How does Mr. R incorporate other cultures into class?

Today I asked Mr. R how he incorporated multiculturalism into his class. He began by telling me that each lesson has a cultural component integrated into the history and research section of the sketchbook assignments. For example, the 3D coil pot weaving project relates to Native American weaving techniques. All of his projects have the potential to be integrated into a multicultural curriculum. He also likes to think of his students from other cultures as well. Creating a self portrait or integrating a Western European culture project would also be considered a multicultural lesson for many of his students. The high school has many exchange students and students visiting from abroad. It is a great thing for them to experience the American culture as well. His answer was fairly short, but to the point. He integrates multiculturalism into every lesson that he can but he has never tackled an all encompassing "multiculturalism" lesson like our class did a few weeks ago. Because there are many language courses, and a specific "Multiculturalism" class offered at the high school, he knows that the students are getting similar information in other classes as well. Although he believes in cross-curricular development, he also thinks that art class is for creation of any sort of art, not just art from foreign cultures.
