Really interesting article, Jennie. I think it touches on the vital idea that computers don't change teaching, and that a whole new approach in education is needed if districts/states wish to get their money out of their investment. Good ol' Larry Cuban keeping everybody honest :)
There are now a large number of initiatives designed to make laptops with wireless connectivity available to all students in schools. This paper synthesizes findings from research and evaluation studies that analyzed implementation and effects of one-to-one initiatives from a range of countries. Factors related to successful implementation reported in the research include extensive teacher professional development, access to technical support, and positive teacher attitudes toward student technology use. Outcome studies with rigorous designs are few, but those studies that did measure outcomes consistently reported positive effects on technology use, technology literacy, and writing skills.
