While reflexivity is seen as a not-to-be-missed concept in professional training, references to design pedagogical devices to enhance actors’ reflective capacities on their professional situations and to foster their professional and personal development are scarce and embedded in a patchwork of theoretical and practical approaches. As designers of such devices in agricultural higher education, our practical experiences, theoretical background and discussions led us to build a model of reflexivity as five intertwined key dimensions. These dimensions deal with aspects of reflexivity (...) that it is possible to work on directly with learners by using appropriate scaffolding methods, which we describe and illustrate in this paper, referring to our teaching experiences. Two dimensions of the model are particularly relevant for people who are not familiar with reflexivity, and sometimes reluctant to practice it. (shrink)
