"Molly is impressed with these responses. She knows there is a tendency to underestimate 'average' students in 'regular' classrooms, and she laughs off the skepticism of those who doubt her students' ability to read insightfully and through multiple lenses."
I think most students have the ability to learn literary theory and apply it. The key consists of adapting, scaffolding and differentiating appropriately to the particular learners you have to teach. If students fail to apply literary theory then, most likely, the fault lies in the teacher. When my students are unable to complete an assignment appropriately, first I always ask myself what I should have done better. Students will not all be at the same intellectual level or even have certain skills developed , but that's why teachers need to differentiate and adapt their teaching to meet students halfway.
