NavEx: Providing Navigation Support for Adaptive Browsing of Annotated Code Examples

Abstract

This paper presents NavEx, an adaptive environment for accessing interactive programming examples. NavEx implements a specific kind of adaptive navigation support known as adaptive annotation. The classroom study of NavEx confirmed that adaptive navigation support can visibly increase student motivation to work with non-mandatory educational content. NavEx boosted the overall amount of work and the average length of a session. In addition, various features of NavEx were highly regarded by the students.
