Hello Alejandro. I think your question is something that we all ask ourselves. If sometimes in the actual classroom, it is hard to get the students attention anf to actually do their work, I can imagine how will it be whie being virtual classes. I work as a substitute and I will be figuring thatout myself. I will be asked to be in charge of a classroom virtually. I do not have any experience with it yet, but my goal is to keep students intertained and engaged at the same time. Act as if you were still in the classroom, the rules and expectations should be the same. Each class will be different so what works for one might not for another one. I would try to make the lesson fun and interesting for the students maybe with a fun activity as a reward for them at the end.
