Hello,
Yes, I believe so. I know that a good number of teachers use it - including my cousin in France.
I am not 100% sure how they implement that though. I saw some tutorials on youtube of teachers showing how to prepare a course.
I have been thinking for a while about making a special modules for teachers to handle students and share models privately. If I find the time one day, I'll work on that with the help of my cousin to define the requirements.
