In 1985, a group of teachers and academics began what was intended to be a two-year, collaborative, action-research project they called the Project for Enhancing Effective Learning (PEEL). At the end of two years they found that, for several reasons, they could not stop and PEEL has continued to the present day during which time it has spread to over 20 schools in Australia and overseas. The paper draws on the experiences of the past nine years with PEEL groups and addresses three questions: what issues of teacher change, and especially of long-term teacher change emerged over nine years? What are characteristics of successful school-tertiary collaboration? Is it realistic to hope for the widespread emergence of teacher-researchers?
