In what other field do we have to argue and justify the need for technology? You don't see baseball players saying "hmm, I don't know, these new bats let us swing faster and they break less, but maybe we shouldn't use them". Drivers aren't saying "wow, this car has six airbags and heated seats? No thanks, I like a dangerous ride and a chilly behind." I've never seen someone look at the new iPhone and say "you know what, let's just stick with the old processors; they've been good all this time." In education, however, we talk about technology like its this "other" thing that we have to integrate into our classroom. I would argue there's no such thing as "instructional technology" or "educational technology". There's simply teaching. You should be coming up with your ideas first, and then using technology to help support you...if you really need it. When I speak on Gamification, or hear people talk about Flipped Learning, the best presentations don't mention the tools and the tech at all...or if they do, they wait until the very end. Technology in education shouldn't even be a field, it's very existence means we're intentionally ignoring it's advances.
And in all honesty, technology doesn't just mean "computers". Everything invented after you were born is a new "technology". All the technology from before you were born...that's just called stuff. Even if we use the highest tech available to us now in Kindergarten classes, those students won't consider it a high-tech room. They'll just call is "school".
