I think the underlying thinking behind most educational technology is take the work out of the hands of the local practitioner, deskill the teacher.
I don't know if this is the intent, but it is certainly the (predictable) result.
I remember when my daughter was struggling with one of the New Math algorithms for subtraction. Naturally, I was only taught the traditional algorithm in elementary school, so my helping her was out of the question. As good fortune would have it, I had a parent-teacher conference scheduled with her math teacher the following morning, so my plan was to take 2 minutes and have the teacher demonstrate the new algorithm so that I might help my daughter with it.
Well, the teacher took several minutes just trying to contrive a subtraction problem that this specialized algorithm would apply to, and when she was unable to do so, she admitted in frustration that she doesn't understand the new algorithm either and that only the computer teaches that algorithm. I sat there with my jaw on the floor for what felt like an eternity and said not to worry about it and that I was sure I could find a YouTube to explain it.
So yes. What you say is true. The teachers are slowly but surely becoming little more than glorified exam proctors. It's pretty sad.
