I can't see how anyone can say that a recorded lesson or written instructions online can be better than a live lesson?
Pre recorded lessons allow children, and parents, to complete the lessons at a time which suits them. For many working parents, especially in younger years, this is an essential element of remote learning.
Our pre recorded lessons were interactive with suitable pauses left, etc. We made them as interesting and engaging as we could. The accompanying activities complimented them and the daily regular, albeit short (the children are only 4-7 here after all) was useful for many.
However there is no way round the fact that remote teaching and learning for primary aged children almost always will require a supervising adult/parent. I'm not sure there is a way round that - even live lessons won't get round that issue,
In lockdown 1 we had full bubbles. Almost all teaching staff were working full time in classrooms. They were not necessarily teaching their normal classes, or on their normal]al classrooms or with their normal teams. When dealing with young children it simply isn't possible to teach live to the class and be broadcasting live to children remotely.
No one is saying that remote learning is better than in person face to face teaching. Just like for dh, his legal work is more effective when able to be done face to face in person. However, at present, we all have to adapt and provide as good as we can through difficult circumstances. That is the same for all work places and jobs, and for all us us regardless of age.
