Educating adults differs from educating children in several ways. One of the most important differences is that adults have accumulated knowledge and experience that can add or hinder the learning experience.

Educating adults differs from educating children in several ways. One of the most important differences is that adults have accumulated knowledge and experience that can add to or hinder the learning experience. Another difference is that most adult education is voluntary, therefore, the participants are generally better motivated.

Adults frequently apply their knowledge in a practical fashion to learn effectively. They must have a reasonable expectation that the knowledge recently gained will help them further their goals. One example, common in the 1990s, was the proliferation of computer training courses in which adults (not children or adolescents), most of whom were office workers, could enroll. These courses would teach basic use of the operating system or specific application software. Because the abstractions governing the user's interactions with a PC were so new, many people who had been working white-collar jobs for ten years or more eventually took such training courses, either at their own whim (to gain computer skills and thus earn higher pay) or at the behest of their managers.
