In my local area, there is a newsletter published by an attorney with a law firm that has some excellent articles from which you could use tidbits to create very interesting realistic scenarios. His name is Bob Gregg. At this link, go to Reading Room on the right hand side; then click Labor and Employment Law and you can see the archives listing of all the newsletters. Previous to my recent plunge into the e-learning design world, I worked in the EEO/AA unit of the state agency I am working in, and I learned so much from his speeches and trainings that I attended about the EEO/AA field. http://www.boardmanlawfirm.com/bios/GREGG.php
I also agree that using a couple of myths and misconceptions would be great in the course. I think the biggest myth is that AA is about quotas. Second biggest myth is that EEO doesn't apply to white guys.
Another idea is to include real life stories of people you know that if not for affirmative action laws and such they would have never escaped the continuing discrimination they endured. I have used a couple of these stories in trainings I've conducted. My mother-in-law worked in finace for a large national corporation back in the 1970's and because of a class action suit that had been filed by other females she was finally promoted to a supervisor position. A coworker I met about 10 years ago told me a story about how she worked for the Postal Service for 20 years and always had to train the new supervisors they hired for years and years. Male college graduates. She wasn't permitted to apply. Then as a result of a class action lawsuit, she was finally promoted to the supervisor position and was the first female supervisor of that type of mail processing center ever. My last supervisor, who is in her 50's told me about how when her mother was pregnant with her and applying for jobs they would ask her if she was pregnant (she wasn't even visibly showing yet at all), and when she answered Yes they told her to not bother applying. It happened every place she went.
I went to a training once and they showed a PBS video production about a high school. In the class, students took dna swabs (inside the cheek) and sent them off for DNA analysis. The kids were assigned to research their family history, if available, and try to guess whom else in the class they were most similar. When the DNA results came back the teacher reviewed them all and they were all completely suprised. The kids thought that because of similar skin color and other basic things they might be genetically similar, but the DNA showed much different. And the final point of it all was that we are all so much similar to each other than we are different - in a huge way. It was a completely different take on diversity and it certainly captured my attention. if you look at PBS online you might be able to find that video.
Sorry for such a long winded post! Hope this information helps!
