There are several approaches a World Wide Web site designer considers in developing a menu structure. One consideration is the content of the menus (what choices are available to the user). Another consideration is the physical layout of the menu structure. The physical layout of a menu may be described as being one of at least three different types. The traditional hierarchical disappearing menu structure is used most often. Persistent menus, or menus which remain on the screen, often accomplished by the use of HTML tables or frames, is a second approach. A third approach is the use of graphic or textual maps that show the path taken to a particular document. The purpose of this study was to determine whether visitors who are just browsing can do so more effectively under one of the three menu schemas described above. The comparative inquiry of the three treatments used volunteer graduate and undergraduate subjects (n=44) from Indiana University Bloomington. There were no statistically significant differences among the three groups with respect to subjects' conceptual understanding of the structure of the Web site. (Contains 27 references.) (MES)
