This activity, based in experiences with popular education, is an introduction to the post/decolonial critiques to the concept of development. More specifically, it focuses on the following questions: What is development? Who defines what is a developed and a developing country? What is the criterion used to establish the above division? What are its consequences? To answer these questions, the students will analyze two countries, the United States and Cuba, using statistics from the Human Development Reports for the United Nations Development Programme. The activity aims to challenge students’ stereotypes about both countries and, especially, about the idea of development. Finally, the activity is designed to introduce students to post/decolonialism theories and it works better if the students had already been familiarized with the notions of imperialism and colonialism.
