Does the labeling of links assist user orientation?

摘要

Hypermedia learning material often makes broad use of links to information which goes beyond the learning objectives. But instead of being additionally motivated some students rather feel too much asked of. Within the Lilienthal project (www.pilotschool.net) links that don't follow the linear navigation are labeled with respect to their relevance for the learning objectives. First evaluations prove that the students welcome this assistance.
