We all know what DDI means, as we have used it at school because of pandemic problems. DDI implies the integration of face-to-face lessons with distance lessons.
Students go to school for a set number of hours per week (which vary from institution to institution). In the remaining hours, however, they follow the lessons from home, at a distance. The digital platforms that are used to guarantee pupils a didactic continuity, despite the impossibility of going to school, are many: Google Meet, Google Classroom, Microsoft Teams.
Audio conference is another mode where pupils and the teacher connect via digital platforms in the same way as videoconferences but they only transfer audio. It allows direct communication but students cannot see the teacher and / or the teaching material. It requires less data transfer than videoconferencing and allows the management of large classes even without dedicated servers. This mode is often used for vocal (diction, acting, singing) or Video recording. In this way, the teacher records and edits his lessons and then distributes them to students electronically (email, dedicated platforms). The lessons can be downloaded and watched at any time and the quality of the lesson depends solely on the teacher’s equipment (pupils do not need microphones and webcams). It does not allow direct communication between pupils and teacher and requires more initial work on the part of the teacher.
