Access to computers is becoming less of a problem. Authors must make special effort to target a wide variety of computers and help inexperienced users. Most computer software titles are very expensive. Software versions of printed books often cost more than the printed version. Navigation can be a major problem in educational software.
Many titles are like mazes.
It is difficult to know their location within the program and difficult to know which options are available. Authors must make special effort to build useful navigation features. Educational multimedia software is frequently of limited use for reference. Most titles are tutorials at best. Authors also must support user-directed access.
