The Maisons Familiales Rurales conduct vocational training by work-linked learning. More recently, they have been using distance learning methods. The training systems are then described as hybrid (Lebrun et al., 2014) and alternating (Boudjaoui and Leclercq, 2014). The research focuses on the connections to the self, to others and to worlds (Bolle de Bal, 2003) experienced by trainees within these devices. Thus, we sought to identify which resources and factors could participate in the creation of linkage/unlinkage capacities. These connections are considered to be the combination of processes, structures and links that a person establishes between him/herself and the different instances of his/her person (personal or self-connection), between him/herself and others (social or other-connection), between him/herself and the social-cultural environments in which he/she participates (world-connection) (Bluteau, 2022). The research carried out explores the ability to link/unlink, understood as the ability to link/unlink within the hybrid work-linked training schemes studied. It is based on two adult vocational training systems and uses a qualitative methodology for collecting and processing data. The corpus, made up of interviews with work-study students who have experienced these schemes, is subject to thematic and lexical qualitative processing. The analysis of the results, using the capability framework (Fernagu, 2018a), highlights the resources and conversion factors identified in the processes, structures and links to the self, to others and to the worlds constructed by the work-study students in the systems studied. Indeed, we note that activities favouring the interface between the experiences lived in the different time spaces prove to be particularly conducive to the construction of links. The part of the self and the part of the other are thus revealed as two sides of the development process of the person.
