Getting students to read is the toughest part of an English teacher's job. We can get them to sit down, be quiet, look at the page, but we really have no control over whether they read or not. These questions have been refined over years of teaching Othello. They address the lines and segments that I want to discuss in class. These questions cannot be sparknoted or shmooped in their entirety. The kids have to read the actual text in order to get these. These questions go in order with the text.
I don't always grade them. Sometimes I spot check, but I will not give a re-test for a test or quiz until I see that the kids put some effort into the questions.
