The objective of this paper is to use psychoanalytic theory to examine how attempts at critical teaching in two English as a Second Language (ESL) classrooms related to changes in student subjectivity. The research critiques critical pedagogical assumptions regarding transformation and empowerment through a Lacanian perspective. More specifically, the persistent problem in critical pedagogy research--that it does not explore the effect of critical practices on student actions and beliefs--is examined. Based on a two-year study in ESL classrooms in the Southwestern U.S., this report uses case studies to outline types of changed comportments, or microtransformations, that students exhibited. Microtransformations are defined as instances in which small events trigger shifts in student practice and consciousness in ways that counter critical pedagogical narratives but are consistent with Lacanian theoretical perspectives.
