In this paper we present a pilot study to improve the learning process on distance learning Engineering master's degrees. We propose an activity where the students individually produce a video in which they explain the solution to one of their assignments. They then receive the teacher's feedback and are acquainted with the assessment rubric. Finally, they produce a second version of the video, the assessment of which is the basis for their overall mark. The results of the study show that students improved their ability to give oral presentations.
