Seeking user training techniques

Hi all,

I need to give end user training on information security. I usually 
have a powerPoint presentation with text, some posters, a few 
cartoons if applicable etc. I show the occasional movie. Also, I make 
the audience participate by asking questions and keeping the session 
interactive. The users like it but many a time once they are out of 
the class room they tend to slip back into some of their bad  old 
ways.

I have been thinking about including some games or simulation 
exercises in the training to re-enforce the material that has been 
taught. Does any one have any ideas on what I could include? Are 
there any resources that I could look up in this regard?  I would 
like the entire class to participate.
Note:
I realize that management has to enforce security policies and that 
training alone cannot lead to a behavior change. I am trying to 
increase the effectiveness of my training.
