I'm interested in your staff member's idea to embed the Juneteenth study within a communications unit. I appreciate how it avoids appropriation of "celebrating" an event that does not culturally belong to your enrolled families. Yet you are exposing children to an important part of American history and introducing a celebration they will encounter later as they become part of a wider community.
The naeyc standard, as I understand it, seeks to avoid the practice of cultural tourism: popping all sorts of "celebration lite" events into a curriculum, without really looking at deeper issues of everyday bias and how to create meaningful inclusion.
In teaching about Juneteenth in the context of communications, you are able to include Black American experience in a framework that makes developmental sense to the age group, and offers a deeper context for the origins of this holiday. At the same time, it does not preclude looking at why the holiday is meaningful and important to all of us currently.Please keep reporting on how this evolves!
