At least from my experience being a student in the US, we kind of do that, but it is separate. I had quiet a few assignments where I had to give a presentation of some kind. Where we mess up with this, it usually works out that kids make power points full of information and just read off the slides. Of course, this practice isn't exclusive to students, I've seen many presentations in academia, my time in the military, at technical talks, etc that do just this, read off a power point.
