At Des we have been using Microsoft teams since the start of the pandemic due to Covid-19. During the school closures the past 2 years we were able to stay fully in touch with our students as we held synchronous lessons and we followed the whole timetable as if we were at school.
Even now we are using Microsoft Teams in our classrooms when we have active cases in our class. Teachers have their lessons in class and design parallel activities for those students that stay at home because they themselves are active cases or students that were sitting close to them need to stay at home.
