Imagine this scene, teachers:
You have a colleague down the hall who has been telling you all about this great new educational technology that she has been using in her classroom to amazing results. The kids are so motivated and engaged, and they are so enthusiastic about their learning. "You should try it too," your colleague encourages you.
So, you start to plan a lesson. How hard can it be? Your colleague makes is sound like the kids can just sort of dive right in and go with it. And, hey, your students are "digital natives," right? Shouldn't be a problem for them.
As your lesson rolls out, things aren't going quite so smoothly. A hand goes up, calling you over to help out. Then another hand, and another. While you are looking over one kid's shoulder at his screen, you realize that half the class is currently "stuck," and waiting for help. They start whispering to each other...
"I'm so confused!"
"Why are we doing this?"
"I'm frustrated..."
"This is dumb."
...And about that time you decide you are never doing this again. What a waste of your time--and theirs! Why did you put yourself through this anyway?

People who know me well--and my proclivities to experiment in my teaching practice, and my love of all things techie--might be surprised to hear that I am describing myself in this story.
