MAILING LISTS

I have a class of 66 undergraduate medical students (11 groups). I am
leading an epidemiology course and this is my first shot at TBL.  

 

This is mid-way through the semester and one of my groups is having
difficulty. Their group learning behaviors have deteriorated over
time-the group has divided into two smaller groups that cannot get along
with each other.  They come into my office separately to complain (I now
do not allow that), meet with each other to study outside of class
separately, and don't work together in class (at the last second they
vote on which answer will be used-but they don't discuss the issues
together at all anymore).  

 

I have met with them as a group twice to address this obvious problem
(that they all agree that this is a huge problem for them). I have had
them discuss openly the nature of the problem and what they might do to
overcome it, and helped them to brainstorm the specific strategies that
they can use to learn in groups. Every intervention seems to lead to
further deterioration of their group.

 

I have been told NOT to intervene too much, as this is something they
need to work out on their own.  I am, however, worried that they cannot
work it out.  Suggestions?
