As a tutor, it is very helpful to have responses from students during the tutorial.
A few students in recent tutorials have put on their cameras and it is good to see them. Many students say how my having my camera on helps them to feel more part of the group and reminds them that they are being engaged with in real time. However, I recognise that there are good reasons why some students might not want their cameras on.
It is good to hear students' voices, at least at the beginning of the tutorial and I do think this also makes everyone feel that we are involved in a collective endeavour. However, much academic work is done in a written format and use of the text chat option seems reasonable for many tutorials. It is also quite advantageous in that many people can post at the same time.
What can be difficult to teach with is when students do not give any kind of feedback/response during a tutorial. This means that the tutor is not clear whether the students are following or whether what is being discussed is too basic. Just a few comments in the text box or empjis are much appreciated by tutors.
