1. Leveling the playing field for all students. Erase the stigma of "The haves and have nots". Every student has the opportunity and the ability to experience and live true "anytime / anywhere' learning with access to the internet, applications, collaboration, self directed learning, etc......
I agree with Terrance about leveling the playing field. I also like the possibility of a student (and teacher) using the device to electronically document their work and progress throughout the day. Students can take pictures of their work, respond to individual check-ins from their teacher (or peers), journal and the teacher (and perhaps parent) can have access to everything. I'm mostly thinking out loud, but I think their is an opportunity there.
As we work to become facilitators of learning, it will be necessary for students to become more independent thinkers and learners. I can't think of a better way to access the vast resources of the internet, while allowing them to express their curriosity and find material that is truely engaging to them.
Higher ed is moving toward learning any time any where. With K-12 students following in that path, they will be totally acclimated to that way of learning and thinking by the time they reach college years.
