How many weeks long is the session? My friends who teach at community college say they spend an equal amount of time working on preparation and grading as they spend it the classroom.
If he is given teaching material by the previous instructor this opportunity would be more attractive.
Thanks so much to all of you for your great suggestions. I’ll convey them to my son, but without mentioning that I posted about this on CC – which he has no idea I’m still on, let alone that I still ask advice about him here sometimes!
By the way, the clickers can be pre-identified so that you can tell if particular students are having trouble with concepts being presented and whether all are voting on question answers, etc.
Or there are websites that allow real-time polling. 
These were used them in some of the classes I took (those were only 2 hours long).
Heh, I took four 4 hour art classes over the summer last year (because I was crazy ).
All the teachers did a 10 minute break at the top of each hour. It’s grueling, and a lot of kids sleep through at least part of it.
The art history classes were more challenging than the studio classes because you were stuck in your seat. I’d recommend lots of getting up and moving around.
I taught summer classes during the day for man years. The classes were two hours long, 4 days a week. I always have a break after an hour.
IMO, your S should have a minimum of two breaks. He also needs to be creative in how to teach the class. Four hours of lecture would be torture for both him and the class. A combination of lecture with slides, group work/ assignments, group presentations,class discussions and debates.
He has work cut out for him. But congratulations to him for being offered the job!
You might try what I do…saying, “I have a friend who advised this”. I don’t have to say I posted it on CC. It’s not really lying, because everyone here is a friend, right? 
Of course when I try that with my husband, he says, “Oh, was that from someone on CC?”
Yea, D and H always suspect anything I learn that is from “friends” is from CC, especially if they weren’t present when I learned it.
Hahaha, I know. Many of us seem to have to explain why we are still on CC.
I’m not explaining nothin! Nobody ever asks, and if they did, I’d tell them to…(coming up with a few creative responses). :-*
My Mr. even asks me to ask my friends!!! Lol.
Anyway, forgot to say - congrats to your son, Donna!!
I took long summer classes in grad school and would agree with breaks every hour, otherwise people will interrupt him for bio-breaks. He can have a slightly longer 2nd break. People want to finish up and get home.
Thanks, morrismm and BunsenBurner.
I was on the phone with my son Friday night (we generally speak for an hour or so about every other night), and started to bring this subject up by saying something like, "So, I’ve been thinking about that class you’re going to teach this summer, and . . . " (I was planning to present all your great suggestions as the product of my own deep contemplation!) But he told me that although he’s accepted the offer, he doesn’t really want to talk about the details right now, because he’s trying to concentrate on finishing his Master’s coursework this spring, and he’ll focus on preparing for the course, which starts at the end of June or beginning of July, when that’s done. So I’ll save all your advice for later.
I did ask him how many people are going to be in the class, and he said it depends on how many people sign up for it – at least 5 are necessary to hold the class. So he has begun to “advertise” the class and to try to recruit for it among some undergraduates he liked who took the course he T.A.'d last year. (It was a 100-person class on “Art and Medicine,” taken mostly by freshmen and sophomores – a lot of them with no previous experience in studying art history – to satisfy their distribution requirements. So it was really quite a lot of work helping the students in review sessions learn how to “see” art and translate visual impressions into written words, and dealing with emails asking things like “how do I write an art history paper?” But he told me he enjoyed it quite a bit, although it took him a while at age 25 to get used to having all these 18 and 19-year olds addressing him as “Mr. L.” at first. I don’t think I’ll ever be able to imagine people perceiving him that way!)
I admit that I do worry a little bit about his being able to handle all the work necessary to prepare for and teach this class, and also to write his Master’s thesis – which he was planning to do this summer so he can apply to Ph.D. programs in the fall. (It’s going to end up taking him more than a year longer than the standard two years to get his Master’s degree, because he had some pretty severe depression issues one year, and ended up with a lot of incompletes that he now has to finish.) Plus he’s always had some problems with procrastination and time management.* But I’m not going to say a word about that to him, not only because he’s a 26-year old adult and it’s none of my business, but because I would never, ever want him to think, at any age, that I don’t believe in him. Which I do, very much.
