What is a boundary?
In this particular context, the boundary we are talking about is not a physical obstacle, but a genre convention. Each genre has its own conventions and its the job of the professor to enforce those conventions. In a way, the professors expect their students to follow the conventions of the genre, which ultimately means that the conventions make up some part of their (the audience’s) expectations. However, oftentimes those conventions (if too strictly implemented) limit students’ creativity and individual voice.
