I've taught technical and non-technical courses, both computer-based and lecture-based and I find computers are fine for reinforcing specific ideas, or for research, but for most learners other forms of learning are required. There are 3 general learning methods: Visual, Auditory, and Kinestetic (hands on) and most people are a combination of 2 or more methods. Computer training is mostly visual, very little hands on. The more methods that the teaching encompasses the more effective the learning will be. Personally I'm mostly visual and hands on, I like to take things apart to understand them; books on tape put me to sleep.
