As technologies mature, they tend to become easier to use. Take the elevator, for example. Another good example of the way technologies mature and become easier to use is the radio. When first developed, this tool was the domain of specialists, requiring expertise and patience to operate. Today's radio is a model of usability, requiring no special training in order to obtain today's Power Top Ten.
Teens use radio constantly without ever having had to obtain a certificate.
Now it is true that not all technologies are easy to use. For example, one would expect someone operating a nuclear reactor to have some expertise in the subject matter. If a technology is to become widespread, it is crucial that it be easy to use, so easy that an operating manual is not needed. A learning simulation, a conferencing tool, and a student record keeper should be as easy to use as a television, a telephone and a notebook. We must question whether our time and money spent teaching teachers to operate today's clumsy technology is time and money well spent.
