Silver Spoon -
I am SO bummed you're in California! Your classes sound great, and it's reasonably priced.
I'D like to take them--especially the dancing!
YES - These types of classes are needed!!!
Most people from my generation (40's) have NO concept of this kind of thing for themselves, unless they were raised by an older generation (my parents were born in the 1920's and as a result I benefitted from that). And younger parents? For the most part they're clueless (I know, I'm stereotyping). It's easily seen in the behavior of their kids. My older son (11 years) benefitted from my parents influence, and as a result he's very comfortable with being polite, behaving appropriately in public and greetings and small talk with adults. His younger sister, alas, came along after my parents died, and I admittedly am not as good as they were at being consistant with practicing the public behavior thing. I think the reason most people, let alone kids, are leery of the etiquette thing is because it really isn't "the norm" any more. The funny thing is once you know how to conduct yourself, you realize it's really not a big deal. It gives you so much self-confidence and helps you help others feel comfortable.
I taught in Japan for a while, and part of my job involved teaching "life skills" to my adult students. Luckily for my students dancing was NOT part of my curriclum!
You'd definitely have to change your marketing for the kid/parent crowd. Unfortunately things like this are hard to do as electives UNLESS there's some sort of reward at the end. I could see kids signing up for this, especially in upper grades, if they'd get some sort of boost to their average. The trick I'd think, is getting the potential participants to realize it's not a drudgery and once you know it you have such a great edge over your average Joe. I'm thinking getting the parents WITH the kids would be a great idea. Believe me, I know plenty of parents who wuld benefit from this more than their kids would!
My son can make my crazed at times, but he knows his manners and knows how to behave in public--it's amazing how little things can make your life so much easier. We don't make a big deal out of it, and he's certainly no Eddie Haskell (am I dating myself?), but I admit I take great pride when adults complement him, and I know he likes it too.
