I'm a big fan of CSC - culturally specific content. Students enjoy and learn more / speak more, if you use their cultural vantage point and knowledge as the basis of discussion and learning.
OUP Smart Choice is a new textbook coming out soon. Great that textbook makers are doing more to provide CSC. They are offering free samples. Nice easy explanations on how to use in the classroom are offered. See them below and get the feel for this powerful material!
