This article begins by posing the question "How might the educational potential of the city be enhanced for children today?" The author suggests that one way to learn from the city is to travel about within it. Using research done in Boston into children's environmental use, knowledge and experience, the author argues that pilot studies are needed to test strategies to improve children's knowledge and use of their cities. Emphasis is placed on increasing children's ability to use maps in city travel and exploration. Tips are offered for making effective maps for children, including taking into account preferences for pictorial rather than verbal information. The research method is not specifically described, but references are made to map exercises, and interviews conducted with children and parents.
