How do we make the impossible possible?

While the 21st century promises new tools and new ideas, there are many people who do not believe we can change education with technology. There is a threat to the potential of the 21st century tools rooted in the conservative nature of the public education institution. As many experts in the field of education technology know,  some school systems work against the use of technology through policy. In-service teachers and pre-service teachers often note, "it sounds good but I could never do that in my school". On September 23, Will Richardson challenged educators to change the way technology is viewed. Students left the lecture inspired but also frustrated because they either work in settings where the mindset of teachers does not favor technology or they observe environments that do not promote technology integration. Given this conflict, how do we prepare teachers to effectively use technology in environments that are not conducive to technology integration?
