Teaching in basic university courses is an essential part of teaching in an experimental degree. These classes introduce students to basic applied subjects, frequently accompanied by laboratory practices that are designed to be as formative as possible. The implementation of the flipped classroom, which uses explanatory videos to teach specific content and serves as a script for laboratory activities, has represented a considerable improvement over the traditional teaching methodology. The teacher's task evolves and stops being merely explanatory to become formative. In this development of pedagogical teaching techniques, we have further refined our approach by developing a series of videos in the form of learning objects with a dual objective: on the one hand, to reinforce concepts and content in class; and on the other, to facilitate student learning by developing complementary work related to the subject content. These supplementary materials are designed to assist students in the use of manuals, comprehension of phenomena, and, in essence, in promoting their self-learning.
