| Only within the last few years have we replaced | overheads and transparencies with 'smart boards' | and projectors and even then, few teachers have | been found to use them in any manner other than | an even more LIMITED version of the traditional | overhead. Back in 2001, my university microeconomics course was delivered via overhead transparencies (rather than Powerpoint like most other classes). But even the usage of transparencies was too much for this professor. All of his 'slides' were just transparencies which he had used a wet-erase marker to write dense paragraphs of text, which was mostly what he was reading back to us. Not only was this worse than most usage of PowerPoint that people complain about, he didn't even take the time to maybe type up these 'slides' and print them on transparencies (or go to a local office supply store / print shop to get it done). Point being some people will use the tools presented to them (even very basic tools) in the most bone-headed way possible. It's just a fact of life.
