That's the wrong way to use technology in teaching. I've had several classes where the profs managed to use technology in a way that enhances the learning process instead of hindering it. My biochem class had lectures the old school way that you described, they gave assigned reading out of the book/supplementary materials that they provided and the prof would just go through his lectures making notes/drawing diagrams/etc. The difference was they did the notes on a tablet that was projected for everyone to see, and the lectures were recorded, voice, notes, student questions and all (camtasia is awesome). Surprisingly, they still had a very high attendance rate, and most people went to class and just listened to what was being said and thinking about it instead of focusing on writing down every little piece of info that was said, and took notes off of the recordings later.
Some of my other classes were taught by a couple profs who were collaborating with an education researcher on how to improve modern teaching. Everyone had a cheap little $5 remote that that was tied to a receiver that the profs had, and they would ask questions every 5-10 minutes in class to see how well the students were grasping the concepts and if they needed to go over anything again (even at a college level, there were still plenty of people who either thought they understood something when they didn't, or were just too shy to stop class to ask the prof to go over it again). Again, their lectures were pretty old school. They had a slideshow with the basic concepts they were going over, but did most of their teaching on a blackboard with chalk. I had other classes where the profs did pretty much what you described, and had a slideshow that they just read off. Those were the classes that I only went to for the test.
So to implement helpful technology, the profs don't have to change their teaching methods. They can add technology to their tried-and-true methods that help the students instead of just making a huge hassle for everyone involved with little benefit.
