Book excerpt: The global economic meltdown has highlighted the interconnectedness of nations. This book seeks to provide an overview of topics, issues, and best practices related to defining social justice leadership given our increasingly global world. Refugees and immigrants from around the globe now inhabit schools and institutions of higher education across the nation and US students, teachers, and leaders are traversing international boarders both physically and virtually through international collaboration, technology, and exchange programs. Although there have been increased efforts and scholarship in support of diversity and multicultural awareness, these efforts have largely focused on the US. We acknowledge that many leadership theories are “domestic” in that they typically incorporate US perspectives or a single-culture description of effective leadership. This book provides a deeper understanding of diverse and multicultural perspectives as they relate to a world that is becoming increasingly interconnected economically, socially, and culturally. Particular attention is paid to providing specific strategies for social justice leaders working in PK-12 and/or higher education, and leadership preparation programs to promote effective leadership that reflects multicultural understanding of the diversity both within and outside the US. Within the context of leadership practice, internationalization offers new insights and ideas about leadership aims, processes, and competencies as a means for addressing equity concerns throughout PK-20 education.
