The ideas of the Cuban 'School of Literacy' are much less well-known in the west than Freire's Pedagogy of the Oppressed. This paper is an exploration of the theoretical and practical links between these two historic examples of popular education. The analysis is informed by our direct experience working and undertaking participatory action research alongside Cuban literacy specialists on adult literacy campaigns in Timor-Leste and Australia. These campaigns utilised a model known internationally by its Spanish name, Yo, Sí Puedo (Eng: Yes, I Can!). We also include material from interviews in Cuba with leading literacy academics and practitioners.
