Abstract
Recent legislative actions have mandated the professional development of teachers in hopes of improved student achievement. However, research has shown that mandated professional development most usually does not lead to a positive outcome. This article describes three aspects that have been identified as contributing to the transformation of instruction in schools: school context, role of the administrator, and cohesion between professional development and needs of students/teachers. Mezirow’s adult learning theory supports these important aspects of school reform and has implications for planning and developing educators’ professional development.
