Learning is a process that happens at moments and in spaces that go beyond those typically defined by formal educational institutions. In fact, it is widely recognized that learners' physical and social interactions with the "real world", outside the traditional classroom, cannot be neglected when promoting the acquisition of certain skills [Bruce 08]. For example, and within the context of formal education, a visit to a museum could be used for complementing in-classroom learning with situated activities in the "real world".
