This article presents the results obtained in a training experience to improve the self-perception of digital skills of a group of Italian teachers. For its implementation a training in b-learning mode has been designed using free tools that teachers can implement in the classroom. The course saw the participation of 12 teachers from a secondary school in Livorno and the results were very positive as they all had an improvement. The planning, not only focusing on the technological tools, but especially taking into account the activities that would have been carried out in the classroom, is one of the keys to the success of this type of proposal that could also have a positive impact on the pupils. In fact, after the implementation of this training, teachers have in their hands all the tools to be able to activate the virtual classrooms and teach their subject at a distance.
