Definitely. When I was in school we started to have projectors in classrooms but I honestly don't think they added much at all. Seeing a "modern" classroom with electronic whiteboards and tablets everywhere is horrifying.

I doubt any paedagogues were asking for this. What's more likely is Microsoft and Google realised there were education budgets all over the world they weren't yet harvesting.

Projectors and electronic whiteboards elevated lessons for me. Ever see a science teacher try to draw a galaxy or nebula on a blackboard, and try to describe the awesomeness of it using just words?

Math concepts, especially visualizations, become so much more accessible.

One math teacher in my school used an analog overhead projector as part of his workflow: he would write math on a long transparency roll, sitting at his desk, facing the class, so every student could see exactly how their work should be reasoned-about and laid out properly. He could rewind (literally) to any previous point in the lesson.

As always, it comes down to one's ability to use the tools effectively.
