At the beginning of a class, especially a conversation/discussion class, beginning by going over the “rules of engagement” or rules for class discussion. After some discussion of guidelines and what they might be, have students brainstorm the rules in groups. Then collect them and compile them, eliminating redundancies, as there will probably many similar rules, such as “don’t interrupt others” or “listen to the speaker.” Type them up and give them out at the next class session as the rules for the term.
This activity not only leads to discussion of appropriate behavior in groups but also leads to more compliance as students are more likely to follow the rules they set up themselves. It also teaches students the democratic process in establishing their own rules.
