This article studies the issue of teacher training and digital university pedagogy. We present two in-service teacher training devices, articulating face-to-face and distant training, which have been set up during several years in France. The first one, Pairform@nce, concerns primary and secondary school teachers; the second, FoDESIT, addresses university teachers. Drawing on the study of these devices, we identify crucial facts, and questions, about the training of teachers at university, in particular: the possibility (or not) of up-scaling, using digital networking means; the quality of resources designed for, and by, the trainings; the link between educational research and training.
