Enhancing Professional Practice: A Framework for Teaching (ASCD, 1996, 2007) is used around the world for a range of purposes: teacher preparation, recruitment and hiring, mentoring and induction, professional development, and performance appraisal. But what makes these activities productive and of value to teachers are the professional conversations that accompany them, grounded in self-assessment and reflection on teaching and linked to clear standards of practice. This session will explore the lessons learned since the book's original publication.
