The idea of competences is that they are based on identifiable skills or capacities, and hence are not rooted in a body of content but rather in a student’s personal growth. (Karampiperis, Demetrios, & Demetrios, 2006) As such, students are able to select their own track or achievement path through a competence domain, as informed by their own interests, employer needs, or in the case of younger students, parental guidance. Each competence, meanwhile, corresponds to a selection of learning resources (and specifically, learning objects). (de-Marcos, Pages, Martinez, & Gutierrez, 2007*)
