The push for ubiquitous computing (UC) relies on an understandable and well-intentioned belief that teaching and schooling need to be transformed. This view appears credible based on large-scale criteria, such as test scores relative to other countries, drop-out rates, and economic changes. And the use of technology to achieve this goal is attractive, given the dramatic advances that have recently taken place. But the history of our schools tells us that reform that ignores teachers' views doesn't work. Teachers need to buy in if sustainable change is going to happen in classrooms. Veteran teachers often initiate rookies by telling them to ignore the newest educational fad because whatever they are already doing will come back in fashion soon enough.
