You may want to have a look at the concept of Free/Modern/Libertarian schools, as a Libertarian Communist, I would advocate this approach to education. An example of one of these schools is Summerhill School in Britain, although this would not be the best example of what I personally would advocate, for one they could get rid of the private aspect of the school.
The authority of staff and teachers is limited, and the methods used to deal with problems that may arise is one of diplomacy as opposed to punishment, with a staff, or older pupil as a mediator. Lessons and subject taking is voluntary, as in you can choose which subject(s) to take, meaning that children are not forced into unnecessary stress over subjects which they couldn't care less about and are likely to forget everything they are taught in it once they leave school anyway, that also allows pupils to hone their skills in whatever subject they prefer, leading to a better educated population, individuals specialising in certain subjects, or a subject (and this doesn't have to be the usual, physics, maths, geography, but may, or should also include craftsmanship, scaffolding, art and such like). It also allows children the time off to relax and de-stress if need be whenever they like, which would increase their educational potential when they do return to the classroom.
Decisions over matters concerning the school are to be taken collectively, with the pupils and staff members deciding them together, obviously with the staff members helping to inform students in matters also. Good luck by the way!
"The class war begins in the desecration of our ancestors: millions of people going to their graves as failures, forever denied the experience of a full human existence, their being was simply cancelled out. The violence of the bourgeoisie's appropriation of the world of work becomes the structure that dominates our existence. As our parents die, we can say truly that their lives were for nothing, that the black earth which is thrown down onto them blacks out our sky."
