This publication, the result of the collaborative work of the Network of educators for global citizenship, is a proposal for reflection and practical examples regarding the transformative nature of Education for global citizenship, being essential that for this educational approach that its actions educational activities are aimed at promoting critical thinking, dialogue, collaboration, solidarity and commitment to transform inequalities and promote social justice, equity and sustainable development. The methodological approach, therefore, must also be transformative and the strategies that accompany processes, promote this social transformation. Transformative methodologies are inherent to Education for global citizenship and the methodological processes that contribute to the construction of schools for global citizenship, in our opinion, should be based on three different pillars: promote the transformative dimension of education to build another world possible and necessary, promote a socio-affective approach focused on solidarity and cosmopolitan empathy and promote the construction of a more participatory and integrated curriculum that generates meaning in teachers and students.
