Hi Flora! For interactive groups the implementor will create groups with heterogenous and diverse participants. In their group, participants will then rotate around stations in a room every 10-15 minutes. At each station will be a problem or activity that the group needs to complete together and a ‘volunteer.’ The aim is for the group to work together to create the solution and for the volunteer to support this by encouraging participation and collaboration from the group members.
I hope this helps but would love input from others about what has worked in their settings!
