Like Mark, I am going to connect two of my HUC 106 Public Speaking classes. However, I will be primarily using a wiki platform for my activities.
I like to use wikis because of their ease of use and simplicity in keeping everything (communication/comments/etc.) in a central location. The activities will consist primarily of peer review at a number of levels/stages. I haven't quite figured out how I will assess these activities but it shouldn't be too difficult to come up with some measures.
Basically, I will be grouping students into teams of 4 (2 from each class so they will have a known peer from within the class and 2 non-known peers from outside the class). All students will post their outlines for the informative and persuasive speech.
Peers will post their comments/feedback as to: topic selection (this is post obviously), organization/structure, and overall effectiveness of outline content. In-class peer will also provide feedback in the same wiki space on the actual speech itself (this will be delivery-based feedback).
The purpose it to get as many viewpoints/perspectives as possible, beyond the instructor's.
