Andrew Zucker has a great article at Stanford School of Ed's recent newsletter on Education technologies.  Part of his new book.

It's interesting how he compared schools to other organizations whose main business is information (like Google, Accenture, etc.).  His reasons to use technology include:

(1) We need to transform American schools into higher-performing
organizations, whether or not we use technology; (2) Digital technology
provides a powerful toolkit, offering unique advantages (such as
bridging time and distance, democratizing access to information and
services, and leveraging exponential increases in computer power) that
have helped transform other organizations, especially those based on
information and knowledge; and (3) Many schools already use technology
in smart ways to support education goals.

He sees technology as helping increase relevance and engagement with students, not only test scores.  He sees it as helping to retain and attract high-quality teachers. He also mentions clickers near the end.

In a sense, this debate is not really a debate.  Of course we need to use technology in schools.  This is a given because it will happen whether or not we want it to be there.  The question is how.  That's up to teachers, researchers, scientists, administrators, and students.  Just as a company like Google needs to use technology to operate effectively.  The key difference here is that schools are not private and their bottom line is not efficiency, it's the learning of children.  So we have to use technology in ways that improves THAT bottom line - not an easy feat.
