This methodology allows for group learning, but with a guided outcome. Participants are encouraged to work together to discover their own results, but at the end of the activity, it is appropriate for the facilitator to add some additional information. Whereas expository activities are grounded in opinion and new ideas, the brainstorming/guided discussion activities look for some sort of learned outcome. Wrap-up to these activities should be handled delicately; facilitators do not want to appear critical of or disappointed in participant results. Rather they should make additional suggestions or pose additional processing questions to help the group get to their anticipated end result.
