Students get bored with the same routine.
Students may also think the teacher is a little lazy if he or she doesn't take the time to change the class. A class that is always changing is more dynamic. If a student's group was dull the last time, the next group may be better. I've noticed classes that I constantly change are more closely knit. Students become more familiar with each other and learn each other's personalities.
