My SIL is practicing for live/recorded lessons now, has delivered one last week which she found awkward, it took ages to prepare but thinks now she has done one, with practice, she'll relax into it and won't need to prepare as much.
It was no video, presenting and talking through the slides/tasks she had already set, chat enabled for pupils to ask questions. Recorded for pupils who couldn't listen at the set time. She spent a little time setting out the code of conduct for them during online learning.
She refuses to listen to the lesson recording of herself as she knows she will think she sounds terrible and it will make her more nervous , but sent to me and I listened and it was very good for a first attempt. I could tell she was very nervous to begin with but by the end of the lesson she was getting right into to flow of it.
Previously she never did them because the choice was live lessons or give out slides/worksheets, so she and her colleagues refused to do live/recorded online lessons quoting many of the reasons above. The one teacher who had done some short recorded videos (of his hands writing/explaining some physics equations on a piece of paper) was told to stop so the rest of the teachers would not be challenged to do similar.
Now schools are heading back the choice is actually be in school more (which I dont envy any teacher as I think it's too soon) delivering the same short lessons to your split classes twice or 3 times, now live online lessons are more attractive.
In hindsight, now she has done one, she wishes they had bitten the bullet and started sooner so they would have been comfortable doing it and had proven it as an effective and viable option to negotiate with their ht instead of all the initial reasons they said they couldn't be done being discussed..
