service-learning and medical students

I am currently invovled in a project of community service learning for
medical students and am wondering if anyone can help me locate research
articles on the topic.  The particular area that I am currently looking at
is how we can improve the teaching of medical students through service
learning  and the most effective ways of doing this (ie: what we can do in 
the classroom and in the field to assist students to get the most out of
their
experience)

I would appreciate your help.  Many thanks
