Hi Melissa,
I'm wondering if you're looking for help communicating with groups that are being guided by a staff member or docent or groups that are self-guiding? We send chaperone information to group organizers in both instances and I'm happy to send you those documents. We also found that having some of these documents translated into multiple languages has helped for our audiences.
On the day of the visit, we have a staff member or docent address the chaperones directly. I typically encourage docents to speak to their chaperones before the start of their tour: introduce themselves, shake their hands, and thank them for helping out that day. This usually gets chaperones more bought-in to acting in a support role.
All that being said, we still have chaperones who are disengaged and sometimes are not modeling the behaviors we'd like to see in the museum (e.g., playing with their cell phone, not staying with the group, and even touching works of art!).
