The way forward for a comprehensive education for every child is shown in this TedTalk video.
It leads to individual excellence for all pupils by introducing pupil/student centred learning. Students are free to learn a subject at a pace that suits each one. It also increases the teacher’s time by eliminating bureaucracy/paperwork and allowing them more time to teach their class on a one to one basis.
But watch the video. It gives much better explanation than I can here. There is no need for grammar schools, academies or free schools and reduce the need for Ofsted inspections.
