"Take a quick look in schools, and you will see that there are a great deal of "missed opportunities." You are still likely to see students sitting in rows, teachers at the front of the room lecturing, or students flipping pages in a textbook and answering questions at the end of chapters. This is happening, while across the room sits four or five desktop computers, fully wired to the world. Or, safely tucked away in many of the students' pockets are smartphones with more computing power than the first PCs many of us owned. These missed opportunities exist for lots of reasons. Failure to provide training and support for implementation. Lack of technical support for the devices. Leadership that discourages innovation and experimentation. The list is endless. Nonetheless, these are missed opportunities for engaging students in authentic, 21st century learning."
