As a white woman, it take takes a while for some minority students to buy in to the mutual trust/respect needed in class. It has taken first semester to establish a trusting relationship with a group of African American girls in my 11th grade class. Now, we have a really great relationship, however, it seems like they are a bit too relaxed with me. They have a tendency to talk to each other at inappropriate times and often are distracting to others because of this. I've been very patient and have lightheartedly asked them to "bring it back in, girls", etc. to no avail. I have been wrestling with changing their seating arrangement to separate them all. They will be very angry about this. Do I risk it for the sake of order in the class or do I seek an alternative?
I would speak to these students first, and let them know the choice is theirs. They can respect your classroom or be moved from their current seating arrangement.
I agree that this is an appropriate solution. I can identify with this situation and have acted in exactly this manner myself.
Having a conversation with the, especially in light of the relationships you have built, is a great place to start. Let them know what their consequences will be, and let them choose the manner in which they want to respond to your requests.
