I rarely understand "otherwise" meaning in this sentence. I think it's not normal meaning(in circumstances different from those present or considered; or else).
please tell me what this mean.
this is full passage
While many teachers say they are keen on the idea of participatory pedagogy, they often have little understanding of what participatory practices entail, and are, in fact, impervious / inimical to change; even when they think they are doing otherwise, observations show that teachers perpetuate the teacher-centered classroom practices to which they have been habituated.
