A Semester in Purgatory: At the Intersections of Pedagogy, Interpellation, Queerness, and Mourning records an unusual project---one often attempted mid-career, rather than as a dissertation. It traces the process of developing pedagogy---from work gleaned in an academic practicum to experiences in the classroom---while incorporating the perspective of a generalist who is teaching three distinct periods in that semester being recorded (classics, medieval/early modern, composition). Concomitant to the research concerns in the project is the subjectivity of mourning, as my teaching and writing occur in the literal aftermath of my mother's sudden death, which necessarily becomes part of the project as it spectrally descends on my classroom, and my life. The dissertation thus considers a selection of important articles on the development of teaching (Elbow, Bartholomae, Perl, et al), while considering concerns of truth in autobiography (using Coetzee as a platform to works by Althusser, Williams, and Sontag) and the effects of mourning (both in narrative form, with writers such as Didion and Kincaid, and in psychological form, a rumination on the works of Melanie Klein and Silvan Tomkins). This dissertation emphasizes the development of an authentic personal voice---in writing and teaching---while also considering the identity politics and possible spaces for interpellation that complicate the classroom and personal pedagogy.
