For "first-timers," I select a comedy. To increase students' knowledge of the historical background, I drag out old encyclopedias, updated with neat facts and photos printed off the internet. I divide the class into four groups. The groups put the desks together like conference tables, one in each corner. For the rest of the class, each group works as a team to research their topic: The Globe Theatre, Elizabethan Apparel, Players: The Lord Chamberlain's Men/The King's Men, and Queen Elizabeth.
The next day, each group forms a "panel of experts" to present their mini-research to the class. For all interested students, I offer extra credit projects like: build a model of the Globe Theatre, or sew an article of Elizabethan clothing, etc.
To overcome the "language barrier," I use one of the compilations by Charles and Mary Lamb, Tales of Shakespeare. If the class has extreme difficulty, I copy the synopsis from the book and we read that and watch a PBS or A&E version of the play. Even if we only read the synopsis and watch the video, we hold discussions, write essays, do projects, and take a test. With average classes, before we read an act, I read the synopsis. Knowing what will happen ahead of time in no way hinders their appreciation of the play, if anything, it helps!
To make the reading more interesting, I move the desks into a semi-circle. I assign the main parts to the strongest readers, giving myself a crucial character's part for them to interact with. The weaker readers get bit parts, sound effects, etc. I try to seat characters that interact often near each other in groups.
