To compare different methods of accessing and presenting on-line help, controlled experiments were conducted. Several different help systems were compared, including a natural language help system and a human tutor. The results indicate that, while varying the help mechanism may have some effect on learning, its importance is greatly overshadowed by the simple quality of the help texts being presented. Even for on-line help, good writing seems to be the most important part of helping the user, far more important than elaborate or sophisticated mechanisms.
