I started out very basic, defined digital scrapbooking, types of software used in ds, what to do with you scrapbook pages, etc....I touched some on Digital Camera's, system requirements, etc....I put in about 80 hours of research to create my presentation, but on the plus side I only have to do it once.
I am assuming that all of my students have a pre-requisite of some computer knowledge, printing, etc.... But you know what happens when you assume

. This discussion does give me a great idea, I am going to state in my class description that all students should have a pre-requisite knowledge of Windows and printing. This should weed out the people whom have never touched a computer.
I has a large class with 20 people, I could have done more but the classroom size was perfect for 20. I also used a projectos that connects directly to my laptop so everyone can see what I am doing on my computer.
Well, hope this helps, you inputs certainly helped me.
