Possibly using the educational definition of it, cribbing from the wikipedia page;I don't think Reeebeca is using it right though.
It's basically a Marxist approach to education, that in order to liberate countries where minorities are kept under thumb - they need to be taught that the government or regimes they live under is unusual or wrong and, once educated, will be more capable of breaking free of governmental control.Paulo Freire defines praxis in Pedagogy of the Oppressed as "reflection and action directed at the structures to be transformed.Through praxis, oppressed people can acquire a critical awareness of their own condition, and, with teacher-students and students-teachers, struggle for liberation
It's not entirely off in that educating these groups will make a difference to the people, but learning to read and write probably still isn't going to lead to an end of an oppressive government. But Praxis still considered an important aspect of curriculum design anyway. That said I'm pretty sure that person tweeting is just putting out buzz words to look important anyway
