I use this activity to teach positive/negative ethnocentrism. I included a powerpoint with 6 slides that I use to generate class discussion, provide the definition, etc. I also include a slide with 4 examples of video clips/music to use as visual examples. It's a great way to show how different cities can be cultural, yet show examples of healthy pride.
For the boston example I found a fantastic clip from Barstool sports that they put together to pay tribute to the Boston Marathon Bombing. It's a wonderful example.
I include a map of negative ethnocentism/stereotypes.
Attached as this is my outline/lesson ideas as to how this can be run and executed in the classroom. Feel free to use my plan, or change to suit your needs. Documents are on word and can be altered.
