NavEx (Navigation to Examples)


NavEx - Navigation to Examples - is a Web-based adaptive navigation tool for exploring programming examples. Serves as adaptive guidance shell for WebEx. Eextends traditional performance-based annotation . NavEx uses concept indexing of the examples and provides three types of information to students.

  • What examples the student is ready to browse and what s/he is not.
  • What is the student's current progress.
  • Whats examples are the most relevant for the student.
  • Progress of the student with relation to the group.
