The purpose of developing this handbook is to orient teachers to look for the interconnected and interdependent nature of social and ecological issues about which they teach in class. Usually, in our textbooks, the issues are presented in a bounded nature within the framework of different nation-states. However, the social and political life within the boundaries of the nation-states is deeply influenced by the events happening outside these political boundaries, This phenomenon is not new, but globalization and the penetration of information and communication technology in our lives have made it more pronounced. This Handbook aims to equip the teachers with the ability to make connections between the events occurring globally. The Handbook aims to highlight the interconnected and interdependent nature of social, political and ecological issues beyond the boundaries of the nation-states.
