The implementation of the EHEA has produced a change in the structure of university education, which urges professors to change their lecture methodology from master lectures to methodologies by which students become protagonist of their own learning, that facilitate their autonomy and teaches them how to learn to learn. This implies that currently B-Learning and E-Learning are favored, which leads to the creation of virtual spaces and a flexible education that allows students to work from home without having to travel to the university.

In order to make toxicology’s teaching more flexible, a screencasting application has been used, which allows teachers to record and upload the classes taught into a virtual platform and share the audio and materials used with the students. This makes it easy for students to review the notes taken in class at any time; it also helps students who have not attended the class to access the contents of the course, given that students face a workload in many cases. Most students often overlap subjects in the hours of theory and practices which makes it impossible to attend classes even if they want. On other occasions, students have to work to pay for their studies, which makes it difficult for them to attend classes, or they may find it unprofitable to go to the university for only one class. On other occasions, although students have attended the class, they might not have understood certain concepts well; in these cases, access, not only to the presentation of the class in the virtual campus, as it usually happens, but access to the presentation with the audio of the explanation given by the Professor, with the use of a screecasting application, allows improvement of students’ knowledge and improves the flexibility, which will lead to an improvement of the results.

From the experience carried out, it can been concluded that facilitating access to content for students and making learning more flexible leads to an improvement in students' academic results. Likewise, it has been proven that the students have a favorable view of the methodology used.
