The national curriculum has broken down because academies can set their own curriculum. Having no curriculum in the 80s meant that I did one period of history several times over due to moving schools. However given Gove's grammar, times tables, poetry recitation and teaching history in chronological order the distintegration of the national curriculum may be no bad thing. Children need to be interested in what they do - let them write a story and then go through each sentence and ask them to correct the grammar or teach them a foreign language and then they will see why they need grammar and learn it as they go along. Let them use their times tables to work out whether they are being cheated by special offers in shops Find the periods of history interesting to young children. Also teaching this way children can find their own level and you don't get one extreme being completely lost and at the other end being completely bored
One of my exams the teacher did not follow the syllabus closely and I did worse in it than expected but its the only subject where I remember everything the teacher taught us and it has influenced my thinking to this day.
Teacher subject specialisms are also breaking down as school are finding it harder to find teachers or afford teachers.
Whenever the government reduces taxes overall and particularly for the rich they are transferring funds from state to private schools. Most children who go to private schools already have very privileged backgrounds so this is deeply wrong. However to understand this moral position this one probably needs a high EQ rather than IQ unfortunately.
