This paper reports the results of a study designed to determine people's preferences for different types of Web-based educational activity. Researchers identified six activity types for comparison: Creative Play, Guided Tour, Interactive Reference, Puzzle/Mystery, Role-playing Story and Simulation. They collected two sets of data: 1) user exit surveys evaluating the study site and preferred genre or type of learning activity and 2) serve statistics indicating the duration of stay. Researchers found clear differences in preferences between adults and children.
