The Scarlet Letter is a treasure trove of topics awaiting exploration by readers of Nathaniel Hawthorne's romantic opus. Whether looking for imagery (light/dark, mirror, scarlet letters), symbols (static or evolving), ironies, etc., there are more than enough subjects to go around. Consider assigning groups a research question/topic before beginning the novel so that they can mark support as they read. Then show your class this student-produced presentation as a model for them to critique before crafting their own presentation.
