Ipads in the Classroom: Do they really make a difference?

Article:  Less than a Class Set (December 2011/January 2012).  http://iwelearning.edublogs.org/files/2011/12/dec2011-iste-article-about-using-iPads-in-small-numbers-qxrko7.pdf

Summary:  This article discusses one of the hottest growing trends in instructional technology, the Ipad.  The article discusses how some teachers/classrooms are hesitant to use Ipads because they are costly and a classroom set is impossible to purchase.  The teacher goes on to discuss a case study where classrooms only had a few Ipads and were very successful.  The author notes one way to use the Ipads is to set up learning centers using other technologies or lessons.  Also, grouping students into pairs or trios promotes critical thinking while using apps.  The article also points out some rules for things you should do if you are only going to have access to a few Ipads versus a classroom set.   

Review:  This article is a really good one.  I know that I would not be able to purchase a classroom set of Ipads, but might be able to get access to 1-2.  I think that I could use the Ipad for things such as Google Earth and History Channel.  My students tend to work well in groups so I would be curious to see how it worked with the Ipad.  The only thing I worry about is how jealous they would get over time spent with the Ipad.
