The teaching unions have all said no to live video teaching from both a student and teacher safeguarding point of view. To explain further, there's the potential for teachers' images/voice/video to be manipulated, and that could potentially be career ending. Teachers also have children of their own and these could be exposed to risks. From the point of view of students, it's also a risk as very occasionally teachers will sexually exploit pupils, and it would be relatively easy to do this via video call.
I'm aware of a few private schools who are doing this but they are recording everything via the school's remote server. I know ours wouldn't cope with this.
Also, have you ever been on a video call with 30 people, not all of whom are co-operative?
Some schools are doing live chats via Teams or Google Classroom. I think in many ways this is a more responsive way of teaching as no-one's questions get missed and students can scroll back and find the relevant answer etc. Work can also be easily submitted and corrected via Teams. Everything is in writing, so there is less of a safeguarding risk or potential for allegations to be made. However, Teams is getting quite creaky at the moment, and this does rely on every pupil being able to get online at a set time. There are also some pupils who really struggle with the tech side of this- it works best if you have set it up in class in advance.
Another issue with live teaching is that those teachers who are in school looking after key worker children can't do it- should their classes miss out?
Other schools are setting work using an app like Show My Homework, and responding to questions via email etc. This works well for children who can't all get online at a set time- they can complete the work at their own pace and then email it to the teacher for feedback- they can also email the teacher questions throughout the day. This is probably not the most effective method of teaching BUT it is probably the most accessible for many pupils. You can set work which can be completed with a smart phone and pen/paper. Setting effective work this way requires lots of changes to planning, and so the teachers will also be planning whilst dealing with queries.
It's very clear from when I'm getting work submitted, a lot of my students are completing work at odd times of day. It might just be because this suits them, but I also suspect some are sharing laptops or having to do childcare at other times.
Also, I have had enough difficulty getting them logged into seneca without being able to talk through it in class. Getting them onto teams or zoom would be a whole other challenge.
Perhaps if BoJo had been honest, and given us a few weeks to prepare, we could have got classes really set up for remote learning?
I also think that as the situation progresses, any system that relies on one teacher per class will inevitably start to struggle.
