Not sure if your class and workshop has already taken place, @astardrifter, but wanted to share my thoughts on your question.
Art history is a very large topic. Perhaps the best way to present is to provide a survey of the major periods, from Pre-historic to Modern, and include representative slides of the classics and a couple, small amount of fringe. Slides that have a w0w factor would generate interest, and a brief survey after the workshop would help with what comes next.
Wishing you success.

As a fine art major, I would certainly take the class. I think Impressionism has enough variety to keep people interested. Good luck! What a great opportunity.

Sorry, but no, I wouldn't do the course, and while I can appreciate some art, a little I have no preferences.

I would, and the period would be the Renaissance (including both the High Renaissance and the Northern Renaissance). That would pretty much include everyone from Raphael to Bosch. In fact, just concentrating on one of these two artists for a one day workshop would not be enough time to do justice to either, but it would be a great way to spend a day.

Who is the target audience? Young children? Teens? Young adults? Retirees?
What are the local items of historical artistic interest?
What would a walking tour in your town look like?
I have always enjoyed the art in the ordinary. Why does a $20 bill look like it does? What about the columns at the post office? A walking tour of a cemetery, with a focus on the sculpture.

1. Yes, absolutely, with relish and excitement.

2. Van Gogh, Cubism, Picasso, Futurism, Surrealism, Dali, Dada, Mondrian, Pollock, Warhol, Pop art...anything weird, envelope-pushing, boundary-breaking, iconoclastic, controversial. The more controversy the better. I like weird stuff, stuff that's hard to understand, unsettling, provocative. Make it hard for me. Upset me. That's what art is for.

Yes, absolutely. Impressionist period. I love to go to the Art Institute in Chicago and view the amazing galleries of impressionist paintings. one of my favorite spots in Chicago.

Start with the theme: Art reveals the culture. Then pick a few periods of history and show what the art reveals about the culture.

OMG -- You must have read "The Secret"!!! That's so cool how that works!

It is really cool that you got asked to do that.

If it were free and a friend wanted me to go, I would go, enthusiastically. I'm sure I'd learn something.

I would choose pen and ink. It's amazing to me. In fact, I need to find something pen an ink for my mostly bare walls, now that I think about it.

1. Yes. 2. I like Paris Modernism of late 19th Century of course. I have the opportunity during a Summer humanities course to teach the class one day about plastic arts in the Renaissance, teacher was satisfied, my student mates were satisfied. I had just changed my major from Physical Education to Art History. So in the final exam there was a question of describing plastic arts in the Renaissance I got so involved on painting and sculpture that forgot to describe architecture, teacher didn't penalized me, because she knew I knew it. I think that was cool if not fair for everyone from her, but that is what humanities is all about.... Sometimes is not the Results what is Important. Your question is one of the best ever posted here. Thank You for the Memories. Modigliani fan but he is just one of many. Seurat, Renoir, Manet, Lautrec, Van Gogh, Matisse, Gauguin, Dali, Picasso, Miro, Rembrandt, DelaCroix, Velasquez, Goya, Vermeer, Rubens, Durer etc, etc, etc.

I might take it if it were a half-day. I would be more open to 20th century because I understand that the least.

I think it would be great..
I would try to make it more of a freestyle, whatever they were inclined to do.
