Excellent post that everyone should read! Robert Madden has done an excellent job of pointing out the obvious! When we use test scores as the reason to implement technology we jump on a bandwagon we may not want to be on. "Live by the sword, die by the sword." "Live by test scores, die by test scores."
We use technology because it is the medium of the 21st century. As for what and how that medium is used - that determines the outcome.
