Topic cards are similar to scripts in that they can help students engage in a variety of topics, beyond their own interests. They are different in that they include just a few words that describe a topic that launch a student or group students in a particular direction.
A teacher had created a special lunch group to help a student at the middle school level engage in appropriate teen conversations. She had one main interest and it would dominate every conversation. Her interest was in princesses and everything having to do with them. For most young teen girls, princesses were not much of an interesting topic for them.
