It was interesting to watch the change in the children when they were told they were better, smarter and privledged. The suppressed students' body language changed, their attention to thinking changed and their relationships changed. It's a great way to get the message through to children and as a teacher, I've done similar things in my classroom. I just wonder how long their learning lasts and how it impacts how they approach people of color.
You may never know until later in their lives. Keep changing the narrative though!
