@mosquitofeast what about a secondary which provides extremely limited at home learning, no marking, no feedback?
Should a child be able to teach themselves French, maths, statistics, chemistry from a text book bought by a parent to plug the gaps?
My DC's secondary provided very good lessons when they were in school but the home learning provision in many subjects was somewhere between woeful and non existent. Feedback was lacking so in some cases they had no idea if they had done things right or wrong.
Before someone tells me I should have contacted the school, I did this and was told on multiple occasions that they were doing their best and that feedback was not to be expected.
It's just not possible for many young people to teach themselves from a book as you suggest.
Plus what about the passion that an excellent teacher injects into a lesson? An infectious passion which sparks a child's interest?
You are of course entitled to your opinion but in my own experience live teaching is a wonderful gift and text book or solo study is not a substitute for this.
