Policy Issues largest challenges for integrating technology into classrooms

There are these three interdependent aspects of technology -- devices, markets, policy. We have wonderful devices that do all sorts of things that could make teaching and learning better, more exciting, closer to the devices that children already have. There are markets for these devices -- teachers, students, schools that would like to buy these devices to help with teaching and learning; there are likewise tons of sellers of products and services. There are policies that govern and "control" how these devices can be used and for what purpose. By and large, we were reminded by teachers and administrators at eTech Ohio that district wide and school level policies ban devices from the school grounds. Sometimes cell phones and iPods are allowable in schools before classes, but must be in lockers after school starts. Some places ban phones and iPods from lockers too. Most everywhere the most powerful and student-friendly devices -- portable computing (cell phones, lap tops, iPhones) and iPods are confiscated if seen or heard.
These policies are well intentioned and in service of trying to protect students from unwanted content and constant distraction. Sites are blocked in schools because there is inappropriate content lurking next to excellent content (YouTube, iTunes. Some of the most widely used sites on the internet like Wikipedia are banned from schools because they are open content controlled rather than editorial board controlled. These policies are well intentioned but they miss what is happening in the world around us and our students. These devices will only be replaced with yet more dazzling goo. What I'm hoping for is that educators will rise up and propose and use new policies that are appropriate for this new era of learning.
The policy on cell phones that I really like is: Have students place their cell phones on their desks in full view of everyone. Try and incorporate the cell phone into as many lessons as possible. Have the class discuss and write a policy for the appropriate use for cellphones in your class. Have the class collaboratively write a policy for appropriate use and the consequences for inappropriate use. Have students help in "in-forcing" the rules. A classroom up approach is needed in my view.
