Pour une sociohistoire de la pédagogie de 'alternance dans les maisons familiales rurales.

This article describes and analyzes from the point of view of their major evolutions, the purposes of the work-study training of ruralfamily houses, one of the main private institutions of technical agricultural education in France. This pedagogy of sandwich training comes from agricultural trade unionism which defined modes of intervention of training agents, called monitors. Sandwich training, initially built against public primary education, had the main goal of restoring peasant family as a legitimate educational body, considered to hold the monopoly on the transmission of agricultural knowledge. However, from the 1960s, this initial purpose disappeared. With school massification, work-study programs now play the role of a second-chance school oscillating between professionali%ation function and school remediation function. During a third period, identified from the 1990s, when the urban family homes were created, these two functions came together, as evidenced by the evolution of the role of monitor: he becomes a referent adult and a "tutor" for young people in difficulty preparing to enter adult life.
