ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book analyses the concept of teacher leadership within the broader concept of leadership conceived as an influencing process instead of a narrower focus on the managerial or administrative roles of teachers, which can often dominate understandings of teacher leadership in empirical studies. It explores teachers' influence on students and on parents, on the profession, and in the wider community, as well as the range of avenues for influence within schools on matters to do with teaching and learning. The book deals with the implications that Internet-based learning has on teacher leadership, which has traditionally been viewed as school-based, or even classroom-based. It also deals with some key terms that may not be explicit in their ordinary definitions or as they are used in other theories.
