In this book, the NCSM suggests that student achievement in mathematics is unlikely to improve significantly beyond current local, regional, state, national, or provincial levels until mathematics education leaders assume and exercise professional responsibility and accountability for their own practice and the practice of the teachers they lead. Accordingly, this book identifies the specific principles, indicators, knowledge, and skills necessary to lead others beyond the current reality of student performance in mathematics into a focused, more equitable, and successful future. The framework identifies the key leadership principles in four domains of mathematics leadership: equity, teaching and learning, curriculum, and assessment. It goes on to identify three specific indicators of leadership in each domain. Each indicator is further broken down into specific actions that fall on a continuum of three stages of leadership growth: 1) knowing and modeling leadership; 2) collaborating and implementing structures for shared leadership on the local level; and 3) advocating and systematizing improvements into the wider educational community. The framework concludes with tools for reflection, self-evaluation, and discussion.-- Back cover.
