Educational technology, to me, is something that was originally intended to supplement the way teachers teach and increase productivity while easing stress on both students and teachers alike. What I'm seeing now, is that educational technology isn't just an add on to our daily lives, but is changing how we teach, how we learn and how we perceive education as a whole. When Postman speaks of how technology has winners and losers, I can see this play out in our own classrooms. After teaching through a pandemic, in person, online, and in a hybrid model, the gap between the haves and have nots has been magnified. The online portion of school was easy for some because they didn't have to stagger times to share devices with siblings, nor did they have to worry about wifi speed etc., but the ones who struggled, really struggled. From ones who were not intrinsically motivated to work to others who didn't have access to devices, wifi or lacked the technological wherewithal, the gap was (is) large.
I do see the value of edtech in our world, in fact, I don't know how we would have dealt with this pandemic if we didn't have access to some of these things, but I also believe that it amplifies the privilege of some while slowing the progress of others.
If I think back to my early years of teaching, I wouldn't have though about the development of edtech, but I didn't have to. If you weren't teaching keyboarding or computer science, you didn't really need to be in a computer lab. Now, access to computer labs, laptops and laptops carts are at a premium because more teachers and students see the value in working with technology, if only our school board felt the same and kept the supply up with the demand.
