The present focus of my research, extension online courses for teaching early literacy is aimed at eradicating functional illiteracy in Brazil, to form critical readers of texts circulating socially, able of writing what is appropriate to their pragmatic intentions, in different communicative situations. The instrument to achieve this goal is Scliar Early Literacy System (SSA), which contains the proposal foundations, the methodology, the instructions for applying the Units in the classroom, the reading and writing books for both teachers and students and the students' respective activity notebooks. This research goal is the teachers’ continuous training for improving young people and adult education, adopting a cutting-edge methodology, inspired by linguistic, neuroscience, neuropsychology, psycholinguistic and sociolinguistic advances. In this paper, I will deal with how to reach a qualitative leap in early literacy among young people and adults, changing the foundations that guide the mediator’s training, the methodology and the pedagogical material, from a perspective associating human and biological sciences. We cannot separate culture from the biological, from the brain, whose structure and functioning make its emergence possible.
