Learning and Leadership Program (TLLP) in Ontario, a joint initiative through a partnership between the Ontario Teachers’ Federation (OTF) and the Ontario Ministry of Education, in which teacher teams apply to receive funding to conduct a project linked to an area of student need they’ve identified. These teachers then become responsible for the professional learning of others and commit to sharing their knowledge and practice beyond their own school.
