This site has got some great articles on intergrating technology in the classroom. This one in particular gives some useful tips when setting up your classroom instruction.

This is a great example of using computers and technology to create differentiated learning within one classroom.

I think this article is interesting because we have to keep in mind the importance of what we are requesting a student to use the technology for. Important quote from the article "So I say to my students, 'If you wouldn't give a worksheet to teach this concept, why on earth would you give them an electronic worksheet?' Technology should be providing an experience that children would not get otherwise, to add a new dimension to their understanding"
