When exploring these sites, our objective was twofold: (i) to confirm that they were suitable for the analysis because they met the criteria we had set for the corpus, and (ii) to put forward hypotheses about strategies of hypertextual wreading. Therefore, in our exploration of the sites, we followed usability criteria, that is, we drew our trajectories and built up our traversals (Lemke, 2003) as teachers and experts with a specific pedagogical objective in mind. This is the context which provided the specific framework for our heuristic descriptions.
