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. Advantages to authors include a wide audience, the opportunity for effective communication and prestige. CD-ROMs are less expensive to publish than books. Electronic seminars are not limited by attendance. An author can include sound, animation and digital video to improve communication of material.
