Equalising the voices in the room
When facilitating, there's always louder and quieter people in the room.
Everyone has something useful to say so make sure to do all that you can to make space for the quieter folk.
One way of doing this is reversing the speaking order. Whenever someone puts their hand up or contributes a post it, get them to playback to the group in reverse order so that the more proactive speakers go last and the quieter get their say first.
That way the group's time and space isn't monopolised by the loud voices and everyone's voice can shine.
