A central tenet of critical pedagogy maintains that the classroom, curricular, school structures teachers enter are not neutral sites waiting to be shaped by educational professionals. While such professionals do possess agency, this prerogative is not completely free and independent of decisions made previously by people operating with different values and shaped by the ideologies and cultural assumptions of their historical contexts. These contexts are shaped in the same ways language and knowledge are constructed, as historical power makes particular practices seem natural—as if they could have been constructed in no other way.
