I used this project to get my students to understand what life was like during the Great Depression. Obviously we had to discuss that computers didn't exist nor could people afford them, but they seemed to like the irony of it.
They also have to ensure that I can see the narrative arc of the Great Depression through their posts.
They create a twitter feed from the point of view of a person during the Great Depression. They have to make 30 tweets complete with hashtags. I actually allow them to do it by hand, but they get extra credit for actually creating the page.
