Hm, I don't think the problem lies within the use of technology, and more with the use teachers make of technology.
Many teachers tend to rely solely on PowerPoint presentations or transparencies to impart their classes, effectively turning such class into a boring monologue which consists on one person speaking (actually reading what it's projected on the screen), and a bunch of youngsters simply listening to that person for one or two hours straight (although they can read the projected materials faster than the teacher can explain them), which as you may conclude it's an awful way to transmit knowledge to your pupils (the common opinion in my degree is that the worst teachers we ever had are those using such methods). This ends up wasting everyone's time, yours and your pupils, which could be invested into more productive matters, like allowing the students to read the materials at home and trying to understand them on their own.
I supposed that in other countries and colleges with a longer tradition of using audiovisual media in class would no longer have such problems, as the mantra used by those in charge of designing each faculty plan of study which consists in: "use transparencies, presentations, and other media to support your classes" would have long netted an actual effect on teachers, but sadly it looks like it's not the case.
