Let me tell you a funny story about technology in the classroom. I was teaching English at a charter school in Boston a few years ago, and my classes were working on "Macbeth." I'm always looking for new angles of attack, especially with Shakespeare, so I decided to focus on different interpretations and stagings of the play. I cut scenes from a variety of movie versions of Macbeth and showed them to my classes, so we could compare the difference. I used a Royal Shakespeare company version. I used the movie "Scotland, PA," a wonderful modern adaptation in which Macbeth's is a fast food restaurant. But my favorite of all was the Roman Polanski version, produced with funding from Hugh Hefner.
