Progressive Stack
“Progressive Stack is a form of leading discussions which involves a facilitator keeping a list of names of people who wish to speak. The facilitator scans the group during discussion and if someone wishes to speak, they raise their hand and catch the facilitator's eye. The facilitator nods and makes eye contact to indicate the person is now put on the list to speak, and then the person can put their hand down so it does not distract other discussion participants. However, the facilitator does not simply write a list of names in the order that people raise their hand. Rather, if someone who has not spoken raises their hand, they go to the top of the list. If someone who is of an oppressed group or identity, or of a group or identity that is unrepresented in the conversation raises their hand, they go to the top of the list unless they have already contributed significantly to the discussion.“
