Contested Spaces of Teaching and Learning examines the educational experiences of adults as cultural practice. These practices take place in diverse settings from formal educational contexts to institutionally interstitial realms to fluid and explicitly contested everyday spaces. This edited collection includes twelve richly rendered ethnographic case studies written from the perspective of practitioner-ethnographers who straddle the roles of educator and ethnographic researcher. Drawing on distinct theoretical framings, these contributors illuminate the ways in which adults engaged in teaching and learning participate in cultural practices that intersect with other dimensions of social life, such as work, recreation, community engagement, personal development, or political action. By juxtaposing ethnographic inquiries of formal and informal learning spaces, as well as intentional and unintended challenges to mainstream adult teaching and learning, this collection provides new understandings and critical insights into the complexities of adults’ educational experiences.
