Students volunteer or are recommended by staff, and then approached.
Alternatively, and possibly less effectively, students could be approached at random to join the discussions. The balance of age gender and year are considered informally. The atmosphere must be one of openness and mutual respect, with a clear agenda, and follow-up minutes. Briefing students in advance with the focus of the discussion allows prepared and considered responses and more efficient use of time in the meetings. The limitations of selected discussion groups must be made clear both to participants and to other students.
