The attention given to teenage audience in museums began much later than that given to visitors of other age groups. It is often believed that teenagers are difficult to appeal to, that they do not account for a large percentage of museum visitors, and that they are in a transitory period which eventually leads to adulthood. Consequently, museums have been less willing to invest their resources in this difficult age group. Teenagers who successfully identify and integrate identity can smoothly transit to adulthood and museums by providing learning resources in free-choice learning environment can assist this process of discovery and integration. This article discusses museum educational programs for teenagers with examples from different museums. Challenges met by the National Palace Museum’s teenage programs will also be examined and analyzed.
