Yes, I sure do. However, it's refreshing to re-assign students to new groups in order to keep things interesting, allowing new group members to get acquainted. The new groups have the same mix of learning styles, just like the previous groups. Isn't it strange that the classroom seating arrangement (chairs in rows all facing to the front of the class) has not changed in the past 200 hundred years? I make an effort to arrange the seating in a circular fashion, no matter what we are doing … lecture, discussion, etc because the circular arrangement immediately raises the classroom energy-level and students start inter-actioning with one another.
