Although most of the literature of reform and systemic change focuses on policy, programs, and practices that the leaders should be responsible for producing, this chapter will emphasize what is known about how leaders bring about these improvements and what the research says about the skills, behaviors, and leadership styles of effective leaders. Finally, this chapter will highlight the concept of distributed leadership as presented in the National Science Education Standards. This free selection includes the Table of Contents, Foreward, Preface, and Introduction.
