Back before the computer age, there was classrooms via TV. If I remember correctly, some colleges and high schools had classes aired on PBS on certain days at certain times. These were for people who could not physically attend class, or who needed to continue their schooling during the summer while having to hold down a job.
The student ordered their book and class supplies from the college.
The student signed up for the tele-courses at the school or college.
The student followed the lessons and instructions on the pre-recorded tele-courses.
The student filled out the necessary documents and paperwork for the lesson and mailed it in to the school/college.
Not that difficult to do.
Pre-recording lessons by having certified, professional teachers follow curriculum has been done before, and can be done again.
Having pre-recorded lessons cuts out a lot of the BS, lies, and personal opinions from schools and teachers, as the lessons are basically instructors following the book or books they are supposed to use in that class.
Finished homework by students can be done on the computer, and either e-mailed in to the school, or printed out and mailed.
It's not a difficult premise, and is much more manageable than live classes taught by idiots that know nothing or only want to teach their own version of whats going on.
It really doesn't matter that much is classes are telecast live, or recorded and re-broadcast. The main thing is having the teachers know that they are nit teaching clandestinely, in secret, and they will be accountable for what they say.
I would prefer that classes be live, to avoid the possibility of recordings being doctored, or conveniently "lost".
With regard to live recordings, when I was a college student, everyone in my class has a tape recorder, taping the lesson live, so as to fill in the blank spaces in the notebook pages. I found them to be extremely helpful.
When I was a college teacher, my students taped my classes, and did not mind it one bit. Thought nothing of it.
