The Internet seems an ideal medium for fostering and supporting informal adult learning because it allows adults to seek out and use resources independently, control the pace and direction of learning, and talk to and consult others. Because it provides access to information, encourages meaningful interaction with information or material, and brings people together, the Internet supports learning that is constructivist in nature and that builds on prior knowledge. Issues have been raised related to the Internet and its role in informal learning, including access; degree of control that governments or other agencies might exercise over information available through the Internet; incomplete understanding of the extent and type of learning that is occurring; skills needed to engage in self-directed learning on the Internet; motivation for those who use the Internet for informal learning; and how technology can be improved.
