This paper examines the relationship between Heidegger's critique of educational comportment and his analysis of space in "Being and Time." It posits that providing an educational corrective to the practice of tacit rational, described as "circumspection" in "Being and Time," would provide an opportunity to reorient Dasein toward clearer awareness of the spatial context. A phenomenological approach to education might be framed as a process that reorganizes how changes are anticipated by comported expectations. Addressing conditions of spatial comportment in education reveals that while models of learning illusorily claim to provide infinite opportunities, contingent upon mastery of delimited knowledge, a phenomenological approach to education begins by first delimiting illusions of possibility.
