Documenting and characterizing interactions between student interns and their mentors in the workplace offers perspective on student learning and enculturation that can help us introduce these ways of learning to students in the technical communication classroom, even before the internship. Three student intern conversations in the internship setting are the focus of this close discourse analysis, framed by 6-month-long case studies and Vygotsky's learning theory. Results indicate that many similarities exist between classroom feedback and mentor feedback in the internship, but that differences in student agency may make negotiation important in the technical communication classroom.
