you need to develop your own response and understanding of the play, basically, become the director and know what you would have happen at different scenes. you also need to be able compare your response with those of others so go see a production of the play, the Harlos one, now showing at the bondi pavilion is quite amusing. The play is set in Nazi denmark, etc etc. just make sure your understanding of the play is yours and not someone elses, also read the rubric and the support document for teachers, both are very useful.
