The effectiveness of a Navigation Agent has been evaluated, which determines a path through course material tailored to the individual student. Lesson selection by the agent showed an advantage for students who were unable to monitor their own learning process. Initiative by the agent - where the agent also chooses the moment for selecting another lesson - reduced the time needed to finish the task by stimulating the students to study the lessons in a balanced way. The experiment also provides evidence that a mixed locus of control is preferable to either the student or the agent exclusively taking the initiative and selecting lessons.
