Iterative Learning:

Repeated use also enables users to become familiar with the
structure of the hypertext system and the significance of the
variable paths through the knowledge base.  As suggested in the
introduction to information management (Section 3.0), the path
choices presented to the user at each information node should be
perceived as parallel (representing a shared or common theme in
reference to the parent topic) and complete (representing a
comprehensive elaboration on the parent topic).  The exploration
of the system according to various navigational criteria can
enhance the user's understanding of the knowledge base as a
whole.  Additionally, by comprehending the implications of the
associative link structure, the user can gain an understanding of
the general knowledge base without literally navigating every
path in the system.  In other words, if structure is coherent and
comprehensible, users can begin to understand the context of
information areas that can be accessed with the selection of
paths defined by alternative nodal relationships.
