Last year was my first year teaching culture. I was given no curriculum or criteria. No one seemed to care what I taught, so I did what I thought the students would be interested in.
Popular topics were:
wedding culture (they know a lot about this, but I delved into the reasons behind some of our traditions. Homework assignment was to write about a wedding tradition from their hometown that differed from a western one.) Recommended movie: License to Wed with Robin Williams.
Women's movement in the 70s (most of my students were female). Effect this had on family life, jobs, etc. Toss in the cultural influence of the pill. I went out on a limb and taught about birth control options available in the west. Very positive feedback from the students ("no one talks to us about this stuff") and I didn't get fired.
University culture. So, so different from what they know. I had several students research their choice of a western university and do a ppt presentation for a major part of their grade. They had to tell about dorm life, club options, things to do on campus, how to choose classes, what subjects were available, class sizes, etc.
Half of my students are planning to be elementary school teachers. I did a lesson on early childcare options, elementary, middle and high school - west vs China. There are quite a few differences between the UK and the US once you get to the middle school level, so I pointed those out too.
Sports culture. Not so popular with my mostly-female students. They don't have the kid-sport culture (ie Little League, soccer mom syndrome) or inter-collegiate sport culture (college football or basketball).
Music. Can't lose with this one. Go as far back in history as you want. I'm spending at least a couple weeks on this in the coming semester. Assign genres or a period of time to several students and get them to do the work of researching and presenting. (Big band era, jazz, disco, drug culture, anti war songs, musicals, British invasion - there's no end to this, really).
Dating. Very popular with my uni students. How, where to meet a prospective boy/girlfriend. What activities constitute a date in the west? I found a website about the stages of a relationship and they wanted a handout with that info.
Elder care options. Many available in the west. I used situations pertaining to my actual family members to personalize it. Contrast with Chinese traditions.
Holidays. They know the major ones, but you can always do more. Have a Halloween party. That was successful for me last year and I'm doing it again.
That's what I can think of off the top of my head. My lesson plans from last year aren't available to me right now as I'm traveling. I've got 4 culture classes again this year, so will be getting my semester planned this weekend. Will add to this if there are any other good ideas I've forgotten about.
