Agenda enforcement: Sometimes students interrupt a discussion to ask about or remind others, and
especially the teacher, of an agreed-on agenda. If the teacher tells students to open their text to an incorrect page, for example, a student may raise her hand to correct the teacher—or even do so without raising a hand. This communication strategy is one of more public, direct ways that students influence activities in the classroom, but its power is limited, since it does not create new activities, but simply returns the class to activities agreed on previously.
