Implementing a Constructivist Approach to Web Navigation support.

Abstract

Navigating the Web has its difficulties. If some of the user disorientation originates in the practical operations for navigation and is reduced when the browser provides a map of the visited space, we argue that the main difficulty arises with characterizing Web contents. We propose a new approach to Web navigation support coined "constructive navigation support". We present the main features of NESTOR, a browser implementing this approach and we discuss the results we obtained during a first experiment in the educational domain.
