For a six-week block in my 12th grade creative writing elective, focused on the craft of writing short fiction, I let students run the show... kind of.
Students are split into small groups, each of which leads a very structured class discussion on a short story that models a particular technique: characterization, point of view, symbolism/subtext, dialogue, non-linear plotting, etc. Students are also individually responsible for a creative, "non-fictional" response to the story they chose that presents the piece in a different light: they can compose music, adapt the story into a short film, etc.
Stories include student favorites like Karen Russell's "St. Lucy's Home for Girls Raised by Wolves," Joyce Carol Oates' "Where Are You Going, Where Have You Been," and Z.Z. Packer's "Brownies." Almost all of the stories are available full-text on literary journal websites or are in the public domain, and you can easily swap out the stories for whichever ones your students might find more useful.
Also included is the rubric I use to grade students when they lead class as a group.
