From Campus Technology:
Oklahoma State University plans to run an Apple iPad project during the fall 2010 semester to research the use of the tablet device in a classroom setting. The initiative will integrate the iPad into classes led by two faculty members, one in the school of journalism and broadcasting and the other in the school of business. The experiment will involve about 125 students at two campuses, the main campus in Stillwater and the other in Tulsa. Each class will integrate the iPad differently but will focus on specific measurable outcomes.
More details in the article. It looks as if some hard data may come out of this.
