My Student-asked Question Based on Bruffee

Is collaborative learning between a tutor and a tutee as affective as collaborative learning between students of the same class?

Page 642, "The kind of conversation peer tutors engage in with their tutees, for example, can be emotionally involved, intellectually and substantively focused, and personally disinterested."

So, can the same be said for a class where the students aren't "personally disinterested?"

-In a classroom the students all share the same assignments and therefore the same basic ideas will bounce around. With the students working, ultimately, for the same goal, many of the paper will have the same ideas and be very similar. Constrastingly, the collaboration between a tutor and a tutee doesn't involve the idea that both are working to come to the same ideas. Instead, the tutor is helping the tutee come up with, and develop, ideas for only his/her paper.
