Assigned "the unessay" as the final project in my utopias and dystopias course and I have had, visual/film essays, audio essays with musical compositions, short stories, films, analyses of eurocentric knowledge, and so much more. I highly recommend this assignment.
I think you can develop a rubric that hits all the points of the assignment. I’ve been stressing intellectual engagement with the topic and the things we’ve discussed over the course of the semester.
