Private, 'Public' schools, certainly the ones my two children attended anyway, did not have enforcing discipline in anything like the way Mr Gove proposes. AOG, do you think if Public Schools followed Mr Gove's suggestions, they would be better?
As to academic improvement, the private schools have certain advantages. The classes are small, there is more time for teachers to deal with pupils as individuals, there is strong 'pastoral care' and a teacher is assigned to each pupil to that end, and in boarding schools the pupils are in a controlled environment all the time, free from outside and adverse influences. Plus, the parents want the children to have the best education; there is no risk of the parents not caring one way or the other, and, in general, the pupils are motivated already or given motivation. Replicate all that and troubled state schools would be better.
