My question would be why Zoom didn't work. I am not a full time O and M person but I have shown people basic cane technique and certainly that is better done in person, although it would be massively massively better to fudge up some sort of solution online rather than not do it at all.

If I had to I would try to show the parent how to do it via zoom or whatever, then help out with them passing that on to their kids. I have done that in person because I can't be at their place every night after school, and I think it could be done via zoom.

It depends how old the kids are but at any point from early teens, even before that if they're bright, I would certainly expect them to start getting acquainted with screenreaders and computers and eventually things like zoom, under supervision. They're going to need that and it is better started early. If they really can't cope then the first priority is to get them coping with that.

Either way basically the approach is for you and your kids to both be on this zoom call and for the teacher to show stuff you can pass on to your kids. Your kids should be totally involved in it and as much of it as possible should be done in a way that doesn't have to involve you.

Of course it's not ideal and it's going to soak up a lot of time and effort but if that's what it takes, so be it. What you can't do is have no O and M going on for 14 months, that is not an okay thing for them to do to you.

Hello! My schooling this year was also completely virtual, and one of the first things I learned how to do was use a screen reader to access Zoom. It's not too hard, and there are only a few commands you need to know. I can offer more detailed info if you are interested (and it doesn't really take prior screen reader knowledge or fancy equipment). Just let me know.

Second, if your school allows it, try using phone calls if in person services aren't available (or even FaceTime. I use it a lot of the time when asking friends to describe things to me).

A second alternative to in-person services would be to send material to the student that can be discussed over a virtual connection. For instance, I was learning how to read music Braille this year, so my teacher would braille out the lessons for a particular week and send them home (my district had a specific location for picking up printed materials from teachers) and then we would use the lessons during our sessions. This isn't a perfect system, since it won't work for everything, but it does help.

The final option would be to ask if you can have your lessons before or after school hours, or at a time where the parent will be home so they can help the student physically while the TVI instructs virtually.

I know that wasn't you original question, and I apologize, but hopefully this info can help you or someone else!
