Parents also need to remember that home learning will be, and should be, taking less time than school based learning.
The videos etc are the teacher input. This is being done without distraction and without interruptions of questions from other children. There is no time being lost for coming in to the room, settling down, getting out equipment, This is usually a fairly small amount of a lesson. The rest is the children working on tasks with the teacher supporting those who need it, walking round the room, etc.
So a one hour school based lesson will be half that if done at home. Depending on the lesson content the teacher input part could be far less.
At infant level the times are reduced even more in Reception and often hear 1 there is a lot of free flow child led activity where the teacher and TA would be monitoring and making observations, joining in with play and asking the children questions. This simply can't be replicated with home learning. The teacher input in reception - the formal sit at the board and listen bit - is really a very small part of the school day, minimal some days. Even at key stage 1 it's no where near half the school day.
Just because your child is normally in school for 6-7 hours (with maybe 5 hours of lessons after taking off playtime and lunch, registration, and assemblies) a day they aren't sitting down listing to the teacher input for anywhere near that amount.
We are providing each day - English, maths and phonics sessions, produced by our own staff. We then post two other subject tasks a day, though these may not have been produced by our staff. Weekly we provide a PHSE lesson and also some intervention stuff - these go our generally though in school they'd be specific children. But there is so much of school we can't replicate into home learning.
