Young children bring a wide repertoire of visitor behaviours to traditional art museums, using their minds, senses, and bodies to respond to and interpret artworks. When given opportunities for self-expression, choice, and control during an art museum visit, children are empowered in this environment. Allowing children to take a leading role as tour guides for their peers or adult partners is one way to engender such empowerment. This kind of experience shows them they have a valuable contribution to make and allows them to learn actively from artworks, through self-directed inquiry. This article outlines a number of art museum programs that have encouraged children as guides during school and family visits, and discusses the benefits of these programs--for both the children and their adult companions. The author also notes the importance of a supportive, responsive adult, who can extend children's conversations to introduce the language and concepts of the visual arts during child-led tours.
