 These schools prohibit or discourage students from communicating in their first language during class hours and have traditionally employed school-wide policies punishing children for speaking in the minority language during the school day between each other.Transition models, in contrast, do use the student's first language initially as a bridge to monolingual instruction, but ultimately also seek to shift the state to a monolingual and monocultural society.Proponents of these models claim that children may be stigmatized for speaking an indigenous language and that Spanish provides more upward mobility.
