Teacher learning doesn't end with initial preparation; many insights and skills remain to be added. This book is concerned with ongoing teacher learning, its goals (Part I) and pathways (Part II). It is based on a longitudinal study of 42 teachers: 20 over their first 8 years of teaching and 22 over their first 5 years. The areas of continued teacher learning identified in our study were: vision of teaching, program planning, assessment, relevance, subject content and pedagogy, classroom organization and community, inclusion, and professional identity. The pathways of learning included informal and formal PD, teacher inquiry, and school-based learning. A key finding of our research was that, over the years, teachers learn a great deal informally. However, they do so largely on their own and under considerable stress. Teachers need more support than they currently receive, both for survival and to enhance their informal learning.
