Some have suggested that the world is moving towards a global society, in which the various countries and peoples of the world are becoming more interconnected and interdependent. For a global society to function well, its members need certain attitudes such as a desire for cooperation, mutual understanding and respect, as well as continuous and self-motivated learning. A model of education is needed that engenders these attitudes such that students critically understand these attitudes instead of passively accept them. This kind of education requires leadership that agrees with and engages in, the same attitudes. This book proposes a model of educational leadership for a global society and presents an exploration and comparison of public high schools across three countries in terms of this model.
