This introduction to the second part of our Symposium on Teachers as Leaders examines the role of collaboration and writing as part of teacher leadership. The first part of the symposium described teacher leadership as a stance that values professionalism and the intellectual, political, and collaborative work of teaching. This introduction explores how a group of teacher leaders who have met regularly during the past several years have used writing to reflect on practice, to share ideas with one another, and to communicate their perspectives to others. [For the introduction to Part 1 of the symposium, see EJ1110798.]
