I routinely point out that we were far better off in the days of chalkboards and used textbooks - and it cost a whole lot less money.
Needless to say I don’t win many popularity contests with the local teachers and school board.
The unions prefer stupid children who are easily molded into slaves.
I note scores of unused “Smart Boards”. I teach adult level classes sometimes. The best tools are an overhead projector and a white board (much cleaner than a chalk board). Death by power point is efficient but nothing beats time spent giving and working examples but we often have to take that out in the interest of valuable time. Training takes people away from work and is expensive (forget trying to explain the value of training since all you hear from most managers is how much it costs)
Every class I have to teach a small section on how to do math with bracketed functions and the correct order of operations. I often provide an equation sheet and they still get the answers wrong and wail loudly about how it isn’t fair and how they aren’t engineers and this should be in an app or excel bla, bla, bla, bla.
