English to Greek Other Public Education/Social Science/Politics

"Study Circles" are a forum in which people from diverse racial and cultural backgrounds come together to learn from each other's life stories, or, more generally, in which people try to find common ground over controversial subjects. Generally, 10-12 people will sit in a circle, engaging in a facilitated dialogue with one another. These sessions continue weekly for 5-10 weeks. We are trying to locate a chapter of the Study Circles program that has incorporated using the Greek translation of the term "study circles." Its name may be a fairly literal translation of the two separate words, or it may be something more conceptual encompassing the complete phrase. For further explanation, see http://www.studycircles.org/.
Any suggestions for a serviceable translation would be much appreciated.
